DirectDraw + zooming
Author
Hi all,
I have a world which is just 1 bitmap. What is the easiest way to zoom so only a part of that world is visible in my surface?
Thanks!

By 'surface' I assume you mean 'Destination Surface'. Call the DestSurface::Blt method using a destination RECT large enough that the image is stretched to the desired size.
NOTE: Making entire worlds out of a single bitmap is generally a bad idea. Use a tile-map.

Hi,
This is the first time I am working with DirectDraw, so every tip is appreciated.
I have already implemented the zoom function using the Draw() function with SrcRect and DestRect. It is working very well!
I am going to find out how tilemaps are working. If you have any nice links, could you please post them here?
Thanks!

I did a quick search for tilemaps. It sounds good to use them, however, I have a question.
This is my engine (don't look at the ugly grass, need to fix that one):
View example
If you look to the water, it is an animation (you cannot see in the image though). I have an array. Loaded all bitmaps into the array and created surfaces for each one of them. I draw them one by one so I can get a nice animation for the sea (as well for other objects, for example the weather icons).
Can I still use the animations when using tile-maps?
Thanks!

Follow this link. Under the subcategory 'General' you will find a series called 'Game Programming Genesis'. That might be a very good start. And to answer you animation question: Yes it can be done and is explained in the series I just showed.
Another good place is GameDev.net's articles section (link is a top of nearly evey page). Look into Isometric and Tile-based Games. And don't forget the Isometric and Tile-based forum.
Hope that helps.
