 <p>The game was originally developed with <em>Godot 4.0 alpha 8</em>, but it didn&rsquo;t support HTML5 (webassembly) export&hellip; so I backported to <em>Godot 3.5 rc1</em>.</p>
+<p><ins><mark>Note:</mark> I&rsquo;ve updated the game to <em>Godot 4</em> and documented it on my <a href="https://blog.luevano.xyz/g/flappybird_godot_devlog_2.html">FlappyBird devlog 2</a> entry.</ins></p>
 <p>Not going to specify all the details, only the needed parts and what could be confusing, as the source code is available and can be inspected; also this assumes minimal knowledge of <em>Godot</em> in general. Usually when I mention that a set/change of something it usually it&rsquo;s a property and it can be found under the <em>Inspector</em> on the relevant node, unless stated otherwise; also, all scripts attached have the same name as the scenes, but in <em>snake_case</em> (scenes/nodes in <em>PascalCase</em>).</p>
 <p>One thing to note, is that I started writing this when I finished the game, so it&rsquo;s hard to go part by part, and it will be hard to test individual parts when going through this as everything is depending on each other. For the next devlog, I&rsquo;ll do it as I go and it will include all the changes to the nodes/scripts as I was finding them, probably better idea and easier to follow.</p>

+<p><strong>Disclaimer:</strong> I started the port back in <em>Godot 4.0</em> something and left the project for a while, then opened the project again in <em>Godot 4.1</em>, and it didn&rsquo;t ask to convert anything so probably nowadays the conversion is better.</p>
+<h3 id="general-changes">General changes<a class="headerlink" href="#general-changes" title="Permanent link">&para;</a></h3>
+<p>These include the first changes for fixing some of the conflicting code to at least make it run (no gameplay) as well as project settings adjustments.</p>
+<ul>
+<li>Changing the <a href="https://blog.luevano.xyz/g/flappybird_godot_devlog_1.html#default-import-settings">default import settings</a> for pixel art no longer works (though it&rsquo;s worth to double check as they changed from <code>Texture</code> to a <code>Texture2D</code>). The important parameter to <a href="https://ask.godotengine.org/122518/how-to-import-pixel-art-in-godot-4">change is the <em>Filter</em> for the textures</a>.<ul>
+<li>Since all nodes inherit parameters by default, changing on the parent nodes (or just once in the root such as <code>Main.tscn</code>) will suffice: Go to <em>Inspector -&gt; CanvasItem -&gt; Texture</em> and change <em>Filter</em> from &ldquo;Inherit&rdquo; to &ldquo;Nearest&rdquo;.</li>
+</ul>
+</li>
+<li>Re-set the <em>InputMap</em> as the system probably changed from <em>Godot 3</em> to <em>Godot 4</em>.</li>
+<li>For <code>SavedData</code> singleton, change from <code>File</code> to <code>ConfigFile</code> and refactor. This is really not needed for making it run, but I changed this right away.</li>
+<li>Remove <code>velocity</code> property of <code>Player</code> which is already included in <code>CharacterBody2D</code>.</li>
+<li>Disable all <code>TileMap</code> related code as tile maps have changed drastically, they need more effort to covnert.</li>
+<li>Change <code>String(int)</code> to <code>str(int)</code>.</li>
+</ul>
+<h3 id="player">Player<a class="headerlink" href="#player" title="Permanent link">&para;</a></h3>
+<p>Now that the game at least runs, next thing is to make it &ldquo;playable&rdquo;:</p>
+<ul>
+<li><code>AnimatedSprite</code> changed to <code>AnimatedSprite2D</code> (with the inclusion of <code>AnimatedSprite3D</code>). This node type changed with the automatic conversion.<ul>
+<li>Instead of checking if an animation is playing with the the <code>playing</code> property, the method <code>is_playing()</code> needs to be used.</li>
+</ul>
+</li>
+<li>The <code>default_gravity</code> from the <code>ProjectSettings</code> no longer needs to be multiplied by <code>10</code> to have reasonable numbers. The default is now <code>980</code> instead of <code>98</code>. I later changed this when refactoring the code and fine-tuning the feel of the movement.</li>
+<li>The <em>Collision mask</em> can be changed programatically with the <code>set_collision_mask_value</code> (and similar with the layer). Before, the mask/layer was specified by the <code>bit</code> which started from <code>0</code>, but now it is accessed by the <code>layer_number</code> which starts from <code>1</code>.</li>
+</ul>
+<h3 id="world">World<a class="headerlink" href="#world" title="Permanent link">&para;</a></h3>
+<p>This is the most challenging part as the <code>TileMap</code> system changed drastically, it is basically a <em>from the ground up redesign</em>, luckily the <code>TileMap</code>s I use are really simple. Since this is not intuitive from the get-go, I took some notes on the steps I took to set up the world <code>TileMap</code>.</p>
+<h4 id="scene">Scene<a class="headerlink" href="#scene" title="Permanent link">&para;</a></h4>
+<p>Instead of using one scene per <code>TileMap</code> only one <code>TileMap</code> can be used with multiple <em>Atlas</em> in the <code>TileSet</code>. Multiple physics layers can now be used per <code>TileSet</code> so you can separate the physics collisions on a per <em>Atlas</em> or <em>Tile</em> basis. The inclusion of <em>Tile patterns</em> also helps when working with multiple <em>Tiles</em> for a single cell &ldquo;placement&rdquo;. How I did it:</p>
+<ol>
+<li>Created one scene with one <code>TileMap</code> node, called <code>WorldTileMap.tscn</code>, with only one <code>TileSet</code> as multiple <em>Atlas</em>&lsquo; can be used (this would be a single <code>TileSet</code> in <em>Godot 3</em>).<ul>
+<li>To add a <code>TileSet</code>, select the <code>WorldTileMap</code> and go to <em>Inspector -&gt; TileMap -&gt; TileSet</em> then click on &ldquo;<empty>&rdquo; and then &ldquo;New TileSet&rdquo; button.</li>
+<li>To manipulate a <code>TileSet</code>, it needs to be selected, either by clicking in the <em>Inspector</em> section or on the bottom of the screen (by default) to the left of <em>TileMap</em>, as shown in the image below.</li>
+</ul>
+</li>

