Trigger script with weapon attack?

[Azagthoth]

Hello. According to the wiki, ACS_NamedExecute should be usable in DECORATE but I can't find any examples of how to do this. Let's say I want to trigger a script every time I punch/fire with "ACTOR Fist : Weapon", how would I do that? Or maybe I could make an ACS script that does this without changing the actor somehow? Or maybe I could add an AltFire attack to fist that doesn't do anything except triggering the script? Any ideas?

You just call it like any other action function:

Code: Select all

actor MyFist : Fist
{
    States
    {
        Fire:
            PUNG B 4
            PUNG C 4
            {
                A_Punch;
                ACS_NamedExecute("MyScript", 0);
            }
            PUNG D 5
            PUNG C 4
            PUNG B 5 A_ReFire
            Goto Ready
    }
}

The above example uses an anonymous function, which is equivalent to the following code:

Code: Select all

PUNG C 4 A_Punch
TNT1 A 0 ACS_NamedExecute("MyScript", 0)

Please note, however, that unless you're aiming for Zandronum compatibility, a ZScript-based solution would likely be a better way to solve your problem, although it depends on what exactly you intend to accomplish. In modern GZDoom, ACS should generally be used for map events only, with very few exceptions like SetAmmoCapacity.

Code: Select all

actor MyFist : Fist
{
    States
    {
        Fire:
            PUNG B 4
            PUNG C 4
            {
                A_Punch;
                ACS_NamedExecute("MyScript", 0);
            }
            PUNG D 5
            PUNG C 4
            PUNG B 5 A_ReFire
            Goto Ready
    }
}

I tried it but I got this error:

Script error, "THate.pk3:decorate.txt" line 8:
Sprite names must be exactly 4 characters

I'm very new to doom scripting so I'm probably missing something obvious but could you please explain in detail how to do this. I do need Zandronum compatibility btw.

Zandronum probably does not support anonymous functions (though I haven't used it in a very long time, so can't be sure). Try replacing this part of the code

Code: Select all

PUNG C 4
{
    A_Punch;
    ACS_NamedExecute("MyScript", 0);
}

with the second example from my previous post.

Yeah, that worked. Thanks!
