Hi!

 

Question in title. And...

I can do this without using ASM?

Do you mean to do something whenever a mob drops experience?

 

You can use LivingDropsEvent or PlayerPickupXpEvent. I'm not exactly sure what you want to do, but these seem like a good place to start.

Nope, but thanks. I wanna remove experience orbs if it will drop, for example from creeper. But mobs drops orbs with this stupid metod:

    protected void onDeathUpdate()
    {
        ++this.deathTime;

        if (this.deathTime == 20)
        {
            int i;

            if (!this.worldObj.isRemote && (this.recentlyHit > 0 || this.isPlayer()) && !this.isChild() && this.worldObj.getGameRules().getGameRuleBooleanValue("doMobLoot"))
            {
                i = this.getExperiencePoints(this.attackingPlayer);

                // !
                while (i > 0)
                {
                    int j = EntityXPOrb.getXPSplit(i);
                    i -= j;
                    this.worldObj.spawnEntityInWorld(new EntityXPOrb(this.worldObj, this.posX, this.posY, this.posZ, j));
                }
            }

            this.setDead();

            for (i = 0; i < 20; ++i)
            {
                double d0 = this.rand.nextGaussian() * 0.02D;
                double d1 = this.rand.nextGaussian() * 0.02D;
                double d2 = this.rand.nextGaussian() * 0.02D;
                this.worldObj.spawnParticle("explode", this.posX + (double)(this.rand.nextFloat() * this.width * 2.0F) - (double)this.width, this.posY + (double)(this.rand.nextFloat() * this.height), this.posZ + (double)(this.rand.nextFloat() * this.width * 2.0F) - (double)this.width, d0, d1, d2);
            }
        }
    }

Since Experience Orbs are entities I'd assume they're still spawned, so you can mess around with things like LivingSpawnEvent.CheckSpawn or LivingSpawnEvent.SpecialSpawn.

 

Maybe even the EntityConstructingEvent.

 

Another option might be to subscribe to LivingDeathEvent, and then make it die in a way that you define, that might work.

 

The last resort I can think of right now is that if none of the above work, you can try using the spawn events to make every creeper spawned actually spawn an instance of your own creeper class that extends EntityCreeper or whatever its called, and then override that method there. This would probably be a bad idea though, as it can mess with compatibility with other mods.

If I understand correctly, these methods do not give 100% accurate.

This method may not be compatible with other mods. I create some constructor for change drops of mobs. It must works with all mobs.

 

Maybe I should read about ASM-lib and somehow insert custom xp-drop event in the method OnDathUpdate?

You could create your own event and make a PR on the official github.

I'll try in the near future.
