Hi, I would like to know how to use the createcube() and make it a parent of other cubes.

Im trying to make a cube game with sections made of cubes to make one big cube, something like the rubiks cube.

Please Help...

Thank You.

You are probably best parenting multiple cubes to pivots as opposed to each other.

I'd suggest by making the 'Big Cube' just a pivot, since it wont actually exist as a 3D object, but just to represent all of the little cubes as a whole

Global ChildCubes[8]
Global BigCube=CreatePivot()
For n=0 to 7
ChildCubes[n]=CreateCube(BigCube)

---edit--- like Puki sugegsted 2 seconds efore me :P

Oh, that's actually pretty easy if you know how. Just create your parent cube first, then create the other cubes as children. Like this:

;Create the first parent cube
Global Cube1 = CreateCube()

;Now create the others & assign Cube1 as their parent
Global Cube2 = CreateCube(Cube1)
Global Cube3 = CreateCube(Cube1)
;... And so on. Repeat as needed.

An alternate method is to use EntityParent(), like so:

Global Cube1 = CreateCube()

Global Cube2 = CreateCube()
EntityParent Cube2,Cube1

Hope that helps!

How do I rotate all the cubes together using the pivot just like the rubiks cube?

this is what I have so far.. it only rotates that one cube..

Dim cubes(16)
P_cube = CreatePivot()
For i = 0 To 15
cubes(i)=CreateCube(P_cube)
Next

PositionEntity cubes(2),0,0,5
PositionEntity cubes(3),2.2,0,5

While Not KeyDown( 1 )
mx = MouseX()
my = MouseY()

RotateMesh cubes(1),mx,my,0

RenderWorld
Flip

to rotate the whole lot as one, just rotate the pivot :)

RotateEntity P_Cube,mx,my,0

Yes, and as Malice shows, be sure to use RotateEntity instead of RotateMesh! Else your mesh data gets deformed..

I only put RotateEntity as I didnt expect RotateMesh to work on the Pivot lol.
