IF'S from hell

I'm using a keyboard movement system, not a mouse, but here is how I do a strafe. I created a pivot for my camera, naming it "pcam". Movement operations are done to the pivot pcam, and the camera follows along for the ride.

	strafe=False:dir#=0
	If KeyDown(205)       ;turn right
		If KeyDown(56) Or KeyDown(184) ;either ALT key
			strafe=True	
			dir=0.1
		Else
			cam_y=cam_y-2
		EndIf
	Else If KeyDown(203)  ;turn left 
		If KeyDown(56) Or KeyDown(184) ;either ALT key
			strafe=True	
			dir=-0.1
		Else	
			cam_y=cam_y+2
		EndIf
	EndIf
	cam_z#=0		
	If KeyDown(200)       ;Up arrow, go forward
		If KeyDown(42) Or KeyDown(54) ;either Shift key
			cam_z = .3  ;running
		Else
			cam_z = .1
		EndIf
	Else If KeyDown(208)  ;Down arrow, go back
		If KeyDown(42) Or KeyDown(54) ;either Shift key
			cam_z = -.3 ;running
		Else
			cam_z = -.1
		EndIf
	EndIf
	If strafe
		MoveEntity pcam,dir,0,0     ;go left or right
	Else
		RotateEntity pcam,0,cam_y,0 ;turn to left or right
		MoveEntity pcam,0,0,cam_z   ;go foward or back
	EndIf
	FlushKeys
	Collisions 1,2,2,2 ;Camera collision with objects, slide from point of collision
	UpdateWorld
	RenderWorld 

As you can see, I create a "strafe" condition, and activate based on whether someone is pressing an ALT key (either one). Works like a charm.

(Hmm, upon looking at my code, it occurs to me that I never initialize "cam_y", so I'll have to fix that.)
