World thing damage question

[Apeirogon]

How change damage using world thing damage?

This

Code: Select all

	override void WorldThingDamaged(WorldEvent e)
	{
	if(e.thing is "playerpawn")
	{e.damage * 0;} and {e.damage *= 0;} 
       }

dont work.

You can't. The event is triggered after the damage is inflicted.

Though with a custom actor I believe you can by changing the return value of DamageMObj

You would need to "heal" this thing damaged, and then apply some other damage.

I haven't tried it, but given how everything else works I'd be willing to be at least three drinks that anything that's taken a lethal amount of damage would be dead by this point, so it would only work for non-lethal hits.

Yes of course, that only counts if the victim hasn't died. I would suggest to make own Actor class (MyActor), and make all monsters inherit from this class. Inside MyActor override DamageMobj and do whatever you want with it.

Reason I ask this not because I dont know how override virtual function and inherit one actor from another.

I made monster randomization mod, which among other things, change damage of monsters. And I made it based on inventory items, for compatibility with all other mods.
But it can change only damage of a projectile, since projectile can point to actor which shot it. Hitscan and splash damage cant be changed in such way, because to force puff point to actor which "shot" it I must change flags on it before it spawn.

I found way to bypass this limitation, make another inventory item which add to actor buddha flag and then await command to remove it.
But this way hurt to performance and now I search way to force engine "ignore" monsters, which player dont see, as much as possible.

If you can afford to change EVERY monster in your mod to inherit from a custom actor class, then do it. The only downside is, if your monsters already inherit from some other monsters. So, if you have a CustomZombieman : Zombieman, and only differance between him and default zombieman is, say, health, that sucks, because you'll need to COPY all code from zombieman, inside gzdoom.pk3.
For a monster to inherit from an custom actor, you need to:
1) Every monster will have to have this after name:

Code: Select all

Class CustomZombieman : CustomActor
{
	(...)
}

As I said, this means you can't inherit from other monsters, so will have to copy some monsters code here if you did that.
2) Create CustomActor class

Code: Select all

Class CustomActor : Actor
{
	//This is empty
}

3) Create an overriden function DamageMobj in CustomActor

Code: Select all

Class CustomActor : Actor
{
	override int DamageMobj(Actor inflictor, Actor source, int damage, Name mod, int flags = 0, double angle = 0)
	{
		return Super.DamageMobj(inflictor, source, damage, mod, flags, angle);
	}
}

Now you can change the damage and other stuff and it will count for EVERY monster that is inheriting from CustomActor

Code: Select all

Class CustomActor : Actor
{
	override int DamageMobj(Actor inflictor, Actor source, int damage, Name mod, int flags = 0, double angle = 0)
	{
		damage *= 0.5;	//Example - all damage is halved
		return Super.DamageMobj(inflictor, source, damage, mod, flags, angle);
	}
}

If you are going with this approach you could also just subclass and replace all the monsters in the target iwad to avoid having to copy-paste the implementation around.
So maybe something like this - using an external function would help in case you need to tweak the logic later since it's only in one place:

Code: Select all

class DamageProcessor
{
    static int ScaleDamage(Actor target, int damage) {
        return damage * 0.5;
    }
}

And then:

Code: Select all

class CustomZombieman : Zombieman replaces Zombieman
{
   override int DamageMobj(Actor inflictor, Actor source, int damage, Name mod, int flags = 0, double angle = 0)
   {
      damage = DamageProcessor.ScaleDamage(self, damage);
      return Super.DamageMobj(inflictor, source, damage, mod, flags, angle);
   }
}

Unfortunately, I think any actor replacement technique would probably conflict with other mods that do the same thing, if that sort of compatibility is a goal (sounds like it may be.)

[Apeirogon]

And I made it based on inventory items, for compatibility with all other MONSTER REPLACING mods.

That what I means.

Try this with any monster mod.
