actually I want to make a shooter game , and I want to draw black circle for the sign of the bullet on the wall , I usually create transparent plane with texture and put it on the wall , but when I shoot quickly the game become very slowly specialy when the player move and when I stop shooting the game come back to the normal speed,
so I want to change my way to another one , and I found that drawing black circle is the best way . the code you put it to me was very good but I didn't know how could I use it specialy the code work with X and Y and I need Z too
that is my probelm ,is there any thing can help me or another idea to make the sign of the bullet
