"How do I ZScript?"

[ZzZombo]

Namespacing, look it up.

A more helpful answer:

For resources more than 8 characters long, you must specify the full path with extension. This behaviour is consistent across (almost) everything in GZDoom. If the resouce is 8 characters or less, then GZDoom will attempt to automatically determine the namespace of the resource based on what context the resource is being called.

[Xaser]

^ All good info. One additional bit:

This behaviour is consistent across (almost) everything in GZDoom.

The most notable exception is that sprites don't support long file names since their naming scheme is pretty critical to the way they work in the engine.

Relatedly, @vidumec: I notice your example is calling DrawImage on a resource from the "sprites" directory: is it an actual sprite? If not (e.g. it's a general HUD element or somesuch), you'll want to put those images in "graphics" instead, otherwise it may cause some troubles down the line.

I'm trying to get the player to have a constant Y offset of 1 by using floorclip, but it's kinda... not working, or only halfway working (the view has a tendency to bob up when the player stops moving).

Here's the best I could do:

override void Tick()
{
super.Tick();
floorclip = 1;
}

Having it reset on every tick is the only way I could get it to almost-work, even though any other actor would only need floorclip set one time to be constant. There has to be a better way to do this.

What's the correct usage of BlockLinesIterator? I can't find any examples. My code that does this:

Code: Select all

PlayerPawn p = players[consoleplayer].mo;
BlockLinesIterator bli = BlockLinesIterator.Create(p, 64);
while ( bli.Next() )
{
	Console.Printf(String.Format(CurLine.v1.p.x));
}

gives this error on startup:

Code: Select all

Script error, ":zscript.txt" line 13:
Cannot convert Pointer<Class<BlockThingsIterator>> to Pointer<Class<BlockLinesIterator>>
Script error, ":zscript.txt" line 14:
Unknown identifier 'bli'

I notice that the zscript-side declaration for BlockLinesIterator in wadsrc/static/zscript/base.txt names BlockThingsIterator, is that intentional or a typo?

Code: Select all

class BlockLinesIterator : Object native
{
	native Line CurLine;
	native Vector3 position;
	native int portalflags;
	
	native static BlockThingsIterator Create(Actor origin, double checkradius = -1);
	native static BlockThingsIterator CreateFromPos(Vector3 pos, double checkh, double checkradius, Sector sec = null);
	native bool Next();
}

Using ZScript, would it be possible to apply the "BRIGHT" keyword state to an actor, similar to how you would call a function?

Edit: Doy, there's a BRIGHT flag available.

[SuaveSteve]

Can ZScript currently be used to replace all your ACS scripts or is it just a supped up DECORATE?

Could I execute ZScript from a linedef trigger?

[Gutawer]

You can, through the ScriptCall ACS function, however for map scripting ACS is still the way to go. ZScript is more for gameplay mod scripting.

How do you make a writing "PERFECT!" to appear in GZDoom intermission screen when you get all kills, items and secrets, line in Zandronum?

	native static BlockThingsIterator CreateFromPos(Vector3 pos, double checkh, double checkradius, Sector sec = null);
	native bool Next();
}

Urgh! Of course that is a bug.

Changing those two references to BlockLinesIterator (and recompiling gzdoom.pk3 of course) gets me further, to this error which I'm not as sure how to fix:

Code: Select all

Script error, ":zscript.txt" line 18:
Unknown identifier 'CurLine'

I think it's best you open a bug report so that it can be fixed upstream...

Yes. thank you! That should be in the first place on the wiki.

[Major Cooke]

Huh. Interesting... I didn't know you could access the default properties...

Code: Select all

Speed = Default.Speed;

That's a neat trick!
