allowAn optional bounds area for this container. Setting this rectangle will stop the renderer from recursively measuring the bounds of each children and instead use this single boundArea.
This is great for optimisation! If for example you have a 1000 spinning particles and you know they all sit within a specific bounds, then setting it will mean the renderer will not need to measure the 1000 children to find the bounds. Instead it will just use the bounds you set.

Caches this container as a texture. This allows the container to be rendered as a single texture, which can improve performance for complex static containers.

// Children will always render if container is visible
container.addChild(sprite1, sprite2, sprite3);

Setting this to a custom Rectangle allows you to define a specific area for culling, which can improve performance by avoiding expensive bounds calculations.

eventEnable interaction events for the Container. Touch, pointer and mouse events are supported.
const sprite = new Sprite(texture);
// Enable standard interaction (like buttons)
sprite.eventMode = 'static';
sprite.on('pointerdown', () => console.log('clicked!'));
// Enable for moving objects
sprite.eventMode = 'dynamic';
sprite.on('pointermove', () => updatePosition());
// Disable all interaction
sprite.eventMode = 'none';
// Only allow child interactions
sprite.eventMode = 'passive';
Available modes:
'none'
: Ignores all interaction events, even on its children. Best for pure visuals.'passive'
: (default) Does not emit events and ignores hit testing on itself and non-interactive
children. Interactive children will still emit events.'auto'
: Does not emit events but is hit tested if parent is interactive. Same as interactive = false
in v7.'static'
: Emit events and is hit tested. Same as interactive = true
in v7. Best for buttons/UI.'dynamic'
: Like static but also receives synthetic events when pointer is idle. Best for moving objects.Performance tips:

filterThe area the filter is applied to. This is used as an optimization to define a specific region for filter effects instead of calculating the display object bounds each frame.

// Basic transform access
const localMatrix = sprite.localTransform;

Sets a mask for the displayObject. A mask is an object that limits the visibility of an object to the shape of the mask applied to it.
In PixiJS a regular mask must be a Graphics or a Sprite object.
This allows for much faster masking in canvas as it utilities shape clipping.
Furthermore, a mask of an object must be in the subtree of its parent.
Otherwise, getLocalBounds
may calculate incorrect bounds, which makes the container's width and height wrong.
For sprite mask both alpha and red channel are used. Black mask is the same as transparent mask.
// Apply mask to sprite

sprite.mask = graphics;
// Remove mask

nice performance boost.

Computes an approximate global bounding box for the container and its children. This method is optimized for speed by using axis-aligned bounding boxes (AABBs), and uses the last render results from when it updated the transforms. This function does not update them. which may result in slightly larger bounds but never smaller than the actual bounds.
for accurate (but less performant) results use container.getGlobalBounds
Optional
factorRenderLayers: booleanA flag indicating whether to consider render layers in the calculation.
Optional
bounds: BoundsThe output bounds object to store the result. If not provided, a new one is created.
The computed bounds.
Returns the global (compound) alpha of the container within the scene.
Performance optimization flag:

Returns the global position of the container, taking into account the container hierarchy.
Optional
point: PointThe optional point to write the global value to
Optional
skipUpdate: booleanShould we skip the update transform
The updated point
// Basic position check
const globalPos = sprite.getGlobalPosition();
console.log(`Global: (${globalPos.x}, ${globalPos.y})`);
// Reuse point object
const point = new Point();
sprite.getGlobalPosition(point);
// Skip transform update for performance
const fastPos = container.getGlobalPosition(undefined, true);
Returns the global (compound) tint color of the container within the scene.
Optional
skipUpdate: booleanPerformance optimization flag:
The resulting tint color as a 24-bit RGB number (0xRRGGBB)
Returns the global transform matrix of the container within the scene.
Optional matrix to store the result. If not provided, a new Matrix will be created.
Performance optimization flag:
The resulting transformation matrix (either the input matrix or a new one)
// Accurate but slower - recalculates entire transform chain
const preciseTransform = container.getGlobalTransform();
// Faster but may be outdated - uses cached transform
const cachedTransform = container.getGlobalTransform(undefined, true);
// Reuse existing matrix
const existingMatrix = new Matrix();
container.getGlobalTransform(existingMatrix);
Retrieves the local bounds of the container as a Bounds object. Uses cached values when possible for better performance.
The bounding area
// 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
Retrieves the size of the container as a [Size]Size object.
This is faster than get the width and height separately.
Optional
out: SizeOptional object to store the size in.

with support for options.
Optional

Remove the listeners of a given event.
Reparent a child or multiple children to this container while preserving their world transform. This ensures that the visual position and rotation of the children remain the same even when changing parents.

Updates the local transform properties by decomposing the given matrix. Extracts position, scale, rotation, and skew from a transformation matrix.

Used to set mask and control mask options on a display object. Allows for more detailed control over masking behavior compared to the mask property.

mask: graphics,
inverse: true, // Create a hole effect

if not provided.
