Hi there!
I'm actually working on an small game like Canabalt. It's a very simple runner with a single touch to jump on different platforms. For now my player can run after the countdown and accelerate if he didn't meet any obstacle.
When the player jump on a platform he can hang on, climb and continue to run. But I have some trouble to do this, I create a collision box that check if the player is on a platform border and then play the climb animation and after that run again.
As you can see on the capx file there is a lot of bugs. I don't know if I'm using a proper method so if someone have another solution, it will be great!
Thanks!
