I've been working on a Skywars plugin, and now I need help with this issue. As you know, Hypixel's Skywars won't set players to spectator mode after they died, it allows them be in survival mode but they cannot damage players, break/place blocks, or be visible to other players. They seem to be completely invisible because they don't play a role in blocking an alive player's movement. So, what event is it? How do I do event.setCancelled(false); if a spectator is really blocking a player?
