perlin-noise

While working on my 2D tile based game, I encountered a problem. I use Perlin Noise to generate the terrain. Some biomes (Desert, Forest, etc) have different flatness values depending on terrain, which causes the end/start of a new biome to have a big cliff because the terrain is different. When 2 biomes have the same flatness, they are fine, but if they are different, this can happen. Is there any way to keep this from happening?

My game uses the Content Pipeline to load the spriteSheet at runtime. The artist for the game sends me the modified spritesheet and I do a build in my machine and send him an updated project. So I'm looking for a way to generate the xnb files in his machine (this is the output of the content pipeline)… >>> More

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
