I finished creating the weapon marker handler and the canon-weapon. The weapon marker handler will create a marker on the spot where you click with your mouse and will send the closest idle weapon to that spot to fire.
The canon weapon will fire a bullet that will explode in a kind of shockwave.
In the working sample you can press the + (plus) key on the numeric keypad to add an additional canon weapon.

I created the canon weapon marker with Illustrator.
I created the shockwave animation (32 frames) using blender.
( everyone may use this sprite sheet 
)
The glowing marker cursor was created at runtime by creating a 15 frames long animation with the glow effect.
// generate glow bitmaps
for (var i:int=0; i<16; i++)
{
bitmap.filters = [ new GlowFilter(0x99ff00,(0+(100/25)*i)/100,6,6,4,3) ];
var bitmapData:BitmapData = new BitmapData(bitmap.width, bitmap.height,true,0);
bitmapData.draw(bitmap);
frames[frames.length] = bitmapData;
}
See this tutorial how one can render SpriteSheet animations at run time.
Next will be some dangerous space lava rocks to shoot at
