AddForce to sphere

I have a sphere with rigid body, (Is Kinematic = False) and Configurable Joint (Configured in World Space = True); using AddForce(0, 500, 0). The sphere’s movement still depends on it’s rotation.

#pragma strict

var moveSpeedX = 15;
var maxSpeedX = 15;

var baseSpeed = 0;

var jumpForce1 = 450.00;
var jumpForce2 = 200.00;


private var doubleJump : boolean = true;
private var grounded : boolean = false;


function Update()
{
	
	if(Physics.Raycast(transform.position, -transform.up, 1)) {
      grounded = true;
      doubleJump = true;
   } else
      grounded = false;
	if(Input.GetButtonDown("Jump")) {
		if(grounded) {
		rigidbody.AddForce(0, jumpForce1, 0);
        }
      else if(doubleJump) {
         doubleJump = false;
         transform.rigidbody.AddForce(0, jumpForce2, 0);
      }
      
		
	}
	
		
	if(Input.GetKey(KeyCode.LeftArrow)) {
		if (transform.rigidbody.velocity.x > -maxSpeedX) {
			transform.rigidbody.velocity.x = transform.rigidbody.velocity.x - (2*moveSpeedX) *Time.deltaTime;
		}  else {
			transform.rigidbody.velocity.x = -maxSpeedX;
		}
	}
	if(Input.GetKey(KeyCode.RightArrow)) {
		if (transform.rigidbody.velocity.x < maxSpeedX) {
			transform.rigidbody.velocity.x = transform.rigidbody.velocity.x + (2*moveSpeedX) *Time.deltaTime;
		}  else {
			transform.rigidbody.velocity.x = maxSpeedX;
		
		}
		
	}
}

Also tried using: rigidbody.AddForceAtPosition(myForward * 1000.0, rigidbody.worldCenterOfMass); That didn’t work either. Sorry for question that a million noobs like me have already asked, but I can’t get it to work.

rigidbody.AddForce(…) should work as expected. But your raycast should look like this:

if(Physics.Raycast(transform.position, -Vector3.up, 1))

I also recommend you to use:

rigidbody.AddForce(0, jumpForce1, 0, ForceMode.VelocityChange);
rigidbody.AddForce(0, jumpForce2, 0, ForceMode.VelocityChange)

so you can set the speed independently from the sphere’s previous velocity (like SuperMario does) and the sphere’s mass. Thus you must tweak your jumpForces again.

good luck :wink:
