> [!NOTE] 'rotation' and 'angle' have the same effect on a display object; > rotation is in radians, angle is in degrees.

Example

// Basic rotation
container.rotation = Math.PI / 4; // 45 degrees

// Convert from degrees
const degrees = 45;
container.rotation = degrees * Math.PI / 180;

// Rotate around center

skew

Get Signature

> get skew(): ObservablePoint

Defined in: node_modules/pixi.js/lib/scene/container/Container.d.ts:1054

Example

// Basic skewing
container.skew.set(0.5, 0); // Skew horizontally
container.skew.set(0, 0.5); // Skew vertically

// Skew with point data
container.skew = { x: 0.3, y: 0.3 }; // Diagonal skew

// Reset skew
container.skew.set(0, 0);

// Animate skew
app.ticker.add(() => {
    // Create wave effect
    container.skew.x = Math.sin(Date.now() / 1000) * 0.3;
});

// Combine with rotation
container.rotation = Math.PI / 4; // 45 degrees

width

Get Signature

> get width(): number

Defined in: node_modules/pixi.js/lib/scene/container/Container.d.ts:1102

Example

// Basic width setting
container.width = 100;
// Optimized width setting
container.setSize(100, 100);

Returns

Type Parameters

U

U extends ContainerChild[]

Parameters

children

...U

The Container(s) to add to the container

Returns

U[0]

The first child that was added

Example

// Add a single child
container.addChild(sprite);

// Add multiple children
container.addChild(background, player, foreground);

// Add with type checking
const sprite = container.addChild<Sprite>(new Sprite(texture));
sprite.tint = 'red';

addChildAt()

> addChildAt<U>(child, index): U

Defined in: node_modules/pixi.js/lib/scene/container/container-mixins/childrenHelperMixin.d.ts:161

Adds a child to the container at a specified index. If the index is out of bounds an error will be thrown. If the child is already in this container, it will be moved to the specified index.

When moving a child within the same container, childAdded and added events are not emitted because the parent-child relationship hasn't changed. Events only fire when a child is added from a different parent (or from no parent).

Type Parameters

U

U extends ContainerChild

Parameters

child

U

The child to add

index

number

The index where the child will be placed

Returns

U

The child that was added

Example

// Add at specific index
container.addChildAt(sprite, 0); // Add to front

// Move existing child (no events emitted)
const index = container.children.length - 1;
container.addChildAt(existingChild, index); // Move to back

// With error handling
try {
    container.addChildAt(sprite, 1000);
} catch (e) {

Returns

Container.getLocalBounds

The bounding area

Example

// Basic bounds check
const bounds = container.getLocalBounds();
console.log(`Width: ${bounds.width}, Height: ${bounds.height}`);
// subsequent calls will reuse the cached bounds
const cachedBounds = container.getLocalBounds();
console.log(bounds === cachedBounds); // true

getSize()

> getSize(out?): Size

Returns

Size

The size of the container.

Example

// Basic size retrieval
const size = container.getSize();
console.log(`Size: ${size.width}x${size.height}`);

container.getSize(reuseSize);
