"How do I ZScript?"

[kodi]

Do player actors necessarily have to inherit from PlayerPawn, or can I do

Code: Select all

class ModName_BaseActor : actor
{
stuff;
}

class ModName_PlayerActor : ModName_BaseActor
{
playerpawn stuff;
}

[Major Cooke]

You can only do playerpawn stuff if you have an actual playerpawn to work with. It can be done either way but know that you'll have to find A player pawn with the latter.

[Nash]

Code: Select all

            for (let i = index, a = borderAngle / 45.; a < 180.; i--, a += 45.)
            {
            }

I can't do this in ZScript? acc.exe allowed it... (specifically the last I-- and a += do not work; I can only assign one variable at the end here but not both. The initializer works fine)

[ZZYZX]

Please don't write code like that. It's unreadable.
Is it that hard to declare the variable outside?

[Nash]

Sure, I can declare them outside, but declaring the variables isn't the problem... the problem is assigning the two variables at the end.

Also, hopefully a simpler question: when you read an Actor's angle, the number can go below 0 and above 360. How do I wrap the values around so that I can reliably only get results between 0 and 360?

[ZZYZX]

Code: Select all

double ang = angle;
if (ang < 0) ang = 360.0-(ang % 360);
else ang = ang % 360;

Something like that. There might be a native function that does it however, and I'm not sure that % works on doubles in ZScript (in most languages it doesn't, but I remember that it kinda worked...)
In case % doesn't work,

Code: Select all

while (ang < 0) ang+=360; while(ang >= 360) ang-=360;

[Nash]

Thanks! Actually just doing this will normalize it nicely.

Code: Select all

double pa = CPlayer.mo.Angle % 360;
 

[Major Cooke]

Note that doesn't take into account if going from positive to negative. I.e. from 2 to -2, that won't handle it.

In the engine's case it's nothing to worry about because it automatically normalizes it when negative... I think.

Sorry to interrupt the backend talk, but does anyone know if an EventHandler has a function that can check a thing's state? I want to check to see if the currently dead actor has entered its xdeath state. In this context, e.thing.health < -e.thing.GetSpawnHealth() doesn't necessarily do the job since an actor's gibhealth property could change depending on its own gibhealth property or the gameinfo property. I apologize if this question has been asked already, I'm not sure what to search for in exact terms.

Migrating the question to this topic. Is it possible (yet)?

[Jimmy]

Is it possible to make a super rudimentary backpack item that just configures the MaxAmount of all types of ammo as I see fit?

And will this work via ACS script like the ammo change of a backpack apparently doesn't?

EDIT: [no]

[Gutawer]

@Jimmy - answering on ZDoom Discord

[Major Cooke]

Share it here too so others can see it.

But yes, the max amount of any item can be modified on a whim.

[Gutawer]

Turns out the issue was completely unrelated, some actor was replacing the wrong actor and it was fucking everything up, heh

i am basically the best at the zdooms

Not that I know an eventhandler from a hole in the ground at this point, but would something like

Code: Select all

if(thing.instatesequence(thing.curstate,thing.resolvestate("xdeath")))

work?


EDIT: Question of my own: is it possible to access an actor-defined variable in ACS somehow?
