How to add wall jumping to your games in a few lines of code.
Emanuele Feronato is back with a great little tutorial on wall jumping: "One nice feature I love to find in platform games is wall jump. It’s the ability to jump, hit a wall and jump again on the opposite direction. This ability is often used to let the player climb levels, jumping from wall to wall.
Thanks to Phaser and ARCADE physics, we can do it in just a few lines."
