v9.24.0

added another simpler live online js edit https://code.pietal.dev/#/boilerplate/detect-collisions?pans=html,console to links in readme

added Usage in Browsers readme section

added explanation of third parameter in https://github.com/Prozi/detect-collisions?tab=readme-ov-file#raycasting System.raycast

v9.20.0

You can provide custom class to body create functions:

    import { System, Polygon } from "detect-collisions";

    const physics = new System();

    class MyPolygon extends Polygon {
      constructor(position, points, options) {
        super(position, points, options);
        this.foo = "bar";
      }
    }

    // create minimal MyPolygon and insert to system
    const myPolygon = physics.createPolygon({}, [{}], {}, MyPolygon);

    // true
    console.log(myPolygon.foo === "bar");
  });

this may be useful for any customizations

last optional parameter of system.create* is a class that extends the base class (extends Box for createBox, extends Circle for createCircle, etc.)

v9.18.1

You can now add body.userData of any type during creation or runtime.

You can type it throught body generic if you need to. UserDataType in each body is

Body<UserDataType = any> { userData?: UserDataType }

• merged #84
• added tests
• more strict lint code rules
• removed prettier
• added short readme note about userData

next I will work on

#37

in the next days - to use this

https://github.com/benchmark-action/github-action-benchmark

v9.17.0

merged and published #82

as a result:

https://prozi.github.io/detect-collisions/classes/Box.html#group

should be able to close

#80

also bumped dependencies to latest ofc

v9.16.0

Latest stable realase

Changes:
Some minor fixes and update deps

v9.11.1

we got faster! 🔥

added a few magical improvements, and improved naming of params in docs

this is a benchmark from few commits before:

values of course fluctuate but believe me we should be more performant by like 4%

v9.10.0

since I've finally found out that indexing by hashmap is fast but indexing array by number is instant get in javascript

I changed the way getSATTest and checkAInB work, possibly improving performance, but will have to check the benchmarks on circleci

v9.9.4

improved package readme regarding crucial thing that is body position

wrote that set position is in fact teleport
and move is a move towards angle with speed

also improved description of package fixing broken english (ponglish)

v9.9.3

few cool fixes/improvements like trimming not required dependencies

v9.9.0

• merged #78
• merged #79
• in response to issue #77 updated typescript to ^5
• in response to issue #68 clarified that setPosition is teleport and what OP wanted is most likely the new added function of body.move(speed, updateNow)
