okay, so now that I got the side step movement out of the way, I am now trying to make it look like Bob is back stepping.. to do so, I'd need to reverse the animation.. is this possible in Blitz, or will I need to make a new animation in custom?

From Blitz3D documentation:

Animate entity[,mode][,speed#][,sequence][,transition#]
...
speed# - a negative speed will play the animation backwards.

I must be doing the code all wrong then... =P

Graphics3D 640,480,16,2
SetBuffer BackBuffer()

AntiAlias enable

;----------
;load objects

camera=CreateCamera()
RotateEntity camera,45,0,0

light=CreateLight()
RotateEntity light,90,0,0

bob=LoadMD2( "bob.md2" )
RotateEntity bob,0,90,0
PositionEntity bob,0,-100,150

While Not KeyDown( 1 ) 

;----------
;movement

      If KeyDown(200) Then
          MoveEntity bob,1,0,0 
      EndIf

      If KeyDown(208) Then
          MoveEntity bob,-1,0,0
      EndIf

      If KeyDown(203) Then
          TurnEntity bob,0,1.0,0
      EndIf

      If KeyDown(205) Then
          TurnEntity bob,0,-1.0,0
      EndIf

;----------
;animation (!!!!!!!!!!)

If Not KeyDown(200) Then
	AnimateMD2 bob,1,0.1,9,1
EndIf

If Not KeyDown(208) Then
	AnimateMD2 bob,1,-0.1,9,1
EndIf 

;----------
;End Code

If bob=0 Then 
RuntimeError "Failed to load bob!"
EndIf 

UpdateWorld
RenderWorld
Flip
 
Wend

End

I dont understand why you write:

If Not KeyDown(200) Then
	AnimateMD2 bob,1,0.1,9,1

Try this instead:

;----------
;animation (!!!!!!!!!!)

If KeyDown(200)=0 And KeyDown(208)=0 Then AnimateMD2 bob,0

If KeyHit(200) Then
	AnimateMD2 bob,1,0.1,1,9
EndIf

If KeyHit(208) Then
	AnimateMD2 bob,1,-0.1,1,9
EndIf 

;----------
;End Code

Understand that you have to use AnimateMD2 once to start or stop an animation, and if no key is pressed, stop it. If you call it every loop it will not work.
