Godot Icon

Godot Icon is tool for replacing godot Windows icon. It simplifies current workflow as it does not need any external tools other than Godot itself and can be used on any operating system.

It consists of two scripts: one for generating user customized icon from series of png images and second for replacing default icon in the .exe file.

If you need GUI version of this tool, you can find it in Godot Asset Library or on GitHub

Approach with rcedit is cumbersome and does not work with projects which embed pck into executable. It's because the size of default icon and customized one almost always differ. After replacement Godot cannot find the embedded pck and shows an error. There's also need to create the icon, probably using magick.

Godot Icon fixes above issues by creating icons which are always the same size in terms of disk size. It is posible because produced icons are not compressed. As these custom icons are uncompressed, the size of unpacked executable grows about 200 kB. Typically it should not be a problem because games are almost always distributed in some compressed form.

Using Godot Icon is simple. Download two scripts (no need to download the whole project):
CreateIcon.gd for Godot 4.x
CreateIcon.gd for Godot 3.x
and
ReplaceIcon.gd for Godot 4.x
ReplaceIcon.gd for Godot 3.x

How to use it

Workflow is very simple. If you have only one png prepared run first script in command line like this:

godot -s CreateIcon.gd customized.ico customized.png

Call it like this when you have six required resolutions:

godot -s CreateIcon.gd customized.ico customized1.png customized2.png ...

Then use created icon with your exported project:

godot -s ReplaceIcon.gd customized.ico MyProject.exe

When you provide multiple files to icon creator remember that they should be in sizes: 16x16, 32x32, 48x48, 64x64, 128x128 and 256x256 pixels.
