There are 3 possibilities: 1) Jungle: Top part is placed on top of a jungle tree or fern (=v6 jungle grass). This is because the schematic might be placed even if some nodes of it could not be placed because the destination was already occupied. TODO: A better fix for this would be if schematics could abort placement altogether if ANY of their nodes could not be placed. 2) Cavegen: Removes the bottom part, the upper part floats 3) Mudflow: Same as 2) ]] local plants = minetest.find_nodes_in_area(minp, maxp, "group:double_plant") for n = 1, #plants do local node = vm:get_node_at(plants[n]) local is_top = minetest.get_item_group(node.name, "double_plant") == 2 if is_top then local p_pos = area:index(plants[n].x, plants[n].y-1, plants[n].z) if p_pos then node = vm:get_node_at({x=plants[n].x, y=plants[n].y-1, z=plants[n].z}) local is_bottom = minetest.get_item_group(node.name, "double_plant") == 1 if not is_bottom then p_pos = area:index(plants[n].x, plants[n].y, plants[n].z) data[p_pos] = c_air lvm_used = true end end end end end local function basic(vm, data, data2, emin, emax, area, minp, maxp, blockseed) if not (minp.y <= mcl_vars.mg_nether_max and maxp.y >= mcl_vars.mg_nether_min) then return end -- Nether block fixes: -- * Replace water with Nether lava. -- * Replace stone, sand dirt in v6 so the Nether works in v6. local nodes = minetest.find_nodes_in_area(emin, emax, {"group:water"}) for _, n in pairs(nodes) do data[area:index(n.x, n.y, n.z)] = c_nether_lava lvm_used = true end nodes = minetest.find_nodes_in_area(emin, emax, {"mcl_core:water_source", "mcl_core:stone", "mcl_core:sand", "mcl_core:dirt"}) for n=1, #nodes do local p_pos = area:index(nodes[n].x, nodes[n].y, nodes[n].z) if data[p_pos] == c_water then data[p_pos] = c_nether_lava lvm_used = true elseif data[p_pos] == c_stone then data[p_pos] = c_netherrack lvm_used = true elseif data[p_pos] == c_sand or data[p_pos] == c_dirt then data[p_pos] = c_soul_sand lvm_used = true end end end local function end_fixes(minp,maxp) if not ( minp.y <= mcl_vars.mg_end_max and maxp.y >= mcl_vars.mg_end_min ) then return end local nodes = minetest.find_nodes_in_area(emin, emax, {"mcl_core:water_source", "mcl_core:stone", "mcl_core:sand", "mcl_core:dirt"}) if #nodes > 0 then lvm_used = true for _,n in pairs(nodes) do data[area:index(n.x, n.y, n.z)] = c_air end end end local function basic_node(minp, maxp, blockseed) if mg_name ~= "singlenode" then -- Generate special decorations if mg_name == "v6" then generate_underground_mushrooms(minp, maxp, blockseed) generate_nether_decorations(minp, maxp, blockseed) end_fixes(minp,maxp) remove_mgv6_broken_plants(minp,maxp,blockseed) generate_mgv6_structures(minp, maxp, blockseed, minetest.get_mapgen_object("biomemap")) end end end mcl_mapgen_core.register_generator("mgv6-fixes", basic, basic_node, 10, true)
