On this page we try to give you some basic informations needed to program for minetest.
To locate a random point in a three dimensional room, you need three axis: x, y and z. X points east, Y up and Z north. There can also be negative values, where X- points west, Y- down and Z- south.
1 unit on these axis appears to a player as roughly 1 meter.
Minetest uses the word “node” instead of “block”, but it’s basically the same thing you know form games like minecraft.
Nodes or blocks are the fundamental cubic unit of a world and appears to a player as roughly 1x1x1 meters in size.
You can count nodes to get the axis values and coordinates. Full numbers without decimals are every time the center of the node/cuboid.
