Tutorial: Space Shooter - Mesh Collider doesn't display

Questions & Answers
1

I’m following along with the Space Shooter tutorial. In the part where we experiment with a Capsule Collider, the collider lines show fine in the scene. When I add the Mesh Collider, I’m not told by Unity that it will remove the Capsule Collider. I instead have to remove it manually. It was going to let me have both.

Then, with the Mesh in the Mesh Collider set to the “player_ship_collider”, the green collider lines do not show at all in the scene. Regardless of if the Mesh Renderer is enabled or not and regardless of zoom level.

My questions are:

  1. Is it a bug that Unity was going to allow me to have a Capsule and Mesh Collider for the Player object?

  2. Did the Player’s Mesh Collider simply become corrupt on the import? Apparently it was created in an older version. (EDIT) I see now that in 5.0 that “Convex” must also be selected.

  1. You’re always allowed to have multiple colliders on one GameObject. New since Unity 4 is the usage of several colliders of the same type, but using different once worked since 3.x or even longer.
  2. If you try any of the other mesh colliders Unity is shipped with, the mesh collider component is folded out and you can then see the green lines, the FBX is indeed corrupted.
  3. MeshRenderer has nothing to do with the green mesh lines being rendered (since they’re only visible in the scene view)
