int Height(BYTE *pHeightMap,int X,int Y)
{
// Make sure we don''t go past our array size
if(X<0 || X>MAP_SIZE-1) return 0;
if(Y<0 || Y>MAP_SIZE-1) return 0;
//int x = X % MAP_SIZE; // Error check our x value
//int y = Y % MAP_SIZE; // Error check our y value
if(!pHeightMap) return 0; // Make sure our data is valid
// Use the equation: index = (x + (y * arrayWidth) ) to find the current height
return pHeightMap[X+(Y*MAP_SIZE)]; // Index into our height array and return the height
}
if i try to set the value using that index method, i just go out of bounds and debugger starts breaking down and crying about it...
i also tried
pHeightMap[x*z]=whatever;
but that doesnt seem to work...
how do i move through the array to change the value located at point x,z
thanks..
either changing value in 1d array, or switching to 2d array
could someone tell me how to change the value in a 1d array?
im basically loading a raw file into a 1d array, and using it to render height maps. that works great, but now i wanna change some of the height values... i know x and z, and i know what i want to change y to, but how to i go through the array to find the location i wanna change?
here''s how i return values, but it doesnt seem to work for setting them...
