[1.15.2] Modifying Vanilla Mobs

[Fuffles]

Hey all,

I'd love to have a Creeper keep track of who ignited it (Flint & Steel), but to do that Im pretty sure I'd have to edit how Creepers work, right? Correct me if Im wrong here ofc, but if there aint any way, how would one exactly edit a mob's class?

PlayerInteractEvent#EntityInteract with some clever usage of a capability on the creeper probably would work.

Im attempting that but I can not save who did it. I need to have the 'igniter' during the entity death event. For some reason Im unable to add a NBT tag for this

Would you happen to be able to show your code? This is a very general statement. You should only need to store the UUID of the player.

                nbts.putUniqueId("ignitorUUID", interactor);
                ((CreeperEntity)interactee).readAdditional(nbts);
            }
        }
    }
    
    public static void onKillEvent(LivingDeathEvent deathEvent)
    {
        Entity srcEnt = deathEvent.getSource().getTrueSource();
        if (srcEnt instanceof CreeperEntity)
        {
            //check if srcEnt has the tag with a value and then give an advancement to the 'ignitor';
        }
    }

Tried with multiple read/write fns but whenever I got the data per cmd I always got nothing

This is not a capability, the nbt data is only useful when saving or loading a world in this case. What you've done is literally nothing since the data will never be read.

Then how could I store it somehow in the creeper entity?

hit a roadblock

IgniterStorage code

[...]
import net.minecraftforge.common.capabilities.Capability;
import net.minecraftforge.common.capabilities.Capability.IStorage;

public class IgniterStorage implements IStorage<IBasic>
{
    @Override
    public INBT writeNBT(Capability<IBasic> capability, IBasic instance, Direction side) 
    {
        CompoundNBT nbts = new CompoundNBT();
        nbts.putUniqueId("igniter", instance.getUUID());
        return nbts;
    }

    @Override
    public void readNBT(Capability<IBasic> capability, IBasic instance, Direction side, INBT nbt) 
    {
        instance.setUUID(((CompoundNBT)nbt).getUniqueId("igniter"));
    }
}

A Class is not an instance of Callable.

And if I may ask what do I replace it with exactly?

... okay, I dont know what I expected as a response besides maybe something useful
