From Emanuele Feronato: "It’s being a long time since I showed you how to create a hook like the one used in Mikey Hooks using AS3 + Box2D and AS3 + Nape.
It’s still a great game concept, so let me show you how to create the same thing using Box2D + Phaser.
Despite being an extremely good looking effect, it’s very easy to create an hook using Box2D, you just have to play with distance joints."
