From ff96c0458928c28736b90aae2a1c52ecf5d88bfb Mon Sep 17 00:00:00 2001 From: Wuzzy Date: Thu, 16 Feb 2017 00:57:35 +0100 Subject: [PATCH] Change item handling: Import VoxBox code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit VoxBox' item_drop code is much more stable and the item drop behaviour seems to be much more “natural”. But it is incompatible with builtin_item, so this mod must be disabled. Merging the builtin_item features is planned. --- mods/builtin_item/init.lua | 8 + mods/item_drop/README.txt | 16 +- mods/item_drop/init.lua | 430 ++++++++++++++++++++++++++++++++++--- 3 files changed, 410 insertions(+), 44 deletions(-) diff --git a/mods/builtin_item/init.lua b/mods/builtin_item/init.lua index 5db1de62..4b1b44ce 100644 --- a/mods/builtin_item/init.lua +++ b/mods/builtin_item/init.lua @@ -1,3 +1,9 @@ +--[==[ +NOTE: THIS MOD IS DISABLED IN MINECLONE 2! +TODO: It should be merged with item_drop. + + + minetest.register_entity(":__builtin:item", { initial_properties = { hp_max = 1, @@ -200,3 +206,5 @@ minetest.register_entity(":__builtin:item", { if minetest.setting_get("log_mods") then minetest.log("action", "[builtin_item] loaded.") end + +]==] diff --git a/mods/item_drop/README.txt b/mods/item_drop/README.txt index fe43054d..66378de8 100644 --- a/mods/item_drop/README.txt +++ b/mods/item_drop/README.txt @@ -4,21 +4,7 @@ by PilzAdam Introduction: This mod adds Minecraft like drop/pick up of items to Minetest. -How to install: -Unzip the archive an place it in minetest-base-directory/mods/minetest/ -if you have a windows client or a linux run-in-place client.
