Solved Safest way to check a block's data without lagging the server?

Hey all, I was wondering what the safest way to go for checking a block's data.
The block I want to recheck/update is the beacon to see the tier and the players in range and then I want to do something to those players in range. Is it safe to use a bukkit runnable or what should I use?

 

@fireboyev
Use a bukkit runnable.

BTW: If you are worries about performance (which you should not)

• Run every second or every half-a-second. You don't need to be that precise.
• When there are no players online/in that world, return; so you don't need to loop through unnecessarily entities.

 

Thanks it worked. I'm also wondering: How would I be able to test if the player is within a certain radius of a location?

 

@fireboyev

1. Get the beacons location.
   
2. For loop through all the players in a world (World#getPlayers)
3. get the player's location and check if the distance between that location and the beacon's location is less than __ (BeaconsLoc#distance( player's loc) < ___ ) If this returns true, then the player is close to the beacon.

 

Thanks! It worked perfectly
