Hi everyone, I wanted to create a duel mission, using DCS-SimpleSlotBlock SSB by Ciribob or Mist, specifically, to make sure that only one player can enter a certain area at a time, while the others are blocked, the zone becomes free again when someone inside disconnects or leaves the "back to Spectators", is it possible? suggestions? Thanks for the attention

So what is the issue with above mission? In cases like this, I try to stop and take a step back; usually, I've made some erroneous assumptions, try to keep holding onto some design that's wrong, or conflated some things that are actually distinct. I then write down what I want and why. Perhaps it would help if you explained why you need those zones at all, and how they figure in your decision making. What is their purpose? If you only need it to detect if a unit exists in the game, perhaps another condition like "Unit Alive" may work better for you? It may help to write down the conditions under which a unit becomes blocked, and under which a unit becomes free to enter. These transitions in states (blocked-->unblocked, unblocked-->blocked) usually follow clearly definable events, and the events are often what you are looking for. They are the conditions to encode in triggers.
