Generic Object Pool system wrapping Unity3D's inbuilt ObjectPool which is an effective stack implementation under the hood that they optimize occasionally.
This package of code allows you to quickly setup the needed events with some quick properties to help common use cases, while enabling the ability to over-ride for special use cases.
This repo contains:
- the core scripts for review in github
- a .unitypackage you can download to load into any Unity project with a quick double click
This package was coded in Unity 2021.3.6f1 but should work for any Unity 2021.1 or later version as that was when ObjectPool was introduced.
Once you download the package, simply double click while your Unity scene is open, the package contains all needed code/prefabs and a test scene pre-setup.
On running the test scene, it will:
- Creates 20 objects and de-actives each one under >Enemies in the editor hierachy
- When you press F it will enable an object under >Enemies or create a new one under >Enemies
- When you hit G it will disable the object
Create a new class such as Bullet, code some movement logic for the bullet, then create a new class called BulletSpawner. On BulletSpawner.cs simply inherit SpawnerBase (which includes monobehavior already).
Attach the BulletSpawner to a blank gameobject in your scene hierachy, configure starting values in inspector (hover for tooltips) Then use your preference of event wiring or GetComponent methods to acquire the interface IPoolSpawner and call .Spawn().
Note: Without additions to the BulletSpawner.cs class it will spawn directly at the Transform of BulletSpawner but as you can see in the Enemey example this is extendable.
