I’m new to unity so sorry if this is a dumb question:
My A* Gameobject has no size. On every tutorial I have seen there was small area in the scene view which could be dragged to the right size but I only have the green and red line if I select it with the resize tool.
Happens in my project an the example scenes.
I had this same issue just now - I clicked on the “Gizmos” tool in the top bar of the Scene view and that seemed to fix it! I think I clicked it once to disable them all, then again to re-enable and that seems to have fixed whatever happened.
