overwrite registered nodes

This is a bug that i also recognized: If you set the entity table to minetest.registered_nodes[] you cant change the fields in the table. Here is some (not very good) code to fix it:

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

local entity = {}
entity.after_place_node = (...)
for name,value in pairs(minetest.registered_nodes[nodename]) do
    entity[name] = param
end

minetest.register_node(name, entity)

That works, thanks PilzAdam! I wonder why the difference between the for loop, and assigning the whole object.

Just for reference, here is the full working code. entity.after_place_node should be called after the for loop to ensure you overwrite the default param.

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

local entity = {}
for name,value in pairs(minetest.registered_nodes["default:sapling"]) do
    entity[name] = value
end
entity.after_place_node = function(pos) print("TESTING123") end
minetest.register_node(":default:sapling", entity)

Heres a quick function (hack) based on your solution to make main code a little cleaner:

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.registered = function(case,name)
    local params = {}
    local list
    if case == "item" then list = minetest.registered_items end
    if case == "node" then list = minetest.registered_nodes end
    if case == "craftitem" then list = minetest.registered_craftitems end
    if case == "tool" then list = minetest.registered_tools end
    if case == "entity" then list = minetest.registered_entities end
    if list then
        for k,v in pairs(list[name]) do
            params[k] = v
        end
    end
    return params
end


Then use it like this:

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

local node = minetest.registered("node","default:sapling")
node.after_place_node = function(pos) print("TESTING123") end
minetest.register_node(":default:sapling", node)
