1. How can I load a dds-file or a png-file from a resource? 2. My main sprites-image (png-format) has these dimensions now: 512 * 5424 With sprites in it of 32 * 48. Is that a good size to convert to dds?
3. First I had this problem with bitblt, but now I'm working with DX I have it with DX. :P
Can someone please give me an example-code for an rpg-engine that can do this? And I want it accurate by the pixel. I saw other rpg's with collision-detection that were accurate by the tile, but I want it by the pixel...
For the collision, it is only complicated by not necessarily knowing the offset the player's feet make. If you keep a Z-Order of objects in your scene you can do collision testing based on it. In this case, if Player.ZOrder > Wall.ZOrder, Check For Collision With Player.Bottom - Offset, Else Check For Collision With Player.Bottom. It sort of depends on how you are rendering your Sprites, generally I would imagine that you have Rectangle coordinates for the space they take up on the screen...
I cannot help you with the first two since I have moved on to XNA...
