The PlayerTick Event is fired each tick for each player on both client and server.

You will need to cast the event in the function header as this class:
crafttweaker.event.PlayerTickEvent
You can, of course, also import the class before and use that name then.

PlayerTick Events implement the following interfaces and are able to call all of their methods/getters/setters as well:

• IPlayerEvent
• ITickEvent

There is no additional information provided that is not already in the interfaces above.
