[ZSCRIPT] OnEngineInitialize() Not "Working" in UDB

[Kan3x]

Hello.

I have this issue with OnEngineInitialize() and Ultimate Doom Builder.

Basically:

I set a couple of global arrays inside OnEngineInitialize(), since I just need to load them once and that's it, arrays that help me handle several stuff in specific classes etc..
If I run the game through Slade3 or directly gzdoom, everything works perfectly fine, but if I run a map through UDB it seems that the Method doesn't get called.

Is this supposed to happen and I just lack the knowledge on why this is a thing or is it a bug of some sort or am I doing something wrong?

Is there a workaround to the issue? Because I find it pretty annoying having to run custom maps from Slade instead of UDB every time.

Thanks

It works fine for me. Do you have the project folder/PK3 added as a resource in the map options in UDB?

Yeah, everything works but those arrays in UDB D:

To better illustrate the process:

This is (part) of my Event code:

---

Code: Select all

class ArraysHandler : StaticEventHandler
{
    	[...]
	Array<name> dmgs;
	[...]
	
	override void OnEngineInitialize()
	{
		[...]
		dmgs.Clear(); //damage types
		[...]
		
		static const name validtypes[] =
		{
		'Melee',
		'Disease',
		'Acid',
		'Bludge',
		'Slash',
		'Pierce',
		'Silver',
		'HellFire',
		'Void',
		'Fire',
		'Ice',
		'Poison',
		'DrainLife',
		'Explosion',
		'Crush',
		'Quake',
		'Drowning'
		};
		for(int d = 0; d < 17; d++) //get all the valid damage types
			dmgs.Push(validtypes[d]);
	}
}

This is where I retrieve the array:

---

Code: Select all

Class Entity : Actor
{
	[...]
	Array<name> dmgtypes;
	[...]
	
	override void BeginPlay()
	{
		dmgtypes.Clear();
		ArraysHandler e = ArraysHandler(StaticEventHandler.Find("ArraysHandler"));
		if(e)
		{
			for(int d = 0; d < e.dmgs.Size(); d++)
				dmgtypes.Push(e.dmgs[d]);
				
		}
		Super.BeginPlay();
	}
}

And this is where I actually use that (while checking if the event works)

---

Code: Select all

Class WarrensMonster : Entity
{
	[...]
	
	override int TakeSpecialDamage(Actor inflictor, Actor source, int damage, Name damagetype)
	{
		A_Log(dmgtypes[0]);
		[...]
		return super.TakeSpecialDamage(inflictor, source, damage, damagetype);
	}
}

If I open up the map in UDB and damage any monster inheriting from WarrensMonster the game crashes and the error says: Array access out of bounds. Size = 0
If I do not open it up in UDB everything goes as planned and I get "Melee" logging after every damage done to those monsters.

I'm really confused If you say it works for you D:

I only tried a minimal example of OnEngineInitialize() containing a printf, and that works fine:

I don't know what could be causing this. All UDB should be doing is run gzdoom.exe with -iwad, -file, -warp, and -skill arguments set.

Just to test it out, I just tried the same thing you did here and it worked...

I also tried to see if my arrays were being "filled", again with console.printf() and they do!
It was beyond my comprehension D:

As a last resort I just tried to so if using PostBeginPlay() instead of BeginPlay() in my actor class could do the trick...
and apparently that's the issue...

I'm confused D: really happy that I found what was causing the problem, but still freaking confused because to me it doesn't make sense, unless I'm missing something here.

Do you, perhaps, know what is happening? It is like BeginPlay() is getting called before OnEngineInitialize() when playing in UDB
