This extension does not use the surfaces to generate shadows. It uses triangle lists. Extension is GML only, no third party DLL's.

Easy to use, fast, efficient, and compatible with all the target platforms. You can use it with multiple objects to cast shadows in one room. Objects can be moved and / or rotated.

This extension allows you to create shadows for any arbitrary convex objects.

Shadows such as these can be seen in popular games like Phases (Ketchapp), Prism (Appsonite), Exit Zone (Dead Cool Apps), Impossible Caves (Appsolute) and many others.


  • static objects
  • moving objects
  • rotating objects
  • editor object included to create shadow masks easily
  • can change color of the shadow
  • can change alpha of the shadow
  • can display debug lines
  • can use blending for light sprite
  • 3 possible ways to shadow casting objects

Watch the video or download the demo to see the extension in action.

You can also read the readme.txt file (included in the files) to begin using the extension.
