Issue with select() and IsInInstance()

[Clamsoda]

Is there a reason why:

local inInstance, instanceType = IsInInstance()

returns BOOLEAN, TYPE

and

select(1, IsInInstance())

returns BOOLEAN TYPE together? Select(2, *) returns JUST the type, so why can't I return just the boolean?

Because select returns all values after the one specified, as well.

If you just want the first value, just do "local inInstance = IsInInstance()".

There is a way to force it to only return one value, and that's by wrapping it in parentheses, but there's no reason to do that here.

Nevermind, thank you.

Zzzzz -.-

I would be instrested with this force only the selected value. Is this some kinda new bug, i think it only returned the actually selected parameter.

Normal lua behavior, use (IsInInstance()) to only get the first.

Well obv. i want to use it on a different stuff like "print(select(2, GetWorldStateUIInfo(3)))" prints every parameter from the second one.

You need to wrap your function in parenthesis like so:

print((select(2, GetWorldStateUIInfo(3))))

If that doesn't work, try:

local _, state = GetWorldStateUIInfo(3)

Edit: Fixed a mistake.

It's not a bug, it's even documented as doing such. See Select() under Official Lua 5.1 Manual §5.1.

As mentioned earlier, encase the Select() call in parenthesis to only use the first return.
(The post by Clamsoda put them around the wrong function.)

print((select(2, GetWorldStateUIInfo(3))))
