Convert string to float

Hi to all, i would like to know how to convert a string that contain a Mathf functions (ex : Mathf.Sin(Mathf.Pow(1, 2.0) + Mathf.Pow(2, 2.0))) to Javascript language, without incurring in this error :

"FormatException : Unknown char: M"

P. S = i have tried with : "float.Parse()".

Thanks.

 

Are you trying to convert a formula string into a float?

so "Mathf.Sin(Mathf.Pow(1, 2.0) + Mathf.Pow(2, 2.0)))" would result in say 8 or whatever the result is?

 

If you're trying to run that string as code, you need to use eval().

How does it work???
I searched for the eval function and found a massive wall of forum posts / QA posts that are saying its not possible because C# is a complied language and not a interpreter one.

If it works how?

 

Yes i tried it, but Unity give me this error :


UnityScript.Scripting.IEvalutationDomainProvider' interface member implementation must be public or explicit

My intention is that write more formulas like that in my first comment, and convert these to float (ex : graph.tk), but without convert string into JS i can't make this.

 

Ok guys, i have resolved eval() error, with delete all scripts contain "#pragma strict"

Thanks for help

 

It's a Unityscript feature, not C#. It works by recompiling the code on the fly, so there's a noticeable pause when code is compiled the first time.

(And yes, it doesn't work with #pragma strict, which also means it doesn't work on iOS.)
