Use Phaser.Actions.GridAlign with a config object specifying width, height, cellWidth, cellHeight, x, and y. Pass an array of game objects or group.getChildren() as the first argument, and all items are positioned into the grid in one call.

Use Phaser.Actions property setters like SetX, SetAlpha, SetScale, or the generic PropertyValueSet. Each accepts an array of objects plus an optional step parameter that adds an incremental offset per item for staggered values.

Phaser.Actions operate on plain arrays, not Group instances directly. Call group.getChildren() to obtain the array of children, then pass it to any action such as PlaceOnCircle or Spread.

Placement actions require Phaser.Geom objects, not Game Object shapes. When using a Phaser.GameObjects.Circle, pass its .geom property instead so the action receives the underlying geometry object.

GetValue supports dot-path lookups like 'render.screen.width' with fallback sources, while GetFastValue only checks top-level keys. Use GetFastValue in hot loops since it skips dot-path parsing and runs faster.

Yes, Shuffle uses the Fisher-Yates algorithm and modifies the array in place, then returns the same array. The same in-place behavior applies to Phaser.Utils.Array.Shuffle.
