Following on from the discussion in this thread, SSH has made a Shadow module for AGS 2.72.

Caveats:

  • Shadows ignore walkable areas, because they're done with RawDraw
  • Animated backgrounds also mess up
  • Scrolling rooms: no idea, but wouldn't be surprised if they also don't work.

If you want to avoid these problems, use the dummy character Follow method described in the other thread.

Any suggestions to work around the caveats is welcome.
