[[Solved] check if mod is loaded]

how would i check if a mod is loaded like say i have BuildCraft installed i want to check if that mod is loaded then if it is use stuff from the mod

 

String mod = "NotEnoughItems";

                if(Loader.isModLoaded(mod)){} I use this to check that is nei loaded. It works fine 4 me. Just replace the string with Buildcraft. Ui: I use this code in my client proxy
