Scripted crappage

int mapvar0;

script 8 (void)
{
	mapvar0++;
}

script 9 OPEN
{
	hudmessage(s:"score: ", i:"mapvar0", s:" points"; HUDMSG_PLAIN, 0, CR_UNTRANSLATED, 1.0, 0.0, 0);
}

For some reason mapvar0 in script 9 is completely unaffected by script 8. I'm trying to set up a simple score system.

You have to write i:mapvar0 instead of i:"mapvar0".
In this case "mapvar0" is just a normal string which in ACS gets converted into an index in the string table (let's say index 1). So your code says

hudmessage(..., i:1, ...);

and will happily print out the 1 (or whatever index it gets assigned to.)

i:mapvar0 did nothing either.

I think you have to call hudmessage again after changing the value.

That's correct, as the hudmessage won't change until you tell it to. Try this:

script 9 OPEN
{
hudmessage(s:"score: ", i:"mapvar0", s:" points"; HUDMSG_PLAIN, 0, CR_UNTRANSLATED, 1.0, 0.0, 0);
delay(1);
Restart;
}

Better try:

script 9 OPEN
{
hudmessage(s:"score: ", i:mapvar0, s:" points"; HUDMSG_PLAIN, 0, CR_UNTRANSLATED, 1.0, 0.0, 0);
delay(1);
Restart;
}

unless you want the index of the string "mapvar0" to be printed.

I tried putting it into a loop yesterday, and it still does nothing.

Ok, try this instead:

script 9 OPEN
{
hudmessage(s:"score: ", d:mapvar0, s:" points"; HUDMSG_PLAIN, 0, CR_UNTRANSLATED, 1.0, 0.0, 0);
delay(1);
Restart;
}

That's what I use in my scoring system, so it should work.

Arrgh. Now I see that it is an OPEN script. OPEN scripts don't belong to any actor in the game and thus the message isn't printed. Either use hudmessagebold to display your message or use an ENTER script.

int mapvar0;

script 8 (void)
{
	mapvar0++;
}

script 9 ENTER
{
	hudmessagebold(s:"score: ", i:mapvar0, s:" points"; HUDMSG_PLAIN, 0, CR_UNTRANSLATED, 1.0, 0.0, 0);
	delay(1);
	restart;
}

It's still not working.
