FOSS gamedev and creative worlds

This mod adds weather nodes at worldgen time and then uses an after_destruct callback to re-position the node if it is ever destroyed or found in the wrong position by an abm.
This re-positioning function attempts to preserve the node in preference to accuracy, due to the finite nature if these nodes.
Nodes can be destroyed by having a -+100 block vertical column centered on the weather node and will not be re-populated.

If using on an old world, there is an abm in dry.lua of weather_nodes with can be used to populate the world, however this abm is very performance intensive - far beyond this mod.

This mod add a lot of nodes to the world, so during weather fps can halve or worse

This mod also can cause some abm performance issues;On my system:

• Normal SEnv Step(Minetest Game) ~ 0.05
• Normal Load SEnv Step ~ 0.06 - 0.09
• Normal Peak Load SEnv Step ~ 0.1 - 0.15
• Absolute Peak Load (all weather nodes are moved) SEnv Step ~ 0.3 - 0.5
