This is a bit different than with Radarr, the way it is configured is by setting “Release profiles”. I took the profiles from TRaSH: WEB-DL Release profile regex. The only possible change I’ll do is disable the Low Quality Groups and/or the “Golden rule” filter (for x265 encoded video).

For me it ended up looking like this:

Once you click on “Add X” it will add it to the Series section and will start as monitored. So far I haven’t noticed that it immediately starts downloading (because of the “Start search for missing episodes” setting) but I always click on unmonitor the series, so I can manually check (again, due to the low quality of my indexers).

When it automatically starts to download an episode/season it will send it to qBitTorrent and you can monitor it over there. Else you can also monitor at Activity -> Queue. Same thing goes if you download manually each episode/season via the interactive search.

To interactively search episodes/seasons go to Series and then click on any series, then click either on the interactive search button for the episode or the season, it is an icon of a person as shown below:

      Indexers
      
 
      For Jackett, an indexer is just a configured tracker for some of the commonly known torrent sites. Jackett comes with a lot of pre-configured public and private indexers which usually have multiple URLs (mirrors) per indexer, useful when the main torrent site is down. Some indexers come with extra features/configuration depending on what the site specializes on.
      
 
      To add an indexer click on the “+ Add Indexer” at the top of the Web UI and look for indexers you want, then click on the “+” icon on the far-most right for each indexer or select the ones you want (clicking on the checkbox on the far-most left of the indexer) and scroll all the way to the bottom to click on “Add Selected”. They then will show as a list with some available actions such as “Copy RSS Feed”, “Copy Torznab Feed”, “Copy Potato Feed”, a button to search, configure, delete and test the indexer, as shown below:

      Now it’s time to actually create the game, by creating the basic scenes that will make up the game. The hardest part and the most confusing is going to be the TileMaps, so that goes first.

      TileMaps

      I’m using a scene called WorldTiles with a Node2D node as root called the same. With 2 different TileMap nodes as children named GroundTileMap and PipeTileMap (these are their own scene); yes 2 different TileMaps because we need 2 different physics colliders (in Godot 4.0 you can have a single TileMap with different physics colliders in it). Each node has its own script. It should look something like this:

      -
      +
      Scene - WorldTiles (TileMaps)
      Scene - WorldTiles (TileMaps)

      I used the following directory structure:

      -
      +
      Scene - WorldTiles - Directory structure
      Scene - WorldTiles - Directory structure

      To configure the GroundTileMap, select the node and click on (empty) on the TileMap/Tile set property and then click on New TileSet, then click where the (empty) used to be, a new window should open on the bottom:

      -
      +
      TileSet - Configuration window
      TileSet - Configuration window

      Click on the plus on the bottom left and you can now select the specific tile set to use. Now click on the yellow + New Single Tile, activate the grid and select any of the tiles. Should look like this:

      -
      +
      TileSet - New single tile
      TileSet - New single tile

      We need to do this because for some reason we can’t change the snap options before selecting a tile. After selecting a random tile, set up the Snap Options/Step (in the Inspector) and set it to 16x16 (or if using a different tile set, to it’s tile size):

      -
      +
      TileSet - Tile - Step snap options
      TileSet - Tile - Step snap options

      Now you can select the actual single tile. Once selected click on Collision, use the rectangle tool and draw the rectangle corresponding to that tile’s collision:

      -
      +
      TileSet - Tile - Selection and collision
      TileSet - Tile - Selection and collision

      Do the same for the other 3 tiles. If you select the TileMap itself again, it should look like this on the right (on default layout it’s on the left of the Inspector):

      -
      +
      TileSet - Available tiles
      TileSet - Available tiles

      The ordering is important only for the “underground tile”, which is the filler ground, it should be at the end (index 3); if this is not the case, repeat the process (it’s possible to rearrange them but it’s hard to explain as it’s pretty weird).

