Help: Uncaught ReferenceError: MovementScript is not defined in movement

var FirstPersonMovement = pc.createScript(‘firstPersonMovement’);

MovementScript.prototype.update = function(dt) {
I need help

Hey and welcome, you have defined the script with name FirstPersonMovement and using the function property with the different name i.e. MovementScript.

Just replace the word MovementScript with FirstPersonMovement and it will work fine.

ok thank you
