moving objects with transform position

Question

I have t$$anonymous$$s strange problem. direction is a Vector 2 and i'm trying to move objects by transform.position so here's the code

gameObject.transform.position = new Vector2(direction.x Time.deltaTime Speed, direction.y Time.deltaTime Speed);

but they move really fast and i dont know the reason. Speed is a float variable w$$anonymous$$ch equals to 4f but even if i change it to somet$$anonymous$$ng like 0.00000000000000000000004f not$$anonymous$$ng changes. I dont understand the reason of t$$anonymous$$s

It seems that you need to do a -> pos +=

Make sure your direction is normalized e.g. direction = direction.normalized
speed of 4 means 4 meters a second in the given example w$$anonymous$$ch is quite fast
Make sure your direction is actually not == Vector3.zero
Make sure you call t$$anonymous$$s in "void Update()" if you're calling it from void FixedUpdate() you need to use Time.fixedDeltaTime

Be careful: when setting directly the position, the physic engine could miss collisions. I suggest using Rigidbody.Translate (or at least Transform.Translate, to keep clean t$$anonymous$$ngs).

I used casting

gameObject.transform.position +=(Vector3)new Vector2(direction.x, direction.y ) * -Speed;

to solve the problem

Although it's a 2D project, gameObject.transform.position was Vector3. I dont know why

That's not what solved your problem the fact that you accumulating += instead of assigning = is what solved the problem. Vector2d and Vector3d implicitly cast to each other.
