An example of using the Separating Axis Theorem for collision handling with Phaser.
Check it out for yourself here!
PhaserSat.js is a heavily commented Phaser scene that puts all of this together.
I put this together because I'm terrible at maths and wanted to learn how to perform collision detection and response against sloped tiles. I wanted something like this from a fantastic tutorial by Metanet.
Even though Phaser has its Ninja Physics engine, which is ported from the very examples linked above, I wanted to see if it could be done more concisely.
In the end was able to achieve this thanks to the awesome SAT.js library and this very handy tutorial.
