Welcome to Unity. =)
That line means there's an error in one of your scripts.
It will help us if you copy and paste the script that you added in here.
That way, we can see what went wrong with your script and thus help you. =)
*Use the edit to edit your own post and add in the script.
It means you have errors in one or more of your scripts in your project.
In the status bar at the bottom of the Unity Editor it will tell you what the error is, in what file and and at what line. You can click that or open your console (ctrl + shift + c on PC, cmd + shift + c on Mac) to see a list of all the errors.
You need to sort all those out before it will run.
there is some error in your script.which you have wrote.it is telling to fix the error in the script before you play. or run the application.
double click on the error show.and fix it first
You should load recent sample that doesn't contain errors, and specifically adjusted to run on Unity version that you use.
Try download c# samples from asset store. Then you can playing with the others.
