BCE0005: Unknown identifier: 'MouseLook'

Given your error code, I know you're in a JS script.

Last I knew, MouseLook is written in C#.

You can reference C# code from a JS file, but only if it was compiled earlier. Your script worked before because MouseLook was in Standard Assets, which gets compiled before the rest of your scripts.

I'm having the same error. What does this mean,"You can reference C# code from a JS file, but only if it was compiled earlier."

How do you compile a C# code before you can use it in a javascript? I ask because I'm just starting out learning how to script.

in the http://docs.unity3d.com/412/Documentation/ScriptReference/index.Script_compilation_28Advanced29.html

It says<" All scripts that are compiled in this step have access to all scripts in the first group ("Standard Assets", "Pro Standard Assets" or "Plugins"). This allows you to let different scripting languages interoperate. For example, if you want to create a Javascript that uses a C# script: place the C# script in the "Standard Assets" folder and the Javascript outside of the "Standard Assets" folder. The Javascript can now reference the C# script directly.

Scripts that are placed in the first group, will take longer to compile, since when they are compiled the third group needs to be recompiled too. Thus if you want to reduce compile times, put scripts that seldom change into group 1 and scripts that change a lot into group 3. "

But, I do not understand this solution. How do you place the C# script in the "Standard Assets" folder and the Javascript outside of the "Standard Assets" folder?
