I use first person controller to shot a ball, it can work when I test it
but after I complete build. it can’t throw the ball
I used unity 5.5.1 to edit and build it
the link below is the alert message.
The first image you posted are just “obsolete” warnings. Those can be calmly ingored
But this last image you posted is more revealing.
It says you’re missing audio refenrence, not court reference.
So start checking tags on audio gameobject and confirm that it still exists (if you switched scene).
