I'm using Godot 4 game engine and write code with GDScript. I've written a custom library that allows me to describe game logic in a declarative way
What does this code do?
```
var declaration = DDeclaration.new([
  DDeclare.new([
    DState.stack({
      "Counter": 0
    }),
    DEvent.stack(["Incremented"])
  ]),
  DSubscribe.to_ref("Incremented").do([
    DSetState.to_ref("Counter").value([
      DSum.new([
        DGetState.from_ref("Counter"),
        DStatic.new(1)
      ])
    ])
  ])
])

This code defines a custom library in Godot 4 using GDScript that describes game logic in a declarative way. The code creates an instance of `DDeclaration` with an array of `DDeclare` objects.
 
The `DDeclare` object contains two properties: `DState` and `DEvent`. `DState` represents the current state of the game and is defined using a `stack` method, which initializes a stack of values for a specific state key. In this case, the state key is "Counter", and its initial value is 0. `DEvent` represents a trigger for a specific event that can change the game state. In this case, the event is "Incremented", which means that when this event is triggered, the game state will change.
 
The second element in the `DDeclaration` array is `DSubscribe`, which listens for the "Incremented" event and executes a set of instructions defined by the `do` method. The instructions consist of a single `DSetState` operation, which sets the value of the "Counter" state key. The `value` property of `DSetState` is an array of instructions to calculate the new value of the state key. In this case, the new value is calculated using the `DSum` instruction, which adds the current value of the "Counter" state key (retrieved using `DGetState`) to a static value of 1 (represented by `DStatic`).
 
Overall, this code defines a game logic that tracks a counter, initializes it to 0, and increments it by 1 whenever an "Incremented" event is triggered.<|im_end|>

what is the point of doing this it is to complicated for me<|im_end|>

The point of using declarative programming in game development is to make it easier to describe complex behaviors and interactions between game elements in a structured and maintainable way. By using a custom library like the one you've created, you can define the game logic using a high-level, English-like syntax, which can make it easier to read and understand the code, and reduce the likelihood of errors.

However, if you find the syntax too complicated or the library too difficult to work with, you may want to consider using a different approach or a different library that better fits your coding style and skill level. Ultimately, the goal is to write code that is efficient, readable, and maintainable, so it's important to find the right tools and techniques that work for you.<|im_end|>
