This is a simple pool for optimizing object loading.

Permanent creation and destruction of objects in your scene, very expensive in terms of memory management, use the Simple Pool object pool to save memory and improve performance.

All objects in the pool are loaded during initialization, and then retrieved from the pool and returned back to the pool without sacrificing performance.

The pool allows you to completely abandon Instantiate and Destroy after initialization.
