如果不久前发生，如何跳过活动？

不工作的代码：

Event = Something and SomethingElse and (ta.barssince(Event) > 20)

当然，它行不通，因为第一次尚未声明event boolean变量。

也许问题应该是“ 如何检查变量是否定义”？（我试图找到答案。）

尝试失败（事件的所有信号消失了）：

Event = Something and SomethingElse
Event := Something and SomethingElse and (ta.barssince(Event) > 20)

和

Event = false
Event := Something and SomethingElse and (ta.barssince(Event) > 20)

原文

The not-working code:

Event = Something and SomethingElse and (ta.barssince(Event) > 20)

Of course, it won't work because at first time, the Event boolean variable is not declared yet.

Perhaps the question should be "How to check whether a variable is defined or not"? (I have tried to find the answer.)

Failed attempts (all the signals of the Event disappear):

Event = Something and SomethingElse
Event := Something and SomethingElse and (ta.barssince(Event) > 20)

and

Event = false
Event := Something and SomethingElse and (ta.barssince(Event) > 20)

您可以使用var计数器。当您的事件发生并增加否则，将其重置。

n = input(2)

var bars_since_last_event = 0

bars_since_last_event := is_green ? 0 : bars_since_last_event + 1

You can use a var counter. Reset it when your event takes place and increase it otherwise.