+<li>By selecting an atlas and having the &ldquo;Setup&rdquo; selected, change the <em>Name</em> to something recognizable like <code>ground</code> and add the texture atlas (the spritesheet) by dragging and dropping in the &ldquo;<empty>&rdquo; <em>Texture</em> field, as shown in the image below.

Then set the collision&rsquo;s layers and masks accordingly (ground on layer 2, pipe on 3). In my case, based on my already set <a href="https://blog.luevano.xyz/g/flappybird_godot_devlog_1.html#layers">layers</a>.<ul>
+<li>This will enable physics properties on the tiles when selecting them (by selecting the atlas, being in the correct &ldquo;Select&rdquo; section and selecting a tile) and start drawing a polygon with the tools provided. This part is hard to explain in text, but below is an image of how it looks once the polygon is set.</li>

+<p>Basically merged all 3 scripts (<code>ground_tile_map.gd</code>, <code>pipe_tile_map.gd</code> and <code>world_tiles.gd</code>) into one (<code>world_tile_map.gd</code>) and immediatly was able to delete a lot of signal calls between those 3 scripts and redundant code.</p>
+<p>The biggest change in the scripting side are the functions to place tiles. For <em>Godot 3</em>:</p>
+<pre><code class="language-gdscript"># place single tile in specific cell
+void set_cell(x: int, y: int, tile: int, flip_x: bool = false, flip_y: bool = false, transpose: bool = false, autotile_coord: Vector2 = Vector2( 0, 0 ))
+void set_cellv(position: Vector2, tile: int, flip_x: bool = false, flip_y: bool = false, transpose: bool = false, autotile_coord: Vector2 = Vector2( 0, 0 ))
+</code></pre>
+<p>Whereas in <em>Godot 4</em>:</p>
+<pre><code class="language-gdscript"># place single tile in specific cell
+void set_cell(layer: int, coords: Vector2i, source_id: int = -1, atlas_coords: Vector2i = Vector2i(-1, -1), alternative_tile: int = 0)
+# erase tile at specific cell
+void erase_cell(layer: int, coords: Vector2i)
+</code></pre>
+<p>How to use these functions in <em>Godot 4</em> (new properties or differences/changes):</p>
+<ul>
+<li><code>layer</code>: for my case I only use 1 layer so it is always set to <code>0</code>.</li>
+<li><code>coords</code>: would be the equivalent to <code>position</code> for <code>set_cellv</code> in <em>Godot 3</em>.</li>
+<li><code>source_id</code>: which atlas to use (ground: <code>0</code> or pipe <code>1</code>).</li>
+<li><code>atlas_coords</code>: tile to use in the atlas. This would be the equivalent to <code>tile</code> in <em>Godot 3</em>.</li>
+<li><code>alternative_tile</code>: for tiles that have alternatives such as mirrored or rotated tiles, not required in my case.</li>
+</ul>
+<p>Setting <code>source_id=-1</code>, <code>atlas_coords=Vector21(-1,-1)</code> or <code>alternative_tile=-1</code> will delete the tile at <code>coords</code>, similar to just using <code>erase_cell</code>.</p>
+<p>With the addition to <em>Tile patterns</em> (to place multiple tiles), there is a new function:</p>
+<pre><code class="language-gdscript"># place pattern
+void set_pattern(layer: int, position: Vector2i, pattern: TileMapPattern)
+</code></pre>
+<p>Where <code>position</code> has the same meaning as <code>coords</code> in <code>set_cell</code>/<code>erase_cell</code>, not sure why it has a different name. The <code>pattern</code> can be obtained by using <code>get_pattern</code> method on the <code>tile_set</code> property of the <code>TileMap</code>. Something like:</p>
+<pre><code class="language-gdscript">var pattern: TileMapPattern = tile_set.get_pattern(index)
+</code></pre>
+<p>Other than that, <code>Vector2</code> needs to be changed to <code>Vector2i</code>.</p>

