basically you want to load openCCsensors, place your password accepting computer and place a sensor on one side of it, then open the computer in the Lua prompt while standing in the block where you will be accessing the password computer from normally, execute the following code:
os.loadAPI("ocs/apis/sensor")
s=sensor.wrap(sSide)
for k,v in pairs(s.getTargets()) do print("Username: "..k.."\nCDS: "..v.Position.x..", "..v.Position.Y..", "..v.Position.Z.."\n") end
and it will print out a list of detected players and their position relative to the sensor, your position is the one you need. in your actual password protecting program use coroutines to only allow people to enter a password if they are in that area (you can make it span multiple blocks). make your password protecting code into a function which accepts a parameter for the player name that way you can greet the player when you ask them for their password
os.loadAPI("ocs/apis/sensor")
local x=yourX
local y=yourY
local z=yourZ
local sense=coroutine.wrap(function()
local s=sensor.wrap(sensorside)
while true do
local tResults=s.getTargets()
for k,v in pairs(tResults) do
if v.Position.X==x and v.Position.Y==y and v.Position.Z==z then
coroutine.yield(k)
break
end
end
sleep(0.5)
end
end)
local pass=nil
local running=false
local evts={}
while true do
local r=sense(unpack(evts))
if type(r)=="string" and running then
pass(unpack(evts))
elseif type(r)=="string" and not running then
pass=coroutine.wrap(yourpasswordfunction)
pass(r)
running=true
elseif type(r)~="string" and running
pass=nil
running=false
end
local evts={os.pullEvent()}
end
basically what that should do is run a coroutine constantly checking positions of detected players, if one is at the required position then it starts the 'yourpasswordfunction' function and keeps running it until there is no longer a player detected there, if no-one is there and then someone arrives then it starts the function over from the beginning
if you do not understand or if you have trouble executing any of the above feel free to ask
