For this you need <a href="https://imagemagick.org/index.php">ImageMagick</a> or some other program that can transform <code>png</code> (or whatever file format you used for the icon) to <code>ico</code>. I used [Chocolatey][https://chocolatey.org/] to install <code>imagemagick</code>, then to convert the icon itself used: <code>magick convert icon.png -define icon:auto-resize=256,128,64,48,32,16 icon.ico</code> as detailed in <em>Godot</em>‘s <a href="https://docs.godotengine.org/en/stable/tutorials/export/changing_application_icon_for_windows.html">Changing application icon for Windows</a>.</p> -<h3 id="exporting">Exporting</h3> +<h4 id="exporting">Exporting<a class="headerlink" href="#exporting" title="Permanent link">¶</a></h4> <p>You need to download the templates for exporting as detailed in <em>Godot</em>‘s <a href="https://docs.godotengine.org/en/stable/tutorials/export/exporting_projects.html">Exporting projects</a>. Basically you go to <em>Editor -> Manage Export Templates…</em> and download the latest one specific to your <em>Godot</em> version by clicking on “Download and Install”.</p> <p>If exporting for Windows then you also need to download <code>rcedit</code> from <a href="https://github.com/electron/rcedit/releases/latest">here</a>. Just place it wherever you want (I put it next to the <em>Godot</em> executable).</p> <p>Then go to <em>Project -> Export…</em> and the Window should be empty, add a new template by clicking on “Add…” at the top and then select the template you want. I used HTML5, Windows Desktop and Linux/X11. Really the only thing you need to set is the “Export Path” for each template, which is te location of where the executable will be written to, and in the case of the Windows Desktop template you could also setup stuff like “Company Name”, “Product Name”, “File/Product Version”, etc..</p> |
