Hey there!

For my mod I've created a shotgun. This shotgun is spawning multiple bullets (15) flying in the direction the player is facing. Now if these 15 bullets hit one entity it only damages the entity one time not 15 times. But if the bullets hit two entities they damage each entity one time.

 

I am sorry if I mix things up here, I am not experienced in Minecraft modding or in Java.

private void shoot(World world, EntityPlayer player, ItemStack itemStack)
{
    if(!world.isRemote)
    {
        for (int i =0; i < 16; i++)
        {
            itemStack.damageItem(1, player);
            EntityShot entityShot = new EntityShot(world, player);
            entityShot.readFromNBT(itemStack.getTagCompound());
            entityShot.setHeadingFromThrower(player, player.rotationPitch, player.rotationYaw, 0.0F, 2.5F, 8.0F);
            world.spawnEntity(entityShot);
        }
    }
}

This is because entities have a hurt resistance time: when they are flashing red they cannot take additional damage.

You need to reset the hurt resistance time yourself to 0 when your shotgun bullets impact, allowing all of them to deal full damage.

 

I did this once back in 1.7:

Oh ok thanks, that solved it!
