Clipping a sprite

by John Pritchett · in Torque Game Builder · 07/20/2005 (11:59 am) · 3 replies

Is there a simple method to clip a sprite? For example, suppose I have a sprite that's 100 pixels long, with a bar that's centered and 80 pixels long. Now suppose I want to truncate that bar so that only the left half is visible. This seems like a simple task for a clipping rectangle on the sprite, but I don't see anything like this in the docs. Can anyone point me in the right direction?

Thanks!

    What about altering the UV coords?
    Obviously thats if you are doing stuff in C++.

    If so then you could just use UV range of u=0.5, v=1.0 instead of u=1.0,v=1.0?

    Hmm... that could actually be integrated nicely into the T2D code by
    having say a clip rect that affected the underlying U,V coords.

    Which would allow e.g having a progress bar, etc by just adjusting the cliprect
    in X as well as a ton of other ideas.

    Basically like masks in Macromedia Flash.

    Melv?
