This was a slight modification from my original BombSpawner script, and it is what I used for the "missile" projectiles that I had in my game. Since I realized that the game was slightly difficult with all its new features and obstacles, I changed up the script for one obstacle, making it so that once one player died, they would no longer spawn.
