| // | ||
| // @Regex ^on player prelogin$ | ||
| // | ||
| // @Triggers when a player starts to logs in to the server. | ||
| // This is during the EARLY authentication process, and should NOT be confused with <@link event player joins>. | ||
| // | ||
| // @Warning This is a very special-case handler, that delays logins until the events are handled on the main thread. | ||
| // Generally, prefer <@link event on player logs in>. | ||
| // | ||
| // @Context | ||
| // <context.hostname> returns an ElementTag of the player's hostname. | ||
| // <context.name> returns an ElementTag of the player's name. | ||
| // <context.uuid> returns an ElementTag of the player's UUID. | ||
| // | ||
| // @Determine | ||
| // QueueTag to cause the event to wait until the queue is complete. | ||
| // "KICKED" to kick the player from the server. | ||
| // "KICKED " + ElementTag to kick the player and specify a message to show. | ||
| // | ||
| // @Player When the player has previously joined (and thus the UUID is valid). | ||
