Below is my code. When player (RigidBody2D) is entering the Apple (Area2D), only _on_Apple_body_entered be called, eating_apple never be called.
Apple.gd
func _on_Apple_body_entered(body):
# this function will be called
print("body entered")
Main.gd
var apple
# ...
func create_apple():
apple = preload("res://Apple.tscn").instance()
apple.connect("body_entered", self, "eating_apple")
add_child(apple)
func eating_apple():
# this function never be called
print("eating_apple")
Check your debugger! It is called, but as soon as this happens, an error message tells you what’s wrong with your function definition:
Error calling method from signal 'body_entered': 'Node2D(Node2D.gd)::eating_apple': Method expected 0 arguments, but called with 1.
Changing the function to func eating_apple(body): fixes this issue.
Hi Thomas, I forgot to mention that I have set the Gravity Scale of the Player to 0. If I set it to 1, then the signal will be triggered, so the error occurs.
I don’t understand why setting the Gravity Scale to 0 will cause the signal not be triggered

This could be caused by your RigidBody2D object going to sleep without movement. Set “can_sleep” to false in the inspector to avoid that.
