| However, if you want to call a global function, i.e. one that is outside of the map or entity class, then you can use the prefix ''$''. For example: ''SomeFunction(…, "$CallbackFuncDecl")''. Note that this class must be in the same file (or in one of the included files) as the class objects that would otherwise have been searched. So if you do ''$SomeFunc'' for a callback that checks the map file normally, then this will call the global func ''void SomeFunc()'' in the map script or in a file included by the map script. | However, if you want to call a global function, i.e. one that is outside of the map or entity class, then you can use the prefix ''$''.
