Remove a specific SKAction list from SKNode

Question

During the development of some interactions between different nodes, I realized that I needed to remove a specific list of actions from node. The current version of the Sprite-Kitframework provides some instance methods like:

• removeAllActions ()
• action (key for key: string)
• hasActions ()

Obviously, every action performed in my node has a key Stringto identify it. So I thought about what was very similar to removeAllAction, then I did the extension SKNode:

public extension SKNode {
    func removeAllAction(in list:[String]) {
       list.forEach { if self.action(forKey: $0) != nil { self.action(forKey: $0)?.speed = 0.0; self.removeAction(forKey: $0)}}
    }
}

And in my project, I can use it like:

let actionList = ["idle_walk_sx","idle_walk_dx","walk_dx","walk_sx","walk_idle_sx","walk_idle_dx","rotate_sx_dx","rotate_dx_sx"]
self.removeAllAction(in: actionList)

The code works well. But I am not sure of two factors:

• speed ( ), , . - , ?
• ( ) , ?

Answer 1

. , speed , + :

public extension SKNode {
    func removeAllAction(in list:[String]) {
        list.forEach { if self.action(forKey: $0) != nil { self.removeAction(forKey: $0)}}
        self.children
            .filter { $0.hasActions() }
            .forEach { $0.removeAllAction(in: list) }
    }
}
