Hi

I've got two simple bacground images connected next to each other. Would like to scroll horizontal.

How do I setup the Image wrap, so that it repeats after displaying the second image. At the moment the setdefaultWrap, repeat after displaying the first image.

Any ideas?

means one image?

u make the sprite as wide as you want
then use a scale to repeat the image inside the sprite
SetSpriteUVScale ( iSpriteIndex, scaleU, scaleV )

SetDefaultWrapU 1 for repeat (U=X)
SetDefaultWrapV 0 clamp (V=Y)
better this
SetImageWrapU ( iImageIndex, mode )
SetImageWrapV ( iImageIndex, mode )

you can scroll the image also with u 0-1,else move the sprite
SetSpriteUVOffset ( iSpriteIndex, u, v )

if the background image is opaque use
SetSpriteTransparency( iSpriteIndex, mode ) 0=off, its faster.

If you look at the help for SetSpriteUVOffset(), you'll see that it is better to having a number of scrolling sprites, rather than scrolling textures. There are too many caveats to make texture scrolling work successfully in most scenarios. As one sprite scrolls off the end of the visible screen, you can wrap it around to the other side again.

Thanks for this BatVink.

Will look into SetSpriteUVOffset() more detail.
