strength(to:duration:)

Declaration

class func strength(to strength: Float, duration: TimeInterval) -> SKAction

Parameters

• strength:

  The new strength for the field.

• duration:

  The duration of the animation.

Return Value

A new action object.

Discussion

When the action executes, the field node’s strength property animates from its current value to its new value.

This action is not reversible; the reverse of this action has the same duration but does not do anything.
