From 23f69dfd1e8bac7469a00ecb6a1de5161f2475f8 Mon Sep 17 00:00:00 2001 From: iliekprogrammar Date: Sat, 20 Mar 2021 17:47:04 +0800 Subject: [PATCH 01/11] Core implementation of MC-like kelp drops. Highlights: * Kelp should no longer be able to survive without water (by decreasing its height) * When kelp is destroyed, each segment now drop a single kelp similar to MC. * Significantly refactor how kelp grows and dig. Possible optimizations might be included. --- mods/ITEMS/REDSTONE/mesecons_mvps/init.lua | 6 +- mods/ITEMS/mcl_ocean/kelp.lua | 270 +++++++++++++-------- 2 files changed, 169 insertions(+), 107 deletions(-) diff --git a/mods/ITEMS/REDSTONE/mesecons_mvps/init.lua b/mods/ITEMS/REDSTONE/mesecons_mvps/init.lua index 669edbcbba..8cd5ae872a 100644 --- a/mods/ITEMS/REDSTONE/mesecons_mvps/init.lua +++ b/mods/ITEMS/REDSTONE/mesecons_mvps/init.lua @@ -74,6 +74,7 @@ function mesecon.is_mvps_unsticky(node, pulldir, stack, stackid) end -- Functions to be called on mvps movement +-- See also the callback function mesecon.register_on_mvps_move(callback) mesecon.on_mvps_move[#mesecon.on_mvps_move+1] = callback end @@ -405,17 +406,20 @@ mesecon.register_mvps_unsticky("mcl_colorblocks:glazed_terracotta_brown") mesecon.register_mvps_unsticky("mcl_colorblocks:glazed_terracotta_light_blue") mesecon.register_mvps_unsticky("mcl_colorblocks:glazed_terracotta_pink") +-- Includes node heat when moving them mesecon.register_on_mvps_move(mesecon.move_hot_nodes) --- Check for falling after moving node mesecon.register_on_mvps_move(function(moved_nodes) for i = 1, #moved_nodes do local moved_node = moved_nodes[i] + -- Check for falling after moving node mesecon.on_placenode(moved_node.pos, moved_node.node) minetest.after(0, function() minetest.check_for_falling(moved_node.oldpos) minetest.check_for_falling(moved_node.pos) end) + + -- Callback for on_mvps_move stored in nodedef local node_def = minetest.registered_nodes[moved_node.node.name] if node_def and node_def.mesecon and node_def.mesecon.on_mvps_move then node_def.mesecon.on_mvps_move(moved_node.pos, moved_node.node, diff --git a/mods/ITEMS/mcl_ocean/kelp.lua b/mods/ITEMS/mcl_ocean/kelp.lua index 2e0dfe1a51..9d6c092793 100644 --- a/mods/ITEMS/mcl_ocean/kelp.lua +++ b/mods/ITEMS/mcl_ocean/kelp.lua @@ -9,29 +9,67 @@ local surfaces = { { "gravel", "mcl_core:gravel", 1 }, } -local function get_kelp_top(pos, node) -
