Currently have a script that generates a level using 3d mesh to create hills for a side scroller game that follows the camera.

I would like to work on this script and get help on how to convert it to a 2d level generator using sprites and 2d polygon colliders.

If you use a 2DCollider player it will go through the level because its 3D collider.

How time worthy does the conversion look?

Thanks
