When I attempt to run this, clicking the right arrow causes the entire project to error out. It throws an "undefined value" error. Coming from the update function going all the way down to the "gml_Script_numeric_springing" function at line 166.

I've been glossing over the code and can't seem to find where the undefined variable is.

First, make sure you have GameMaker 2.3 or later.

Secondly, can you post the entire error message? That would help me to identify! Thank you.

I'm on the latest version of GM (2022.8.1.37)

This was very helpful! I've added a new version that should resolve this. shove() required 2 arguments, but only one is supplied by default. I've made all arguments optional with the new version.

Thanks for your feedback and patience. Please let me know if this version works for you.

Thanks for the quick fix. I plan on using this in a jam game. I'll drop a link when I get it finished.

I'd love to see it! Thanks for using Sprite_Effect()!
