How to move rigidbody Diagonal with movePosition
var player :Transform;
var speed = 10;
private var direction = Vector3(0,0,0);
private var grounded = 0;
function Update () {
walking = speed * Time.deltaTime;
if(Input.GetKey("w"))
player.rigidbody.MovePosition(player.position + player.forward * walking);
if(Input.GetKey("d"))
player.rigidbody.MovePosition(player.position + player.right * walking);
if(Input.GetKey("a"))
player.rigidbody.MovePosition(player.position + player.right * -walking);
if(Input.GetKey("s"))
player.rigidbody.MovePosition(player.position + player.forward * -walking);
if(Input.GetKey("w") && (Input.GetKey("d")))
player.rigidbody.MovePosition(player.position + player.forward.right * Time.deltaTime);
}
there's my whole script so far, and i have seen other for controlling rigidbodys, but i dont what to have a script i cant understand so im making my own, i don't want to use add Force, but if i dont then there is no diagonal its either straight or sideways. how do i make a dagonal?
It's a lot easier if you use GetAxis ins$$anonymous$$d of a bunch of keys.
For some reason my reply didn't show up, despite the message saying that it was waiting for approval dissapearing.
Anyway, it was basically this. You can declare a temporary Vector3 called movement. WASD adds +1 in the direction the buttons correspond to to this vector.
then normalize the vector and multiply it with your speed. And then use moveposition. $$anonymous$$uch simpler than adding && comparisons for every possible button combination.
Vector3 movement;
if (Input.GetKey (KeyCode.W)) {
movement = movement + transform.forward;
}
if (Input.GetKey (KeyCode.S)) {
movement = movement - transform.forward;
}
if (Input.GetKey (KeyCode.A)) {
movement = movement + transform.TransformDirection (Vector3.left);
}
if (Input.GetKey (KeyCode.D)) {
movement = movement + transform.TransformDirection (Vector3.right);
}
movement = Vector3.Normalize (movement);
movement = movement * speed;
rigidbody.MovePosition (transform.position + movement*Time.fixedDeltaTime);
Accumulate a 'delta' in a Vector3, then apply it with MovePosition at the end
Could you help me understand that better, i am kind of a noob in scripting, also if it is a Vector3, wouldn't it be the world-wide x,y,z coordinates, they need to be local.
Yes, please help me understand what you are saying!
