Version 0.2.1

Version 0.2.1 is a minor release with a host of technical changes and new features, most notably a new sprite draw system, cinematic mode & screenshots and player walk particles / held blocks!

We also now have a new way of downloading 2DMC! You can download a non-standalone release at the bottom of this page. This is a zip that contains an executable and the game assets and information. Download this if you want to change any assets or view anuy information provided with 2dmc without having to download the repo and set up the pip packages. Also use this if you want to take screenshots or make profiles!

Full changelog

Additions

Screenshot

  • Press F2 to screenshot
  • The screenshot image will be stored in a folder named "screenshots" in the same directory as main.py
  • The image will be the same resolution as the resolution of the game (1200 x 600)

Cinematic Modes

  • To toggle cinematic modes, press F3
  • There are 4 option to toggle through in order:
    • Show both the hotbar and crosshair
    • Hide both
    • Show crosshair but hide hotbar
    • Show hotbar but hide crosshair
  • The current cinematic mode state will be shown by a popup displayed on the top-right

Hand Held Blocks

  • Blocks will now physically appear in the player's hand when the player is holding an item

Walking particles

  • When the player walks at over 3 blocks per second, block particles would be spawned underneath its feet

2DMC logo

  • 2DMC now has... a logo! It will be shown on the top left corner of the game window and in Alt + Tab menu!
  • You can see it below:

Changes

  • Optimized particles with conditional collision testing
  • Text boxes now show their outer border / rect whilst in debug mode
  • Velocity now shows up as BPS (blocks per second) in debug
  • Paperdoll no longer covers held item when in inventory
  • Optimized chunk loading and structure generation
  • Spacebar is now also binded to jumping

Bug Fixes

  • Fixed particles occasionally falling into solid blocks
  • Fixed void fog particles spawning in extremely large numbers when the player enters the upper threshold of void fog particles
  • Fixed player being able to tunnel through blocks as FPS gets extremely low
  • Fixed player tunnelling when the window is moved, now, the game will just pause with dt being set to 0

Licensing

  • 2DMC is now an officially Open Source project!
  • It is licensed with the GNU General Public License v3
  • You can view the full license here!
  • All src/ files now have a short header to reflect this.

Technical Changes

  • Reworked the sprite system to allow better control over draw order, and to make the sprites easier to work with!

    • We now have a custom defined sprite class
      • This sprite class serves as a superclass for all other sprites, and provides a constructor and a number of methods that make all sprites compatible with our SpriteManager
    • We have a SpriteManager class that manages draw order, updates and other useful management functions
    • Draw order is defined in an automatic enumeration
    • Sprites can have a custom debug layer (debug information is rendered on a different layer to the sprite) or a regular debug layer (debug information is rendered on the same layer as the sprite)
    • If you want to get a better understanding of this system then you are best off looking at the code (particuarly sprite.py), be warned the code is kinda gross >.<

  • Velocity is now set and calculated with BPS (blocks per second)

  • We have implemented a Single Instance Superclass. This class ensures any subclasses can only have 1 instance of themselves at a time.

    • This is useful, for example for the inventory labels, where whenever you move the mouse a new label will spawn. However, we only want one label to spawn at a time. Previously this required a very complicated and extremely ugly system of kill methods and class attributes and conditional checks which was, in short, gross.
    • This system removes the need for this. Any sprite that inherits from SingleInstance and calls it's constructor will have this handled automatically
    • Demo (because the constructor is slightly confusing):
    class Foo(Sprite, SingleInstance):
  def __init__(self, layer: int | LayersEnum) -> None:
    Sprite.__init__(self, layer)
    SingleInstance.__init__(self, self) # The second self call passes the instance to SingleInstance, the first is just a __init__ thing ¯\_(ツ)_/¯

  • We have implemented a new system called "Information Labels"

    • These labels can be defined as "anything non-permanent that conveys information or any other content".
    • This includes images, popups, labels, toasts, ect.
    • Made a information label class to better how these labels are handled. Labels are considered sprites internally, and so can be given different layers
    • Labels are designed with OOP in mind. As of 0.2.1 the inheritance tree is as follows:
    InformationLabel
└── GenericTextBox
    ├── InventoryLabelTextBox
    └── HotbarLabelTextBox
    • NOTE: GenericTextBox also inherits from SingleInstance but this is hard to show on an inheritance tree.

  • Structure generation and chunk loading is now done slightly differently

    • Structure that extend into already existing chunks will simply place down the extra blocks directly into the neighboring chunk
    • Base block generation is now cached by position
    • Since perlin noise (which is used for cave generation) is very slow, it is now done once per loop instead of 64 times at once
    • The cave heighmap will be generate block by block while chunks are not loading, so that when chunks load, the heightmap values have already been cached
