return cc.v2(this.width, this.height);
}
}

});
var obj = new Sprite();

obj.load();
_isCCClass
Checks whether the constructor is created by cc.Class
Parameters
Enum
Define an enum type.
If a enum item has a value of -1, it will be given an Integer number according to it's order in the list.
Otherwise it will use the value specified by user who writes the enum definition.
Parameters
obj object a JavaScript literal object containing enum names and values, or a TypeScript enum type
Examples
var WrapMode = cc.Enum({
Repeat: -1,
Clamp: -1
});
var FlagType = cc.Enum({
Flag1: 1,
Flag2: 2,
Flag3: 4,
Flag4: 8,
});
var AtlasSizeList = cc.Enum({
128: 128,
256: 256,
512: 512,
1024: 1024,
});
enum Direction {
Up,
Down,
Left,
Right
}
const {ccclass, property} = cc._decorator;
@ccclass
class NewScript extends cc.Component {
@property({
type: cc.Enum(Direction)
})
direction: Direction = Direction.Up;
}

Parameters
isValid
Checks whether the object is non-nil and not yet destroyed.
When an object's destroy is called, it is actually destroyed after the end of this frame.
So isValid will return false from the next frame, while isValid in the current frame will still be true.
If you want to determine whether the current frame has called destroy, use cc.isValid(obj, true),
but this is often caused by a particular logical requirements, which is not normally required.
Parameters
value Any strictMode Boolean If true, Object called destroy() in this frame will also treated as invalid.
Examples
var node = new cc.Node();
cc.log(cc.isValid(node));
node.destroy();
cc.log(cc.isValid(node));
cc.log(cc.isValid(node));
deserialize
Deserialize json to cc.Asset
Parameters
data String | Object the serialized cc.Asset json string or json object.details Details additional loading resultoptions Object
instantiate
Clones the object original and returns the clone, or instantiate a node from the Prefab.
Parameters
original Prefab | Node | Object An existing object that you want to make a copy of.
Examples
var scene = cc.director.getScene();
var node = cc.instantiate(prefabAsset);
node.parent = scene;
var scene = cc.director.getScene();
var node = cc.instantiate(targetNode);
node.parent = scene;
find
Finds a node by hierarchy path, the path is case-sensitive.
It will traverse the hierarchy by splitting the path using '/' character.
This function will still returns the node even if it is inactive.
It is recommended to not use this function every frame instead cache the result at startup.
Parameters
color
The convenience method to create a new Color/Color:method
Alpha channel is optional. Default value is 255.
Parameters
Examples
-----------------------
var color1 = new cc.Color(255, 255, 255, 255);
var color2 = new cc.Color("#000000");
var color3 = new cc.Color({r: 255, g: 255, b: 255, a: 255});
