nice ship shoot effects

for my game i'm searching simple and original ideas for the player ship shoot. (i detect collision with ennemies via imagecollide functions).
Need some ideas !

For example :

Graphics 800,600


Global ListeCercles:TList = CreateList()

Function DrawVectorCircle(cx:Double,cy:Double,radiusx:Double, radiusy:Double)
	Local lx:Double=radiusx*Cos(0)
	Local ly:Double=radiusy*Sin(0)
	For Local d:Double=20 To 360 Step 20
	Local nx:Double = radiusx*Cos(d)
	Local ny:Double = radiusy*Sin(d)
	SetColor 0,100,0
	DrawLine(cx+lx,cy+ly-1,cx+nx,cy+ny-1)	
	SetColor 0,255,0
	DrawLine(cx+lx,cy+ly,cx+nx,cy+ny)
	SetColor 0,100,0
	DrawLine(cx+lx,cy+ly+1,cx+nx,cy+ny+1)
	
	lx=nx
	ly=ny
	Next
End Function

Type TCercle

	Field x
	Field y
	Field Rayon
	Field a#

	Function Creer:TCercle (x,y)
	
		Local n:TCercle = New TCercle
		
		n.x = x + Rand (-5,5)
		n.y = y
		n.rayon = 1
		
		ListAddLast ListeCercles, n
		
		Return n
	
	End Function
	
	Function Maj()
	
		For c:TCercle = EachIn ListeCercles
		
			SetBlend lightblend
			SetLineWidth 2
			If c.y > 0 Then
				c.y = c.y - 5
				If (c.y Mod 7) = 0 Then 
					If c.a < 10 Then
						c.a = c.a + 1
						c.Rayon = c.Rayon + c.a
					End If
				End If
				SetColor 255,0,0
				DrawVectorCircle (c.x , c.y, c.rayon, 5)
			Else
				ListeCercles.Remove c
			End If
		Next
	
	End Function

End Type

While Not KeyDown (KEY_ESCAPE)

	Cls
	If MouseDown(1)	
		l = TCercle.Creer (MouseX(), MouseY())
		FlushMouse()
	End If
	
	TCercle.Maj()
	Flip

How about shooting circles or arcs.

I also liked the precision shooting in datastorm/defender where you have a very thin shot so you have to get it dead accurate.

How about 'aftertouch' like Sensi-soccer and KickOff had. You fire your missile and then have a short amount of time to affect it's trajectory.

@tonyg : i've some guided missiles in the game ;-) i'm searching idea as laser beam. Also something easy to implement. Something with cool effects, beautiful at screen.

i've
green simple beam shoot
Remote missile shoot
green sinusoid ball shoot

@hub,
you may implement a 'firework roket' which later explodes ans spreads several shots in random directions, within a limited range.

An enhanced 'firework roket' would be a roket like above, which 'explodes' more than one time during its travel.

I would blend down the background a little though, because sometime it's hard to distinguish the aliens, expecially when they fly over the planet.

Also a spinning planet would be nice, but would hard to do without 3D module, you know..

hub, not a homing missile (i.e. fire and forget) but a missile will fly straight unless you hit right/left cursor where it's trajectory bends slightly but not too much. You can't control the flight just influence it slightly.

nice ideas ! Thanks ! i've added a simple arc style shoot and 'dual bullets'.
