I have an idea: remove all trunks and leaves 8 nodes above the dirt. I wrote simple code but I've done something wrong and all trees disappearing. Could you help me?

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: minetest.register_abm({ nodenames = {"default:tree", "default:leaves"}, interval = 0, chance = 1, action = function(pos) for r = -8, 0 do local current_node = { x = pos.x, y = pos.y + r, z = pos.z } if(minetest.env:get_node(current_node).name ~= "default:dirt") then minetest.env:remove_node(pos) end end end })

Thanks in advance

Code: Select all: minetest.register_abm({ nodenames = {"default:tree", "default:leaves"}, interval = 0, chance = 1, action = function(pos) -- check for dirt within 8 nodes down for r = -8, 0 do local current_pos = {x = pos.x, y = pos.y + r, z = pos.z} local current_node = minetest.env:get_node(current_pos).name if(current_node == "default:dirt" or current_node == "default:dirt_with_grass") then -- found dirt so return return end end -- if we didnt find dirt then remove this node minetest.env:remove_node(pos) end })

It works amazingly! Big thanks =) After setting r = 2 forest looks like after logging :D

OT:
I just noticed that is my hundredth post. Time to open the champagne :)
