hi there guys I am currently making an app in unity where the user can type a math formula into a text box and it will imply certain behaviour on objects. I'm using the javascript eval to parse the user math expression. My question is this, how can I include a variable into this formula. For example if the code is like this: Code (csharp): var x = 2; var userExpression = "x*x+x"; var y = eval(userExpression); Thanks in advance
