Checking if there are players close to another player

Hey, i need help with a plugin i am makeing.
What i need help with is makeing the plugin to see if there are any players within a 3x3 square around the other player after a certain event and get their names if there are. Thanks in advance =)

 

I think it's player.getNearbyEntitys() but I may be wrong.

 

Something like this should work

Code:

public void areTheyClose(Player primary) {
Location loc = primary.getLocation();
int x = loc.getX();
int y = loc.getY();
int z = loc.getZ();
for (Player p: player.getNearbyEntitys()) {
if (p.getLocation().getX() > x && p.getLocation().getX() + 3) {
//Player is in x bounds.
}
}

 

That will cause an invalid cast error.

for (Entity e : p.getNearbyEntities(1.5, 0, 1.5)) // change 0 to a number to account for players at different heights. Not sure if it will allow the 1.5's
{
String s = e instanceof Player ? ((Player)e).getName(); : null;
if (s != null)...
}

 

You would want to just do player.getNearbyEntities(3, 3, 3) which return a list of entities then just loop through it to find the players

 

That would be a box 6x6x6.

 

O ya then it would be (1,1,1) because that method goes that many blocks out from the entity you call it from thus creating a 3x3x3 cube.
