# Phaser 4 -- Actions & Utility Functions > Phaser.Actions namespace for batch operations on Game Object arrays, plus Phaser.Utils.Array, Phaser.Utils.Objects, and Phaser.Utils.String helper functions. **Related skills:** ../groups-and-containers/SKILL.md, ../sprites-and-images/SKILL.md --- ## Quick Start ```js // Create 20 sprites and batch-position them in a grid const sprites = []; for (let i = 0; i < 20; i++) { sprites.push(this.add.sprite(0, 0, 'gem')); } // Arrange into a 5x4 grid Phaser.Actions.GridAlign(sprites, { width: 5, height: 4, cellWidth: 64, cellHeight: 64, x: 100, y: 100 }); // Fade alpha from 0 to 1 across all sprites Phaser.Actions.Spread(sprites, 'alpha', 0, 1); // Offset each sprite's x by 10, with a step of 2 per item Phaser.Actions.IncX(sprites, 10, 2); // Works with Groups too const group = this.add.group({ key: 'star', repeat: 11 }); Phaser.Actions.PlaceOnCircle(group.getChildren(), new Phaser.Geom.Circle(400, 300, 200)); ``` --- ## Core Concepts ### The Actions Pattern Every Action in `Phaser.Actions` follows the same pattern: 1. **First argument is always an array** of Game Objects (or any objects with the required public properties like `x`, `y`, `alpha`, etc.). 2. **Returns the same array**, enabling chaining or pass-through. 3. **Works with Groups** by passing `group.getChildren()`. 4. Actions do NOT store state. They are one-shot batch operations. ### PropertyValueSet and PropertyValueInc Most Set/Inc ...