+<p>General changes and additions that have nothing to do with porting to <em>Godot 4</em>, things I wanted to add regardless of the version.</p>
+<h3 id="audio">Audio<a class="headerlink" href="#audio" title="Permanent link">&para;</a></h3>
+<p>The audio in the <em>Godot 3</em> version was added in the last minute and it was blasting by default with no option to decrease the volume or mute it. To deal with this:</p>
+<ol>
+<li>Refactored the code into a single scene/script to have better control.</li>
+<li>Added a volume control slider by following <a href="https://www.gdquest.com/tutorial/godot/audio/volume-slider/">this GDQuest guide</a>.</li>
+<li>Added a mute button, following the same principle as with the volume control.</li>
+</ol>
+<p>The basic code required for these features is the following:</p>
+<pre><code class="language-gdscript"># get audio bus index
+var audio_bus_name: String = &quot;Master&quot;
+var _bus: int = AudioServer.get_bus_index(audio_bus_name)
+
+# change the volume
+var linear_volume: float = 0.5 # 50%, needs to be between 0.0 and 1.0
+var db_volume: float = linear_to_db(linear_volume)
+AudioServer.set_bus_volume_db(_bus, db_volume)
+
+# mute
+AudioServer.set_bus_mute(_bus, true) # false to unmute
+</code></pre>
+<p>Just be careful with how the <code>linear_volume</code> is set (from a button or slider) as it has to be between <code>0.0</code> and <code>1.0</code>.</p>
+<h3 id="event-bus">Event bus<a class="headerlink" href="#event-bus" title="Permanent link">&para;</a></h3>
+<p>Moved all the signal logic into an event bus to get rid of the coupling I had. This is accomplished by:</p>
+<ol>
+<li>Creating a singleton (autoload) script which I called <code>event.gd</code> and can be accessed with <code>Event</code>.</li>
+<li>All the signals are now defined in <code>event.gd</code>.</li>
+<li>When a signal needs to be emited instead of emitting the signal from any particular script, emit it from the event bus with <code>Event.&lt;signal_name&gt;.emit(&lt;optional_args&gt;)</code>.</li>
+<li>When connecting to a signal instead of taking a reference to where the signal is defined, simply connect it with with <code>Event.&lt;signal_name&gt;.connect(&lt;callable&gt;[.bind(&lt;optional_args&gt;)])</code><ul>
+<li>For signals that already send arguments to the callable, they do not need to be specified in <code>bind</code>, only extras are needed here.</li>
+</ul>
+</li>
+</ol>
+<h3 id="ui">UI<a class="headerlink" href="#ui" title="Permanent link">&para;</a></h3>
+<p>Really the only UI I had before was for rendering fonts, and the way fonts work changed a bit. Before, 3 resources were needed as <a href="https://blog.luevano.xyz/g/flappybird_godot_devlog_1.html#fonts">noted in my previous entry</a>:</p>
+<ol>
+<li>Font file itself (<code>.ttf</code> for example).</li>
+<li><code>DynamicFontData</code>: used to point to a font file (<code>.ttf</code>) and then used as base resource.</li>
+<li><code>DynamicFont</code>: usable in godot control nodes which holds the <code>DynamicFontData</code> and configuration such as size.</li>
+</ol>
+<p>Now only 1 resource is needed: <code>FontFile</code> which is the <code>.ttf</code> file itself or a godot-created resource. There is also a <code>FontVariation</code> option, which takes a <code>FontFile</code> and looks like its used to create fallback options for fonts. The configuration (such as size) is no longer held in the font resource, but rather in the parent control node (like a <code>Label</code>). Double clicking on the <code>.ttf</code> file and disabling antialiasing and compression is something that might be needed. Optionally create a <code>FontLabelSettings</code> which will hold the <code>.ttf</code> file and used as base for <code>Label</code>s. Use &ldquo;Make Unique&rdquo; for different sizes. Another option is to use <em>Themes</em> and <em>Variations</em>.</p>
+<p>I also created the respective volume button and slider UI for the added audio functionality as well as creating a base <code>Label</code> to avoid repeating configuration on each <code>Label</code> node.</p>
+<h3 id="misc">Misc<a class="headerlink" href="#misc" title="Permanent link">&para;</a></h3>
+<p>Small changes that don&rsquo;t affect much:</p>
+<ul>
+<li>Updated <code>@export</code> to <code>@export_range</code>. The auto conversion didn&rsquo;t use the correct annotation and instead used a comment.</li>
+<li>Refactored the <code>game_scale</code> methodolgy as it was inconsistent. Now only one size is used as base and everything else is just scaled with the <code>root</code> <code>Window</code>.</li>
+<li>Got rid of the FPS monitoring, was only using it for debugging purposes back then.</li>
+</ul>

