Unity 2D OnCollisionStay2D bug found?

[dbanfield]

Hi,
I'm pretty sure I found a bug in the new unity 2d collision system. Posting here first though to clarify, as I found it using the 2d toolkit tile map system.

To reproduce:

• Open up the attached project
• press play
• Debug lines will indicate that the player is currently on a vertical normal
• press the left key to walk up against the wall on the left. Stop there.
• hold down space for a short while
• the debug lines will stop - obviously, you are off the ground 
• when you land again, still no debug lines
• walk a little to the right, continue walking on this chunk, still no vertical normal. Huh?
• With further debugging you will find there are no registered contact points with a vertical normal. This is surely incorrect since you are quite clearly standing on the platform

If you could please take a look and clarify whether or not I'm missing some blindingly obvious thing, but it seems pretty clear cut. If there is a problem, can file a bug with unity.

Thanks
Dan

Yup, that looks very clear cut. If you were going to submit this to Unity, I strongly recommend removing all the tk2d stuff so they don't try to shift the blame - I've tried it, you can reproduce this with a box and a hand drawn edge collider in the same L shape you have there.

Thanks for the confirmation. Took your advice and modified the project to not include 2dtoolkit. Bug submitted - was expecting a confirmation email with a link to the issue as the FAQ describes but nothing yet. Will post it here when it comes through in case anyone's interested.
