Is there any way to cause damage to an entity without making it temporarily invulnerable?

Resolved:

 

	protected void onImpact(MovingObjectPosition movingobjectposition) {
	if (movingobjectposition.entityHit != null && movingobjectposition.entityHit instanceof EntityLivingBase) {
		movingobjectposition.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), Damage);
		((EntityLivingBase)movingobjectposition.entityHit).hurtResistantTime = 0;
		((EntityLivingBase)movingobjectposition.entityHit).hurtTime = 1;
	}
	this.setDead();
}

 

			((EntityLivingBase)movingobjectposition.entityHit).hurtResistantTime = 0;
		((EntityLivingBase)movingobjectposition.entityHit).hurtTime = 1;
