PixiJS's federated event system mirrors DOM events on the scene graph. Set `container.eventMode = 'static'` to opt an object in, then listen with `.on()`, `addEventListener()`, or `onEventName` property handlers. Move events fire only over the listening object; use `globalpointermove` for drag.
Quick Start
const button = new Sprite(await Assets.load("button.png"));
button.eventMode = "static";
button.cursor = "pointer";
app.stage.addChild(button);
button.on("pointertap", (event) => {
console.log("clicked at", event.global.x, event.global.y);
});
let dragging = false;
button.on("pointerdown", () => {
dragging = true;
});
button.on("pointerup", () => {
dragging = false;
});
button.on("pointerupoutside", () => {
dragging = false;
});
button.on("globalpointermove", (event) => {
if (dragging) button.parent.toLocal(event.global, undefined, button.position);
});**Related skills:** `pixijs-accessibility` (screen reader + keyboard), `pixijs-scene-dom-container` (HTML overlays), `pixijs-performance` (event-heavy scenes).
Core Patterns
eventMode values
import { Sprite } from "pixi.js";
const sprite = new Sprite();
// No interaction at all; children also ignored
sprite.eventMode = "none";
// Default. Self not interactive; interactive children still work
sprite.eventMode = "passive";
// Hit tested only when a parent is interactive
sprite.eventMode = "auto";
// Standard interaction: receives pointer/mouse/touch events
sprite.eventMode = "static";
// Like static, but also fires synthetic events from the ticker
// when the pointer is stationary (for animated objects under cursor)
sprite.eventMode = "dynamic";Use `'static'` for buttons, UI elements, and drag targets. Use `'dynamic'` only for objects that move under a stationary cursor and need continuous hover updates.
Use `isInteractive()` to check whether an object can receive events:
sprite.eventMode = "static";
sprite.isInteractive(); // true
sprite.eventMode = "passive";
sprite.isInteractive(); // false
Event types
Pointer events (recommended for cross-device compatibility): `pointerdown`, `pointerup`, `pointerupoutside`, `pointermove`, `pointerover`, `pointerout`, `pointerenter`, `pointerleave`, `pointertap`, `pointercancel`.
Mouse events: `mousedown`, `mouseup`, `mouseupoutside`, `mousemove`, `mouseover`, `mouseout`, `mouseenter`, `mouseleave`, `click`, `rightdown`, `rightup`, `rightupoutside`, `rightclick`, `wheel`.
Touch events: `touchstart`, `touchend`, `touchendoutside`, `touchmove`, `touchcancel`, `tap`. Each touch carries `altKey`, `ctrlKey`, `metaKey`, and `shiftKey` copied from the native `TouchEvent`, so modifier keys work the same as with mouse or pointer events.
Global move events: `globalpointermove`, `globalmousemove`, `globaltouchmove`. These fire on every pointer movement regardless of whether the pointer is over the listening object.
Container lifecycle events (no `eventMode` required): `added`, `removed`, `destroyed`, `childAdded`, `childRemoved`, `visibleChanged`.
Listening styles
import { Sprite } from "pixi.js";
const sprite = new Sprite();
sprite.eventMode = "static";
// EventEmitter style (recommended)
const handler = (e) => console.log("clicked");
sprite.on("pointerdown", handler);
sprite.once("pointerdown", handler); // one-time
sprite.off("pointerdown", handler);
// DOM style
sprite.addEventListener(
"click",
(event) => {
console.log("Clicked!", event.detail);
},
{ once: true },
);
// Property-based handlers
sprite.onclick = (event) => {
console.log("Clicked!", event.detail);
};Pointer events and propagation
import { Sprite, Container } from "pixi.js";
const parent = new Container();
parent.eventMode = "static";
const child = new Sprite();
child.eventMode = "static";
parent.addChild(child);
child.on("pointerdown", (event) => {
console.log("child pressed");
event.stopPropagation(); // prevent parent from receiving this event
});
parent.on("pointerdown", () => {
console.log("parent pressed (only if child did not stop propagation)");
});Capture phase events
All events support capture phase by appending `capture` to the event name (e.g., `pointerdowncapture`, `clickcapture`). Capture listeners fire during the capturing phase, before the event reaches its target.
container.addEventListener(
"pointerdown",
(event) => {
event.stopImmediatePropagation(); // blocks event from reaching children
},
{ capture: true },
);Hit testing
When a pointer event fires, PixiJS walks the display tree to find the top-most interactive element under the pointer. The traversal follows these rules:
- `eventMode = 'none'` on a container skips that element and its entire subtree.
- `interactiveChildren = false` on a container skips its children (the container itself can still be tested).
- A `hitArea` overrides bounds-based testing; only the shape is checked.
- Objects that are not visible, not renderable, or not measurable are skipped.
Set a custom `hitArea` to override bounds-based testing. This also speeds up hit tests on large or complex objects by reducing the geometry checked:
import { Sprite, Rectangle, Circle, Polygon } from "pixi.js";
const sprite = new Sprite();
sprite.eventMode = "static";
// Rectangular hit area
sprite.hitArea = new Rectangle(0, 0, 100, 50);
// Circular hit area
sprite.hitArea = new Circle(50, 50, 40);
// Polygon hit area
sprite.hitArea = new Polygon([0, 0, 100,Read more
