Sprite_Effect() for GameMaker

This is a asset for GameMaker containing a script and some examples that allows you to have custom sprite effects that don't interfere with collision! These effects are perfect for conveying motion, so use them both on sprites with no animation, or sprites with multiple frames!

After setting up the correct events, you can simply call one of three functions to get an effect:

shove(x,y) "shoves" the sprite in any direction, then it'll snap back into place. Press the RIGHT arrow key to shove the blue character in the example.

flick(angle) "flicks" the sprite to any angle, then it'll snap back into place. Press the UP arrow key to flick the hearts in the example.

stretch(x, y) "stretches" the sprite to any scale, then it'll snap back into place. Press the DOWN arrow key to stretch the slime in the example.

The download contains a .yymp that can be imported into GameMaker. Also included are instructions, but you can also view the included video.
NOTE: THIS ASSET IS ONLY COMPATIBLE WITH GAMEMAKER 2.3 AND LATER
