Dogfights Camera Shake

I'm trying to recreate the camera shake from the show Dogfights. When they do a fly-by shot, as soon as the aircraft passes the camera, the camera shakes. I'd like to use Millisecs() for this but I'm open to all options.

If KeyHit(57)
	shaking = True
	shake_strength# = 2.0
EndIf

If shake < 0
	shaking = False
        shake_strength = 0
EndIf

If shaking = True
	TurnEntity camera,Sin(MilliSecs() Mod 360) * shake_strength,Cos(MilliSecs() Mod 360) * shake_strength,0
	shake_strength = shake_strength - .9 * dt
EndIf

I need it to be more random (not circular) and slowly return to a steady state.

Here is my solution: (How to implantate this as code?)

; Shaking camera
; ------------------

Graphics3D 640,480
SetBuffer BackBuffer()

camera=CreateCamera()

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

; Create cone
cone=CreateCone()

PositionEntity cone,0,0,5

While Not KeyDown( 1 )

If KeyHit(57)
shaking = True
shake_strength# = 2.0
EndIf

shake_strength=shake_strength-0.02 ;Slowly remove the shaking strength
If shake_strength<0 shake_strength=0

If shake < 0
shaking = False
shake_strength = 0
EndIf

If shaking = True
TurnEntity camera,Sin(MilliSecs() Mod Rnd(350,360)) * shake_strength,Cos(MilliSecs() Mod Rnd(350,360)) * shake_strength,0 ; Use "rnd" to make the shaking more randomly
shake_strength = shake_strength - .9 * dt
EndIf

RenderWorld
Flip
Wend

End

I hope this is, what you wanted?

Wow...very choppy. I'm looking for something random but very smooth.

Chroma,

Try supercam function from the code archives, and send it rnd parameters every 5 loops or something like that.

Supercam makes the camera fluidly move from where it is to where its going based on a camera and an object to 'follow'. It may do the job if you just move the object to follow around randomly!
