监听器动作接口（ListenerAction）

当关联的 状态机监听器（State Machine Listener） 被触发时执行的动作。

更多信息见：Listener Action Scripts

方法（Methods）

init

监听器动作创建或附加时调用一次。

type MyListenerAction = {}

-- Called once when the script initializes.
function init(self: MyListenerAction, context: Context): boolean
  return true
end

function perform(self: MyListenerAction, pointerEvent: PointerEvent) end

return function(): ListenerAction<MyListenerAction>
  return {
    init = init,
    perform = perform,
  }
end

perform

关联监听器触发时调用。 包含 指针事件（PointerEvent） 参数。

type MyListenerAction = {}

function init(self: MyListenerAction, context: Context): boolean
  return true
end

-- Add your transition logic here.
-- `evaluate` is fired every frame while the transition is active.
-- Returning false prevents a transition, true allows a transition.
function perform(self: MyListenerAction, pointerEvent: PointerEvent)
  return true
end

-- Return a factory function that Rive uses to build the Listener Action instance.
return function(): ListenerAction<MyListenerAction>
  return {
    init = init,
    perform = perform,
  }
end
