Bug: v8.0.0-rc.4 Culler does not work? about pixijs

[davidye]

Was able to fix 1 and 2 above with this:

import { Bounds, Container, getGlobalBounds } from "pixi.js";

const tempBounds = new Bounds();

export const cull = (
  container: Container,
  view: { x: number; y: number; width: number; height: number },
  skipUpdateTransform = true,
) => {
  _cullRecursive(container, view, skipUpdateTransform);
};

const _cullRecursive = (
  container: Container,
  view: { x: number; y: number; width: number; height: number },
  skipUpdateTransform = true,
) => {
  if (container.cullable) {
    container.visible = true;

    const bounds =
      container.cullArea ??
      getGlobalBounds(container, skipUpdateTransform, tempBounds);

    // check view intersection..
    container.visible = !(
      bounds.x >= view.x + view.width ||
      bounds.y >= view.y + view.height ||
      bounds.x + bounds.width <= view.x ||
      bounds.y + bounds.height <= view.y
    );
  }

  for (let i = 0; i < container.children.length; i++) {
    _cullRecursive(container.children[i], view, skipUpdateTransform);
  }
};
