Rivers

Adds rivers, which are flowing bodies of water, and lakes at the ends of them.

 

Rivergen uses 1-100 for config values and this one uses 0-1, if you have lakes everywhere reset your config.

 

Required Worldgen Settings

Oceans are required to generate rivers. 300-500% landcover scale and 50% landcover works good.

 

Where Does The River Go?

The river may come from in-land and flow out to an ocean.

 

Why are there lakes everywhere?

At some point this config setting was changed from an integer to a 0-1 percentage. Delete your config or fix it.

 

API

Once the first part of a chunk is generated (NewGenTerra) some data will be stored inside chunks IF a river is within range of them.

float[] flowVectors:

        Stored inside the chunk at y0, or the bottom chunk of the column. Retrieved with GetModdata("flowVectors"), or ModDataCache.Get() which will not de-serialize it every time it's fetched.

        Index is retrieved by localZ 32 + localX coordinates for the X vector, multiply the index by 2 for the Z vector.

        Available on both the client and the server, used for rendering flowing water and physics.

ushort[] riverDistance:

        Stored inside the column map chunk. Retrieved with GetModdata("riverDistance").

        Index is retrieved by localZ 32 + localX.

        Available on the server, has the distance in blocks from the edge of a river, or 0 if it's inside the river bank.

        There is no caching for this, do not GetModdata in hot paths or cache it yourself.

Config, explanation of settings: https://github.com/glutzer/Rivers-Mod/blob/master/Rivers/src/RiverConfig.cs

Does not work with terra prety unless you also use watersheds which implements this in it's own way and is compatible.
