im trying to make an AI plugin and i need to return more that one value, how would i do this, would i make lots of functions, each one returning separate values, and each function leading to the next one or what?

DBC functions can only return one value. So, you'd be best to use different functions to return different values. More info on why you need more than one return value would be helpful.

As long as you dimensionalize outside the function you can change anything and have as many separate values come out of functions as you want. Only non-dimed integers and strings don't keep the change in the functions ( b1 and a$ ).

Or you could use file commands to store data while your inside the function and read the data back in at anytime you want using file commands. Simply because the data is stored into a file on your computer just like anything else, I use file commands in every program I make. If you need help with them or something then just look here:

In the past, I've cheated by returning all the required info from the function in a string, though it depends on what data you want to return.

Numeric data can be converted to ASCII characters and strung together in a string and returned from the function.

Boolean (yes/no) data can be strings of "0"'s and "1"'s.

I agree with Grog though, that the easiest way is to use Arrays which you can access both inside and outside of functions.

Arrays, arrays.

Dim MyGlobalVariable(0)
MyGlobalVariable(0)=WHATEVAH

Underworld 1020, aside from the fact you're probably going to send your hard drive into an early grave, files are SLOW. Much slower than RAM, in any case.

Meh. TDK's string-thing works too. ^_^

can you still use the arrays if you include a function instead of having it as part of your source code?

Yep, as long as you declare the Array in you main source code.

Maybe not quite memory efficient (your program will run the same logic through multiple times to get all values), but it works.

function GetAnInsult$(pick)
if pick=1 then insult$="your mom"
if pick=2 then insult$="your dad"
if pick=3 then insult$="your face"
if pick=4 then insult$="phatty"
endfunction insult$

I dunno about you guys, but I'm really sick of these workarounds-I'm gonna nab DarkSDK or something before my brain explodes.


I'm going to eat you!
