From: PilzAdam Date: Sat, 6 Dec 2014 17:47:46 +0000 (+0100) Subject: Rewrite furnace X-Git-Tag: 0.4.11~13 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5a06de184c37e58ed8b69bc312f647f7bb6abf48;p=oweals%2Fminetest_game.git Rewrite furnace * Move furnace related code into furnace.lua * Move duplicated code into functions * Rewrite ABM: * Easier to follow strcuture (no returns in the middle) * No unnecessary calls to get_craft_result * Split logic and "visual feedback" (a bit) * Fewer calls to meta:set and meta:get * Better feedback on the current state of the furnace --- diff --git a/mods/default/furnace.lua b/mods/default/furnace.lua new file mode 100644 index 00000000..d49d8efe --- /dev/null +++
