Compliation settings?

Hello,

i’ve made a nice and simple project demonstrating the PC/Mac,WebPlayer and Mobile device navigation.

Since this code isn’t too big yet i can switch between the build platforms using Build Settings and commenting out the control code which the chosen platform doensn’t need. As this code grows larger with every feature, i would like to know if there’s a way i can immediately tell the compiler with one line of code like

Compile this for iOS/WebPlayer/PC and Mac Standalone

?

Check this out:

Application.platform returns an enum-type value representing the platform the build is currently running on.
