MouseXSpeed() / MouseYSpeed() by Chroma(Posted 1+ years ago)
I miss simple pleasures like MouseXSpeed so I knocked this up. I'll be doing a few more things like this to make my life easier in BMax.

EDIT: Just realized it's all integers so I took out all the Floats.
'MouseSpeed Setup
Global MouseXSpeed:Int	'MouseXSpeed() Component
Global MouseYSpeed:Int	'MouseYSpeed() Component
Global CenterX:Int = GraphicsWidth() / 2	'Find CenterX
Global CenterY:Int = GraphicsHeight() / 2	'Find CenterY
MoveMouse CenterX,CenterY	'Move Mouse to Center of Screen

Function MouseSpeed()
	Local XM:Int = MouseX()
	Local YM:Int = MouseY()
	MouseXSpeed = XM - CenterX
	MouseYSpeed = YM - CenterY
	MoveMouse CenterX,CenterY
End Function

Here's the test code to it. Hope someone finds this useful like me.

include "MouseSpeed.bmx"

Local x:Float
Local y:Float

While Not KeyHit(KEY_ESCAPE)
Cls 

MouseSpeed()	'Call This Every Cycle

'Move a "+" around with MouseSpeed
x=x+MouseXSpeed
y=y+MouseYSpeed
DrawText "+",x,y

This didn't work so I rewrote it. I don't know what Chroma was trying to do so I took a guess, it's a + that trails the mouse around. Uses code from here.