      At this point the tilemap doesn’t have any physics and the cell size is wrong. Select the GroundTileMap, set the TileMap/Cell/Size to 16x16, the TileMap/Collision/Layer set to bit 2 only (ground layer) and disable any TileMap/Collision/Mask bits. Should look something like this:

      -
      +
      TileMap - Cell size and collision configuration
      TileMap - Cell size and collision configuration

      Now it’s just a matter of repeating the same for the pipes (PipeTileMap), only difference is that when selecting the tiles you need to select 2 tiles, as the pipe is 2 tiles wide, or just set the Snap Options/Step to 32x16, for example, just keep the cell size to 16x16.

      Default ground tiles

      I added few default ground tiles to the scene, just for testing purposes but I left them there. These could be place programatically, but I was too lazy to change things. On the WorldTiles scene, while selecting the GroundTileMap, you can select the tiles you want to paint with, and left click in the grid to paint with the selected tile. Need to place tiles from (-8, 7) to (10, 7) as well as the tile below with the filler ground (the tile position/coordinates show at the bottom left, refer to the image below):

      -
      +
      Scene - WorldTiles - Default ground tiles
      Scene - WorldTiles - Default ground tiles

      Player

      On a new scene called Player with a KinematicBody2D node named Player as the root of the scene, then for the children: AnimatedSprite as Sprite, CollisionShape2D as Collision (with a circle shape) and 3 AudioStreamPlayers for JumpSound, DeadSound and HitSound. Not sure if it’s a good practice to have the audio here, since I did that at the end, pretty lazy. Then, attach a script to the Player node and then it should look like this:

      -
      +
      Scene - Player - Node setup
      Scene - Player - Node setup

      Select the Player node and set the CollisionShape2D/Collision/Layer to 1 and the CollisionObject2D/Collision/Mask to 2 and 3 (ground and pipe).

      For the Sprite node, when selecting it click on the (empty) for the AnimatedSprite/Frames property and click New SpriteFrames, click again where the (empty) used to be and ane window should open on the bottom:

      -
      +
      Scene - Player - SpriteFrames window
      Scene - Player - SpriteFrames window

      Right off the bat, set the Speed to 10 FPS (bottom left) and rename default to bird_1. With the bird_1 selected, click on the Add frames from a Sprite Sheet, which is the second button under Animation Frames: which looks has an icon of a small grid (next to the folder icon), a new window will popup where you need to select the respective sprite sheet to use and configure it for importing.

      Now it’s time to actually create the game, by creating the basic scenes that will make up the game. The hardest part and the most confusing is going to be the TileMaps, so that goes first.

      TileMaps

      I’m using a scene called WorldTiles with a Node2D node as root called the same. With 2 different TileMap nodes as children named GroundTileMap and PipeTileMap (these are their own scene); yes 2 different TileMaps because we need 2 different physics colliders (in Godot 4.0 you can have a single TileMap with different physics colliders in it). Each node has its own script. It should look something like this:

      -
      +
      Scene - WorldTiles (TileMaps)
      Scene - WorldTiles (TileMaps)

      I used the following directory structure:

      -
      +
      Scene - WorldTiles - Directory structure
      Scene - WorldTiles - Directory structure

      To configure the GroundTileMap, select the node and click on (empty) on the TileMap/Tile set property and then click on New TileSet, then click where the (empty) used to be, a new window should open on the bottom:

      -
      +
      TileSet - Configuration window
      TileSet - Configuration window

      Click on the plus on the bottom left and you can now select the specific tile set to use. Now click on the yellow + New Single Tile, activate the grid and select any of the tiles. Should look like this:

      -
      +
      TileSet - New single tile
      TileSet - New single tile

      We need to do this because for some reason we can’t change the snap options before selecting a tile. After selecting a random tile, set up the Snap Options/Step (in the Inspector) and set it to 16x16 (or if using a different tile set, to it’s tile size):

      -
      +
      TileSet - Tile - Step snap options
      TileSet - Tile - Step snap options

      Now you can select the actual single tile. Once selected click on Collision, use the rectangle tool and draw the rectangle corresponding to that tile’s collision:

      -
      +
      TileSet - Tile - Selection and collision
      TileSet - Tile - Selection and collision

      Do the same for the other 3 tiles. If you select the TileMap itself again, it should look like this on the right (on default layout it’s on the left of the Inspector):

      -
      +
      TileSet - Available tiles
      TileSet - Available tiles

      The ordering is important only for the “underground tile”, which is the filler ground, it should be at the end (index 3); if this is not the case, repeat the process (it’s possible to rearrange them but it’s hard to explain as it’s pretty weird).

