ZScript Discussion

[Graf Zahl]

Sure. I'm busy with other stuff so if you want to help out I'd very much appreciate it.

[Major Cooke]

Only curious, but will ZScript allow for potential dynamic slopes by chance? I ask because... well, it seemed like randi originally was going to implement them when he brought the build engine over...

Particularly, adjusting vertices...

[ZZYZX]

Pretty sure SecPlane struct allows setting the slope. This way it should be possible to calculate new slope based on height at specific vertices and just set that. Correct me if I'm wrong here, haven't tried yet.

[Graf Zahl]

The main thing with dynamic slopes is writing a working thinker to perform the movement, the rest is not relevant. Should be even possible to do this yourself once the functionality has been exported.

[Major Cooke]

Seriously? Holy shit.

What's next, mapping with ZScript and generating sectors procedurally?

[ZZYZX]

The current problem is that ChangeHeight or normal changes don't update the OpenGL structures.
Otherwise slope changing works just fine already, in software that is.
So once that's fixed, anyone could write a thinker for dynamic slopes, or at least a quasi thinker in the form of an actor that you place in a sector and give it parameters.

[Graf Zahl]

or at least a quasi thinker in the form of an actor that you place in a sector and give it parameters.

That part won't work that well, you still have to call P_ChangeSector to handle actor placement in the sector. That and the flagging of the sector for updating the GL structures are really everything that's missing right now.

I'd still implement a ChangePlane function that takes care of the necessary bookkeeping than doing it all script side. If then something needs adjustment it can be done in a function that's on the safe side.

[Major Cooke]

Can't wait to see it happen. That's just exciting!

Now... About this new custom property definition implementation...

Code: Select all

property LowMessage: LowHealth, LowHealthMessage;

Does this translate to:

Code: Select all

LowMessage.LowHealth 50;
LowMessage.LowHealthMessage "Medkit found. Bleeding staunched."

Or is it:

Code: Select all

Default
{
	LowMessage
	{
		LowHealth 50;
		LowMessage "Medkit found. Bleeding staunched.";
	}
}

[Graf Zahl]

Check out the Medikit.

[Major Cooke]

Would this by any chance support arrays? I'm thinking it would because of args[].

[Graf Zahl]

Not yet.

[Major Cooke]

Is it possible to 'skip' one super call? I.e. I want to remove the time freeze flickering effect as the powerup starts to wear off and make it last the entire time.

Is this feasible?

Code: Select all

Super.Super.DoEffect()

[ZZYZX]

There should be qualified superclass call, but it is not yet implemented.
i.e. something like Actor.Tick().

[ZZYZX]

I'm trying to implement a third party ZScript parser here, and found a weird thing.
How come Shotgun class is defined before the class that it inherits from (DoomWeapon)? Is this normal? How does it work at all?

[Major Cooke]

ZScript (and I think DECORATE) were changed so actor loading is postponed until all the base ones are built up first, I think.
