Ran into an interesting problem while trying to compile a Unity project for iOS. It failed to build because
“LocationService class is used but Locations Usage Description is empty. App will not work on iOS 10+. UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)”
Well as far as I know there is not anything calling or requesting location services. I probably could have just put a reason for requesting the service under the build options in Project Settings. But why “use” something we don’t need?
Using the handy grep tool from a terminal, I was able to search through the project for “LocationService” and that returned a couple hits for files in the PlayMaker folder.
Looks like PlayMaker has a couple preconfigured “scripts” for Starting, Stopping, and Requesting Location.
Deleting the following four C# files resolved the error and it built fine afterwards.
Problem: When changing the shader color on a game object, the color on other game objects changes.
Reason: This happens because the other game objects are using the same Mesh Renderer as the game object your modifying. So when your changing the shader, your actually modifying the Mesh Renderer, not the game object.
Fix: Change the Mesh Renderer for the game object.
In the example picture below, when you change the color on the cube (highlighted red) the color on the capsule changes, because they both are using the same Mesh Renderer (highlighted green). To fix, change either the Cube or Capsule to a different Mesh Renderer (highlighted green)
