// 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));
Every Action in Phaser.Actions follows the same pattern:
x, y, alpha, etc.).group.getChildren().Most Set/Inc actions delegate to two core functions:
PropertyValueSet(items, key, value, step, index, direction) -- Sets items[i][key] = value + (i * step).PropertyValueInc(items, key, value, step, index, direction) -- Adds items[i][key] += value + (i * step).The step parameter adds an incremental offset per item. The index and direction parameters control iteration start point and order (1 = forward, -1 = backward).
Actions like PlaceOnCircle, PlaceOnLine, RandomRectangle, etc. accept Phaser geometry objects (Phaser.Geom.Circle, Phaser.Geom.Line, etc.), NOT Game Object shapes. If using a Phaser.GameObjects.Circle, pass its .geom property instead.
