Type Method

changeCharge(to:duration:)

Creates an action that changes the charge of a node’s physics body to a new value.

Declaration

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

Parameters

v

The new charge of the physics body.

duration

The duration of the animation.

Return Value

A new action object.

Discussion

When the action executes, the physics body’s charge property animates from its current value to its new value.

This action is not reversible.
