Bukkit Scheduler Extension

runOnServerThread

launch(SchedulerThread) {
	Thread.sleep(3000)
	runOnServerThread {
		player.world.spawnEntity<Pig>(player.location)
	}
}

If you have a coroutine which has blocking task, this coroutine must run on Bukkit Scheduler Thread. In some cases, you need access Bukkit API, this activity should be run on Server Thread, it's not worth to create a new coroutine run on Server Thread which only has some sync statement, so you can use function runOnServerThread.

bukkitAsync

bukkitAsync {
	Thread.sleep(3000)
}

Sometimes it's not necessary to use kotlin coroutine. The block after this function will be post to Bukkit Scheduler.
