FOSS gamedev and creative worlds

does anyone know the exact dimensions of the default block? (in real world measurements?)

(It's 1x1x1 in blender units, so nevermind)

(I don't know what that converts to in other modeling software, but if unit size is a standard, then that's something I didn't know)

i remember reading somewhere that 1 block in minetest is 1m in size.

Each node in the standard cube form has an exact size of 1×1×1. Expressed in nodebox coordinates, the cube fills the room from -0.5 to 0.5 in all 3 dimensions. I guess this means your starter cube in Blender is also your standard Minetest cube. :-)
The length is without a “real” unit by default, as the engine does not dictate nor specify one.

However, in Minetest Game the node length is generally understood to be 1 metre. But this is semi-official and not really a strict standard, more meant as a guideline for design purposes.

Other subgames might differ, but the 1 metre guideline is a safe bet in most of the cases.

But since Mintest is an engine, subgames are of course free to pretend that a node length is whatever they want. For a subgame where you play as a small rodent, it might sense for the subgame author to specify that the node length represents 1cm. But remember, this unit stuff is all just convention; it does not come from the engine.


Oh, by the way: If you want to create an entity/object which is just a cube (of any size), you do NOT need a model, there is a simpler way for that. Please re-read lua_api.txt.

"I guess this means your starter cube in Blender is also your standard Minetest cube."

(edit, ah, not standard blender cube, but one standard blender unit! Thanks :)

"If you want to create an entity/object which is just a cube (of any size), you do NOT need a model, there is a simpler way for that"

I understand that (more or less), but I for the most part will not be making cubelike models. I only want the test model as a size reference, and as a temporary placement block when testing code which uses meshes.
