ClassUtils

ClassUtils is a Godot Engine singleton designed to extend GDScript with features currently unavailable natively, specifically focused on enforcing abstract function implementations.

Features

• Abstract Function Checking: Automatically identifies if concrete classes fail to implement abstract functions defined in their abstract parent classes.

How to Use

1. Add as a Singleton: Add class_utils.tscn as a singleton in your Godot project settings.
2. Mark Abstract Classes: Above your abstract class's class_name declaration, add the line:

   "@abstract_class"
   class_name MyAbstractClass
   extends Node
   

3. Mark Abstract Functions: Inside the body of any abstract function, add the following assertion:

   func my_abstract_function():
       assert(false, ClassUtils.ABSTRACT_FUNCTION_MSG)
       # Your abstract function logic (if any default behavior is desired)
   

Promise Utility

Promise is a helper class designed to simplify asynchronous workflows in GDScript.
It allows you to await operations and check results in a structured way.

Example Usage

var promise: Promise = async_compute_value()
await promise.wait_for_fulfill()
assert(promise.is_correct(), promise.get_error())
var computed_value: float = promise.get_result() as float
