2D platformer jumping that feels good

Questions & Answers
1

I’m currently using the following code for my movement for a 2D platformer. I didn’t want to use any of the character controllers since I’m using RagePixel, I would prefer to try and write something from scratch. My jumps feel a little ‘spacey’ at the moment and I’m not sure how to fix this. I tried playing around with enabling stronger gravity after a few seconds of being in the air and with different velocities but I can’t find anything that feels right.

var isgrounded : boolean = true;

function Update ()
{

  if(Input.GetKey (KeyCode.A))
{
	transform.position.x -= 1.0;
}

if(Input.GetKey (KeyCode.D))
{
	transform.position.x += 1.0;
}
	
  if (Input.GetKey (KeyCode.W) && isgrounded == true)
  {
    rigidbody.AddForce(Vector3.up * 500);
  }
  
}
		
function OnCollisionEnter(theCollision : Collision)
{
	if(theCollision.gameObject.tag == "Floor")
	{
		isgrounded = true;
	}
}

function OnCollisionExit(theCollision : Collision)
{
	if(theCollision.gameObject.tag == "Floor")
	{
		isgrounded = false;
	}
}

Use the Character Controller class or take a look on thar code so you can mimic it.
