Does Javascript support conditional compilation

Unity Engine
1

I want to use a construct like this C# sample:

#if UNITY_IPHONE

// Get input using iPhone accellerometer

#endif

BUT I’d like to do it in Javascript. It does not work.

Does Javascript support conditional compilation ? If so does anyone know the syntax ?

Compiler directives do not exist in Unity
Not in JS nor in C# actually unless they were added with 2.5

I should say at least it would be new to me as this is a commonly asked question.

Its one of two common features from .NET that are not usable in unity (the other feature is namespaces which are also a no go within unity scripts)

There is a thread:
http://forum.unity3d.com/viewtopic.php?t=15650&highlight=ifdef

Than indicates it works in C#, and I did a quick test in a C# script and it seems to work - at least the script compiles with no errors.

Me too…one for the wishlist. :wink:

I did a quick test in Unity 2.5 and Unity 2.1 and Unity iPhone 1.0.1 and the syntax compiles under C# (I didn’t test if its actually working just that #if … #endif can be in a script and it compiles with no errors).

I raised an enhancement request via the Help->Report a problem (FogBugz) so maybe something will happen for Javascript:

The workaround, perhaps obviously, is to re-code my input handler in C#.