+      <content:encoded><![CDATA[<p>As stated in my <a href="https://blog.luevano.xyz/g/flappybird_godot_devlog_1.html">FlappyBird devlog 1</a> entry I originally started the clone in <em>Godot 4</em>, then backported back to <em>Godot 3</em> because of HTML5 support, and now I&rsquo;m porting it back again to <em>Godot 4</em> as there is support again and I want to start getting familiar with it for future projects.</p>

+<p><strong>Disclaimer:</strong> I started the port back in <em>Godot 4.0</em> something and left the project for a while, then opened the project again in <em>Godot 4.1</em>, and it didn&rsquo;t ask to convert anything so probably nowadays the conversion is better.</p>
+<h3 id="general-changes">General changes<a class="headerlink" href="#general-changes" title="Permanent link">&para;</a></h3>
+<p>These include the first changes for fixing some of the conflicting code to at least make it run (no gameplay) as well as project settings adjustments.</p>
+<ul>
+<li>Changing the <a href="https://blog.luevano.xyz/g/flappybird_godot_devlog_1.html#default-import-settings">default import settings</a> for pixel art no longer works (though it&rsquo;s worth to double check as they changed from <code>Texture</code> to a <code>Texture2D</code>). The important parameter to <a href="https://ask.godotengine.org/122518/how-to-import-pixel-art-in-godot-4">change is the <em>Filter</em> for the textures</a>.<ul>
+<li>Since all nodes inherit parameters by default, changing on the parent nodes (or just once in the root such as <code>Main.tscn</code>) will suffice: Go to <em>Inspector -&gt; CanvasItem -&gt; Texture</em> and change <em>Filter</em> from &ldquo;Inherit&rdquo; to &ldquo;Nearest&rdquo;.</li>
+</ul>
+</li>
+<li>Re-set the <em>InputMap</em> as the system probably changed from <em>Godot 3</em> to <em>Godot 4</em>.</li>
+<li>For <code>SavedData</code> singleton, change from <code>File</code> to <code>ConfigFile</code> and refactor. This is really not needed for making it run, but I changed this right away.</li>
+<li>Remove <code>velocity</code> property of <code>Player</code> which is already included in <code>CharacterBody2D</code>.</li>
+<li>Disable all <code>TileMap</code> related code as tile maps have changed drastically, they need more effort to covnert.</li>
+<li>Change <code>String(int)</code> to <code>str(int)</code>.</li>
+</ul>
+<h3 id="player">Player<a class="headerlink" href="#player" title="Permanent link">&para;</a></h3>
+<p>Now that the game at least runs, next thing is to make it &ldquo;playable&rdquo;:</p>
+<ul>
+<li><code>AnimatedSprite</code> changed to <code>AnimatedSprite2D</code> (with the inclusion of <code>AnimatedSprite3D</code>). This node type changed with the automatic conversion.<ul>
+<li>Instead of checking if an animation is playing with the the <code>playing</code> property, the method <code>is_playing()</code> needs to be used.</li>
+</ul>
+</li>
+<li>The <code>default_gravity</code> from the <code>ProjectSettings</code> no longer needs to be multiplied by <code>10</code> to have reasonable numbers. The default is now <code>980</code> instead of <code>98</code>. I later changed this when refactoring the code and fine-tuning the feel of the movement.</li>
