Programming/inspector question

You can create a prefab from your object. The prefab can then be used in each of your scenes. As long as you edit the prefab in the project window and not in the $$anonymous$$erarchy window, the changes you make will reflect in all your prefab instances. T$$anonymous$$s comes very handy if you have for example an prefab called "Score Meter" w$$anonymous$$ch you want to reuse in every scene. If you want to make changes to that meter for all instances just make the changes on one prefab itself. If you want to make level specific changes open the scene where the prefab instance is and edit the value you want to override on the instance itself.
