Release Notes

Keep up-to-date with the latest changes to the Arcade library by the release notes.

Version 2.6.0 (UNRELEASED)

Version 2.6.0 is a major update to Arcade. It is not 100% backwards compatible with the 2.5 API. Updates were made to text rendering, tiled map support, sprites, shaders, textures, GUI system, and the documentation.

  • Tiled Map Editor support has been overhauled.

    • Arcade now uses the .json file format for maps created by the Tiled Map Editor rather than the TMX format. Tile sets and other supporting files need to all be saved in .json format. The XML based formats are no longer supported by Arcade.

    • Arcade now supports a minimum version of Tiled 1.5. Maps saved with an older version of Tiled will likely work in most scenarios, but for all features the minimum version we can support is 1.5 due to changes in the Tiled map format.

    • Feature-support for Tiled maps has been improved to have near 100% parity with Tiled itself.

    • See Simple Platformer for a how-to, Tiled usage starts at Chapter 9.

    • See Community RPG or Community Platformer for a more complex example program.

  • Texture atlases have been introduced, texture management has been improved.

    • A sprite list will create and use its own texture atlas.

    • This introduces a new arcade.TextureAtlas class that is used internally by SpriteList.

    • Sprites with new textures can be added to a sprite list without the delay. Arcade 2.5 had a delay caused by rebuilding its internal sprite sheet.

    • As a side effect, sprites can only belong to one sprite list that renders.

    • The texture atlas portion of a sprite can be drawn to, and quickly updated on the GPU side.

      • To demonstrate, there is a new Mini-Map example that creates a sprite that has a dynamic minimap projected onto it.

      Screenshot of minimap
  • Revamped text rendering done by arcade.draw_text(). Rather than use Pillow to render onto an image, Arcade uses Pyglet’s text drawing system. Text drawing is faster, higher resolution, and not prone to memory leaks. Fonts are now specifed by the font name, rather than the file name of the font.

  • SpriteList optimizations.

    • Sprites now draw even faster than before. On an Intel i7 with nVidia 980 Ti graphics card, 8,000+ moving sprites can be drawn while maintaining 60 FPS. The same machine can only do 2,000 sprites with Pygame before FPS drops.

  • Shadertoy support.

    • is a website that makes it easier to write OpenGL shaders.

    • The new arcade.Shadertoy class makes it easy to run and interact with these shaders in Arcade.

    • See Shader Toy Tutorial and Asteroids.

      ../_images/cyber_fuji_2020.png ../_images/star_nest.png
  • Reworked GUI

    ../_images/gui_flat_button.png ../_images/gui_widgets.png ../_images/gui_ok_messagebox.png
    • UIElements are replaced by UIWidgets

    • Option to relative pin widgets on screen to center or border (supports resizing)

    • Widgets can be placed on top of each other

    • Overlapping widgets properly handle mouse interaction

    • Fully typed event classes

    • Events contain source widget

    • ScrollableText widgets (more to come)

    • Support for Sprites within Widgets

    • Declarative coding style for borders and padding widget.with_border(…)

    • Automatically place widgets vertically or horizontally (UIBoxLayout)

    • Dropped support for YAML style files

    • Better performance and limited memory usage

    • More documentation (GUI Concepts)

    • Available Elements:

    • WIP * UIWidgets contain information about preferred sizes * UILayouts can grow or shrink widgets, to adjust to different screen sizes

  • Scene Manager.

    • There is now a new arcade.Scene class that can be used to manage SpriteLists and their draw order. This can be used in place of having to draw multiple spritelists in your draw function.

    • Contains special integration with arcade.TileMap using arcade.Scene.from_tilemap() which will automatically create an entire scene from a loaded tilemap in the proper draw order.

    • See Simple Platformer for an introduction to this concept, and it is used heavily throughout that tutorial.

  • Camera support

  • Add a set of functions to track performance statistics. See Performance Information.

  • Added the class arcade.PerfGraph, a subclass of Sprite that will graph FPS or time to process a dispatch-able event line ‘update’ or ‘on_draw’.

    Screenshot of performance statistics
  • Documentation

  • API commands

    • arcade.get_pixel() supports getting RGB and RGBA color value

    • arcade.get_three_color_float() Returns colors as RGB float with numbers 0.0-1.1 for each color

    • arcade.get_four_color_float() Returns colors as RGBA float with numbers 0.0-1.1 for each color

  • Better PyInstaller Support

    Previously our PyInstaller hook only fully functioned on Windows, with a bit of functionality on Linux. Mac was just completely unsupported and would raise an UnimplementedError if you tried.

    Now we have full out of the box support for PyInstaller with Windows, Mac, and Linux.

    See Bundling a Game with PyInstaller for an example of how to use it.

  • Sound

    The sound API remains unchanged, however general stability of the sound system has been greatly improved via updates to Pyglet.

  • Fix for A-star path finding routing through walls

Special thanks to:

  • einarf for performance improvements, texture atlas support, shader toy support, text drawing support, advice on GUI, and more.

  • Cleptomania for Tiled Map support, sound support, and more.

  • eruvanos for the original GUI and all the GUI updates.

  • benmoran56 and everyone that contributes to the excellent Pyglet library we use so much.

