'Leveled' nodebox type used anywhere?

[Termos]

Does anyone know of any mod or subgame that uses node_box.type = 'leveled'?
I need to test my pathfinding algorithm with an actual implementation of this.

The "Snow Biomes" mod uses levelled nodes to have different height snowblocks on the ground which can pile up when the snow is falling or placed by player: viewtopic.php?t=2290

Thanks! This will do nicely.

I've also added leveled nodeboxes very recently for the hay generated in my cottages mod.

Leveled nodes seem to have a strange and intresting effect. When I was experimenting with them, I added a small function that let each punch to the node increase its level metadata by one. After some standing on the node and happily punching, I noticed that my character moved upwards.

This makes for an entertaining - but very slow - lift:

Code: Select all

minetest.register_node("leveled:lift", {
        drawtype = "nodebox",
        paramtype2 = "leveled",
        description = "lift",
        tiles = {"default_stone.png"},
        groups = {cracky=3,snappy=3,choppy=3,oddly_breakable_by_hand=3,flammable=3},
        is_ground_content = false,
        node_box = {
                type = "leveled", --"fixed",
                fixed = {
                                {-0.5,-0.5,-0.5, 0.5, 0.5, 0.5},
                        }
        },      
        after_place_node = function(pos, placer, itemstack, pointed_thing)
                local timer = minetest.get_node_timer(pos)
                if not timer:is_started() then
                        timer:start(1)
                end
        end,
        on_punch = function(pos, node, puncher, pointed_thing)
                local node = minetest.get_node(pos)
                minetest.swap_node(pos, {name=node.name, param2=(node.param2+1)})
        end,    
        on_timer = function(pos, elapsed)      
                local node = minetest.get_node(pos)
                if( node.param2 > 64 ) then
                        minetest.swap_node( pos, {name="default:glass"})
                        pos.y = pos.y + 1
                        minetest.set_node(pos, {name=node.name, param2=0})
                else
                        minetest.swap_node(pos, {name=node.name, param2=(node.param2+2)})
                end
                local timer = minetest.get_node_timer(pos)
                if not timer:is_started() then
                        timer:start(1)
                end
        end,
})

This may be a more general issue, I noticed my mobs when walking on nodes adjacent to nodes with snow on top of them sometimes do small jumps for no reason, even though in MTG snow is fixed rather than leveled. Strange that this doesn't occur near slabs which are very similar nodedef.

Why swap nodes instead of calling add_node_level?

I wasn't aware of that function.
