Unity 2D Scripted Movement

[gamenovice]

I was wondering how I could get it so that if I say:

WalkUp(3,5)

where 3 is the distance in meters and 5 is the time in seconds, that I could have an object move linearly and uniformly upward for 3 meters/5 seconds and have the method stop moving the character after that command, which may require a stationary Idle method.

Any insight would be great.

MoveObject:

function Start () {
	yield MoveObject.use.Translation(transform, Vector3.up*3, 5.0, MoveType.Time);
}

In simple code without external libraries (sometimes I prefer my own code for simple things, easier to understand and debug than someone else’s)

public class ObjectMover {
    private Vector3 target;
    private Vector3 start;
    private float totalTime = 0; // when set to 0, will not move
    private float currentPosition = 0;

    public void Update() {
        if (totalTime > 0) {
            currentPosition += Time.deltaTime / totalTime; // advance position by the fraction of the total time that passed this last frame
            if (currentPosition >= 1) {
                currentPosition = 1; // don't pass the target
                totalTime = 0; // end the movement when reaching the target
            }
            transform.position = Vector3.Slerp(start, target, currentPosition); // position the object between the start and the target relative to the time passed out of the total time
        }
    }

    public void MoveTowards(Vector3 direction, float distance, float time) {
        target = transform.position + direction.normalized * distance; // set destination location
        totalTime = time; // set time to perform the movement
        if (time == 0) {
            transform.position = target;
        }
    }

    public void CancelMove() {
        totalTime = 0;
    }
}

Not to use it, you would attach the ObjectMover script to any object you wish to be movable this way, and then call it this way to move it up 3 units in 5 seconds, as in your example:

GameObject objectToMove = GameObject.Find("SomeObjectName");
objectToMove.GetComponent<ObjectMover>().MoveTowards(Vector3.up, 3, 5);

Of course you can use object references instead of GameObject.Find.
