OpenPeripheral: detect nearest player

Hello everyone,

I have a program that open doors. It uses the getPlayerNames() command. This command detects all players within his range. I only want to detect the name of the nearest player to the sensor. How do I do this?

s = peripheral.wrap("top")
for i,v in pairs(s.getPlayerNames()) do
   print(v)
end
-- It detects all players within the range. But how to only detect the nearest?

Thanks in advance,
Len

There's a command to get the distance of the player from the sensor. Just add the 3 values it returns(x,y,z) together and compare them in a loop. Whichever has the lowest value, is the nearest player.

Thanks for the reply.

Wich command is it? Can you give me an example?

I forgot what it is, it's probably just stored in the table it returns actually. Check the commands using the docs program included with openP.

the method you must call is getPlayerData(username) which will return a table of information about the player. In said table there is a sub-table stored under the key 'position' which will contain the players location relative to the sensor, under the keys 'x', 'y', and 'z'.
