"How do I ZScript?"

[Gutawer]

That means it's in a ZDoom dev version (and forever will be, with ZDoom's death), GZDoom has had it in stable for a while now.

[Graf Zahl]

The Wiki is a bit behind, it still lists ZDoom 2.8.1 as the baseline.

It doesn't matter if it says "development version only"?

For future reference, if in doubt, click on the number to get to the changelog post, and check the date, and compare it to the date of the latest GZDoom release.

How can I easily check current state of an actor? ACS have "CheckActorState", but I didn't find anything in ZScript or Decorate.

Code: Select all

if (CurState == ResolveState("See")) {
    // ...
}

To get other actors' states, you can use pointers as always.

Thanks, exactly what I needed.

Actually, there seems to be some problems with this method.

Making a blind spell, which set monster state to "blinded" on it's spawn state, and then on active state it checks if the monster is still on "blinded" state.
The spell's target is the monster.

Code: Select all

		Spawn:
			S010 A 0 NoDelay 
			{
				A_PlaySound ("Spells/Blind"); 
				target.setStateLabel("Blinded");
				if(target.curState==target.resolveState("Blinded"))
				{
					A_Log("Target is blinded");
				}
			}
		Active:
			TNT1 A 0 
			{
				if(target.CurState != target.ResolveState("Blinded"))
				{
					A_Log("Not blinded anymore");
					return ResolveState("Null");
				}
				return ResolveState("Active");
			}

Unfortunately, on the second loop it goes through the check (as if the target's state is not "Blinded").
Fortunately tho, I found (in this thread) another method which works:

Code: Select all

 if(!(inStateSequence(target.Curstate, target.resolvestate("Blinded"))))

I don't know why this works and other does not.

How to GetUDMF*** in ZScript? I mean, what are the parameters? GetUDMF***("SomeCustomUDMFValueNameHere"); ?

[Arctangent]

So, I'm trying to think out how to do a third person thing, preferably using ZScript, and one thing I want to do is to make the player move in the direction they're moving while keeping the camera always pointed in the way they're aiming - with extra points if the player has a turn speed, as what I'm planning would have typical attack animations long enough for such turning to only give a minor amount of "circling" when going from moving 180 degrees and otherwise just be a nice visual effect.

Issue is, of course, is making it so that the player - the one getting the actual turn inputs - doesn't have their angle be immediately affected, but the camera instead. I figure one way to do it might be making the camera the player with the actual body being a true pawn, but I dunno how I feel about how proper that is, especially considering that would mean shoving +NOINTERACTION on a player.

Also, not quite ZScript related, but what's a good camera angle for a shooting thing, anyway? Over-the-shoulder is a natural choice, but that has the issue of having projectiles not actually follow the crosshair over long distances. As far as behind-the-back goes, I've had issues making sure that the crosshair can actually be in the center of the screen without the player's body blocking it.

[Gutawer]

RE: which camera angle to use (can't help with the first part, sorry) -
With over-the-shoulder, presuming you can get the view angle & pitch of the camera (hopefully possible, depending on how you implement the camera), you can then use LineAttack to do a raytracer (as described by Nash a page back) and determine where the player is actually aiming. From there, you can use trigonometry to offset projectiles & hitscans so they hit where the player is actually aiming. That will make attacks follow the crosshair even in over-the shoulder.

What does "exact" do in FindState?

[sonic_HD87]

Fortunately tho, I found (in this thread) another method which works:

Code: Select all

 if(!(inStateSequence(target.Curstate, target.resolvestate("Blinded"))))

I don't know why this works and other does not.

It seems that InStateSequence is used to check if an actor's state (arg1) matches the given state (arg2), since is a bool function. I think that using target.CurState == Target.ResolveState("Blind") is doing something else.

And if i got it wrong, well that's good since there's no documentation for those functions.

This is probably ultra basic and I'm just dumb but:

How do I normalize GetPlayerInput's INPUT_FORWARDMOVE and SIDEMOVE's output into range [-1.0, 1.0]? I mean, I want to use values between -1.0 to 1.0, not -/+10k++ or whatever it usually is.

EDIT: nvm got it

Code: Select all

            double input = GetPlayerInput(INPUT_SIDEMOVE);
            double normalizedInput = 1.f * input / 10240.;
 

[Major Cooke]

Code: Select all

// Slowing down?
			if ((udirget & BT_SPEED) || uwings)		
			{	
				// Forwards or backwards?
				udirforward = GetPlayerInput(MODINPUT_FORWARDMOVE) / 6400.0;
				// Left or right?
				udirside = -GetPlayerInput(MODINPUT_SIDEMOVE) / 6144.0;
			}
			else
			{
				// Forwards or backwards?
				udirforward = GetPlayerInput(MODINPUT_FORWARDMOVE) / 12800.0;
				// Left or right?
				udirside = -GetPlayerInput(MODINPUT_SIDEMOVE)  / 10240.0;
			}

This is the values for all the movements in case you need it.

Is there any equivalent of PickActor on ZScript?
