Hi there,
I´ve a little problem with DD.
I want to make a game (like Diablo) and I´ve some problems with the background scrolling in DD.
I know how to scroll to one side but I`ve some problems to do it diagonal (two sides at the same time). Could anybody help me?

PS:
Sorry, but I´ve forgotten to mention that I can´t use wide surfaces. This is the reason why I have to do it this way.
To scroll diagonally up and left, just scroll up and then left :D
It's a tile engine, right? How are you doing the scrolling?
The scrolling in one direction is not so complicated. I´ve got the idea from the dx4vb site.
You just use a second rect and blit the first a little bit smaller and on the rest of your monitor you blit the second rect.
My problem is how do you handle the rects for two directions at the same time?

PS:
My original background is bigger than the screen and I divided it into several pictures (800x600).
:confused:
Now you got me confused... can you please explain what you're doing a bit better?
Sorry ;)
OK, imagine you have a picture (2400 x 1800 px), the background.
Many computers don´t support wide surfaces, like mine.
I divide the big picture (2400x1800) in small pictures (800x600) which my computer can display.
In DD I have a rect with the first picture(a which is blitted on my monitor.
I´ve mentioned before that I use the tutorial from dx4vb as a base for my scrolling engine.
Imagine the avatar moves left so I have to scroll to the left:
I have a in my first rect (top=0,left=0,width=800,height=600).
Then I blit my second rect (top=0,left=xyz,width=800-xyz,height=600), with picture b in a loop on the screen.
If this explanation is also confusing to you, then please look up the tutorial from Jack Hoxley (link ^^^).

You don´t get along with it, do you? ;)