+<li>The <em>Collision mask</em> can be changed programatically with the <code>set_collision_mask_value</code> (and similar with the layer). Before, the mask/layer was specified by the <code>bit</code> which started from <code>0</code>, but now it is accessed by the <code>layer_number</code> which starts from <code>1</code>.</li>
+</ul>
+<h3 id="world">World<a class="headerlink" href="#world" title="Permanent link">&para;</a></h3>
+<p>This is the most challenging part as the <code>TileMap</code> system changed drastically, it is basically a <em>from the ground up redesign</em>, luckily the <code>TileMap</code>s I use are really simple. Since this is not intuitive from the get-go, I took some notes on the steps I took to set up the world <code>TileMap</code>.</p>
+<h4 id="scene">Scene<a class="headerlink" href="#scene" title="Permanent link">&para;</a></h4>
+<p>Instead of using one scene per <code>TileMap</code> only one <code>TileMap</code> can be used with multiple <em>Atlas</em> in the <code>TileSet</code>. Multiple physics layers can now be used per <code>TileSet</code> so you can separate the physics collisions on a per <em>Atlas</em> or <em>Tile</em> basis. The inclusion of <em>Tile patterns</em> also helps when working with multiple <em>Tiles</em> for a single cell &ldquo;placement&rdquo;. How I did it:</p>
+<ol>
+<li>Created one scene with one <code>TileMap</code> node, called <code>WorldTileMap.tscn</code>, with only one <code>TileSet</code> as multiple <em>Atlas</em>&lsquo; can be used (this would be a single <code>TileSet</code> in <em>Godot 3</em>).<ul>
+<li>To add a <code>TileSet</code>, select the <code>WorldTileMap</code> and go to <em>Inspector -&gt; TileMap -&gt; TileSet</em> then click on &ldquo;<empty>&rdquo; and then &ldquo;New TileSet&rdquo; button.</li>
+<li>To manipulate a <code>TileSet</code>, it needs to be selected, either by clicking in the <em>Inspector</em> section or on the bottom of the screen (by default) to the left of <em>TileMap</em>, as shown in the image below.</li>
+</ul>
+</li>
+</ol>

+<li>By selecting an atlas and having the &ldquo;Setup&rdquo; selected, change the <em>Name</em> to something recognizable like <code>ground</code> and add the texture atlas (the spritesheet) by dragging and dropping in the &ldquo;<empty>&rdquo; <em>Texture</em> field, as shown in the image below. Take a not of the <em>ID</em>, they start from <code>0</code> and increment for each atlas, but if they&rsquo;re not <code>0</code> and <code>1</code> change them.</li>

Then set the collision&rsquo;s layers and masks accordingly (ground on layer 2, pipe on 3). In my case, based on my already set <a href="https://blog.luevano.xyz/g/flappybird_godot_devlog_1.html#layers">layers</a>.<ul>
+<li>This will enable physics properties on the tiles when selecting them (by selecting the atlas, being in the correct &ldquo;Select&rdquo; section and selecting a tile) and start drawing a polygon with the tools provided. This part is hard to explain in text, but below is an image of how it looks once the polygon is set.</li>

+<ol start="8">
+<li>Create a tile pattern by drawing the tiles wanted in the editor and then going to the <em>Patterns</em> tab (to the right of <em>Tiles</em>) in the <em>TileMap</em>, selecting all tiles wanted in the pattern and dragging the tiles to the <em>Patterns</em> window. Added patterns will show in this window as shown in the image below, and assigned with IDs starting from <code>0</code>.</li>

