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
init(self: T, context: Context) -> boolean
监听器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
perform(self: T, pointerEvent: PointerEvent) -> ()
关联的 状态机监听器(State Machine Listener) 触发时调用。 该方法包含 PointerEvent 参数,描述触发交互的细节。
已弃用。 请改用带 ListenerContext 的 performAction;此重载可能会被移除。
type MyListenerAction = {}
function init(self: MyListenerAction, context: Context): boolean
return true
end
-- Add your transition logic here.
function perform(self: MyListenerAction, pointerEvent: PointerEvent)
-- perform action here
end
-- Return a factory function that Rive uses to build the Listener Action instance.
return function(): ListenerAction<MyListenerAction>
return {
init = init,
perform = perform,
}
end
performAction
performAction(self: T, listenerContext: ListenerContext) -> ()
关联的 状态机监听器(State Machine Listener) 触发时调用。 该方法包含 ListenerContext 参数,描述触发交互的细节。
type MyListenerAction = {}
function init(self: MyListenerAction, context: Context): boolean
return true
end
-- Called each time the listener fires.
function performAction(self: MyListenerAction, listenerContext: ListenerContext)
if listenerContext:isPointerEvent() then
print('clicked')
end
end
-- Return a factory function that Rive uses to build the Listener Action instance.
return function(): ListenerAction<MyListenerAction>
return {
init = init,
performAction = performAction,
}
end
