Question by Muzz 1 · Mar 27, 2011 at 01:43 PM · javascriptfpsforceconstantforce

Constant force question

Simply, I need to add a constant force to a FPS controller. However, with constant forces, if a camera is attatched to the object, it does not work. So how can I achieve this? I could probably do it without a constant force, but to script something that gives that effect. So is this a better idea?

Well, constant force acts upon a rigidbody. You could add a rigidbody and a collider to your camera.

If you want to move something constantly forward without physics:

ConstantVelocity.js

var velocity : Vector3;

function Update() { transform.position += velocity * Time.deltaTime; }

ConstantAcceleration.js

var acceleration : Vector3; var velocity : Vector3;

function Update() { velocity += acceleration Time.deltaTime; transform.position += velocity Time.deltaTime; }

If you're using a Character Controller:

ConstantCharacterVelocity.js

var velocity : Vector3; private var controller : CharacterController;

function Awake() { controller = GetComponent(CharacterController); }

function Update() { controller.SimpleMove(velocity); }
