Synchronizes creation of the given node on all Slaves. This method is to be called after node creation on the Master.Notice

Loads a world from the specified file on the Master and all Slaves. Syncker is able to automatically synchronize the current world, but it works as follows: Slaves shall only start loading a new world after it is completely loaded on the Master.

Return value
Number of the last added callback of the specified type, if the callback was added successfully; otherwise, -1.bool removeCallback ( CALLBACK_INDEX callback, Variable func ) #