Version 2.5.7


  • The arcade gui should now respect the current viewport

  • Fixed an issue with UILabel allocating large amounts of textures over time consuming a lot of memory

  • Fixed an issue with the initial viewport sometimes being 1 pixel too small causing some artifacts

  • Fixed a race condition in Sound.stop() sometimes causing a crash

  • Fixed an issue in requirements causing issues for poetry

  • Fixed an error reporting issue when reaching maximum texture size

New Features

Arcade should now work out of the box on We detect when arcade runs in replit tweaking various settings. One important setting we disable is antialiasing since this doesn’t work well with software rendering.

Alternative Garbage Collection of OpenGL Resources now supports an alternative garbage collection mode more compatible with threaded applications and garbage collection of OpenGL resources. OpenGL resources can only be accessed or destroyed from the same thread the window was created. In threaded applications the python garbage collector can in some cases try to destroy OpenGL objects possibly causing a hard crash.

This can be configured when creating the arcade.Window passing in a new gc_mode parameter. By default his parameter is "auto" providing the default garbage collection we have in python.

Passing in "context_gc" on the other hand will move all “dead” OpenGL objects into Context.objects. These can be garbage collected manually by calling Context.gc() in a more controlled way in the the right thread.

../_images/light_demo.png ../_images/astar_pathfinding.png ../_images/bloom_defender.png ../_images/title_animated_gif.gif ../_images/explosions.gif ../_images/animated.gif ../_images/transform_feedback.png

Version 2.4 Major Features

  • Support for defining your own frame buffers, shaders, and more advanced OpenGL programming. New API in Arcade Open GL.

    • Support to render to frame buffer, then re-render.

    • Use frame buffers to create a ‘glow’ or ‘bloom’ effect: Bloom-Effect Defender.

    • Use frame-buffers to support lights: Lighting Demo.

  • New support for style-able GUI elements.

  • PyMunk engine for platformers. See tutorial: Pymunk Platformer.

  • AStar algorithm for finding paths. See astar_calculate_path and AStarBarrierList.

Version 2.4 Minor Features

New functions/classes:

New functionality:

  • Support for logging. See Logging.

  • Support volume and pan arguments in play_sound

  • Add ability to directly assign items in a sprite list. This is particularly useful when re-ordering sprites for drawing.

  • Support left/right/rotated sprites in tmx maps generated by the Tiled Map Editor.

  • Support getting tmx layer by path, making it less likely reading in a tmx file will have directory confusion issues.

  • Add in font searching code if we can’t find default font when drawing text.

  • Added arcade.Sprite.draw_hit_box method to draw a hit box outline.

  • The arcade.Texture class, arcade.Sprite class, and arcade.tilemap.process_layer take in hit_box_algorithm and hit_box_detail parameters for hit box calculation.


hit_box_algorithm = “None”


hit_box_algorithm = “Simple”


hit_box_algorithm = “Detailed”

Version 2.4 Under-the-hood improvements


  • Simple Physics engine is less likely to ‘glitch’ out.

  • Anti-aliasing should now work on windows if antialiasing=True is passed in the window constructor.

  • Major speed improvements to drawing of shape primitives, such as lines, squares, and circles by moving more of the work to the graphics processor.

  • Speed improvements for sprites including gpu-based sprite culling (don’t draw sprites outside the screen).

  • Speed improvements due to shader caching. This should be especially noticeable on Mac OS.

  • Speed improvements due to more efficient ways of setting rendering states such as projection.

  • Speed improvements due to less memory copying in the lower level rendering API.


A brand new low level rendering API wrapping OpenGL 3.3 core was added in this release. It’s loosely based on the ModernGL API, so ModernGL users should be able to pick it up fast. This API is used by arcade for all the higher level drawing functionality, but can also be used by end users to really take advantage of their GPU. More guides and tutorials around this is likely to appear in the future.

A simplified list of features in the new API:

  • A Context and arcade.ArcadeContext object was introduced and can be found through the window.ctx property. This object offers methods to create opengl resources such as textures, programs/shaders, framebuffers, buffers and queries. It also has shortcuts for changing various context states. When working with OpenGL in arcade you are encouraged to use instead of This is important as the context is doing quite a bit of bookkeeping to make our life easier.

  • New Texture class supporting a wide variety of formats such as 8/16/32 bit integer, unsigned integer and float values. New convenient methods and properties was also added to change filtering, repeat mode, read and write data, building mipmaps etc.

  • New Buffer class with methods for manipulating data such as simple reading/writing and copying data from other buffers. This buffer can also now be bound as a uniform buffer object.

  • New Framebuffer wrapper class making us able to render any content into one more more textures. This opens up for a lot of possibilities.

  • The Program has been expanded to support geometry shaders and transform feedback (rendering to a buffer instead of a screen). It also exposes a lot of new properties due to much more details introspection during creation. We also able to assign binding locations for uniform blocks.

  • A simple glsl wrapper/parser was introduced to sanity check the glsl code, inject preprocessor values and auto detect out attributes (used in transforms).

  • A higher level type Geometry was introduced to make working with shaders/programs a lot easier. It supports using a subset of attributes defined in your buffer description by inspecting the the program’s attributes generating and caching compatible variants internally.

  • A Query class was added for easy access to low level measuring of opengl rendering calls. We can get the number samples written, number of primitives processed and time elapsed in nanoseconds.

  • Added support for the buffer protocol. When requires byte data we can also pass objects like numpy array of pythons array.array directly not having to convert this data to bytes.

Version 2.4 New Documentation

Version 2.4 ‘Experimental’

There is now an arcade.experimental module that holds code still under development. Any code in this module might still have API changes.