+<h4 id="script">Script<a class="headerlink" href="#script" title="Permanent link">&para;</a></h4>
+<p>Basically merged all 3 scripts (<code>ground_tile_map.gd</code>, <code>pipe_tile_map.gd</code> and <code>world_tiles.gd</code>) into one (<code>world_tile_map.gd</code>) and immediatly was able to delete a lot of signal calls between those 3 scripts and redundant code.</p>
+<p>The biggest change in the scripting side are the functions to place tiles. For <em>Godot 3</em>:</p>
+<pre><code class="language-gdscript"># place single tile in specific cell
+void set_cell(x: int, y: int, tile: int, flip_x: bool = false, flip_y: bool = false, transpose: bool = false, autotile_coord: Vector2 = Vector2( 0, 0 ))
+void set_cellv(position: Vector2, tile: int, flip_x: bool = false, flip_y: bool = false, transpose: bool = false, autotile_coord: Vector2 = Vector2( 0, 0 ))
+</code></pre>
+<p>Whereas in <em>Godot 4</em>:</p>
+<pre><code class="language-gdscript"># place single tile in specific cell
+void set_cell(layer: int, coords: Vector2i, source_id: int = -1, atlas_coords: Vector2i = Vector2i(-1, -1), alternative_tile: int = 0)
+# erase tile at specific cell
+void erase_cell(layer: int, coords: Vector2i)
+</code></pre>
+<p>How to use these functions in <em>Godot 4</em> (new properties or differences/changes):</p>
+<ul>
+<li><code>layer</code>: for my case I only use 1 layer so it is always set to <code>0</code>.</li>
+<li><code>coords</code>: would be the equivalent to <code>position</code> for <code>set_cellv</code> in <em>Godot 3</em>.</li>
+<li><code>source_id</code>: which atlas to use (ground: <code>0</code> or pipe <code>1</code>).</li>
+<li><code>atlas_coords</code>: tile to use in the atlas. This would be the equivalent to <code>tile</code> in <em>Godot 3</em>.</li>
+<li><code>alternative_tile</code>: for tiles that have alternatives such as mirrored or rotated tiles, not required in my case.</li>
+</ul>
+<p>Setting <code>source_id=-1</code>, <code>atlas_coords=Vector21(-1,-1)</code> or <code>alternative_tile=-1</code> will delete the tile at <code>coords</code>, similar to just using <code>erase_cell</code>.</p>
+<p>With the addition to <em>Tile patterns</em> (to place multiple tiles), there is a new function:</p>
+<pre><code class="language-gdscript"># place pattern
+void set_pattern(layer: int, position: Vector2i, pattern: TileMapPattern)
+</code></pre>
+<p>Where <code>position</code> has the same meaning as <code>coords</code> in <code>set_cell</code>/<code>erase_cell</code>, not sure why it has a different name. The <code>pattern</code> can be obtained by using <code>get_pattern</code> method on the <code>tile_set</code> property of the <code>TileMap</code>. Something like:</p>
+<pre><code class="language-gdscript">var pattern: TileMapPattern = tile_set.get_pattern(index)
+</code></pre>
+<p>Other than that, <code>Vector2</code> needs to be changed to <code>Vector2i</code>.</p>

