So, I'm trying to establish a limiting code that ensures that (relx+x) and (relz+z) doesn't fall off the matrix boundaries. There may be an ARRAY INDEX EXISTS, but there is nothing to determine matrix in-bounds as far as I know, and the current code doesn't seem to adequately check if it is in-bounds.

Basically, I'm grabbing the nearest 5 points and averaging them together against the current, causing the surface to level out.

Previously in the code:

Not a good way to smooth the surface out. You grab your 5 points, average them, then set the new height. However, when you grab your next point, one of the 5 points it uses will be of the new already averaged height, giving inaccurate smoothing results.

You should store all the heights into a temp array, and when averaging your 5 points you pull the data from that temp array but set the height on the actual matrix.

Yeah, I was aware of the numeric bias, but it returned all the same.
Using 25 points by the way, not 5. Bias is much more severe there.

I'll give the temp array thing a shot. Thanks for the idea Phaelax.

Why is this not compiling correctly? Do I have a bad understanding of what ARRAY INDEX VALID does?




This didn't work either... :\


EDIT: Nevermind, fixed it. Bad IF-AND range-thingy.
