Getting Started

NodeStateMachine

• To create a state machine add the NodeStateMachine to the desired object as shown in the demo.

Class

StateAbstract, abstract class that allows to define the different states

to define a new state you must create a class from the StateAbstract class and define its behavior.

Public methods

• void StateAbstract::create(owner·:·Node,·state_machine·:·StateMachine)
• Node StateAbstract::get_owner()
• void StateAbstract::transition_to(state:·StateAbstract)
• String StateAbstract::get_name()
• bool StateAbstract::is_class_state_machine()
• bool StateAbstract::is_class_state()

virtual methods

• void StateAbstract::_enter()
• void StateAbstract::_exit()
• void StateAbstract::_input(event : InputEvent)
• void StateAbstract::_process(delta : float)
• void StateAbstract::_physics_process(delta : float)
• void StateAbstract::_integrate_forces(state : Object)

private methods

• void StateAbstract::_set_name()

StateMachine

in charge of administering the states.
