is their an easier way to stop the camera from going to far not involving a cube stretched over a plain and the alpha set to zero???

What?

At the risk of appearing sarcastic ( Me?? I know, right!? ) I would like to let you know that this is not the age of the telegram. You're not charged by the word, so feel free to actually let rip with as much information as possible, because this is another question whose answer depends on information you haven't provided.

However, assuming that you want to limit your camera based on a simple cube zone ( which I'm assuming from your stretched cube comment ) then you can simply check the position boundary against your ( now imaginary ) cube boundaries.

EG:

If CameraPosX>100
   CameraPosX=100
End If
If CameraPosX<-100
   CameraPosX=-100
End If
If CameraPosY>10
   CameraPosY=10
End If
If CameraPosY<0
   CameraPosY=0
End If
If CameraPosZ>100
   CameraPosZ=100
End If
If CameraPosZ<-100
   CameraPosZ=-100
End If

Would limit you to a 200x200x10 zone around the origin.

:D Startin programming when your young, that's what I did. Started learning using the BlitzBasic around 13 or 14. Found out about Blitz3D. I'm 18 now, but a just a few years ago I finally bought Blitz3D and it's the best :D

Also a dynamic way to do what Gabriel did is, if I have the right idea of what he's doing..

If CameraPosX>MeshWidth(model)
   CameraPosX=MeshWidth(model)
End If
If CameraPosX<-MeshWidth(model)
   CameraPosX=-MeshWidth(model)
End If
If CameraPosY>10
   CameraPosY=10
End If
If CameraPosY<0
   CameraPosY=0
End If
If CameraPosZ>MeshDepth(model)
   CameraPosZ=MeshDepth(model)
End If
If CameraPosZ<-MeshDepth(model)
   CameraPosZ=-MeshDepth(model)
End If

So if you change the size of the model (the cube or whatever), then you don't have to worry about changing the stopping code :D

You can use MeshHeight for the Y axis but I'm not sure if you wanted that or not.
