Infinite Jump Problem

This is not the usual double jump problem people have. I have a game which I started developing for PC and than I decided to switch to Android. Everything worked fine on PC but once I switched to Android the jump began giving me problems. The ball used to be able to jump once only but now it can jump in the air. Not the infinite type jumping into the sky but the ball is able to jump right before it hits the ground. If the ground is -20 in the y axis the ball is able to jump once it is in -19 in the y axis. Here is the ball control code :

Code (JavaScript):

1.  
2. #pragma strict
3. var rotationSpeed = 100;
4. var jumpHeight = 5;
5.  
6. private var isFalling = false;
7.  
8. function Update () {
9.  
10.     //Handle ball rotation.
11.     var rotation : float = Input.acceleration.x * rotationSpeed;
12.     rotation *= Time.deltaTime;
13.     rigidbody.AddRelativeTorque (Vector3.back * rotation);
14.  
15.     for (var touch : Touch in Input.touches) {
16.         if((touch.phase != TouchPhase.Ended && touch.phase != TouchPhase.Canceled) && Physics.Raycast(transform.position, -Vector3.up, 1) && isFalling == false){
17.             rigidbody.velocity.y = jumpHeight;  
18.         }
19.     }
20.  
21. }
22.  
23. function OnCollisionStay (){
24.  
25.     isFalling = false;
26.  
27. }

 

You could try putting your physics code into FixedUpdate() rather than Update().

 

I'll try that thanks.

 

That doesn't change anything.

 

your "isFalling" is always false.. try putting "isFalling= true" inside your "if condition" right below "rigidbody.velocity.y= jumpHeight;"

this might help.

 

Still with the same problem. Thanks for trying.
