Question by Darwin Mecharov · Apr 06, 2014 at 03:21 AM · rigidbodyjumpaddforcestartupontriggerstay

How do I stop an object from jumping VERY high at first?

Hi guys! So I have a problem with my player GameObject. Every time I do my "Jump" command at the start of the game, it manages to jump ridiculously high. But after that, it starts jumping normally again. Is there some way I can prevent that from happening? Thank you in advance. Oh, and here's my "Jump" command script:

var Jumped = false;

var JumpHeight = 7500f;

 function Update ()
 {
     if(Input.GetKey(KeyCode.Space) && !Jumped)
     {
         Jumped = true;
         rigidbody.AddForce(Vector3.up * JumpHeight * Time.deltaTime);
     }
 }

And here is what I use to prevent jump spamming, its connected with the code above.

 function OnTriggerStay ()
 {
     Jumped = false;
 }

What I've also noticed is that upon starting, the GameObject has a Y coords of 0. But, after the jump, it becomes around -0.00002

You don't need to multiply by Time.deltaTime, so change JumpHeight to 125 and remove Time.deltaTime. If you really care about the -0.00002, you can change the rigidbody collision detection to continuous but this isn't necessary unless your rigidbody moves really really fast.
