This example is for 60 seconds. Press Green Flag to reset it. Useful for a variety of things, from cut-scenes in games to whole animations, all you need is to know how long it is and plug it in to the custom block! Sorry if it's laggy. UPDATE: okay, turns out it doesn't actually work, the timer is lagged and it's actually 62 seconds. I dunno how to fix this.(ಥ﹏ಥ)
Feel free to use this in any of your projects, but GIVE CREDIT! This is by far one of the best projects I've made.
