One-way platform's side causes collision with Platform Effector

I have a platform with an edge collider on the top and a platform effector set as One Way. However it’s not working as expected with my character (who has a Rigidbody2D and Box Collider 2D). When the character jumps towards a one-way platform but doesn’t jump high enough and hits the platform’s side, it just stops there instead of passing through the platform (like usually happens in games with one-way platforms). Changing any of the character’s rigidbody’s settings or the effector’s settings doesn’t help.

Any ideas how to resolve this? Thanks in advance!

The PlatformEffector2D ‘surfaceArc’ property controls what is the surface (the part that you actually collide with). By default it is 180-deg thus the left/right edges are included in the surface by default. Simply reduce the surface arc by 1-deg or more depending on what you want.

Note that he angle is the angle of the collision normal so imagine a CircleCollider2D used as a platform; touching the very top would be zero degree, touching the top/left would be 45-deg, touching the left/right would be 180-deg etc.

Note that you’ll need at least 5.1.1p2 (released 26th June) for this property to appear.
