add force to direction

[junglejapes]

so what I have is a script that calculates the angle from the player to the mouse. It works just fine. Right is 0/360, up is 90, left is 180, down is 270.

I wanted to take that angle and use it with addforce to sort of make the character jump at the mouse… Nothing seems to be working.

v3Pos = Input.mousePosition;
v3Pos.z = (playerObject.transform.position.z - cameraObject.transform.position.z);
v3Pos = cameraObject.ScreenToWorldPoint(v3Pos);
v3Pos = v3Pos - playerObject.transform.position;
jumpRotation = Mathf.Atan2 (v3Pos.y, v3Pos.x) * Mathf.Rad2Deg;

if (Input.GetMouseButtonUp(0))
{
playerObject.AddForce(dir * force);;
}

I’m returning an error:
Assets/PlayerMover.js(21,30): BCE0023: No appropriate version of ‘UnityEngine.Rigidbody.AddForce’ for the argument list ‘(int)’ was found.

Please help.

Actually you don’t need the angle at all. Just do:

playerObject.AddForce(v3Pos * factor);

or

playerObject.AddForce(v3Pos.normalized * factor);

‘factor’ will be a variable you declare and likely need a value of in the range of 200 - 1500. The first line of code will result in more force being added if the object is further away. The second suggested line will add the same amount of force no matter the distance.

playerObject is a gameObject. It needs to be a RigidBody value type to use AddForce

i just use this :
rb.AddForce(transform.TransformDirection(Vector3.back).normalized * forceValue, ForceMode.VelocityChange);

and the directions using Vector3.back (forward, left, right)
