Now I'm having an issue trying to actually get a game object from the pool. It is a good practice and design pattern to keep in mind to help relieve the processing power of the CPU to handle more important tasks and not become inundated by repetitive create and destroy calls.

In the extreme case, old games used to be written with all the objects "allocated" from the get-go - very little or no memory de/allocation while the game was running. Step Two: Object pooling logic: In Factory, we created a new instance of prefab, and later we destroyed it which is not an issue when we want to create just a few instances. kPooling also comes with a simple but powerful Processor API for adding pooling support for any C# type in both runtime and Editor. This way is called object pooling. Is object pooling instantiating these decals and then positioning them when I need them? In this session, we will look at a new way of handling this.

Sometimes when you make a game you need to create and destroy a lot of objects of the same type over and over again. Object Pooling allows us to reuse already instantiated objects. If there is an inactive object in the pool we set the position and the rotation, set it to be active (otherwise it could be reused by accident if you forget to activate it) and return it to the requester. Object Pooling is a great way to optimize your projects and lower the burden that is placed on the CPU when having to rapidly create and destroy GameObjects.
