问题
I have a canvas with Render Mode: Screen Space - Camera
Inside that I have square objects that I want collisions to be detected based off world view game objects. (Reason for this they need to scale based off device screen size)
I added a 2D box colliders to theses boxes but then get this error.
Error: this collider will not function with an effector until there is at least one enabled 2D effector on this GameObject
How can I detect Collisions of game objects in world view with tag "a" when they collide with my Canvas objects with tag "b"
