"How do I ZScript?"

[Major Cooke]

Would it be better if all that just directly placed into Tick() then?

[Matt]

Going back to this topic...
Would anyone be able to teach me how to make a variant of A_RailAttack that honors autoaim?

From Graf's last comment it seems we just need to figure out what all this means from the Wiki:

double AimLineAttack(double angle, double distance, out FTranslatedLineTarget pLineTarget = null, double vrange = 0., int flags = 0, Actor target = null, Actor friender = null);
Actor, int LineAttack(double angle, double distance, double pitch, int damage, Name damageType, class<Actor> pufftype, int flags = 0, out FTranslatedLineTarget victim = null);

I can't access a copy of gzdoom.pk3 right now but I'm assuming this function is scriptified enough that the flags should be in there somewhere.


Also, can a mod maybe move the Darwinia sprite sloping stuff to a separate thread? It can get a little hard to follow a thread like this with something this complex going on at the same time.

[Major Cooke]

First off, it's already solved.

Second, it's a "How do I..." thread where it belongs. We really don't need to be making more as it would've been solved in good time anyway.

Third, it's a great place to look for things that may have been asked already. I say keep it.

ZScript "How do I..." thread is not going to be simple. The language itself is full of complex and/or internal stuff.

[Matt]

Guess I'll start the next question then! (notwithstanding I too want to know the answer to Ed's)

I want to do a for loop that goes through all the players on the map to do something to each of them. How would I set up this loop?

I want to do a for loop that goes through all the players on the map to do something to each of them. How would I set up this loop?

Now that one, I can answer! In this example, let's say I want to give every player one Clip:

Code: Select all

for(int i=0;i<MAXPLAYERS;i++)
{
	if(playeringame[i])
	{
		players[i].mo.A_GiveInventory("Clip");
	}
}

[ZZYZX]

Remember to check for .mo not being null. This can happen for spectators for example if ZScript ever gets to Zandronum.
Also under certain circumstances this probably could happen in GZDoom as well.

[Ed the Bat]

Yes, good catch. Always safer to have that net in place, just in case, right?

[Beed28]

How would I be able to remove all ammo and weapons currently present on the map? Using this doesn't seem to work, for example;

Code: Select all

Class ActorController : Actor
{
	int Monster_MaxHP;
	
	Default
	{
		+NOINTERACTION
		+NOTRIGGER
	}
	
	Override void Tick()
	{
		Actor ac;
		let it = ThinkerIterator.Create();
		while (ac = Actor(it.Next()))
		{

		if(ac.GetClass() == "Ammo" || ac.GetClass() == "Weapon")
			{
				ac.A_FadeOut(1.0);
			}

		}
		Super.Tick();
	}
}

small question: does SXF_TRANSFERPOINTERS transfer custom pointers?

[ZZYZX]

Should not. Remember classes have different field sets and checking for matching fields would be a bit of an overkill.

[Matt]

Thanks!
(I assume "&&(players.mo)" would do the trick? Or do I need to add a !=null after the mo?)


Beed: GetClass or CheckClass? Surely there's something in that function that lets you specify whether to check for an inheritance ancestor or not?


Questions:
How does using "GetGravity()" differ from using the word "gravity" (which seems to work)?

What's the difference between the AddInventory and GiveInventory (and GiveAmmo) functions? Does Add bypass pickup states? Do the first two ignore skill-based ammo doubling?

[Major Cooke]

@Beed28, I have just the thing you need.

Only it's a bit ridiculous since that's actually a setup template and what not, but it works. Summon AmmoRemover.

[Beed28]

Ah ha, I figured it out. Cheers.

Objects implicitly cast to bool like in C, yes.

AddInventory takes an Inventory object (possibly created using Spawn()).
GiveInventory takes a class name.
