hmm what


« Posted 2013-08-04 00:35:30 »

Hello, I have been working on making random maps and am having a problem with my code. I decided to put the diamond step in a try and catch so if its doing a point next to the edge it will switch to doing 3 known points. Its not working for some reason and I'm not grasping why. Its when I use map[x - midX][y] thats the problem. If I take out the try catch and just use all the alternative ones it works but has some artifacts. I got some code and pictures. Also I wonder why the stupid thing only has water coming from the left in every one I open. Any help will be much appreciated.

This what it looks like using 3 points


What happens when I add a fourth

I'm upset I didn't capitalize the H in my name...

Use simplex noise?

It provides much nicer terrain, has no (noticable) artifacts, and can be configured easily for different types of landscape, even within the same world.

This may help

If you still struggle to get your head around it (I still don't fully understand it. I only understand how perlin noise works), just copy the code out by hand.
You may still learn something.
