This condition is to be used when you want one or a number of inputs, outputs or Variables to be in a certain state before actions are started. It is probably the most common condition you will use when building a show.
If you want to create behaviours where conditions happen in a sequential order before actions are started, you need to use Variables.
We recommend you watch The Basics series of tutorial videos, where you can learn how to create and use behaviours like States match.
Examples
ONE: I want actions to start because 3 buttons are pushed at the same time.
TWO: I want actions to start because of 3 buttons being pushed at the same time but also when three specific lights are on (i.e. only when the lights are on and the buttons are pushed, will these actions happen). These lights might themselves be controlled by a separate Behaviour.
THREE: I want actions to be started when a Variable reaches 5
