Generating Exhumed River Channel
I recently did some work in generating rivers in a 2d game. Revisiting this work to create an exhumed river channel, I decided it might be fun to revisit how to generate it to make the channel look more realistic. Instead of using a drunken walker, this is a more expensive but interesting map generator: Start by generating 2d simplex noise where less <0.6 is floor rest is walls Generate terminal lines at each map exit (north, south, east, west). Shuffle those lines and randomly choose a start and end location for the river based on two of those lines. Later you can add another line with terminal point to allow a split river channel ...
