Script to make an object always face the camera?

I'm making a game witch uses 2d sprites on a 3d environment. I have the sprite as a texture on a plane and I have the plane rotated 90 degrees on the x axis. How would I go about making a script so the z axis changes to always face the camera. Also is it possible to change textures on an object with scripts?

 

Take a look here http://unity3d.com/support/documentation/ScriptReference/Transform.LookAt.html for information on making something look at a specific point.

You can alter most any aspect of a mesh via script. You can access texture information via the material on an object. Check out http://unity3d.com/support/documentation/ScriptReference/Material.html

 

There's a script in the Wiki for doing this:

You can probably just set the Z axis to be the only one that changes and that should work.

 

Thanks for posting this, I'm new to the forums and this helped me out a great bit

 

It seems that the link is broken?
