How do I make a queue system on my server. I am currently making an anvil game where anvils fall and you have to dodge them. I want a queue system so not as many afk people get in the game. Example: right click a sign and your in the queue, right click the sign again and you leave the queue. Then you teleport to a box where the game starts. The players will spawn in random positions in the box and also the anvils will spawn randomly on the top of the box and each wave there will come more anvils. Winner gets coins and is able to buy cosmetics and items. If anyone can help me. Reply to this thread. Thanks for reading. Sincerily iaryx
