How to make a transparent block like leaves with images on 2 sides?

by Neuromancer » Sat Sep 14, 2013 13:11

I'm trying to make a block that looks like leaves(you can see through empty spaces) but only has images on 2 sides of the block.

The problem with my first attempt below is that it allows you to see through the ground when placing the node.
minetest.register_node("bushes:BushQuarterBranches", {
description = "BushQuarterBranches",
tiles = {
"blank.png",
"blank.png",
"BlockBranch1Lsm.png",
"BlockBranch1Rsm.png",
"blank.png",
"blank.png",},
inventory_image = "BlockBranch1Lsm.png",
is_ground_content = true,
paramtype = "light",
paramtype2 = "facedir",
groups = {cracky=3},
sounds = default.node_sound_stone_defaults(),
})


The problem with this block is that all the images are invisible, (good news is you can't see through the ground)
minetest.register_node("bushes:BushQuarterBranches2", {
description = "BushQuarterBranches2",
drawtype = "allfaces_optional",
tiles = {
"blank.png",
"blank.png",
"BlockBranch1Lsm.png",
"BlockBranch1Rsm.png",
"blank.png",
"blank.png",},
paramtype = "light",
groups = {snappy=3, flammable=2, leaves=1},
sounds = default.node_sound_leaves_defaults(),
})

What can I do so I can see my images on 2 sides without seeing through the ground?

Here's the whole very-simple mod if it helps (just registers 3 nodes and some textures)

How about something like this

Code: Select all
minetest.register_node("bushes:BushQuarterBranches2", {
    description = "BushQuarterBranches2",
    drawtype = "nodebox",
    tiles = {
        "blank.png",
        "blank.png",
        "BlockBranch1Lsm.png",
        "BlockBranch1Rsm.png",
        "blank.png",
        "blank.png"
    },
    node_box = {
        type = "fixed",
        fixed = {
            {-1/2, -1/2, -1/2, -1/2, 1/2, 1/2},
            {1/2, -1/2, -1/2, 1/2, 1/2, 1/2}
        },
    },
    selection_box = {
        type = "fixed",
        fixed = {-1/2, -1/2, -1/2, 1/2, 1/2, 1/2},
    },
    inventory_image = "BlockBranch1Rsm.png",
    paramtype = "light",
    groups = {tree=1, snappy=3, flammable=2, leaves=1},
    sounds = default.node_sound_leaves_defaults(),
})

The panes are two-sided, but maybe it's even cooler like that.

I gave it a try. All sides still invisible. It gave me an idea to use signlike and just have 1 image per node, but the image shows up only on top of the block when I do this

minetest.register_node("bushes:BushQuarterBranches3", {
description = "BushQuarterBranches3",
drawtype = "signlike",
tile_images = {
"BlockBranch1Rsm.png" },
inventory_image = "BlockBranch1Lsm.png",
paramtype = "light",
groups = {snappy=3, flammable=2, leaves=1},
sounds = default.node_sound_leaves_defaults(),
})

And all sides invisible when I do this:
minetest.register_node("bushes:BushQuarterBranches2", {
description = "BushQuarterBranches2",
drawtype = "signlike",
tile_images = {
"blank.png",
"BlockBranch1Rsm.png",
"BlockBranch1Lsm.png",
"BlockBranch1Rsm.png",
"BlockBranch1Lsm.png",
"BlockBranch1Rsm.png",},
inventory_image = "BlockBranch1Lsm.png",
paramtype = "light",
groups = {snappy=3, flammable=2, leaves=1},
sounds = default.node_sound_leaves_defaults(),
})

That's better, but don't nodeboxes hurt performance? I'm hoping I can get signlike to work, then place 4 blocks so the branches radiate outward in 4 directions, If I could just get it to stop displaying the image on the top of the block and instead do it on the side.

Complex nodeboxes hurt performance. I'm not sure about something as simple as this.

Is there any way to get them at a right angle to each other instead of parallel?

If you mean a "+" shape (seen from above):

Code: Select all
    node_box = {
        type = "fixed",
        fixed = {
--       {left,bottom,front,right,top,back}
            {0, -1/2, -1/2, 0, 1/2, 1/2},
            {-1/2, -1/2, 0, 1/2, 1/2, 0}
        },
    },

look, for example in defautl mod, for glass, it is used:
Code: Select all
minetest.register_node("default:glass", {
    description = "Glass",
    drawtype = "glasslike",
    tiles = {"default_glass.png"},
    inventory_image = minetest.inventorycube("default_glass.png"),
    paramtype = "light",
    sunlight_propagates = true,
    groups = {cracky=3,oddly_breakable_by_hand=3},
    sounds = default.node_sound_glass_defaults(),
})


You should have those 2 tiles and 1 png transparent image.
and replace this:
Code: Select all
tiles = {"default_glass.png"},

With the tiles name(those 2 with the png image, and 4 with the transparent image)
