Highmap

[Schlammy]

hey guys.

Me and my Team are creating a new gamemode like Adventure Survivel from Bear grylls. We made a map larger then San fierro and now we want to make a minimap of this island. But How? The Game is to slow to render all of the more then 500 thousend Objects. What can i do now?

You can cast a ray from sky to the ground to find what material is at that point using. So if you create a render target, go through every square meter (or some less precise area, like 2x2 or 4x4) of the map, getting the material and drawing a pixel of its color into the render target during the process, the render target will contain the map which you can save into the image file.

dxCreateRenderTarget 
processLineOfSight, testLineAgainstWater --to get the material 
dxDrawRectangle --to draw the pixel 
dxGetTexturePixels --to get the texture data 
fileCreate, fileWrite, fileClose --to write that data into the file 

And remember, when you cast the ray, the local player must be near enough to make sure that objects are loaded.
