Hi. Just some questions about this example. The sphere starts blinking immediately after hitting play the first time. So I guess I did something wrong

The thing I don't quite understand is, if I'm not supposed to use the FSM Bool variable what do I use instead? Secondly, in the example I'm supposed to add a Bool Test action, yet it is never used. Do you mean perhaps I should use the "Player has key" to compare the bools?
