alpha :Number

The transparency value is 0-1 and the default value is 1, which means opacity. Changing the alpha value affects drawcall.
Inherited From:

anchorX :Number

X axis anchor. The value is 0-1
Inherited From:

anchorY :Number

Y axis anchor. The value is 0-1
Inherited From:

autoSize :Boolean

Specifies whether to compute wide and high data automatically. The default value is false.

Sprite is wide and high, defaults to 0, and does not change with the rendering content. If you want to get the width of the drawing content, you can set the property as true or get it by the getBounds method. Set to true, has some impact on performance.

Inherited From:

blendMode :String

Specifies the blending mode to use. Currently only support "lighter"".
Inherited From:

bottom :Number

The vertical distance (in pixels) from the bottom edge of the component to the base edge of its content area.

Inherited From:

cacheAs :String

Specifies whether the display object is cached as a static image. When cacheAs is changed, the child object is automatically cached, and the reCache method is invoked manually to update the cache.

It is proposed to cache complex content that is not constantly changing into a static image, which can greatly improve rendering performance. CacheAs has "None", "normal" and "bitmap". The three values are optional.

  • The default is "None" and does not do any caching.
  • When the value is "normal", the canvas cache is carried out in canvas mode, and the command cache is in webgl mode.
  • When bitmap is used, canvas mode is still the canvas cache, and the renderTarget buffer is used in webgl mode.

    • Webgl renderTarget cache model disadvantages: additional renderTarget objects will be created to increase memory overhead, cache area has a maximum 2048 restrictions, continuous redraw will increase CPU overhead. Advantages: drastically reduce drawcall, rendering the highest performance. *

    Inherited From:

    cacheAsBitmap :Boolean

    Specifies whether the display object is cached as a static image. Functions with cacheAs's normal mode. It is recommended to use cacheAs instead.
    Inherited From:

    Inherited From:

    hitTestPrior :Boolean

    Specifies whether mouse event detection preferentially detects itself or preferentially detects its child object. The mouse event detection occurs at the capture phase of the mouse event. At this stage, the engine will begin to recursively check stage and its child objects from stage until the target object is hit or missed.

    If false, the child object is preferentially detected, and when a child object is hit, interrupt detection is done to hit the target. If you do not hit any sub object, then the object detection; if true, then the priority detection object, if the object is not directly hit, interrupt detection, said did not hit the target; if the object is hit, further iterative detection of its children, in order to confirm the final target.

    Reasonable use of this property, can reduce the mouse event detection nodes, improve performance. Can be set to true: the developer does not care about the mouse event detection result of the child node of the node, which is the mouse event detection point of the node as its child node.

    The View component of the Stage object and UI defaults to true.

    Inherited From:

    mouseEnabled :Boolean

    Do you accept mouse events?. The default is false. If you listen to the mouse event, you will automatically set the property of the object and the parent node. The value of mouseEnable is true (if the parent node is manually set to false, it will not change). *
    Inherited From:

    mouseThrough :Boolean

    Is the mouse event collision detected with this object?. Collision detection occurs at the capture phase of the mouse event. At this stage, the engine will start testing stage and its child objects recursively from stage until it finds the hit target object or misses any object.

    The penetration indicates that the location of the mouse event is hit when it is in the drawing area of the object, and is independent of the object's width, height, and the hitArea attribute of the Rectangle object. If the sprite.hitArea value is a HitArea object, the mouse event response area of the object is declared explicitly, and the width, height, and mouseThrough attributes of the object are ignored.

    The properties that affect the target mouse event response area are: width, height, hitArea, and the priority sequence is: hitArea (type:HitArea), >hitArea (type:Rectangle), >width/height.
