camera orbit like star defence

Question

Hi folks!

How Can I do a mouse orbit like this?

The mouse orbit in the standard assets is limited :|, when I'm at the top of the sphere the camera spins!

Tnx a lot :)

Yeah, I could understand you'd have issues using mouse orbit. I suggest you combine Transform.LookAt( Vector3 ), to keep the camera looking at your target, with regular movement scripting.

In untested C#

using UnityEngine; using System.Collections;

public class FreeformMouseOrbit : MonoBehaviour { public Transform target; public float desiredDistance = 10.0f;

 // should be used for all camera-movement scripts
 public void LateUpdate()
 {
     // focus camera on target
     transform.LookAt( target.position );

     // ... use science to figure out direction of travel relative to camera (up, right, down, left, or a combination)
     Vector3 movementVector = science;

     // move in that direction
     transform.position += movementVector;

     // if you have problems with zoom, move the camera so that it's the appropriate distance from the target
     float actualDistance = Vector3.Distance( transform.position, target.position );
     if( !Mathf.Approximately( desiredDistance, actualDistance ) )
     {
         Vector3.MoveTowards( transform.position, target.position, Mathf.Abs( actualDistance - desiredDistance ) );
     }
 }

}

Now in untested JS:

// FreeformMouseOrbit.js public var target : Transform; public var desiredDistance : float = 10.0;

// should be used for all camera-movement scripts public function LateUpdate() : void { // focus camera on target transform.LookAt( target.position );

 // ... use science to figure out direction of travel relative to camera (up, right, down, left, or a combination)
 var movementVector : Vector3 = science;

 // move in that direction
 transform.position += movementVector;

 // if you have problems with zoom, move the camera so that it's the appropriate distance from the target
 var actualDistance : float = Vector3.Distance( transform.position, target.position );
 if( !Mathf.Approximately( desiredDistance, actualDistance ) )
 {
     Vector3.MoveTowards( transform.position, target.position, Mathf.Abs( actualDistance - desiredDistance ) );
 }

}
