Camera Facing Billboards

Hello all,

I've noticed that all the billboard scripts here: http://wiki.unity3d.com/index.php?title=CameraFacingBillboard have really weird rotation when using an RTS camera... so I threw this together and thought I'd share.

Code (csharp):

1.  
2. //  RTSBillboard.cs
3. using UnityEngine;
4.  
5. public class RTSBillboard : MonoBehaviour {
6.     Quaternion offset = Quaternion.Euler(-270, 0, 0);
7.    
8.     void Awake(){
9.     }
10.  
11.     void Update(){
12.         Transform cam = Camera.main.transform;
13.         Quaternion rot = cam.rotation*offset;  
14.         transform.rotation = rot;
15.     }
16. }
17.  

The other billboards are excellent for a grounded / first person camera, but they just don't work for things like health bars on units. Feel free to optimize. I've only been learning C# for a couple of weeks -- I expect criticism.

 

What kind of billboard would you use for something like an image of a tree, rather than actual models?

 

I think you'd probably stick with one of the conventional billboards on the Wiki, as it might look a bit silly for the base of the tree to detach from the ground as the camera increases the height angle.

 

Awesome! Thanks @webgovernor!
