I haven't used blitz for some time but have started working on a really basic first person shooter. I have a sprite which displayes briefly when the mouse button is pressed for a muzzleflash. it works "okay" but I need to sort out the timing issues. what happens is when i press the button the sprite momentarily displays and it looks okay except with repeated presses the sprite isn't always shown, I suspect it hasn't finished the last "loop" before I press the button again . The bullet count decreases fine but i don't get a "flash" with every press. It's pretty consistent but not perfect. Any ideas on the best way to do this. I have posted in the past on similar topics but being more critical I can see it is not perfect.

Like this?

Graphics3D 800,600,32,2

Local Flash = CreateTexture(64,64)
Local FlashAlpha# = 0.0
Local FlashSpeed# = .4

;Draw flash testure
SetBuffer TextureBuffer(Flash)
Local r
For r = 0 To 16 
	Local c# =(r/16.0*255)
	Color c,c,c
	Oval r,r,64-r*2,64-r*2,1
Next

SetBuffer BackBuffer()

;Create flasher sprite
Local Flasher = CreateSprite()
EntityTexture Flasher,Flash
EntityFX Flasher,1

Local camera = CreateCamera()
MoveEntity camera,0,0,-5

Local light = CreateLight()
PositionEntity light,0,20,0

Local cube = CreateCube()
PositionEntity cube,0,0,5
EntityColor cube,100,0,0

While Not KeyHit(1)
	Cls
	TurnEntity cube,.1,.1,.1
	;Update the flash
	If FlashAlpha > 0 Then FlashAlpha = FlashAlpha - FlashSpeed
	If MouseHit(1) Then FlashAlpha = 1
	EntityAlpha Flasher,FlashAlpha
	
	;Draw world
	RenderWorld()
	Flip

Thanks, this could be exactly what I need. Just a bit of tweaking to get it into my code.
