Hey desvisco, I think I understand what you’re trying to achieve. There are many ways you could set this up, but here is one example: Your pre-game lobby can be determined by a group of spawnpads set to “island start” and “pregame only.” The next area, where players select their team, can be determined by a set of “primary” spawn pads. Here they can choose between 4 teams using the class selector zone, with each one being set to a different team. When they enter the class selector’s zone, you can use a teleporter device to move them to their team base. You can use a player counter device to determine how many people have entered that zone, and disable the zone after 3 entries. Finally, you can use a timer device and barriers to to initiate the round’s start. (ie. barriers around each base will drop when the timer ends).
If there is respawn enabled, you’ll want to make sure you disable the initial spawn pads and have backup team specific spawn pads at each base. Hope this helps!
