                            {
                            	boolean ignorar = false;
                            	
                            
                            	if ((movingobjectposition.entityHit instanceof EntityEnderman))
                            	{ignorar = true;}
                            	
                            	if ((movingobjectposition.entityHit instanceof EntityMinecartChest))
                            	{ignorar = true;}

                            	if ((movingobjectposition.entityHit instanceof EntityMinecartContainer))
                            	{ignorar = true;}
                            	
                            	if ((movingobjectposition.entityHit instanceof EntityMinecartEmpty))
                            	{ignorar = true;}
                            	
                            	if ((movingobjectposition.entityHit instanceof EntityMinecartFurnace))
                            	{ignorar = true;}
                            	
                            	if ((movingobjectposition.entityHit instanceof EntityMinecartHopper))
                            	{ignorar = true;}
                            	
                            	if ((movingobjectposition.entityHit instanceof EntityBoat))
                            	{ignorar = true;}
                            	
                            	
                            	if (!ignorar)
                                {
                                  EntityLivingBase mob =(EntityLivingBase) movingobjectposition.entityHit;
                          	      mob.setHealth(mob.getHealth()-5);
                                }
                            }

soo i need a genral way to avoid damaging this kind of entity

I did something like this before, I really don't remember everything, but I remember, you need to create new arrow handler and when it hit, you need to give a poison potion to victim

[Ernio]

Few facts:

1. You can't do this:

EntityLivingBase mob =(EntityLivingBase) movingobjectposition.entityHit;

Without first checking if that movingobjectposition is Living.

if (movingobjectposition.entityHit instanceof EntityLivingBase)
{
((EntityLivingBase) movingobjectposition).doStuff();
}

 

2. That is NOT how you deal damage, mionecraft has DamageSources for a reason, it even has alredy made armour piercing sources and poison.

entityLiving.attackEntityFrom(DamageSource.XXX, float);

Look at DamageSources - you can use e.g DamageSource.starve to deal absolute damage, but that is not way to go, since if you die it will display you died of hunger. You can make your own DamagSource which will .setDamageIsAbsolute(); or .setDamageBypassesArmor()

 

3. To add poison you will need: (example)

entityLiving.addPotionEffect(new PotionEffect(Potion.poison.id, 50));
