Converting direction to Vector2
I have an angle (direction) and I need to move a rectangle in that direction. This is the code I have so far where pos is a rectangle and dir is the direction:
pos.x += Time.deltaTime * 500 * Mathf.Cos(dir);
pos.y += Time.deltaTime * 500 * Mathf.Sin(dir);
When I run it the object goes off in a random direction!
Edit:
I guess this was not clear: dir is a float and pos is a Rect.

It's worth a mention that dir (your angle) should be in radians.
$$anonymous$$y code worked fine after converting dir to radians
It's not random, it's Trigonometric. I don't know if you need that, so try this and see if it's more like what you want:
var p : Vector3;
function Start() p.x = pos.x; p.y = pos.y; p.z = 0;
function Update()
p += Time.deltaTime * 500 * dir;
pos.x = p.x;
pos.y = p.y;
ah yes, sorry, most of the time I see pos, it's position Vector3. Altered code (above)
