[Already In] ACS Get level name and level lump name

[Nash]

Just ran into a situation where I need this. An ACS function that returns the level name, and the level lump name, as a string.

Currently hacking my way through this by assigning LevelNums to the levels in MAPINFO and just checking against that, but that won't work in the long run!

strParam appears to be able to do what you are requesting, doesn't it?

Code: Select all • Expand view

str nicename = strParam(n:PRINTNAME_LEVELNAME);
str lumpname = strParam(n:PRINTNAME_LEVEL);

This only goes for the active map, though. I'm guessing your request goes for any level number?

[Nash]

Ah, didn't know that was already readable but... I can't get it to work!

Code: Select all • Expand view


script "Script_StartGameInstance" Open
{
    str lumpname = StrParam(n: PRINTNAME_LEVEL);
    while (!GameInstanceCount)
    {
        if (lumpname != "TITLEMAP") // this condition is never met
        {
            ACS_NamedExecute("Script_WorldSetup", 0);
            Delay(1); // wait 1 more tic to let the initialization complete
            GameInstanceCount = 1;
        }
        Delay(1);
    }
}
 

EDIT: Nevermind, got it to work! Had to use a handy string compare function from ACSNet and change the condition to this:

Code: Select all • Expand view

if (!StringCompare(lumpname, StrParam(s: "TITLEMAP")))

The whole "strings are really integer indices to a string array" thing strikes again! I don't think any mathematical comparison of a StrParam with a constant would ever work as intended.

Yeah! Honestly it still confuses me to this day, I don't think I can fully wrap my head around it.

the way zdoom string Works is really weird, a char atribute would be really welcome.
but from what I understand, is like each string is stored into a single global matrix pointer, so the given number will be just the position of the script on that vector

like
strings[0] = "YES";
strings[1] = "NO;
strings[2[] = "E1M1".

if I remember if you do something like x = string[0]+string[1], x would have the result "YESNO" and it would add a new pointer with the name "YESNO"

[Xaser]

The issue is the opposite: Without use of StrParam, trying to do strings[0]+strings[1] in the example above would yield "E1M1", not "YESNO", because internally you're adding two integers together.

weird, I remember that doing that in skulltag would result in a yesno string, but if you subtract it, it would Always be " "
but, this is not skulltag
