baseThe texture used to render the children.
The blend mode to be applied to the sprite. Apply a value of PIXI.BLEND_MODES.NORMAL
to reset the blend mode.
PIXI.BLEND_MODES.NORMAL
Readonly
childrenThe array of children of this container.
If set, this shape is used for culling instead of the bounds of this object. It can improve the culling performance of objects with many children. The culling area is defined in local space.
Should this object be rendered if the bounds of this object are out of frame?
Culling has no effect on whether updateTransform is called.
The cursor preferred when the mouse pointer is hovering over.
The mode of interaction for this object
The area the filter is applied to. This is used as more of an optimization rather than figuring out the dimensions of the displayObject each frame you can set this rectangle.
Also works as an interaction mask.
Sets the filters for the displayObject.
IMPORTANT: This is a WebGL only feature and will be ignored by the canvas renderer.
To remove filters simply set this property to 'null'
.
The hit-area specifies the area for which pointer events should be captured by this event target.
Whether this event target should fire UI events.
Whether this event target has any children that need UI events. This can be used optimize event propagation.
Returns true if the DisplayObject has interactive 'static' or 'dynamic'
Does any other displayObject use this object as a mask?
Used to fast check if a sprite is.. a sprite!

The display object container that contains this display object.
Optional
renderCan this object be rendered, if false the object will not be drawn but the updateTransform methods will still be called.
Only affects recursive calls from parent. You can ask for bounds manually.
If true PixiJS will Math.floor() x/y values when rendering, stopping pixel interpolation. Advantages can include sharper image quality (like text) and faster rendering on canvas. The main disadvantage is movement of objects may appear less smooth. Default to true here as performance is usually the priority for particles.
true
Should children be sorted by zIndex at the next updateTransform call.
Will get automatically set to true if a new child is added, or if a child's zIndex changes.
If set to true, the container will sort its children by zIndex
value
when updateTransform()
is called, or manually if sortChildren()
is called.
This actually changes the order of elements in the array, so should be treated as a basic solution that is not performant compared to other solutions, such as PixiJS Layers
Also be aware of that this may not work nicely with the addChildAt()
function,
as the zIndex
sorting may cause the child to automatically sorted to another position.
PIXI.Container.defaultSortableChildren
Optional
tabWorld transform and local transform of this object. This will become read-only later, please do not assign anything there unless you know what are you doing.
The visibility of the object. If false the object will not be drawn, and the updateTransform function will not be called.
Only affects recursive calls from parent. You can ask for bounds or call updateTransform manually.
Readonly
worldThe multiplied alpha of the displayObject.
Static
defaultSets the default value for the container property sortableChildren
.
If set to true, the container will sort its children by zIndex value
when updateTransform()
is called, or manually if sortChildren()
is called.

Static
prefixedThe angle of the object in degrees. 'rotation' and 'angle' have the same effect on a display object; rotation is in radians, angle is in degrees.
Readonly flag for destroyed display objects.
The height of the Container, setting this will actually modify the scale to achieve the value set.
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
PIXI.Graphics or a PIXI.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.
To remove a mask, set this property to null
.
For sprite mask both alpha and red channel are used. Black mask is the same as transparent mask.
import { Graphics, Sprite } from 'pixi.js';
const graphics = new Graphics();
graphics.beginFill(0xFF3300);
graphics.drawRect(50, 250, 100, 100);
graphics.endFill();
const sprite = new Sprite(texture);
sprite.mask = graphics;
At the moment, CanvasRenderer doesn't support Sprite as mask.
The center of rotation, scaling, and skewing for this display object in its local space. The position
is the projection of pivot
in the parent's local space.
By default, the pivot is the origin (0, 0).
4.0.0
The coordinate of the object relative to the local coordinates of the parent.
4.0.0
The rotation of the object in radians. 'rotation' and 'angle' have the same effect on a display object; rotation is in radians, angle is in degrees.
The scale factors of this object along the local coordinate axes.
The default scale is (1, 1).
4.0.0
The skew factor for the object in radians.
4.0.0
The tint applied to the container. This is a hex value. A value of 0xFFFFFF will remove any tint effect. IMPORTANT: This is a WebGL only feature and will be ignored by the canvas renderer.
0xFFFFFF
The width of the Container, setting this will actually modify the scale to achieve the value set.
Indicates if the object is globally visible.
The position of the displayObject on the x axis relative to the local coordinates of the parent. An alias to position.x
The position of the displayObject on the y axis relative to the local coordinates of the parent. An alias to position.y
The zIndex of the displayObject.
If a container has the sortableChildren property set to true, children will be automatically sorted by zIndex value; a higher value will mean it will be moved towards the end of the array, and thus rendered on top of other display objects within the same container.

Dispatches a synthetic event event to target and returns true if either event's cancelable attribute value is false or its preventDefault() method was not invoked, and false otherwise.
Dispatches a synthetic event event to target and returns true if either event's cancelable attribute value is false or its preventDefault() method was not invoked, and false otherwise.

Rest
...args: ArgumentMap<DisplayObjectEvents>[Extract<T, keyof DisplayObjectEvents>]Used in Renderer, cacheAsBitmap and other places where you call an updateTransform
on root.
const cacheParent = elem.enableTempParent();
elem.updateTransform();
elem.disableTempParent(cacheParent);
Return an array listing the events for which the emitter has registered listeners.
Calculates and returns the (world) bounds of the display object as a [Rectangle]PIXI.Rectangle.
This method is expensive on containers with a large subtree (like the stage). This is because the bounds
of a container depend on its children's bounds, which recursively causes all bounds in the subtree to
be recalculated. The upside, however, is that calling getBounds
once on a container will indeed update
the bounds of all children (the whole subtree, in fact). This side effect should be exploited by using
displayObject._bounds.getRectangle()
when traversing through all the bounds in a scene graph. Otherwise,
calling getBounds
on each object in a subtree will cause the total cost to increase quadratically as
its height increases.
The transforms of all objects in a container's subtree and of all ancestors are updated. The world bounds of all display objects in a container's subtree will also be recalculated.
The _bounds
object stores the last calculation of the bounds. You can use to entirely skip bounds
calculation if needed.
const lastCalculatedBounds = displayObject._bounds.getRectangle(optionalRect);
Do know that usage of getLocalBounds
can corrupt the _bounds
of children (the whole subtree, actually). This
is a known issue that has not been solved. See [getLocalBounds]PIXI.DisplayObject#getLocalBounds for more
details.
getBounds
should be called with skipUpdate
equal to true
in a render() call. This is because the transforms
are guaranteed to be update-to-date. In fact, recalculating inside a render() call may cause corruption in certain
cases.
Optional
skipUpdate: booleanSetting to true
will stop the transforms of the scene graph from
being updated. This means the calculation returned MAY be out of date BUT will give you a
nice performance boost.
Optional

Retrieves the local bounds of the displayObject as a rectangle object.
Calling getLocalBounds
may invalidate the _bounds
of the whole subtree below. If using it inside a render()
call, it is advised to call getBounds()
immediately after to recalculate the world bounds of the subtree.
Optional

The ParticleContainer class is a really fast version of the Container built solely for speed, so use when you need a lot of sprites or particles.
The tradeoff of the ParticleContainer is that most advanced functionality will not work. ParticleContainer implements the basic object transform (position, scale, rotation) and some advanced functionality like tint (as of v4.5.6).
Other more advanced functionality like masking, children, filters, etc will not work on sprites in this batch.
It's extremely easy to use. And here you have a hundred sprites that will be rendered at the speed of light.
