Making friendly monsters hostile via script execute

[Guest]

What command do i need the script to call for the monster executing the script to turn hostile?
Im using UDMF and am trying to have a ZSDF dialog option initiate a fight between the player and npc.

How about using SetActorFlag to get rid of the FRIENDLY flag?

[Guest]

I tried getting SetActorFlag to work but it wont even compile the script.
#include "zcommon.acs"

script 1 (void)
{
{
SetActorFlag(0, "Friendly", false);
}
}
This is what i have in a test wad and everytime i compile the script it either says SetActorFlag is used but not defined or it tells me a ")" is missing somewhere.
My mapformat is UDMF and im using doom builder 2 if that matters

That's weird, I copied the script and it compiled normally for me in SLADE.
Maybe it's a DB2 thing?

[Guest]

It might be, i read that there isnt much that DB2 lacks so i kinda only know how to work with it.
I also only got into this a few days ago so it might be i miss something really simple and basic.
When i want to use the function mentioned on the zdoomwiki page SetActorFunktion do i need to type out every value given in the script too?
For example : "int SetActorFlag (int tid, str flagname, bool value);"
Do i need to type the integer only within () or before the function aswell?

#include "zcommon.acs"
int Demon = 0;

script 1 enter
{
SetActorFlag(Demon,"FRIENDLY","flase");
}

This is the basicly the example given on the ZDoomwiki page just without the if thing, since i just want it to set the flag of a friendly monster to false once i enter the level.
As said it wont even let me compile without the error message :"Function setactorflag is used but not defined." but i cant figure out what it wants from me.

If you don't plan on changing the integer on the fly, you don't need to define it anywhere outside the function itself.
If you set it to 0, it will change the flag of the activator, which is the player since it's an ENTER script.
This script will also play when a player joins, so if you want to execute this script only once, use an OPEN script.
(void) can be used if you want to execute the script manually too.

Don't forget to also assign a TID to the demon you want to affect.
0 will work only if the demon is executing the script.

So, instead of doing that, you can do this:

---

Code: Select all

#include "zcommon.acs"

script 1 open //open script executes only once when the map is loaded
{ //100 assuming the demon's tag is 100
    SetActorFlag(100,"FRIENDLY",false); //false should be outside of "quotes"
}

I tried to write your example in my script and i dont think i missed anything but it still gives me this message https://imgur.com/a/bujyB8V
I dont know if it matters but the script editor also doesnt react to the SetActorFunction by colouring it or showing suggestions like it does for print or HudMessage.

I think DB2's ACS might be just outdated, because I am able to compile it in SLADE.

[Guest]

Do i need to update my DB2, switch to a diffrent builder or can i just write it in salde?
Also if i do write scripts in slade do i need to select the text language manually or does it just adapt to whats written?

[Jarewill]

You can just write it in SLADE if you wish, though there are more advanced map builders now, like Ultimate Doom Builder.
It's your call though.

As for compiling scripts in SLADE, you don't need to set the text language, all it does is highlight functions and such.
You just need to write the script and press the compile button. (blue arrow)
With SLADE you will also need a compiler, like ACC.

Is there a way to seperate DB2 compatible commands from the rest when searching through Doomwiki?
I didnt see any UDB features wich i would need so i'd rather not switch builders.

I also tried to use SetActorProperty to change my monsters flag and it the script editor does regotnize the command but when i call the script the monster stays friendly.

Having the script just being a voidscript and calling via a walkover line didnt work for me either.

[Guest]

I figured it out. I now just have my mob call a void script with SetActorProperty and its good to go but i still can get SetActorFlag to work :/
But thank you for your help Jarewill

DB2 uses ACC to compile ACS scripts. Now, since DB2 is very old, the version of ACC it's shipped with is equally old. So download the latest ACC and overwrite the one used by the editor with it (it's been about four years since I last used any form of DB2 editor, so I can't tell you exactly where ACC is located in the DB2 installation, as I don't remember).
