createcube()

This code creates a cube, but it's handle isn't stored. So the cube exists, but you can never change,
move/scale/turn or delete it. Not in a normal way that is.

box = createcube()
moveentity box,1,0,1
entitycolor box,255,100,100

box = createcube()
moveentity box,-1,0,1
entitycolor box,100,100,255

This situation is similair, the handle of the first box is discarded. In order to be able to use it,
you should keep it's handle somehow.

cam = createcamera()
cam = createcamera()

Again, the first camera's handle is disposed.

If you want multiple camera's to render to the screen, there are two things you can do. You can (1)
use CameraViewPort to choose the screen area the camera should render onto or (2) use CameraClsMode,
so the second camera doesn't clear the screen when it renders.
The camera's will render in the same order in which they are created.
So if you want to use CameraClsMode, you should use it on the second camera.

If you want to create multiple objects with the same name, use a Type.

Type tBox
	Field mesh
End Type

Graphics3D 800, 600, 0, 2


cam = CreateCamera()
MoveEntity cam, 0, 0, -15


For i = 0 To 5

	tB.tBox = New tBox
	tB\mesh = CreateCube()
	PositionEntity tB\mesh, Rnd(-5, 5), Rnd(-5, 5), 0
	EntityColor tB\mesh, Rand(255), Rand(255), Rand(255)
	
Next


Repeat

	For tB.tBox = Each tBox
		TurnEntity tB\mesh, 0, 1, 0
	Next

	RenderWorld
	Flip
	
Until KeyHit(1)

End

What you have is a pointer to the entity, not a name for it.

Its important to mention that although the handle is effectively disposed of, the entity data is not. Therefore what you've created is a memory leak - a block of allocated memory that you don't have any means of access to. This is potentially very bad.

If you want hundreds of cubes etc, store them in an array.

ok.. thanks.. other cuestion...

if i use clarworld() the entitys without handle are eliminated?

Well, try it. If it disappears, it's gone.

lol, you rught! :)
