Description

First create a static group, and add a lot of PointLight, and then calling 'body.reset', the time consumed is increasing as the number of calls increases. I don't know if this is the correct usage!

Example Test Code

create(){
      const group = this.physics.add.staticGroup();

      for (let i = 0; i < 20; i++) {
         for (let j = 0; j < 20; j++) {
            const p = new PointLight(this, i * 40 + 100, j * 40 + 100, 0xff0000, 20, Math.random())
               .addToDisplayList();
            group.add(p);
         }
      }

    const pl = new PointLight(this, 20, 20, 0xff0000, 20, 1)
         .addToDisplayList();
    group.add(pl);

    // Test
    setInterval(() => {
       console.time('body.reset');
       // this.pl.body.enable = false;
       // this.pl.body.enable = true;
       pl.body.reset(30, 30);
       console.timeEnd('body.reset');
    }, 1000);
}

Additional Information

Long story, but the ultimate problem is that StaticBody#reset() calls PointLight#getTopLeft(), which spoils the StaticBody#position values.

I think the GetBounds component needs to be removed from PointLight, since the methods will fail.

You can probably work around this by resetting the body manually — remove from static tree, modify position, insert in static tree. But you will have to figure out the offset between the body position (top-left) and light position (center).

Yes, I also found that the old body has not been removed from the static tree. I temporarily replaced it with other methods, thank you for your suggestion @samme
