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.
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.TextureAtlasclass 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.
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.
Fonts can be dynamically loaded with
Kenney.nl’s TTF are now included as build-in resources.
See the Drawing Text example.
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.
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)
UIFlatButton- 2D flat button for simple interactions (hover, press, release, click)
UILabel- Simple text, supports multiline
UIInputText- field to accept user text input
UITextArea- Multiline scrollable text widget.
UISpriteWidget- Embeds a Sprite within the GUI tree
UIBoxLayout- Places widgets next to each other (vertical or horizontal)
UIMessageBox- Popup box with a message text and a few buttons.
WIP * UIWidgets contain information about preferred sizes * UILayouts can grow or shrink widgets, to adjust to different screen sizes
There is now a new
arcade.Sceneclass 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.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.
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’.
Lots of individual documentation updates for commands.
The Quick API Index has been reorganized to be easier to find commands, and the individual API documentation pages have been broken into parts, so it isn’t one large monolithic page.
New tutorial for Ray-casting Shadows.
New tutorial for Shader Toy Tutorial.
Revamped tutorial: Simple Platformer.
Revamped minimap example: Mini-Map.
Moved from AWS hosting to read-the-docs hosting so we can support multiple versions of docs.
New example showing how to use the new performance statistics API: Performance Statistics
New example: GUI Widgets
New example: Flat Text Buttons
New example: OK Message Box
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.
The sound API remains unchanged, however general stability of the sound system has been greatly improved via updates to Pyglet.
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.
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
Arcade should now work out of the box on replit.com. 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
arcade.gl.Context 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
the default garbage collection we have in python.
"context_gc" on the other hand will move all “dead” OpenGL
Context.objects. These can be garbage collected manually
Context.gc() in a more controlled way in the the right thread.

Arcade 2.4.1 was released 2020-07-13.
Arcade version 2.4 is a major enhancement release to Arcade.
Version 2.4 Major Features¶
Support for defining your own frame buffers, shaders, and more advanced OpenGL programming. New API in Arcade Open GL.
New support for style-able GUI elements.
PyMunk engine for platformers. See tutorial: Pymunk Platformer.
For an example of using the A-Star algorithm, see A-Star Path Finding.
Version 2.4 Minor Features¶
Added get_display_size() to get resolution of the monitor
Added Window.center_window() to center the window on the monitor.
Added has_line_of_sight() to calculate if there is line-of-sight between two points.
Added SpriteSolidColor class that makes a solid-color rectangular sprite.
Added SpriteCircle class that makes a circular sprite, either solid or with a fading gradient.
get_distancefunction to get the distance between two points.
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.
arcade.Sprite.draw_hit_boxmethod to draw a hit box outline.
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=Trueis 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:
arcade.ArcadeContextobject was introduced and can be found through the
window.ctxproperty. 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
pyglet.gl. This is important as the context is doing quite a bit of bookkeeping to make our life easier.
Textureclass 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.
Bufferclass 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.
Framebufferwrapper class making us able to render any content into one more more textures. This opens up for a lot of possibilities.
Programhas 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
Geometrywas 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.
Queryclass 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
arcade.glrequires byte data we can also pass objects like numpy array of pythons
array.arraydirectly not having to convert this data to bytes.
