creating non-cubic nodes tutorial
Posted: Tue Apr 02, 2013 14:19I haven't seen a lot of mods that have non-cubic nodes, so it seems like a lot of people don't know how to make non-cubic nodes. That's why I made this tutorial.
This assumes that you know how to add new nodes, and that you understand how to code stuff.
Example:
(This is the code for the leaves in my minitrees mod)
All nodes have to be made of one rectangular prism or multiple rectanglular prisms.
This is the part that makes the shape of it:
Each line of numbers stands for each rectangular prism in the node. The numbers in each line stand for (in this order):
{ -x, -y, -z, x, y, z }
or, more simply:
{ left side, bottom, back, right side, top, front }
They are measured from the middle of the nodebox (0), and the edge of the nodebox is 0.5 or 1/2 (one half)
If the middle of the nodebox is inside the node, then the first 3 coordinates will be negitive, and the last 3 will be positive.
Here is a picture:
You can use as many rectangular prisms as you want, but it is better to use fewer.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.
- Code: Select all
minetest.register_node('minitrees:leaves', {
description =("Mini Leaves"),
drawtype = "nodebox",
tiles = {
'leaves.png',
},
selection_box = {
type = "fixed",
fixed = { -1/3, -1/3, -1/3, 1/3, 1/3, 1/3 }
},
node_box = {
type = "fixed",
fixed = {
{ -1/3, -0.5, -1/3, 1/3, 0.5, 1/3 },
{ -0.5, -1/3, -1/3, -1/3, 1/3, 1/3 },
{ 1/3, -1/3, -1/3, 0.5, 1/3, 1/3 },
{ -1/3, -1/3, 1/3, 1/3, 1/3, 0.5 },
{ -1/3, -1/3, -0.5, 1/3, 1/3, -1/3 },
},
},
sunlight_propagates = true,
paramtype = "light",
walkable = true,
