AFAIK，您可以从 .sks 文件中获取 actions 字典.在这里，我有一个 MyCustomActions.sks 文件，其中包含一个操作 Pulse.

AFAIK, you can get the actions dictionary from the .sks file. Here, I have a MyCustomActions.sks file with an action Pulse.

guard
    let node = SKNode(fileNamed: "MyCustomActions"),
    let actions = node.value(forKey: "actions") as? [String:SKAction],
    let pulse = actions["Pulse"]
else { return }

print(pulse.duration)  // 0.6 seconds

从这里，您可以从 actions 字典中实现自己的 struct.

From here, you can implement your own struct from the actions dictionary.

要获取所有操作的名称，

To get all the name of actions,

let actionNames = actions.map { $0.key }  // ["Pulse"]
