There are no properties that match your current filter settings. You can change your filter settings in the index section on this page. index

attr

Properties configuration function
All properties in attrs will be set to the node,
when the setter of the node is available,
the property will be set via setter function.
attrs Object

Properties to be set to node

:

var attrs = { key: 0, num: 100 };
node.attr(attrs);

getScale ( ) Number

Returns the scale factor of the node. Assertion will fail when _scaleX != _scaleY.

:

cc.log("Node Scale: " + node.getScale());

setScale
(
  • scaleX
  • [scaleY =scale]
)

Sets the scale factor of the node. 1.0 is the default scale factor. This function can modify the X and Y scale at the same time.

The original point (0,0) is at the left-bottom corner of screen.
Usually we use cc.v2(x,y) to compose CCVec2 object.
and Passing two numbers (x,y) is more efficient than passing CCPoint object.

It's like a pin in the node where it is "attached" to its parent.
The anchorPoint is normalized, like a percentage. (0,0) means the bottom-left corner and (1,1) means the top-right corner.
But you can use values higher than (1,1) and lower than (0,0) too.
The default anchor point is (0.5,0.5), so it starts at the center of the node.

:

The anchor point of node.

:

cc.log("Node AnchorPoint: " + node.getAnchorPoint());

setAnchorPoint
