GIA_Green_Fire_

What I was thinking BP_ClampValue(Value#,-2,2) would do, would be a shorter version of doing this

If Value < -2 Then Value = -2
If Value > 2 Then Value = 2

But it didn't do that. It didn't do anything. Here's what I tried.

Graphics3D 800,600,0,2
SetBuffer BackBuffer()

Global Light = CreateLight()
	
	
Global Camera = CreateCamera()
	PositionEntity Camera,0,2,-5
	RotateEntity Camera,10,0,0
	
Global Cube = CreateCube()
	EntityColor Cube,127,127,0
	EntityShininess Cube,.5
	
Global Clamp# = 0

While Not KeyDown(1)

	Clamp = Clamp + (KeyHit(200)-KeyHit(208))
	
	BP_ClampValue(Clamp,-2,2)
	
	PositionEntity Cube,0,Clamp,0
	
	UpdateWorld
	RenderWorld
	
	Text 0,0,Clamp
	
	Flip
	
Wend
End

Heh, do I have the wrong idea of what this function is supposed to do?
