The error "godot missing connected method" typically indicates that there is an attempt to connect a signal to a method, but the specified method does not exist or cannot be found within the given script or scene. This can happen due to several reasons:
Typo in Method Name: If you misspelled the name of the method when trying to connect the signal.
Incorrect Object Reference: The object to which you are trying to connect the signal does not contain the method you're attempting to connect.
Wrong Script Attached: The script containing the method is not attached to any node in the scene, or it's attached to a different node than expected.
Scope Issue: The method you're trying to connect to is not within the scope of the script that is making the connection.
Visibility: The method is declared as private (using the setget keyword) and thus is not accessible for the connection.
Solution - Here's How To Resolve It
To resolve the "godot missing connected method" error, follow these steps:
Check for Typos: Verify that the method name in the connect() function matches exactly with the method defined in your script, including case-sensitivity.
Ensure Correct Object Reference: Make sure that the object you are trying to connect the signal to is the correct one, and it has the script with the desired method attached.
Correct Script Attachment: Confirm that the script containing the method is correctly attached to the appropriate node in the scene.
Verify Scope: If the method is in a different script, you need to obtain a reference to the node that has the script attached and use that reference to connect the signal.
Method Visibility: If the method is set to private with setget, change its visibility so it can be accessed by the signal connection.
If you've gone through these steps and are still encountering the error, try the following:
Debugging Output: Use print statements or Godot's debugging tools to verify that the scripts and nodes are behaving as expected before the signal connection attempt.
Update the Scene Tree: Sometimes changes aren't recognized until you refresh the scene or restart the engine. Save your work and reload the scene or restart Godot.
Use Editor Autocomplete: When typing the method name in the connect() function, use the autocomplete feature provided by the Godot editor to ensure the method name is being referenced correctly.
Double-checking everything related to your signals and methods according to the above suggestions should help you resolve the issue.
