I'm writing a monster AI that has some aspects of group mentality for my game. My first question is what would be the best way to make a heatmap in unity for migration patterns and such. I can figure out lots of things on my own, but I would like some steering in the right direction.
Basically, I need a perlin-noise-esque map with hot/cold based on location and season that has fluctuations between different hot and cold zones over time. I don't know if there's a way to do this with just prelin noise, since all I've seen it do is random 2D maps. Any help would be appreciated.
Oh, and I prefer any code in c#, but it's not a necessity.
