While Button Pressed

Hey there,

this problem sounds pretty easy to solve, but.... I don't get it.

I want to have a kind of loop that counts up the variable "acceleration" WHILE the space bar is pressed.And them when it is not pressed anymore I want to add a relative Force to the ball.

rigidbody.AddRelativeForce (Vector3.forward * acceleration);

So how do I write a counter, which counts while a button is pressed, and then, when it isn't anymore, it does whatever I want?

(For Example the Pinball game of windows)

It tried a while loop, which crashed my game several times...

var power = 0.0;

var forceToAdd = 5.0;

function Update ()
{
if(Input.GetButton("Jump"))
   {
   power += forceToAdd * Time.deltaTine;
   }

   if(Input.GetButtonUp("jump"))
   {
   rigidbody.AddRelativeForce(Vector3.forward * power);
   }
}

Simple, adds to the power variable when the Jump button is down. When it is released we add force to the rigidbody.

Let me know if there are any errors :)

oh well there is small error

there is: power += forceToAdd * Time.deltaTine;

should be: power += forceToAdd * Time.deltaTime;

Time not Tine.

no errors, worked well :) , thx a lot
