Universal node ownership

each node placed records its owner. Blocks placed by the servers' mapgen, or mods, are diggable. Nodes w/ owners can be removed using worldedit or multinode, or whatever tool mod that removes nodes instead of digging them.
Theres nothing to download, since your placing and replacing snippets of code in builtin/misc_register.lua and default/init.lua

Interesting. What are you playing with ?

add this in builtin.lua, add this line (just under misc_register):

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: dofile(minetest.get_modpath("__builtin").."/my_file.lua")

Then you can add the rest into a file of its own:

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 function is_node_owner(meta, player) if meta:get_string("owner") ~= player:get_player_name() and meta:get_string("owner") ~= '' then return false end return true end local can_dig = function(pos,player) meta = minetest.env:get_meta(pos) return is_node_owner(meta, player) end -- copy minetest.register_node to another function so we can still call it minetest_register_node = minetest.register_node; -- overwrite minetest.register_node function minetest.register_node(name, nodedef) if not nodedef.can_dig then nodedef.can_dig = can_dig end minetest_register_node(name, nodedef) -- call the real minetest.register_node end minetest.register_on_placenode(function(p, node, placer) local meta = minetest.env:get_meta(p) local player = placer:get_player_name() meta:set_string("owner",player) end)

p.s. awesome mod! very small but very useful

Well its not perfect (no antigriefing solution is 100%) - this one doesn't use zones so there's no hassle in setting them up, but if someone decides to strategically place nodes to block pathways and such, then it could be hassle having to remove them with wolrdedit or multinode (but by then youll probably ban the person for doing such, so at least they were never able to destroy any buildings)

I dont know how pertinent this mod is going to be once c55 is done implementing rollback. (saw a few references to it in the code). Im already not crazy about rollback, yesterday id find myself placing 20-30 nodes, then they'd all disappear, and come back again (wtf? lol)

That is called ''node prediction'' or something, when you place a node, Minetest predicts the node's position/collision box. Sometimes the server sends back the data for that area, before it gets the data that you changed the area, and the nodes will ''disappear'', until the server processes the data and sends the packet(s) with the data of the area back to the client. It has nothing to do with rollback.
