| The client I'm using is right on Aardwolf's homepage.
If I ran this:
print(CallPlugin("3e7dedbe37e44942dd46d264","gmcpval","char.vitals.hp"))
The output would be 0 100, and 100 is my hp. But how can I store this 100 in a script that's not a plugin? I tried doing s = (CallPlugin...) and print(s), and it simply printed 0.
Thanks for any help. | | Top |

| instead of s = (CallPlugin...) do
err,s = CallPlugin...
to get the second returned value put into s instead of the first. |

| I hardly know any Lua, so could you elaborate?
I just tried
err,s = (CallPlugin("3e7dedbe37e44942dd46d264","gmcpval","char.vitals.hp"))
and print(s) showed nil.
I must be doing something wrong, but I have no idea what it is. More help please. | | Top |

| Lose the brackets around CallPlugin. That forces Lua to throw away all returned values except the first. For example:
function foo ()
return 1, 2
end
a, b = foo ()
print (a, b) --> prints: 1, 2
a, b = (foo ())
print (a, b) --> prints: 1, nil
