You can do this without physics. You copy the bounds of the game objects to rectangles and then use the [Phaser.Geom.Intersects](https://photonstorm.github.io/phaser3-docs/Phaser.Geom.Intersects.html) methods. Recycling the rectangles is efficient.

Most game objects have two boundaries, possibly distinct: [Phaser.GameObjects.Components.GetBounds#getBounds()](https://photonstorm.github.io/phaser3-docs/Phaser.GameObjects.Components.GetBounds.html#getBounds) and [Phaser.Display.Bounds.GetBounds()](https://photonstorm.github.io/phaser3-docs/Phaser.Display.Bounds.html#.GetBounds). If you’re not interested in transforms then `GetBounds()` is faster.

[Phaser.Geom.Intersects.RectangleToRectangle()](https://photonstorm.github.io/phaser3-docs/Phaser.Geom.Intersects.html#.RectangleToRectangle) tells you whether the rectangles intersect at all, and [Phaser.Geom.Intersects.GetRectangleIntersection()](https://photonstorm.github.io/phaser3-docs/Phaser.Geom.Intersects.html#.GetRectangleIntersection) calculates the intersection area, if any.

@samme you are a genius man. I hope you know that. Half of my game is only functional because of some of the posts you’ve been involved in.
