Hey guys, I'm trying to figure out how to generate tileable fractals in code (for game maps, but that's irrelevant) I've been trying to modify the Solid Noise plug-in shipped with GIMP (with my extremely limited understanding of how the code works) but I cant get mine to work correctly.

My modified code so far (Java)

GIMP's solid noise module that I'm basing my code off of (C)

Here is what I'm trying to achieve but This is what I'm getting

So if anybody can see what I've done wrong, or has a suggestion how I could go about doing it differently, I'd greatly appreciate it. Thanks in advance. And if I'm asking way to much or if just a huge failure at life, I apologize.

I am writing a 2d game that uses tile-based top-down graphics to build the world (i.e. the ground plane). Manually made this works fine.
