Hi!
I’ve tried out Godot and I really like it. I want to implement a state machine but I’m having trouble understanding why the input is sent twice to the state node while the state machine is only recording the input once. The question is for this demo: https://github.com/godotengine/godot-demo-projects/tree/master/2d/finite_state_machine
So the demo has a player_state_machine.gd that has a number of states, one state being idle.gd
The player_state_machine.gd has an input function that it inherits from a state machine class. It has a function that looks like this:
func _input(event):
print("send input to the state " + current_state.name) # I added this print
current_state.handle_input(event)
and the Idle.gd has the following code:
func handle_input(event):
print("received input from state machine") # I added this print
return .handle_input(event)
When running the project with the added prints the console shows that the idle.gd input is received twice when the state switches to the Idle state.
example output from the console:
send input to the state Idle
received input from state machine
received input from state machine
send input to the state Move
send input to the state Idle
received input from state machine
received input from state machine
The expected behavior for me is that the each sent input event should correspond to one received input event, which is why I’m struggling to understand.
I would love if someone can help me understand! This is also my first question here, any feedback on how I should phrase the question better is appreciated.
