Scripting

[DooMBoy]

OK, I've wrote and compiled a script for the version of E1M1 I've been working on, it looks like this:

#include "zcommon.acs"

script 1 void

{
Print s("Heh!");
delay (const:35);
}

I've created a switch, tagged the line ACSAlwaysExecute, and set the script to 1. Yet when I try to hit the switch, the game tells me "P_StartScript Script 1 not found."

Help!

Is the Behavior entry where it's supposed to be?

Print s("Heh!");

make that

print(s:"Heh!");

[Biffy]

DooMBoy, also be aware that the "delay" entry in your script does nothing except keep the script running for a second so you can't get more than one "heh" a second, unless you use AcsAlwaysExecute instead of AcsExecute.

There are also no brackets round 'void'

[Ichor]

Try this:

#include "zcommon.acs"

script 1 (void)
{
print(s:"Heh!");
delay(const:35);
}

[The Ultimate DooMer]

Damn, I forgot to mention the zcommon.acs thing this time. (I suggested it last time someone had this problem)

/me realises stupid mistake, but can't delete the post, so prints this message instead and says Doh!

I did exactly that, saved the file to the level, saved the Behavior, and still won't work. What next?

[The Ultimate DooMer]

There's certainly nothing wrong with the script code. Which editor are you using?

[DooMBoy]

The editor I am using is DeePSea. Though I have a sneaking suspicion that ZDoom 1.22 (the version of ZDoom that I'm using) is the wrong version to use.

[The Ultimate DooMer]

That's probably it. The latest version is at http://zdoom.notgod.com/ftp/123beta33.zip

[DooMBoy]

Well, I got my first script to execute! :)
Now, how do I put more than one script in a level and get it to execute?

[Fredrik]

Simply name your scripts script 1/script 2/script 3 etc. Change script number in the trigger line's args accordingly.

[DooMBoy]

I've tried that, and it doesn't work. It'll execute the first script, but no go with the second one. :(

[Biffy]

Use a different line to trigger the second script, not the same line as for the first. Make sure you pay attention to how it's triggered, as in walk-over, use, shoot, and whether you flag the line as repeatable or not, etc.

Later, when you want to use the same line for multiple scripts, change its texture, block or unblock it, you can look into setlineidentification and setlinespecial. Setlineidentification assigns a number to a line. Setlinespecial assigns the function or script number to the line.

Try having a look through Rick Clark's scripting tutorials ( http://zdoom.notgod.com/zdkb/scriptprimer.html ) in the Zdoom knowledge base ( http://zdoom.notgod.com/zdkb/ ). Some of the tutorials are quite involved, but a great many are very clearly and simply put. They tend to deal with WAD Author, but most of the priciples are easily transferable to other editors, especially where something like scripting is concerned.

How are you trying to set up your scripts? (Post your script here for detailed comments.)

Your OPEN script should contain all the specials that you want activated at startup. Your regular scripts will all be triggered after the game starts. (Some scripts may even be triggered by other scripts.) As Biffy said, make sure you have your linedef triggers set properly. Here is an example set of scripts:

#include "zcommon.acs"

script 1 OPEN

{ TranslucentLine(1,64); //Glass throughout map
Setlineblocking(1,BLOCK_EVERYTHING);//Glass throughout map
TranslucentLine(2,128); //Laser
SetLineSpecial(2,80,3,0,0,0,0); //Laser, script 3
TranslucentLine(3,128); //Force field SetLineSpecial(3,80,5,0,0,0,0); //Force Field script 5
Sector_SetColor(4,96,96,96); //Underwater color
Sector_SetColor(5,32,224,0); //Hydraulics (green)
Sector_SetColor(6,224,128,32); //Computers (orange)
Sector_SetColor(31,255,255,0); //Computers (yellow)
Ceiling_CrushAndRaise(25,96,128); //Pistons Sector_SetDamage(44,400,0); //Elevator shaft
ChangeCamera (const:7, 1, 0); //Opening cut scene
ACS_Execute (const:25, 0, 0, 0, 0); //Opening cut scene
}

//////////////////////////////////////////////////////////////////////
// Script 3: Activates laser barrier when player tries to cross //
// Disintegrates player //
//////////////////////////////////////////////////////////////////////

int laserflag;
script 3 (void)
{
if (laserflag==0)
damagething(400);
}

//////////////////////////////////////////////////////////////////////

script 4 (void)
{

setlinetexture (2, SIDE_BACK, TEXTURE_MIDDLE, "-");

laserflag=1;
print (s:"Laser has been deactivated.");
}

//////////////////////////////////////////////////////////////////////

script 5 (void)

}

int force1;
script 6 (void)
{
if (force1==0)
setlinetexture (3, SIDE_FRONT, TEXTURE_MIDDLE, "-");
setlinetexture (3, SIDE_BACK, TEXTURE_MIDDLE, "-");
setlineblocking(3, OFF);
force1=1;
print (s:"Force Field has been deactivated.");
}

Welcome back, Nigel. I trust your travels were enjoyable and at least somewhat relaxing.

Thanks, yeah, lots of travelling around the UK, getting drunk in many towns :-) Not sure if relaxing is quite the word, but great fun none the less. 7 weeks of vacation, only about 1 & 1/2 of which were spent at home.

Oh yeah, and (as always) nice clear, well laid out scripts as examples from the guy I did most of my copying and pasting from when trying to get a grip on how to put a script together.

[DooMBoy]

#include "zcommon.acs"

script 1 void
{
print {s:"Scripting is teh l337.");
}
