well im trying to make a side scroller, but the camera won't display past the screenboarder.
Graphics 800,600,32,2
SeedRnd MilliSecs()

Global fullscreen = CreateImage(GraphicsWidth(),GraphicsHeight())
Global camerax,cameray,cameravx,cameravy,cameramove
Type dot
Field x,y
End Type
For loop = 1 To 50
dot.dot = New dot
dot\x = Rand(0,GraphicsWidth())
dot\y = Rand(0,GraphicsHeight())
Next
While Not KeyDown(1)
;draw the screen borders
Line 0,0,GraphicsWidth(),0
Line 0,0,0,GraphicsHeight()
Line GraphicsWidth()-1,0,GraphicsWidth()-1,GraphicsHeight()-1
Line 0,GraphicsHeight()-1,GraphicsWidth()-1,GraphicsHeight()-1
For dot.dot = Each dot
Plot dot\x,dot\y
Next
x = x + MouseXSpeed()
y = y + MouseYSpeed()
If y < 0 Then y = 0
If y > 600 Then y = 600
If x < 0 Then x = 0
If x > 800 Then x = 800
updatecamera(x,y)
