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

something like this:

-- Minetest Die Hard Mod

math.randomseed(os.time())

local ITEM_LOSE_DICE = 4

minetest.register_on_dieplayer(function(player)
    local inv=player:get_inventory()
    if not inv:is_empty("main") then
        for i=1,inv:get_size("main") do
            if math.random(1, ITEM_LOSE_DICE) ~= 1 and not inv:get_stack("main", i):is_empty() then
                local stack = inv:get_stack("main", i)
                inv:remove_item("main", stack)
            end
        end
    end
    return
end)
