So, when the compiler finds a problem with your code it emits 4 pieces of information:
a) An error number
b) The line number where the problem happened
c) The column where the problem happened
d) A textual description of the error.
New scripters tend to only focus on the (d). That textual description can be a little misleading, so I’d recommend:
Double-click on the error, which should take you to the line in the script with the problem. If that doesn’t work, simple switch to your text editor and find the line number. It’s the one after the opening bracket.
Review the code, and see if you can find any problems. It can happen that the line that gets reported is after where the real problem happened. So you should look at the specific line, and lines before.
Visit Answers and search for the error number. There are many thousand of questions about the many error numbers. For example, I believe your error number is cs0119. Searching for that on Answers gives you:
If you look at the number of views those pages have, you’ll see that around 100,000 people have used Answers for help with this error. So it’s pretty usual to use that site for help.
Haha it looks like you have no idea as to what you’re doing. I highly suggest you to watch the tutorials made my Unity and refer to the Unity documentation.
