Ok the development but the exported executables don't work

Ok, looking at the drive export folder, the .exe and the .pck in it are reported by the google drive ti be 0 bytes. That does seem wrong.

edit: never mind, I was looking at storage used rather than size. Doh.

edit2: Tried launching the exported game and it just popped up a generic godot window and then closed again. Same when trying to launch it from CLI. One thought that comes to my mind is that you might have forgot to set the startup scene perhaps?

Look in Project > Project Settings > Application > Run > Main Scene

Took some time for the drive to zip it up, but downloaded the project folder.

The startup scene was defined. I installed export template and exported with debug on, this is the output when launching the exported executable from console:

As you can read there is a resource res://Sprites/Tiles/DirtAutoTile.png which causes the startup scene to fail from loading. So I wasn't too far off.

Ok, so it's a bug in godot resource loader!

From the above errors you see that godot is searching for res://Sprites/Tiles/DirtAutoTile.png while your asset is res://sprites/Tiles/DirtAutoTile.png. The difference is subtle.

If you navigate to Project > Tools > Orphan Resource Explorer You should be able to see a list of assets and a white circle/point icon next to their right. Clicking on that you can see where the assets are located according to godot and try to reload/fix the paths to anything that's wrong.

OK, I'm ready to make another guess here: You copied folders from one project to another and then renamed the base folders within root folder which had capitalized first letter to have lower case first letters instead and that caused all these problems.

edit: manually went through the whole project and fixed all assets that had the wrong case in the resource path. Once I fixed all of them and re-exported the game guess what? It worked. :smile:
