ZScript Documentation

[Cherepoc]

It probably should be mentioned in PostBeginPlay description that it is not always executed before state functions, so in some cases can not be used for one-time setups. See this.

[Graf Zahl]

You should use BeginPlay for those anyway because it is guaranteed to be called before the newly spawed actor is starting to interact with the world.

[Cherepoc]

Unfortunately, it's called before target pointer is assigned for the projectile, and I want to assign it's value to master. Neither function work in this case.

[Major Cooke]

Try giving it NOINTERACTION and NOBLOCKMAP, then have it turn off those flags in (Post)BeginPlay before calling the super function. That could at least ensure those processing things aren't interrupted at the very least.

[Graf Zahl]

That won't help much. CheckMissileSpawn, which explodes a projectile without space does not care about those flags at all.
If you absolutely need to modify a projectile after spawn, the only way to do it is using the low level interface to spawn it and modify it on the spawner's side.

[Major Cooke]

This is gonna be a looooooooooooooong list to get through...

[D2JK]

That reminds me: is there a function that takes a classname, and counts the total number of them at the time of the call?

[Major Cooke]

You can use a ThinkerIterator for that.

[Major Cooke]

Added ZScript variables, but it could use some validation as I'm not sure what all is actually correct.

[Major Cooke]

With GZDoom 2.3's release, I think it's time to redouble the efforts on documenting all this. Graf has removed the -zscript requirement, so it's official now.

[Major Cooke]

Wiki updated.

• Added the two remaining iterators.
• Added information about extending classes inside ZScript classes.

[Major Cooke]

Added a warning about overriding a player's Tick function. See here for details.

[D2JK]

I was wondering: if I have a known actor such as "Actor X", is it somehow possible to call GetAngle() using X in it directly, instead of having to first assign eg. "tracer = X;", then followed by GetAngle(1, AAPTR_TRACER)?

For example, GetAngle(1, X) doesn't work (expects a numeric type).

[Graf Zahl]

X.GetAngle(1)

[D2JK]

Hmm, no, that should be equivalent to "Get X's (relative) angle to its current target", which isn't what I'm after here.

Let me post some code illustrating what I'm trying to do for now:

Code: Select all

ThinkerIterator Searcher = ThinkerIterator.Create("MonsterBase");
Actor X;
while (X = MonsterBase(Searcher.Next()))
 {
  A_LogInt(GetAngle(1, X));
  // tracer = X;
  // A_LogInt(GetAngle(1, AAPTR_TRACER));
 }

This is called by a projectile, and actor X has no knowledge of the said projectile at the time of the call. I want to get the projectile's relative angle to X, so is my only option to simply use the commented-out lines of code?
