/**
|
|
* Ninja Physics. The Ninja Physics system was created in Flash by Metanet Software and ported to JavaScript by Richard Davey.
|
|
*
|
|
* It allows for AABB and Circle to Tile collision. Tiles can be any of 34 different types, including slopes, convex and concave shapes.
|
|
*
|
|
* It does what it does very well, but is ripe for expansion and optimisation. Here are some features that I'd love to see the community add:
|
|
*
|
|
* * AABB to AABB collision
|
|
* * AABB to Circle collision
|
|
* * AABB and Circle 'immovable' property support
|
|
* * n-way collision, so an AABB/Circle could pass through a tile from below and land upon it.
|
|
* * QuadTree or spatial grid for faster Body vs. Tile Group look-ups.
|
|
* * Optimise the internal vector math and reduce the quantity of temporary vars created.
|
|
* * Expand Gravity and Bounce to allow for separate x/y axis values.
|
|
* * Support Bodies linked to Sprites that don't have anchor set to 0.5
|
|
*
|
|
* Feel free to attempt any of the above and submit a Pull Request with your code! Be sure to include test cases proving they work.
