Dropping loot from enemies in any game should have an element of wonder, and to get that loot should be randomized and have a common to legendary drop rate, making it harder to get certain items.

I wanted to make this loot system simple to build and easy to populate. It allows for you to create and generate drops based on rarity and loot tables so enemies can have custom drop lists.

In this example we are using only one Drop List and have linked it to all of the rarity slots on the Loot Drop super unit. Ideally you would want to create a drop list for each of the rarity slots on the loot drop super unit.

If you wanted some items to drop 100 percent of the time you would attach that Drop List to the 100 Percent node. If you had a super rare list of item that should only drop 1 percent of the time you would attach that Drop List to the 1 percent node.. and so on for all of the percentage nodes.

This is an extensive loot drop system, you can cut back on how many percentage nodes you have and then amount of items available to be dropped in the Drop List to make it scale to a game with less loot options.

A look inside the first super unit:

This first super unit takes the 10 game objects that you drag and drop into the drop list slots and processes them into a list of game objects. If any of the drop item locations is left empty or if you only assign loot to a few random location, it takes that into account and still builds a list with no chances of an empty loot slot, preventing any errors right from the start. This loot list is then sent to the second super unit.

A look inside the second super unit:

This second super unit generates a random number between 0 and 100 and calls the right ‘percentage node’ to drop loot from. It them grabs the list of items in that percentage range and randomly chooses an item from that list of loot objects. It then takes that loot object and sends it out of the super unit to be sent to the Console window. This is where you can choose what to do with that loot drop in your game.

The Loot drop happened when I clicked the button in the middle of the screen showing that loot was indeed dropped.

There you have it a Loot Drop system the relies on Loot Tables and a percentage chance of dropping certain items for your game. Is this the best and only way to do it, no, but this is my way of doing it.
