....Oops
Well.
Ok.
I set it up to spawn that projectile instead, and...
Well, I quickly learned it doesn't disappear when it hits a brick with no bounce event.
Also, it flies through the air too easily, so I couldn't really stop it, so it just went back and forth, spawning more in the center, and I gave up and watched as the scoreboard had a seizure. Eventually they started moving so fast that one got completely stuck in a wall and the red score counter went up like a millisecond timer until I got "Too many events at once!" and my client crashed a few seconds later.
If I'm ever going to use that projectile, I'll have to redesign the court. It could be very good, though, from what I saw.
