This scene gives a more practice example of code free drag and drop and shows how to use tags and rules to control what can be draged to where. In this scene each drag item is idetified with a color and a number, each slot has either or both a number and a color.
Colorless slots can take any color
Numberless slots can take any number
Red slots can only take red blocks
Numbered slots can only take blocks of the same number
Using color and number is simply done to keep it simple and abstract you can greate any number and complex of tags you like (Weapon, Armour, Left Glove, Basic Attack, etc.) and use that to control drop behaviour.

The "Types" and "Filter Types" fields of Drag Item and Drop Container respectivly take Scriptable Objects. That is we use Scriptable Objects as unique identifiers to power our filtering system. This is better than simple strings in that comparing two Scriptable Objects is faster and less error prone than comparing two strings. We use the same system in the Heathen Behaviour to tag behaviours.
You can use any Scriptable Object you would like to represent a type. We have create a simple empty Scriptable Object called a Scriptable Tag which we use in this scene. Scriptable Tag has no long and not data it simply represents a unique referencable identifier.
You will find 4 items configured under the Canvas > Background > Inventory Game object. Each item has two "types" assigned. A type is simply a scriptable object and is used like a tag by the drop rules e.g. does the item have this tag, does that allow it or forbid it.
In the middle of the screen you will see 8 slots/containers located under the Canvas > Background > Simple Slots and Canvas > Background > Complex Slots Game objects respetivly, each slot is configured with "Filter Types" and "Mask Mode" which effects what items can and cannot be droped on it.
