How To Use

• Copy the 'dci' directory to any location within your Godot project.
• Begin your DCI coding journey with the following code:

# define data
class Person extends dci_data:
    var name: String = "Player"

# define role (Interactions)
class swimmer extends dci_behavior:
    func swim() -> dci_behavior:
        print("%s Swim." % data().name)
        return self
    
class superman extends dci_behavior:
    func fly() -> dci_behavior:
        print("%s Fly." % data().name)
        return self

# define context
class FlyContext extends dci_context:
    # override
    func _on_execute(data):
        assert(sender() is superman, "type not match!")
        sender().fly()

# create dci environment
var dci = dci_env.new()

# register role
dci.add_behavior("swimmer", swimmer)
dci.add_behavior("superman", superman)

# register context
dci.add_context("FlyContext", FlyContext.new())
dci.add_callable("FlyLambda", func(ctx: dci_context, data):
    assert(ctx.sender() is superman, "type not match!")
    ctx.sender().fly()
)

# data usage
var man: Person = Person.new().with(dci)

# cast role
man.cast("swimmer").swim() \
    .cast("superman").fly()

# cast and context execute
man.cast("superman").execute("FlyContext")
man.cast("superman").execute("FlyLambda")
