From 8bc8dd64c56b6c5a7350fb7504864acf116f447f Mon Sep 17 00:00:00 2001 From: Wuzzy Date: Sat, 7 Mar 2015 08:32:00 +0100 Subject: [PATCH] Make TNT respect on_blast, implement on_blast for some nodes Implemented nodes: - Steel Door: Ignores explosion - Locked Chest: Ignores explosion - Fire: Ignores explosion - TNT: Starts burning - Burning TNT: Explodes immediately - Gunpowder: Starts burning - Burning Gunpowder: Ignores explosion --- mods/default/nodes.lua | 1 + mods/doors/init.lua | 39 +++++++++++++++++++++++++++++++++++---- mods/fire/init.lua | 3 +++ mods/tnt/init.lua | 37 ++++++++++++++++++++++--------------- 4 files changed, 61 insertions(+), 19 deletions(-) diff --git a/mods/default/nodes.lua b/mods/default/nodes.lua index d875531..ac7414b 100644 --- a/mods/default/nodes.lua +++ b/mods/default/nodes.lua @@ -1341,6 +1341,7 @@ minetest.register_node("default:chest_locked", { ) end end, + on_blast = function() end, }) diff --git a/mods/doors/init.lua b/mods/doors/init.lua index 7c2cf1c..74c7eec 100644 --- a/mods/doors/init.lua +++ b/mods/doors/init.lua @@ -108,6 +108,33 @@ function doors.register_door(name, def) end end + local function check_and_blast(pos, name) + local node = minetest.get_node(pos) + if node.name == name then + minetest.remove_node(pos) + end + end + + local function make_on_blast(base_name, door_type, other_door_type) + if def.only_placer_can_open then + return function() end + else + if door_type == "_b_1" or door_type == "_b_2" then + return function(pos, intensity) + check_and_blast(pos, name..door_type) + pos.y = pos.y + 1 + check_and_blast(pos, name..other_door_type) + end + elseif door_type == "_t_1" or door_type == "_t_2" then + return function(pos, intensity) + check_and_blast(pos, name..door_type) + pos.y = pos.y -
