Hi,
Something I'm getting confused about regarding tk2duiitems. I managed to get your ui demo working with a tk2d camera with the same orthographic size set for the camera and for the sprite collection (1). I could then hit the button easily.
Now I notice that if I want to do it by pixel per meters, the only way to find the correct dimensions for the collider is to create a box collider for the sprite and then copy it to the gameobject in the above hierarchy i.e. create a collider for the button graphic and then copy it to the parent object above. I was wondering if I missed something that can do that for me?
Thanks
