Question by mlpfimguy · May 20, 2018 at 01:32 PM · physicsforcelag

Script doesn't work with framerate drop

Hey everyone! I have this script which adds force to the player when a button is pressed. Works great when the framerate is smooth, but doesn't work at all when the game slows down by any amount.

Any idea what would cause this?

 var player: GameObject; 
 
 var force : float = 10.0f; 
 var forceUp : float = 20.0f;
 
 function Update () {
     qtePic1.active = true;
     qtePic2.active = false;
     delayBefore();
 
     //qtePic.active = false;
 
     if(Input.GetKey(KeyCode.Z)){ //getkey
 
         player.GetComponent.<Rigidbody>().AddForce(transform.forward * force);
         player.GetComponent.<Rigidbody>().AddForce(transform.up * forceUp);
 
         player.GetComponent.<Rigidbody>().AddForce(transform.forward * force, ForceMode.Impulse);
         player.GetComponent.<Rigidbody>().AddForce(transform.up * forceUp, ForceMode.Impulse);
     }

Don't call anything physics related from Update(). Use FixedUpdate() instead. That'll alleviate some of the frame issues.
