MCPE/Bedrock Extermobinators Add-On

Addon usage specifications:

• You can choose between 16 "extermobinators", each of them is specialized in acting in the presence of a type of mob, the craft, data and operation of each extermobinator is detailed at the bottom of this section.
• You can craft  the extermobinator spawn egg of your choice and spawn it in any type of zone, except lava zones. They do not need redstone or other fuel to work.
• The extermobinator will act [instant kill to mobs] and store resources, even if it is underground or hidden by other blocks or underwater.
• A dead extermobinator, disappears, and will not give you back its spawn egg, But its crafting is too cheap, and it is easy to make how many you need.
• Before killing an extermobinator, remember that you must empty its inventory that is useful to you, because once dead, the extermobinator will disappear along with the things stored in its inventory.
• Each extermobinator has a radius of action of 10 blocks, except 1. Eover [which instantly eliminates any hostile mob in the overworld, except the zombie villager] and 2. Enether [which eliminates hostile mobs in the nether]. These last 2 have a radius of action of 15 blocks.
• You can use all the extermobinators at the same time within your survival world, but you cannot place an extermobinator within the range of another extermobinator [10 blocks generally], even if they are both of the same type.
• Extermobinators are useful for collecting resources, however, when they exterminate any mob, they do not give you experience levels, unless you have hit the mob before being exterminated
• All extermobinators collect and store indefinitely in their inventory any type of item that is lying within their range of action, including items dropped by the mobs they have eliminated.
