groups-and-containers

In Phaser 4, Groups manage logical collections for pooling, Containers build visual hierarchies with inherited transforms, and Layers control render order. Groups lack shared transforms, whereas Containers enable nested scene compositions.

To create nested transforms for UI overlays and health bars in Phaser 4, use Containers to establish visual hierarchies. Children added to a Container inherit its position, rotation, and scale for composite interfaces.

Use object pooling with Groups in Phaser 4 when managing collections of similar game objects that require frequent creation and destruction. Groups enable efficient recycling without applying a shared transform to the objects.

Yes, a Phaser 4 Container supports nesting within another Container. You can nest Containers to build complex UI structures and scene graphs, allowing children to inherit multi-level position and scale transforms.

The best way to control render order for grouped game objects in Phaser 4 is using Layers. Layers manage the render order and enable batch rendering of grouped objects independently of their logical grouping.

A Phaser 4 Group does not apply position or rotation to its children because Groups only manage logical collections and pooling. To apply shared transforms, use a Container instead for inherited visual hierarchies.
