Question by albertamg · Mar 02, 2014 at 09:50 PM · 2d collision physics2d

How to use `Physics2D.IgnoreCollision()` to implement a one-way platform?

According to this forum post, IgnoreCollision() is going to be added to the Physics2D API. Once it is added, what will be the right way to implement a one-way platform, i.e. a platform that can only be collided with from above?

When to enable/disable collisions between the character and the platform?
