RE:Shoot multiple times

If you want to keep track of several things of the same type, you should look into arrays and records. Here's the Turing Walkthrough links:

RE:Shoot multiple times

What do you mean? How does this help shooting multiple times?

RE:Shoot multiple times

-----------------------------------

Right now you have only bullety. You want bullety_1, bullety_2, ..., etc. An array will let you group those related variables together, for much easier use.

Thanks tony, I just looked at arrays but I'm having trouble applying it to my program
