How do you create a color zone map. Like retrieving what section of the map you are in based after a colored image. Mainly in the case of terrains.

And great, now I need a terrain generator to make square shaped segments.

Maybe this can help you.

Wow. I'm completely unable to figure out what a "color zone map" is. Maybe it's because I was eating some of the red mushrooms.

VoidRPG uses one. It an image like a colormap, or a light map for terrains, but instead it uses solid color sections to define "zones".

And I need to figure out how I can use this. To find out which zone an entity is in on the terrain.

Oh and the map editor is a 2D Platform Level Mapper. Thanks for trying. But I neede a terrain engine to make a well, terrain. But instead of the natural triangle shaps included. I need them to be cubes and to move uniformaly. As in a grid.

Okay, I got something down, but I need some help with speed optimization. really need help.

I'd like to help you but I don't understand you.

Whats not to understand? Okay, this function takes where the suplied entity is and finds the respective pixel on the supplied image. It then returns the color of that pixel and that determines the "ZONE" # it is in. Okay, but in the second function, all the building entities will change the supplied image based on there positions. So this means, if your close to a building you are in it's players zone. Like property lines. And what I am doing is displaying this supplied image as a texture for the ground.

There is a function in the archives, to find the U and V of a texture, based on an xy position on a polygon. I dunno if that's any use. It's by Birdie or fredborg.

Hmm, that might be useful later.
