[britzl]

Creating the Windows .ico file is a recurring issue that users are struggling with

And so on. The recommended solution is to use an online tool to convert to the .ico format. While this is an ok solution I honestly don't think it is good enough. We should be able to accept one or more images, set in game.project, and create the correct .ico file.

It should be possible to achieve this quite easily using image4j:

This is a low priority issue though.

I'd like to add that the online tools suggested on the website (ICOConvert and AConvert) did not actually work for me, Defold did not use any of the icons. I had to open the file in IcoFX to disable the "compress images for Vista" option as outlined here and then make sure it also exported the sizes 64x64, 96x96 and 128x128 which IcoFX doesn't do by default.

While having Defold generate the .ico file automatically would definitely be preferable, it might be enough (at least temporarily) to make it compatible with the files generated by the online tools.
