Syntax
minetest.spawn_tree(pos, tree)Description
Spawns an L-system tree at position pos, using the tree definition tree.
See Introduction to L-system trees for a description of L-system trees.
Example
This code adds a chat command that spawns an apple tree with its origin at the current position of the player, assuming that Minetest Game is used:
local treedef = {
axiom="FFFFFAFFBF",
rules_a="[&&&FFFFF&&FFFF][&&&++++FFFFF&&FFFF][&&&----FFFFF&&FFFF]",
rules_b="[&&&++FFFFF&&FFFF][&&&--FFFFF&&FFFF][&&&------FFFFF&&FFFF]",
trunk="default:tree",
leaves="default:leaves",
angle=30,
iterations=2,
random_level=0,
trunk_type="single",
thin_branches=true,
fruit_chance=10,
fruit="default:apple"
}
core.register_chatcommand("spawn_tree", {
params = "", description = "Spawns tree at player position",
func = function(name, param)
local pos = minetest.get_player_by_name(name):getpos()
minetest.chat_send_player(name, "Spawning tree at " .. minetest.pos_to_string(pos)
.. ", please wait")
minetest.spawn_tree(pos, treedef)
return true, "successfully spawned"
end,
})The resulting tree may look like this:
Notes
VanessaE's plants_lib mod (github) provides functions to register L-system trees to be spawned during map generation, and finds places for them to spawn based on the map seed and biome.
