Hide and Seek Help

I'm currently making a hide and seek plugin and was wondering how I should set a block

I'm currently using protocol lib to set a player as a block and it works perfectly.

1. How should I check if the player hasn't moved for 5 seconds?
2. Should I set a block where the player is?
3. Should I check if the seeker hits the set block and if so set it as air.
4. Should I use a player move event or should I make a Bukkit runnablee which checks the player location every second. If so how do I use the bukkit runnable since I don't know how to do this part yet ( meaning do I need to put the run() inside the player move event or do I have to put it on the onEnable()?

 

What are you trying to do here? Make the player turn to blocks if they stand still for x time?

 

@BurnerDiamond For number 4, neither. When you want to schedule a task (put this at the point when you actually schedule it), put

Code:

new BukkitRunnable() {
  public void run() {
//put code here
  }
}.runTaskLater(plugin, 0L, 20L)
