Weather-based Erosion

[jdrueckert]

Overview

The weather should play a role in the world-gen topic "Erosion". Wind erosion can occur without any precipitation, of course, but rain also causes erosion. This can probably use the same system as developed for other erosion causes, just speed up the rate of erosion when it is precipitating. Furthermore, the rate of erosion should be increased when snow/water is melting/freezing/etc.

Notes

It might be interesting to edit FlowingLiquids so that some degree of erosion occurs when liquids flow. That would need to be tested to make sure it doesn't look too weird, though (and it could cause issues with block mining - perhaps blocks need an "erosion factor" so that they don't appear to have decreased until a certain amount of erosion has occurred?).

Tasks

• Change the pace of erosion for precipitation-affected areas
• Add "erosion factor" to block data
• Make erosion factor increase when liquids (FlowingLiquids) travel over the block
• Eventually (when "erosion factor" reduced to zero), have the block break and/or move to a spot of lower erosion