+<p>General changes and additions that have nothing to do with porting to <em>Godot 4</em>, things I wanted to add regardless of the version.</p>
+<h3 id="audio">Audio<a class="headerlink" href="#audio" title="Permanent link">&para;</a></h3>
+<p>The audio in the <em>Godot 3</em> version was added in the last minute and it was blasting by default with no option to decrease the volume or mute it. To deal with this:</p>
+<ol>
+<li>Refactored the code into a single scene/script to have better control.</li>
+<li>Added a volume control slider by following <a href="https://www.gdquest.com/tutorial/godot/audio/volume-slider/">this GDQuest guide</a>.</li>
+<li>Added a mute button, following the same principle as with the volume control.</li>
+</ol>
+<p>The basic code required for these features is the following:</p>
+<pre><code class="language-gdscript"># get audio bus index
+var audio_bus_name: String = &quot;Master&quot;
+var _bus: int = AudioServer.get_bus_index(audio_bus_name)
+
+# change the volume
+var linear_volume: float = 0.5 # 50%, needs to be between 0.0 and 1.0
+var db_volume: float = linear_to_db(linear_volume)
+AudioServer.set_bus_volume_db(_bus, db_volume)
+
+# mute
+AudioServer.set_bus_mute(_bus, true) # false to unmute
+</code></pre>
+<p>Just be careful with how the <code>linear_volume</code> is set (from a button or slider) as it has to be between <code>0.0</code> and <code>1.0</code>.</p>
+<h3 id="event-bus">Event bus<a class="headerlink" href="#event-bus" title="Permanent link">&para;</a></h3>
+<p>Moved all the signal logic into an event bus to get rid of the coupling I had. This is accomplished by:</p>
+<ol>
+<li>Creating a singleton (autoload) script which I called <code>event.gd</code> and can be accessed with <code>Event</code>.</li>
+<li>All the signals are now defined in <code>event.gd</code>.</li>
+<li>When a signal needs to be emited instead of emitting the signal from any particular script, emit it from the event bus with <code>Event.&lt;signal_name&gt;.emit(&lt;optional_args&gt;)</code>.</li>
+<li>When connecting to a signal instead of taking a reference to where the signal is defined, simply connect it with with <code>Event.&lt;signal_name&gt;.connect(&lt;callable&gt;[.bind(&lt;optional_args&gt;)])</code><ul>
+<li>For signals that already send arguments to the callable, they do not need to be specified in <code>bind</code>, only extras are needed here.</li>
+</ul>
+</li>
+</ol>
+<h3 id="ui">UI<a class="headerlink" href="#ui" title="Permanent link">&para;</a></h3>
+<p>Really the only UI I had before was for rendering fonts, and the way fonts work changed a bit. Before, 3 resources were needed as <a href="https://blog.luevano.xyz/g/flappybird_godot_devlog_1.html#fonts">noted in my previous entry</a>:</p>
+<ol>
+<li>Font file itself (<code>.ttf</code> for example).</li>
+<li><code>DynamicFontData</code>: used to point to a font file (<code>.ttf</code>) and then used as base resource.</li>
+<li><code>DynamicFont</code>: usable in godot control nodes which holds the <code>DynamicFontData</code> and configuration such as size.</li>
+</ol>
+<p>Now only 1 resource is needed: <code>FontFile</code> which is the <code>.ttf</code> file itself or a godot-created resource. There is also a <code>FontVariation</code> option, which takes a <code>FontFile</code> and looks like its used to create fallback options for fonts. The configuration (such as size) is no longer held in the font resource, but rather in the parent control node (like a <code>Label</code>). Double clicking on the <code>.ttf</code> file and disabling antialiasing and compression is something that might be needed. Optionally create a <code>FontLabelSettings</code> which will hold the <code>.ttf</code> file and used as base for <code>Label</code>s. Use &ldquo;Make Unique&rdquo; for different sizes. Another option is to use <em>Themes</em> and <em>Variations</em>.</p>
+<p>I also created the respective volume button and slider UI for the added audio functionality as well as creating a base <code>Label</code> to avoid repeating configuration on each <code>Label</code> node.</p>
+<h3 id="misc">Misc<a class="headerlink" href="#misc" title="Permanent link">&para;</a></h3>
+<p>Small changes that don&rsquo;t affect much:</p>
+<ul>
+<li>Updated <code>@export</code> to <code>@export_range</code>. The auto conversion didn&rsquo;t use the correct annotation and instead used a comment.</li>
+<li>Refactored the <code>game_scale</code> methodolgy as it was inconsistent. Now only one size is used as base and everything else is just scaled with the <code>root</code> <code>Window</code>.</li>
+<li>Got rid of the FPS monitoring, was only using it for debugging purposes back then.</li>
+</ul>]]></content:encoded>

 <p>The game was originally developed with <em>Godot 4.0 alpha 8</em>, but it didn&rsquo;t support HTML5 (webassembly) export&hellip; so I backported to <em>Godot 3.5 rc1</em>.</p>

 <p>Not going to specify all the details, only the needed parts and what could be confusing, as the source code is available and can be inspected; also this assumes minimal knowledge of <em>Godot</em> in general. Usually when I mention that a set/change of something it usually it&rsquo;s a property and it can be found under the <em>Inspector</em> on the relevant node, unless stated otherwise; also, all scripts attached have the same name as the scenes, but in <em>snake_case</em> (scenes/nodes in <em>PascalCase</em>).</p>
 <p>One thing to note, is that I started writing this when I finished the game, so it&rsquo;s hard to go part by part, and it will be hard to test individual parts when going through this as everything is depending on each other. For the next devlog, I&rsquo;ll do it as I go and it will include all the changes to the nodes/scripts as I was finding them, probably better idea and easier to follow.</p>
