Type Method

scale(by:duration:)

Creates an action that changes the x and y scale values of a node by a relative value.

Declaration

class func scale(by scale: CGFloat, duration: TimeInterval) -> SKAction

Parameters

scale

The amount to add to the node’s x and y scale values.

sec

The duration of the animation.

Return Value

A new action object.

Discussion

When the action executes, the node’s xScale and yScale properties are animated to the new value.

This action is reversible; the reverse is created as if the following code is executed:

let action = SKAction.scale(by: -scale, duration: sec)
