Rotation Object Follow Help

Questions & Answers
1

Before I was having problems with writing a script that would follow an object by rotating towards it on one axis… like a plane. I got something figured out, it works flawlessly except that it can’t turn all the way around it seems like 180 is the limit and it can’t follow targets behind itself. Any way I can fix this. Here’s my code:

#pragma strict

var target : GameObject;
var startRot : Quaternion;

var rotSpeed : float;

function Start () {

startRot = transform.rotation;

}

function Update () {

if(target != null){
	
	var rotation = Quaternion.LookRotation(transform.position - target.transform.position);
	transform.rotation = Quaternion.Slerp (transform.rotation, rotation, rotSpeed * Time.deltaTime);
	
	var eulerAngles = transform.rotation.eulerAngles;
	
	eulerAngles.y = startRot.eulerAngles.y;
	eulerAngles.z = startRot.eulerAngles.z;
		
	// Set the altered rotation back
	transform.rotation = Quaternion.Euler(eulerAngles);

}

is this top down?
like say asteroids
If so you want to rotate on the global up axis which is

(0,1,0)

or

vector3.up

if its viewed from the front ala side scroller like mario

(technically mario could have been made in a 3d program with the camera actually above or whatever)

But basically if its in front of the camera and teh camera is looking forward that axis is

vector3.forward

Basically what 2 dimensions are we working with here?

because the rotational axis is the third dimension.

Hi,
I dont know on which axis you want the object to rotate

Use this to rotate on Y axis only

//add this in Update function

transform.eulerAngles = Vector3(0,transform.eulerAngles.y,0);
