Eg. if you have this constant somewhere that you just can't get right by changing it and recompiling all over again: v3f wield_position = v3f(55, -35, 65); Make it look like this: v3f wield_position = v3f(55, -35, 65); QUICKTUNE_AUTONAME(QVT_FLOAT, wield_position.X, 0, 100); QUICKTUNE_AUTONAME(QVT_FLOAT, wield_position.Y, -80, 20); QUICKTUNE_AUTONAME(QVT_FLOAT, wield_position.Z, 0, 100); Then you can modify the values at runtime, using the keys keymap_quicktune_prev keymap_quicktune_next keymap_quicktune_dec keymap_quicktune_inc Once you have modified the values at runtime and then quit, the game will print out all the modified values at the end: Modified quicktune values: wield_position.X = 60 wield_position.Y = -30 wield_position.Z = 65 The QUICKTUNE macros shouldn't generally be left in committed code. */ #ifndef QUICKTUNE_HEADER #define QUICKTUNE_HEADER #include <string> #include <map> #include <vector> enum QuicktuneValueType{ QVT_NONE, QVT_FLOAT }; struct QuicktuneValue { QuicktuneValueType type; union{ struct{-- Minetest: builtin/item.lua -- -- Falling stuff -- minetest.register_entity("__builtin:falling_node", { initial_properties = { physical = true, collide_with_objects = false, collisionbox = {-0.5,-0.5,-0.5, 0.5,0.5,0.5}, visual = "wielditem", textures = {}, visual_size = {x=0.667, y=0.667}, }, node = {}, set_node = function(self, node) self.node = node local stack = ItemStack(node.name) local itemtable = stack:to_table() local itemname = nil if itemtable then itemname = stack:to_table().name end local item_texture = nil local item_type = "" if minetest.registered_items[itemname] then item_texture = minetest.registered_items[itemname].inventory_image item_type = minetest.registered_items[itemname].type ass="hl opt">} self.object:set_properties(prop) end, get_staticdata = function(self) return self.node.name end, on_activate = function(self, staticdata) self.object:set_armor_groups({immortal=1}) --self.object:setacceleration({x=0, y=-10, z=0}) self:set_node({name=staticdata}) end, on_step = function(self, dtime) -- Set gravity self.object:setacceleration({x=0, y=-10, z=0}) -- Turn to actual sand when collides to ground or just move local pos = self.object:getpos() local bcp = {x=pos.x, y=pos.y-0.7, z=pos.z} -- Position of bottom center point local bcn = minetest.get_node(bcp) -- Note: walkable is in the node definition, not in item groups if minetest.registered_nodes[bcn.name] and minetest.registered_nodes[bcn.name].walkable or (minetest.get_node_group(self.node.name, "float") ~= 0 and minetest.registered_nodes[bcn.name].liquidtype ~= "none") then if minetest.registered_nodes[bcn.name].leveled and bcn.name == self.node.name then local addlevel = self.node.level if addlevel == nil or addlevel <= 0 then addlevel = minetest.registered_nodes[bcn.name].leveled end if minetest.env:add_node_level(bcp, addlevel) == 0 then self.object:remove() return end elseif minetest.registered_nodes[bcn.name].buildable_to and (minetest.get_node_group(self.node.name, "float") == 0 or minetest.registered_nodes[bcn.name].liquidtype == "none") then minetest.remove_node(bcp) return end local np = {x=bcp.x, y=bcp.y+1, z=bcp.z} -- Check what's here local n2 = minetest.get_node(np) -- If it's not air or liquid, remove node and replace it with -- it's drops if n2.name ~= "air" and (not minetest.registered_nodes[n2.name] or minetest.registered_nodes[n2.name].liquidtype == "none") then local drops = minetest.get_node_drops(n2.name, "") minetest.remove_node(np) -- Add dropped items local _, dropped_item for _, dropped_item in ipairs(drops) do minetest.add_item(np, dropped_item) end -- Run script hook local _, callback for _, callback in ipairs(minetest.registered_on_dignodes) do callback(np, n2, nil) end end -- Create node and remove entity minetest.add_node(np, self.node) self.object:remove() nodeupdate(np) else -- Do nothing end end }) function spawn_falling_node(p, node) obj = minetest.add_entity(p, "__builtin:falling_node") obj:get_luaentity():set_node(node) end function drop_attached_node(p) local nn = minetest.get_node(p).name minetest.remove_node(p) for _,item in ipairs(minetest.get_node_drops(nn, "")) do local pos = { x = p.x + math.random()/2 -
