@pixi-essentials/object-pool


This package implements a custom-tailored object pool for PixiJS applications. It provides the
following features:

* reserve: You can preallocate the pool size to have a set amount of objects.

* limit: You can reduce the pool size after a lot of allocations.

* auto-GC: The GC will reduce your pool to the reserve size after allocation demand goes down
per-frame.

This package can also be used as a _single-source_ of object pools. If two different libraries need
a pool for say, PIXI.Rectangle, then the same object pool will be returned.

* https://codepen.io/sukantpal/pen/zYvBOVw: This chart shows the pool capacity and the allocations done per frame. The GC
is enabled and reserve is set to 100,000.

* You should use auto-GC only if allocations-per-frame is smooth (slowly increase & slowly decrease) or you know the upper
limit of objects you need per frame.

Installation :package:

``bash
npm install @pixi-essentials/object-pool
`

Usage :page_facing_up:

`ts
import { ObjectPoolFactory } from '@pixi-essentials/object-pool';
import { Rectangle } from '@pixi/math';

const rpool: ObjectPoolFactory = ObjectPoolFactory.build(Rectangle);

rpool.reserve(10000);
rpool.startGC();// prevent pool from staying above 10,000 rectangles for too long

const rect: PIXI.Rectangle = rpool.allocate();

// do something

rpool.release(rect);

// Want to reduce pool size now?
rpool.limit(11000);
