Hi @MATURE! The first line of the script is missing. Please compare the first line of your script with the first line of another script.

Hi, @MATURE .
It looks like the object “Jump” is not defined in the code, or it can’t be found.

To define it, add this line at the start of your code.
var Jump = pc.createScript('jump');
