- Camera

#- Draw to the screen texture

#- Update the screen with this texture

#- Resizing

- Smooth scrolling

#- UI camera

#- Screen pos to draw pos

- Better name for draw texture (world texture?)

- Improved creation AffineTransform options

- Add option to upsample to screen size

- Add feature to make UI for a reference, virtual screen size (width, and height) (=> Match the

screen height when upscaling, but stretch each x coordinate so that the width would match the screen width,

=> Scale x and y independently)

#- Make the position the center of the viewing field

- Only render objects that are visible

#- Make GamePanel the scene manager (handle the events properly add methods for setting the scene)

- Call start (component) at the beginning of the next frame and not directly

#- Call onDestroy after onUpdate / onDraw / ... => Make Component an IDestroyable and in GameObject register

the component for the destroy loop

- Add methods to get and to query all objects in the scene

- Collision engine

#- Detect collisions

#- Resolve collisions

#- Support layers

#- Add CollisionEngine to the Scene class

- Think about how to handle: shouldCollideWithOthers, shouldOthersCollideWithSelf

#- Rendering with SpriteRenderer

#- Scaling

#- Rotation

#- Sorting based on layers

#- Clean up code

#- Keyboard Handler

#- Mouse Handler

- Sound System

(- Create a SoundManager for loading and playing clips)

#- Sound class for representing a sound

- Preload the sound data of SoundEffects into memory before playing (and share this memory)

#- Call close() on each clip

- Load the sound in a separate thread

#- Rename Sound to SoundEffect

#- Music class for long sound files that need to be streamed from a file (with pause method for stopping without closing)

(https://docs.oracle.com/javase/8/docs/technotes/guides/sound/programmer_guide/chapter4.html)

#- 3D Sound System (pan and volume)

- Add close methods for Music, SoundEffect and SoundEffectInstance

#- Add pan to Music

#- Graphics Helper for drawing images

#- Time (.deltaTime, .time, ...)

- Make public methods that return a Vector2 return a copy

#- Add tags to GameObjects

#- Vector2: Get angle from Vector2, MoveToward

#- Simple random util class

#- Range function

#- Generate Vectors

#- Constants for Key ids (make a file called Keys)

#- Same for Mouse buttons

- Use javadoc comments

- Game Application

#- Move the main code (which sets up the window) into a separate class (Application)

- Add more methods for customisation (e.g. title)

- Add print() function to Components for ease of use (wraps System.out.println)

#- Improve the constructor of GameObject: Make a new constructor without parameters that defaults to the

active scene

- Update package name for the game engine (com.inspiaaa.decaf?)

- Mouse and Keyboard: make the setButtonState method public

- Mouse and Keyboard: Run in two phases: UI and game phase. The UI should then be able to block the game input

from reaching the second phase

- Mouse: hide / show mouse pointer

#- Add mouse wheel API to Mouse

#- Document mouse wheel API

- Resources class for accessing files in a dedicated resources / assets folder

- Optimise imports

- Optimise rendering pipeline (less intermediate images)

- Reduce GC lag spikes due to unnecessary allocations (AffineTransform, Vector2, Rectangle, ...)

- 2d light system (alpha based masks without shadows)

- Improve formatting: Add space when casting (int)x => (int) x

- For scene: create an empty method create() that is meant to be overridden instead of using start()
