window_shape

Quick links: documentation · itch.io
Platforms: Windows, Windows (YYC)​
Versions: GM:S 1.4, GMS2.2, GMS2.3/GM2022+

This extension lets you use custom window shapes in your GameMaker projects!

Ellipses, rectangles, polygons, complex shapes - anything goes.

Good for software, virtual pets, or more novel game ideas
(e.g. BLAWK used my Desktop Screenshots extension to make a "hole" in a game window, but now you can have a real, click-through hole).

What's interesting here

As more and more boilerplate gets automated through GmlCppExtFuncs, extensions are left to be fairly normal-looking C++ code.

The only thing left to do is forwarding C++ enums (which aren't even enums in WinAPI's case) to GML - currently I have to make an enum with plain numbers (which GmxGen will convert into GML constants) and write a bunch of static_asserts to ensure that each value matches its C++ counterpart.
