Programmatic State Machine

A simple state machine for Godot defined solely in code

This plugin defines two classes: State and StateMachine

Create a new StateMachine by defining a variable:

var state_m = StateMachine.create(self)

Add states by calling:

state_m.add_state("State Name", enter_func, process_func, physics_process_func, exit_func)

transfer between states using:

state_m.transfer("StateName")

The state machine will automatically handle state transitions and call the correct functions.

State Dependency

State dependencies are created to handle state transfers during asynchronous transfer calls.

To create a dependency, get the current state ID and save it to a variable. In the transfer call, pass the saved state ID as a parameter.

var state_id = state_m.get_current_state_id()

await get_tree().create_timer(1.0).timeout

state_m.transfer("NextState", state_id)
