DESCRIPTION: Adds the function to spawn nodes near certain nodes and away from others on world generate
VERSION: 0.5
LICENCE: WTFPL
FORUM: http://forum.minetest.net/viewtopic.php?id=4612
Instructions
habitat:generate(node, surfaces, minp, maxp, height_min, height_max, spread, habitat_size, habitat_nodes, antitat_size, antitat_nodes)
* height is the altitude between the node spawns
* spawn near habitat nodes
* avoids antitat nodes
* spread determines how near they spawn next to eachother
Example (from plants mod)
habitat:generate("plants:lavender_wild", {"default:dirt_with_grass"}, minp, maxp, -10, 60, 4, 4, {"default:sand",})
TODO
1.1
* Make node string argument nodes array that spawns random nodes in array
Changelog
1.0
* Reduce amount of loops even more by changing surfaces array to surface string
0.5
* changed function definition (name)
* Improved for loop. Less looping and node checking
0.1
* Spawn plants on generate
