Repeating background?

[Bonafide]

Hey guys,

I'm wondering if there is a simple way of redrawing a background once it begins to run out of the View rectangle, or if it was possible to set an image as the background of a window/screen.

One more question. What's the method to check if there is a mouse click on a certain part of an image (e.g. a title screen, and I want to click on play or options, etc.)?

None. You need to check yourself if the position of the click is on your sprite.

There's no method to tile an image/sprite, but you can easily do that on your own. Two simple for loops that increment by the proper image dimension each cycle and run as long as the loop counter variable is inside the view rectangle.

Setting a "background image" isn't possible directly. Instead you just draw a sprite over the whole screen each frame.

Actually, the really efficient way to implement a repeating pattern is to use OpenGL.  You just set up the small backdrop image as the current texture and draw a large quad.

If you don't know OpenGL programming, then you're better off with the double-nested loop.
