C&C Project - Big Maps Memory
I'm hoping the C&C tilemaps can get pretty big. Red Alert maps are typically these sizes: 64x64 (32kb), 96x96 (72kb), 126x64 (about 63kb), and 64x126. That is using 8bits for each tile cell. This doesn't take into account anything else for the map, like objects, buildings, triggers etc. but just the terrain graphics layer.
This will give a limit of 256 unique C&C tiles per map, which I hope will be enough. If it's not I may have to just byte the bullet and use more memory, but we'll see.
Ok I hope most of this makes sense! It may not be the best approach, but I want to free as much VRAM memory as possible for graphics. I need to cram a lot of sprites in there too!
I had some screenies to bring in today but I forgot - sorry guys hopefully I'll have them tommorow.
