I bit off more than I can chew. Here is another stepping stone towards chunk generation: the density functions. I will keep on working towards terrain generation. |

I see you almost have |

Straight from Java lol, i am not entirely sure what they do. seems like they are just reused code for generating splines |

I don't like if someone just copies Java code and then even say that he don't know what the code does. So you said your goal is to have the Plains biome generation working. Do you need everything here for this, Or is something missing ? |
|
Yeah, it's not ideal. I can do a re-write once I have a better idea of everything that is going on. This is needed for all generation, so is a stepping stone to plains generation |
|
Not knowing is a bad way of putting it. I know what they do; they're just reused and are pretty basic so I don't know what to name them |
|
I would like to have good function names at least |
|
Functions have been renamed |
|
noice, can you may fix the conflicts ? |

rebased, should be good |
WIP
This PR has the end goal of generating plains biomes
