Chickadee aims to +provide all the features that parenthetically inclined game developers +need to make 2D and 3D games in Scheme. + +Notable improvements and changes: + +* New `chickadee` executable for running games and producing + redistributable binary bundles for Linux. See [Command Line + Interface](/manuals/chickadee/Command-Line-Interface.html#Command-Line-Interface) + for more information. +* Support for Guile < 3.0 has been dropped. +* [Cube maps](/manuals/chickadee/Textures.html#Cube-Maps) are now a + supported texture type. +* New procedural [3D mesh + generators](/manuals/chickadee/Meshes.html#Primitives-and-Meshes) + for planes, tesselated planes, cubes, and spheres in the `(chickadee + graphics mesh)` module. +* New 3D [skyboxes](/manuals/chickadee/Skyboxes.html#Skyboxes) in the + `(chickadee graphics skybox)` module. +* New [3D model loading](/manuals/chickadee/Models.html#Models) with + support for glTF 2.0 and OBJ files in the `(chickadee graphics + model)` module. +* New [directional, point, and spot + lights](/manuals/chickadee/Lights.html#Lights) in the `(chickadee + graphics light)` module. +* New + [Blinn-Phong](/manuals/chickadee/Meshes.html#Blinn_002dPhong-Materials) + lighting model for 3D meshes in the `(chickadee graphics phong)` + module. +* New + [Physically-based](https://dthompson.us/manuals/chickadee/Meshes.html#PBR-Materials) + lighting model for 3D meshes in the `(chickadee graphics pbr)` + module. +* New linear and radial gradient fills in the `(chickadee graphics + path)` module. +* New `arc-to`, `bezier-path`, `right-split`, `up-split`, + `corner-split`, `square-limit`, `flip-horizontal`, and + `flip-vertical` procedures in the `(chickadee graphics path)` + module. +* Clockwise arcs now supported by `arc` procedure in `(chickadee + graphics path)` module. +* New mouse wheel event handler for `run-game`. (see [The Game + Loop](/manuals/chickadee/The-Game-Loop.html#The-Game-Loop)) +* `(chickadee math grid)` module moved to `(chickadee data grid)`. +* `(chickadee math path-finding)` module moved to `(chickadee data + path-finding)`. +* [Dynamic array API](/manuals/chickadee/Array-Lists.html) has been + made public. +* [Queue API](/manuals/chickadee/Queues.html) has been made + public. +* [Heap API](/manuals/chickadee/Heaps.html) has been made public. +* New [quadtree](/manuals/chickadee/Quadtrees.html) spatial + partitioning structure in the `(chickadee data quadtree)` module. +* New `current-timestep` parameter in `(chickadee game-loop)` module. +* Tweens now use the current timestep as their default step value. +* `vec2-dot-product` and `vec3-dot-product` are now named `vec2-dot` + and `vec3-dot` in the `(chickadee math vector)` module. +* `2pi` is now `tau` in the `(chickadee math)` module. +* New `look-at`, `look-at!`, `matrix3-inverse`, and `matrix3-inverse!` + procedures in the `(chickadee math matrix)` module. +* `#v` reader syntax for vectors is now *deprecated* and will be + removed in a future release. + +Bug fixes: + +* Fixed implementation of `vec2-cross` and `vec3-copy!` in the +`(chickadee math vector)` module +* Fixed implementation of `matrix4-rotate!` in the `(chickadee math + matrix)` module. +* Fixed looping of streaming sources in the `(chickadee audio)` + module. +* Fixed implementation of `below` procedure in the `(chickadee + graphics path)` module. + +source tarball: <https://files.dthompson.us/chickadee/chickadee-0.8.0.tar.gz> + +signature: <https://files.dthompson.us/chickadee/chickadee-0.8.0.tar.gz.asc> + +See the [Chickadee project page](/projects/chickadee.html) for more +information. + +Bug reports, bug fixes, feature requests, and patches are welcomed. + +Have fun! + +P.S. - The [2021 Autumn Lisp Game +Jam](https://itch.io/jam/autumn-lisp-game-jam-2021) is coming up on +October 15th! There are lots of great ways to make games in Lisp +these days, so there's never been a better time to join in on the fun! |
