Ignoring collisions with clones

So I have this FPS game, and my character fires. I made the bullet so that when it collides with something, it destroys itself. So here’s the problem: my bullets are instantiated continuosly, and since that happens, they collide with each other, and end up destroying themselves. So, I want to know how to ignore collisions between these clones. Every clone that is created is named “Bullet(Clone)”. Thanks!

Simple- put all the bullets on a ‘Bullet’ layer, and then stop the bullet layer from colliding with itself! It shouldn’t be a problem unless shooting other people’s bullets out of the air is a big deal for you (in which case you can make those ‘enemy bullets’ instead).

can anyone update this? the link is also obsolete
