hello, I have made a space shooting game. You are a Cruiser and you shoot the Pirates. I wanted to make a "pet" to help me shoot the Pirates. It follows the pirate and shoots at it, but when it's gone, an error pops up. I think it is because the pet is looking for a pirate but can't find it, which makes an error. The crazy thing is, is that when a Pirate dies, another spawns right away. Please help me fix it. Here is the "Pet's" code:
Here is the Pirate's code:
P.S. the "pet" is actually called "Cruiser2".
