How can I avoid memory leaks and use loops carefully?

Hi. I need help with the following. If you could help me, this would be greatly appreciated.

  • Avoiding memory leaks.
  • Compressing code.
  • Using loops carefully.
  1. What do you want to achieve? Knowing how to avoid memory leaks and knowing how to use loops carefully. And also compressing code.

  2. What is the issue? I’m having low performance issues when it comes to moving parts or just having too many sitting parts in general.

  3. What solutions have you thought of so far? Checking other topics that are related to my issue, however, I’ve noticed that almost none of these topics have actually been solved and are just left abandoned and still unanswered.

If you can actually help me by explaining everything that I need to do to avoid memory leaks, how to compress code, and how to use loops carefully, I’ll be very grateful. Please give me examples too. I edited this because I realized I might have come off wrong before.
