Phaser 4 -- Game Object Components Reference

Component mixins that provide shared behavior to all Game Objects: Alpha, BlendMode, Depth, Flip, GetBounds, Lighting, Mask, Origin, ScrollFactor, Size, Texture, TextureCrop, Tint, Transform, Visible, PathFollower, RenderNodes, RenderSteps, Filters, FilterList.

Quick Start

// Every Game Object gets its component methods via mixins.
// Just call them directly on any game object:
const sprite = this.add.sprite(400, 300, 'hero');

sprite.setAlpha(0.5);                          // Alpha
sprite.setBlendMode(Phaser.BlendModes.ADD);    // BlendMode
sprite.setDepth(10);                           // Depth
sprite.setFlip(true, false);                   // Flip
sprite.setOrigin(0, 0);                        // Origin
sprite.setScrollFactor(0);                     // ScrollFactor (HUD)
sprite.setDisplaySize(64, 64);                 // Size
sprite.setTexture('hero', 'walk-1');           // Texture
sprite.setTint(0xff0000);                      // Tint
sprite.setPosition(100, 200);                  // Transform
sprite.setVisible(false);                      // Visible
sprite.setScale(2);                            // Transform
sprite.setAngle(45);                           // Transform

// Per-corner alpha (WebGL only)
sprite.setAlpha(1, 0.5, 0.5, 1);

// Crop a texture region
sprite.setCrop(0, 0, 32, 32);

// Enable WebGL filters (post-processing)
sprite.enableFilters();
sprite.filters.internal.addBlur(1, 2, 2, 1);

// Lighting (WebGL only, v4 feature)
sprite.setLighting(true);

Core Concepts

The Mixin System

Phaser uses Phaser.Class with a Mixins array to compose Game Objects from reusable component objects. Each component is a plain JS object whose properties and methods are copied onto the class prototype. This is NOT prototypal inheritance -- it is property copying at class definition time.

// How Phaser defines Sprite internally:
var Sprite = new Class({
    Extends: GameObject,
    Mixins: [
        Components.Alpha,
        Components.BlendMode,
        Components.Depth,
        Components.Flip,
        Components.GetBounds,
        Components.Lighting,
        Components.Mask,
        Components.Origin,
        Components.RenderNodes,
        Components.ScrollFactor,
        Components.Size,
        Components.TextureCrop,
        Components.Tint,
        Components.Transform,
        Components.Visible,
        SpriteRender
    ],
    initialize: function Sprite (scene, x, y, texture, frame) { /* ... */ }
});

Key Rules

Components are mixed in at class creation, not per-instance.
Most setter methods return this for chaining: sprite.setAlpha(0.5).setDepth(10).setPosition(100, 200).
Many properties use getters/setters internally (e.g., alpha, depth, visible, scale, rotation). Setting alpha = 0 or scale = 0 clears render flags, skipping rendering.
renderFlags is a bitmask: bit 0 = visible, bit 1 = alpha, bit 2 = scale, bit 3 = texture. All bits must be set for the object to render.
Alpha vs AlphaSingle: Alpha supports per-corner alpha (WebGL), AlphaSingle only supports a single global alpha. Containers use AlphaSingle.
Texture vs TextureCrop: TextureCrop extends Texture with setCrop() support. Sprites and Images use TextureCrop; some objects use plain Texture.
Filters and RenderSteps are v4-only, WebGL-only systems for post-processing.

RenderNodes, RenderSteps, Filters, FilterList (v4, WebGL only)

For RenderNodes, RenderSteps, and FilterList details, see the filters-and-postfx skill and references/REFERENCE.md.

Key points: Call enableFilters() on game objects before accessing filters. Cameras have filters by default. Use filters.internal for object-local effects and filters.external for screen-space effects.

For a full component-to-game-object matrix, see references/REFERENCE.md.

Factory Registration and Display List

Custom Game Object Factory Registration

class LaserBeam extends Phaser.GameObjects.Sprite {
    constructor(scene, x, y) {
        super(scene, x, y, 'laser');
    }
}

Phaser.GameObjects.GameObjectFactory.register('laserBeam', function (x, y) {
    const beam = new LaserBeam(this.scene, x, y);
    this.displayList.add(beam);
    return beam;
});

// Now usable in any scene:
const laser = this.add.laserBeam(100, 200);

Factory (this.add) vs Creator (this.make)

this.add creates the object AND adds it to the display list. this.make creates the object but does NOT add it -- useful for off-screen preparation or deferred display.

// Added to display list immediately
const visible = this.add.sprite(100, 100, 'hero');

// Created but NOT on the display list
const offscreen = this.make.sprite({ key: 'hero', x: 100, y: 100 });

// Add it later when ready
this.add.existing(offscreen);

GetAdvancedValue for Flexible Config

GetAdvancedValue resolves static values, random arrays, randInt/Float ranges, and callbacks from config objects:

// Static value
{ speed: 100 }

// Random from array
{ speed: [100, 200, 300] }

// Random integer range
{ speed: { randInt: [50, 150] } }

// Random float range
{ speed: { randFloat: [0.5, 1.5] } }

// Callback
{ speed: function () { return Math.random() * 100; } }

Display List Ordering

Objects added later render on top of earlier objects. Control ordering with:

// Depth-based ordering (higher = on top, triggers sort)
sprite.setDepth(10);

// Display list position (no depth change)
sprite.setToTop();
sprite.setToBack();
sprite.setAbove(otherSprite);
sprite.setBelow(otherSprite);

When both depth and display list position are used, depth takes priority after the next sort pass.

