Title: Easy way to create collison path
Post by: AustinFelipe on January 09, 2013, 11:30:02 pm

I just bought the tk2d and I'm really enjoying working, but I have one question, there is some program, some way to create a collision without having to do it manually? For example, you can analyze pixel by pixel, ignoring alpha pixels and make a map of collision.

I appreciate any response.

There isn't at the moment, but I'll be looking into that in a future update targetting the collision system.

Ok, if I want implement this function at runtime using 2D toolkit, like change the vertices colliders from sprite, what do you recommend?

Thanks for the fast answer...

You shouldn't change collider vertices at runtime, it is really really expensive. If you want to do something similar, I suggest creating multiple box colliders as children and manipulating them. Make sure that your sprite has a rigid body attached though, otherwise this will be expensive (but not anywhere as expensive as the other option) too.