      At this point the tilemap doesn’t have any physics and the cell size is wrong. Select the GroundTileMap, set the TileMap/Cell/Size to 16x16, the TileMap/Collision/Layer set to bit 2 only (ground layer) and disable any TileMap/Collision/Mask bits. Should look something like this:

      -
      +
      TileMap - Cell size and collision configuration
      TileMap - Cell size and collision configuration

      Now it’s just a matter of repeating the same for the pipes (PipeTileMap), only difference is that when selecting the tiles you need to select 2 tiles, as the pipe is 2 tiles wide, or just set the Snap Options/Step to 32x16, for example, just keep the cell size to 16x16.

      Default ground tiles

      I added few default ground tiles to the scene, just for testing purposes but I left them there. These could be place programatically, but I was too lazy to change things. On the WorldTiles scene, while selecting the GroundTileMap, you can select the tiles you want to paint with, and left click in the grid to paint with the selected tile. Need to place tiles from (-8, 7) to (10, 7) as well as the tile below with the filler ground (the tile position/coordinates show at the bottom left, refer to the image below):

      -

      Scene - WorldTiles - Default ground tiles

      Player

      On a new scene called Player with a KinematicBody2D node named Player as the root of the scene, then for the children: AnimatedSprite as Sprite, CollisionShape2D as Collision (with a circle shape) and 3 AudioStreamPlayers for JumpSound, DeadSound and HitSound. Not sure if it’s a good practice to have the audio here, since I did that at the end, pretty lazy. Then, attach a script to the Player node and then it should look like this:

      -
      +
      Scene - Player - Node setup
      Scene - Player - Node setup

      Select the Player node and set the CollisionShape2D/Collision/Layer to 1 and the CollisionObject2D/Collision/Mask to 2 and 3 (ground and pipe).

      For the Sprite node, when selecting it click on the (empty) for the AnimatedSprite/Frames property and click New SpriteFrames, click again where the (empty) used to be and ane window should open on the bottom:

      -
      +
      Scene - Player - SpriteFrames window
      Scene - Player - SpriteFrames window

      Right off the bat, set the Speed to 10 FPS (bottom left) and rename default to bird_1. With the bird_1 selected, click on the Add frames from a Sprite Sheet, which is the second button under Animation Frames: which looks has an icon of a small grid (next to the folder icon), a new window will popup where you need to select the respective sprite sheet to use and configure it for importing.

Under the FileSystem window, right click on the fonts directory (create one if needed) and click on New Resource... and select DynamicFontData, save it in the “fonts” directory as SilverDynamicFontData.tres (Silver as it is the font I’m using) then double click the just created resource and set the DynamicFontData/Font Path to the actual Silver.ttf font (or whatever you want).

    Then create a new resource and this time select DynamicFont, name it SilverDynamicFont.tres, then double click to edit and add the SilverDynamicFontData.tres to the DynamicFont/Font/Font Data property (and I personally toggled off the DynamicFont/Font/Antialiased property), now just set the DynamicFont/Settings/(Size, Outline Size, Outline Color) to 32, 1 and black, respectively (or any other values you want). It should look something like this:

    -

    Resource - DynamicFont - Default font
    Resource - DynamicFont - Default font

    Do the same for another DynamicFont which will be used for the score label, named SilverScoreDynamicFont.tres. Only changes are Dynamic/Settings/(Size, Outline Size) which are set to 128 and 2, respectively. The final files for the fonts should look something like this:

    Now, this script in particular will need to be a Singleton (AutoLoad), which means that there will be only one instance and will be available across all scripts. To do so, go to Project -> Project settings… -> AutoLoad and select this script in the Path: and add a Node Name: (I used SavedData, if you use something else, be careful while following this devlog) which will be the name we’ll use to access the singleton.
