Openperipherals sensor peripheral

I'm trying to make some kind of a door system using the drawbridges from the mod tConstruct. I want to use the sensor from openperipherals to detect if a player is nearby. I can't get the pripheral to work.

This is my tets build:

As you can see it doens't work! Can you guys hepl me?

If that really si an openP sensor, and not an OCS sensor (about 90% seem to make that mistake), then the correct function would be

sensor.getPlayerNames()

Thanks, I found the function getTargets() somewhere on the internet… It is indeed the sensor from openperipherals. And how do you get the distance?

EDIT: I tested your function and it still doens't work…

(The sensor is at the right side)

If the peripheral is placed on the computer's left side, then you need to use peripheral.wrap("right"), and vice versa. Note that the opposite is true for turtles.

Try the following:

for i,v in pairs(sensor.getPlayerNames()) do
     print(i, ". ", v)
end

Hope it works :)/> i'm having troubles with makeing a door with it xD
