From: Zefram Date: Thu, 3 Jul 2014 18:42:29 +0000 (+0100) Subject: Handheld prospecting tool X-Git-Url: http://81.2.79.47:8989/gitweb/?a=commitdiff_plain;h=636b0f20df4fef3eef821c23ccc2f606828f5c6f;p=zefram%2Fminetest%2Ftechnic.git Handheld prospecting tool The new tool will say whether a target block type is present in a specified region, to allow for more targeted digging. It is deliberately quite weak, with several limitations: only stores enough charge for a small number of shots; target can only be set by pointing at an example node; range is limited; accuracy is less than 100%. Some of these limitations should probably be ameliorated, but not entirely eliminated, in the future when we have a better idea of game balance. The inventory image is only a placeholder. --- diff --git a/technic/sounds/technic_prospector_hit.ogg b/technic/sounds/technic_prospector_hit.ogg new file mode 100644 index 0000000..3a8ad2d Binary files /dev/null and b/technic/sounds/technic_prospector_hit.ogg differ diff --git a/technic/sounds/technic_prospector_miss.ogg b/technic/sounds/technic_prospector_miss.ogg new file mode 100644 index 0000000..0f050d0 Binary files /dev/null and b/technic/sounds/technic_prospector_miss.ogg differ diff --git a/technic/textures/technic_prospector.png b/technic/textures/technic_prospector.png new file mode 100644 index 0000000..2f9ee6c Binary files /dev/null and b/technic/textures/technic_prospector.png differ diff --git a/technic/tools/init.lua b/technic/tools/init.lua index 60327a5..b8d9127 100644 --- a/technic/tools/init.lua +++ b/technic/tools/init.lua @@ -13,6 +13,7 @@ dofile(path.."/cans.lua") dofile(path.."/chainsaw.lua") dofile(path.."/tree_tap.lua") dofile(path.."/sonic_screwdriver.lua") +dofile(path.."/prospector.lua") if minetest.get_modpath("screwdriver") then -- compatibility alias diff --git a/technic/tools/prospector.lua b/technic/tools/prospector.lua new file mode 100644 index 0000000..686e0a7 --- /dev/null +++ b/technic/tools/prospector.lua @@ -0,0 +1,126 @@ +local S = technic.getter + +technic.register_power_tool("technic:prospector", 15000) + +local function get_metadata(toolstack) + local m = minetest.deserialize(toolstack:get_metadata()) + if not m then m = {} end + if not m.charge then m.charge = 0 end + if not m.target then m.target = "" end + if not m.look_depth then m.look_depth = 7 end + if not m.look_radius then m.look_radius = 1 end + return m +end + +minetest.register_tool("technic:prospector", { + description = S("Prospector"), + inventory_image = "technic_prospector.png", + wear_represents = "technic_RE_charge", + on_refill = technic.refill_RE_charge, + on_use = function(toolstack, user, pointed_thing) + if not user or not user:is_player() or user.is_fake_player then return end + if pointed_thing.type ~= "node" then return end + local toolmeta = get_metadata(toolstack) + local look_diameter = toolmeta.look_radius * 2 + 1 + local charge_to_take = toolmeta.look_depth * (toolmeta.look_depth + 1) * look_diameter * look_diameter + if toolmeta.charge < charge_to_take then return end + if toolmeta.target == "" then + minetest.chat_send_player(user:get_player_name(), "Right-click to set target block type") + return + end + toolmeta.charge = toolmeta.charge -
