[SOLVED][1.12.2] Custom snowballs sometimes hitting thrower


Sunser

Recommended Posts

Hi all. Before I start, know that I'm beginning with MC mod developing, plus my English is not always very clear. :/

 

I'm trying to create custom snowballs. I have met some issues with the

protected void onImpact(RayTraceResult result);

function. Sometimes, the thrower receives the snowball's effects, and obviously not want this. This does not append with all of my custom snowballs.

EntityFlintSnowball : working correctly (I haven't change that much the original code from the snowball entity)

Spoiler

 


@Override
protected void onImpact(RayTraceResult result) {
	if (result.entityHit != null) {
		int i = 0;
		if (result.entityHit instanceof EntityPlayer) {
			i=2; 
		}
		result.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), (float)i);
	} 
	if (!this.world.isRemote) {
		this.world.setEntityState(this, (byte)3); this.setDead(); 
	} 
}

 

 

 

EntityTNTSnowball : working correctly (a bit more changes)

@Override
    protected void onImpact(RayTraceResult result)
    {
        if (!this.world.isRemote)
        {
            Explosion explosionIn = new Explosion(this.world,this.thrower,this.posX,this.posY,this.posZ,0.5F,false,true);
            EntityTNTPrimed entitytntprimed = new EntityTNTPrimed(this.world, (double)((float)this.posX + 0.5F), this.posY, (double)((float)this.posZ + 0.5F), explosionIn.getExplosivePlacedBy());
            entitytntprimed.setFuse((short)(this.world.rand.nextInt(entitytntprimed.getFuse() / 4) + entitytntprimed.getFuse() / 8));
            this.world.createExplosion(entitytntprimed, this.posX, this.posY + (double)(this.height / 16.0F), this.posZ, 1.0F, true);

            this.world.setEntityState(this, (byte)3);
            this.setDead();
        }
    }

        if (result.entityHit != null)
        {
            if (result.entityHit instanceof EntityPlayer)
            {
                PotionEffect eff = new PotionEffect(MobEffects.POISON,60);
                ((EntityPlayer) result.entityHit).addPotionEffect(eff);
                result.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), 0.0F);

            }
        }

        if (!this.world.isRemote)
        {
            this.world.setEntityState(this, (byte)3);
            this.setDead();
        }
    }

 

EntityFireSnowball : not working correctly

Spoiler

@Override
    protected void onImpact(RayTraceResult result)
    {
        if (result.entityHit != null)
        {
            if (result.entityHit instanceof EntityPlayer)
            {
                result.entityHit.setFire(3);
            }
            result.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), 0.0F);
        }

        if (!this.world.isRemote)
        {
            this.world.setEntityState(this, (byte)3);
            this.setDead();
        }
    }

 

All my snowballs are registered, rendered and working well apart from this problem. Please let me know if you have any idea. Thanks for reading.

As far as I know this is an issue from vanilla, the EntityArrow has an if clause to check if the owner was hit and ignores him. YOu could do similar checks respecting the age to make it possible to hit yourself if you throw it straight up.

catch(Exception e)

}

Yay, Pokémon exception handling, gotta catch 'em all (and then do nothing with 'em).
