Fog of war android
<p>Im working on a sniper game for android,and I would like to make it so the area around the players aim is black,and then the area where the player is aiming is transparent,so you can see the background,which would be a street or whatever. Im using canvas to draw my images,not gl.Example of what I mean,if its unclear - </p>
