A '''Blueprint''' is a description that Castle can use to create [[Actor|Actors]]. Blueprints include almost everything about an actor, such as how it appears, how it moves, and how it behaves in the card.[[File:Hazard snake blup.png|thumb|Viewing a 🐍  blueprint in the inspector]]
Blueprints are one of the fundamental building blocks of Castle decks. They can contain [[Art|Artwork]], [[Behavior|Behaviors]] describing motion and controls, sounds, music, [[Tag|Tags]], [[Rule|Rules]], and [[Variable|Variables]]. You can edit all of these properties of blueprints using the [[Inspector]].

== Relationship between Blueprints and Actors ==
A blueprint is a description for how to create an Actor, and an actor is one instance of a blueprint. For example, in a platform game, you might have one single '''Coin''' blueprint containing a drawing of a coin. But your level might have many instances of the coin scattered all around the level. These instances are actors and they all share the same '''Coin''' blueprint.

Many actors can be created and destroyed while a deck is played, but blueprints are only changed from the deck's editor.

== Adding blueprints to a card ==
To add new blueprints to a card, click the circular plus (+) button in the [[Belt]] at the bottom of the card. You'll see a menu with several premade blueprints to help you get started, along with the option to use a totally empty (blank) blueprint. Select something from this menu to add it to your card.

If you choose to create a new deck from a [[Kits|Kit]], the kit will come with several blueprints.