Gotchas

alpha=0 prevents rendering entirely: Setting alpha to 0 clears a render flag bit. The object is not drawn at all, not merely transparent. Same applies to scale = 0 and visible = false.
Flip does not affect physics: Flipping is rendering-only. Physics bodies remain unchanged. Account for this in collision code.
ScrollFactor and physics: Physics collisions use world position. A scroll factor other than 1 offsets where the texture renders but not where the body is. For HUD elements with scroll factor 0, avoid adding physics bodies.
depth vs display list order: setDepth() queues a sort and is the primary z-ordering tool. setToTop(), setAbove(), etc. reorder the display list without changing depth. If you mix both, depth takes priority after the next sort.
Mask component is Canvas-only in v4: For WebGL masking, use enableFilters() then filters.internal.addMask(). The setMask() method logs a warning in WebGL.
setTintFill is removed in v4: Use setTint(color).setTintMode(Phaser.TintModes.FILL) instead.
Tint modes in v4: Tint mode is now separate from tint color. Available modes: MULTIPLY (default), FILL, ADD, SCREEN, OVERLAY, HARD_LIGHT.
displayWidth/displayHeight adjusts scale: Setting displayWidth or displayHeight modifies scaleX/scaleY. It does NOT change width/height.
setSize vs setDisplaySize: setSize() changes internal dimensions (used for frames, physics). setDisplaySize() changes the rendered size by adjusting scale.
Origin default is 0.5: All Game Objects default to center origin. Use setOrigin(0, 0) for top-left positioning. Text and BitmapText instead default to top-left positioning.
Transform.z is NOT depth: The z property on Transform is for custom use. Rendering order is controlled by depth (Depth component) or display list position.
Filters are expensive: Each object with active filters requires extra draw calls. Use renderFilters = false to temporarily disable. Internal filters are cheaper than external.

Factory Registration and Display List

Custom Game Object Factory Registration

class LaserBeam extends Phaser.GameObjects.Sprite {
    constructor(scene, x, y) {
        super(scene, x, y, 'laser');
    }
}

Phaser.GameObjects.GameObjectFactory.register('laserBeam', function (x, y) {
    const beam = new LaserBeam(this.scene, x, y);
    this.displayList.add(beam);
    return beam;
});

// Now usable in any scene:
const laser = this.add.laserBeam(100, 200);

Factory (this.add) vs Creator (this.make)

this.add creates the object AND adds it to the display list. this.make creates the object but does NOT add it -- useful for off-screen preparation or deferred display.

// Added to display list immediately
const visible = this.add.sprite(100, 100, 'hero');

// Created but NOT on the display list
const offscreen = this.make.sprite({ key: 'hero', x: 100, y: 100 });

// Add it later when ready
this.add.existing(offscreen);

GetAdvancedValue for Flexible Config

GetAdvancedValue resolves static values, random arrays, randInt/Float ranges, and callbacks from config objects:

// Static value
{ speed: 100 }

// Random from array
{ speed: [100, 200, 300] }

// Random integer range
{ speed: { randInt: [50, 150] } }

// Random float range
{ speed: { randFloat: [0.5, 1.5] } }

// Callback
{ speed: function () { return Math.random() * 100; } }

Display List Ordering

Objects added later render on top of earlier objects. Control ordering with:

// Depth-based ordering (higher = on top, triggers sort)
sprite.setDepth(10);

// Display list position (no depth change)
sprite.setToTop();
sprite.setToBack();
sprite.setAbove(otherSprite);
sprite.setBelow(otherSprite);

When both depth and display list position are used, depth takes priority after the next sort pass.

Gotchas

alpha=0 prevents rendering entirely: Setting alpha to 0 clears a render flag bit. The object is not drawn at all, not merely transparent. Same applies to scale = 0 and visible = false.
Flip does not affect physics: Flipping is rendering-only. Physics bodies remain unchanged. Account for this in collision code.
ScrollFactor and physics: Physics collisions use world position. A scroll factor other than 1 offsets where the texture renders but not where the body is. For HUD elements with scroll factor 0, avoid adding physics bodies.
depth vs display list order: setDepth() queues a sort and is the primary z-ordering tool. setToTop(), setAbove(), etc. reorder the display list without changing depth. If you mix both, depth takes priority after the next sort.
Mask component is Canvas-only in v4: For WebGL masking, use enableFilters() then filters.internal.addMask(). The setMask() method logs a warning in WebGL.
setTintFill is removed in v4: Use setTint(color).setTintMode(Phaser.TintModes.FILL) instead.
Tint modes in v4: Tint mode is now separate from tint color. Available modes: MULTIPLY (default), FILL, ADD, SCREEN, OVERLAY, HARD_LIGHT.
displayWidth/displayHeight adjusts scale: Setting displayWidth or displayHeight modifies scaleX/scaleY. It does NOT change width/height.
setSize vs setDisplaySize: setSize() changes internal dimensions (used for frames, physics). setDisplaySize() changes the rendered size by adjusting scale.
Origin default is 0.5: All Game Objects default to center origin. Use setOrigin(0, 0) for top-left positioning. Text and BitmapText instead default to top-left positioning.
Transform.z is NOT depth: The z property on Transform is for custom use. Rendering order is controlled by depth (Depth component) or display list position.
Filters are expensive: Each object with active filters requires extra draw calls. Use renderFilters = false to temporarily disable. Internal filters are cheaper than external.
