refactor

• refactor creating window to only return the window object (not WindowPtr and EclipseWindow)
• Attach renderer and former windowptr to the window object
• reduce reliance on SDL2 types, use our own
• reduce checking for == nil / != nil (when using SDL2 / return types), use Option[]
• rename procs for GameEvent

Changes

• Change the base class for everything to be GameObject (scenes, ui components, etc are now a GameObject)

  • GameObject stores components, a UID, and a name for the game object

• GameObject have to be manually create(), and then added to a scene allowing for reusability and cloning; the "original" is never used. (think of it like Godot; you have objects but you can put an infinite amount of a single object in a Node, each holding their own values and running their own scripts: thats the structure I want to move towards)

• change ComponentProc to be proc (o: GameObject) instead of proc (c: Component) for more versatility and use

• [x ] Add object class SpriteObject class (of GameObject)

• Remove old hardcoded movement code, move to game logic rather than engine

• Add "Attribute" Class, attachable to game objects for adding more data to them, as an alternative to using variables

  • addAttribute(attName: string, attValue: T) Raises if attribute not found, or T is invalid
  • getAttribute(attName: string): Option[T] Returns either some() or none()
  • setAttribute(attName: string, newAttValue: T) Raises if attribute not found, or T is invalid
  • removeAttribute(attName: string): Raises if attribute not found
  • T can be: string, int, bool, Vector2; potentially more

• New procs for GameObject:

  • destroy(o: GameObject) -- Removes the game object instance, and all associated components / attributes

• Add GameEvents to GameObject:

  • onCreate -- run when the entity is created
  • onDraw -- run when drawn
  • onUpdate -- run during updating
  • onDestroy -- Before its destroyed, could in theory delay destruction

• Make Once() return a different event connection type (GameEvent)

• Add support for passing parameters through GameEvent.Fire()

• Change InputKey and MouseKey Enums to follow Nim Style

  • also rename MouseKey to MouseButton

• make InputManager handle polling of events, along with auto conversion and as such only requiring the manager to be updated

• Add support for window flags (Window Flags: an optional seq of flag enums that gets converted into SDL2 window flags)

• Game changes:

  • when initalising, add a GameEvent
  • add overrideable Game.init proc for adding initialisation for the game (think function love.load())
  • add overrideable Game.update proc for updating parts (love.update())
  • overrideable Game.draw proc for drawing

Removals (undecided if temp or perm)

• Remove Deactivate() from GameEvent
• Un-export sdl2

Temp removals:

• Remove SceneUI
• Revert to old UI code

Potential changes

• Migrate to SDL3 (nsdl3 OR nim-sdl3)
  • Neither have support for SDL_ttf or SDL_image
  • nsdl3 has weird conventions
  • nim-sdl3 requires a ton of extra manual work (which, while it can be implemented into things like beginFrame/endFrame/close/run, is a lot more tedious)

OR:

• Migrate systems to use OpenGL over SDL2
  • more modern, consistently updated
  • more work needed for "simple" things, but less SDL2-isms.
