I have two scripts. One is in javascript, the other in C#. The C# script has a variable called “a”. How do I find the value of that variable to use it in my javascript script?
Make the variable in your C# script public or use a property to return it.
The real question you want to ask is how to make your C# script visible in JavaScript.
With that you need to look at the unity script building order :

The script with the variable you are trying to access should be in a folder called “Standard Assets” or “Plugins” so you ensure the right script gets compiled first.
