Help using Vector2.MoveTowards
I want my enemy to move towards the player and for now I just dropped this in FixedUpdate() to test it out.
The problem is it changes Z axis for some reason and is far away from visible.
Here is the code:
transform.position = Vector2.MoveTowards(transform.position, Player.transform.position, moveSpeed * Time.deltaTime);
The Player and the Enemy are at the same world Z axis(-1940.75) so I don't understand why it's changing so much or at all. It should just be changing X and Y, especially because it's a vector2.
The Player is a child object where as the Enemy is not a child of anything. I do have the correct GameObject referenced.
Hi @knobblez, setting transform.position (a Vector3) equal to a Vector2 will default the z component to 0. So if your player is not already at z = 0, it will immediately move to z = 0 from this code.
Is there a reason not to use Vector3.MoveTowards? That would be easiest, but you could always do something like this if you truly want to disregard z for this type of movement:
Vector2 tempVector2 = Vector2.MoveTowards(transform.position, Player.transform.position, moveSpeed * Time.deltaTime);
transform.position = new Vector3(tempVector2.x, tempVector2.y, transform.position.z);
Hope that helps!
That did the trick! I want to keep the Enemy a couple points below the Z axis of the Player so that the Player is always on top. Thank you for your help!
Glad I could help, good luck with your project!
hmm. I think transform.position is a Vector3. Maybe try casting that to a Vector2 first, before passing it to Vector2.MoveTowards? Here is an example:
Vector2 v2 = new Vector2(transform.position.x, transform.position.y);
Vector2 v2Player = new Vector2(Player.transform.position.x, Player.transform.position.y);
transform.position = Vector2.MoveTowards(v2, v2Player, moveSpeed * Time.deltaTime);
That didn't work - same result. I appreciate the reply though
Sorry mate.
I am using this tweening library (it has a free version): http://dotween.demigiant.com/documentation.php
It has a Do$$anonymous$$oveX and Do$$anonymous$$oveY, where you can explicitly move individual x and y components. It seems to work well for me - see if that is an option for your project?
DO$$anonymous$$oveX/DO$$anonymous$$oveY(float to, float duration, bool snapping) $$anonymous$$oves the target's position to the given value, tweening only the chosen axis (note that in case of rigidbodies, the other axes will still be "locked" by the tween).
