Join Jesse Freeman for an in-depth discussion in this video Building an object pool, part of Unity 5: 2D Essential Training (2015).
- Now we're ready to start building out our object pool.…In essence, an object pool is simply…going to be a class that manages instances it creates.…In the case of a pool, it'll also manage…whether the objects are inactive or active,…so whenever you request a new game object from the pool,…it'll look through its list, see which ones…have been already created but are not in use,…and return one of those.…If there aren't any inactive objects,…it'll create a new one for you.…
Not all object pools dynamically scale…like the one we're about to build.…Sometimes you might want to have an object pool…that has a set number of instances…that it's allowed to create.…This way, you don't come up with situations…where you have a performance impact,…creating lots of new instances on the fly.…But to keep things simple, we're going to just make…a single object pool that will always give you…back an instance, either one that's already been created…and not in use, or a new one from scratch.…Let's go into our scripts folder…and create a new C# script,…
Super Zombie Runner riffs off the popular endless runner genre: a one-button casual game that's not only fun to play but exciting to build. The focus of the work is a reusable code base that you can extend and make your own, while learning the basics of object pooling, supporting multiple screen resolutions, tracking scoring, and multi-platform publishing. Along the way, Jesse covers key Unity features, such as working with sprites, creating animations, and leveraging the UI components.
