That sounds like a nice feature.
If I've understood correctly, you want to be able to add different images to a TiledBackground object (like frames in sprite objects) and have the TiledBackground pick a random frame for each tile. I think that could be useful, but it would have to be added. The object could have a property where you could choose if the order should be random or not.
The best way I can think of is adding several instances of a Sprite object with different frames, and pick a random frame through events. But I know that's not what you're looking for.
Maybe you should make a suggestion in the "C2 General" subforum. If you don't, I think I will. <img src="smileys/smiley20.gif" border="0" align="middle" />
Yes, you understood correctly ;)
Maybe Scirra can create this new feature, would be awesome..
Can be called something like 'Random tiled background' ;D
I will suggest that and hope I get some support from u guys ;)
