I don't understand how to scroll a sprite with command :
- SetSpriteUVOffset
- SetSpriteUV

I have an image with size 800px width and 400 px height and I want the image scroll looped in the direction U.

It's possible?

Some help????

Yes, you need to first set the image to wrap the UVs (using SETIMAGEWRAPU and SETIMAGEWRAPV commands), then you can scroll the image with SETSPRITEUVOFFSET.

Sorry Diegs! Sure thing! Here's a quick example:



You'll need to supply your own myimage.png in the media folder. Hope this helps!

p.s. there are examples for SetImageU and V in the help too.

Here's another example, animated progress bar.

And if you need help to remember which point is which in the UV data (as I often do), I have a simple image in my tutorial I reference often to remind myself.

If you really want to get fancy with UV data:

animated grass
