"Scripted" daemons are fully customizable, because they can be programmed to your individual needs. By default, they do not add forces or delete particles and their entire functionality is based on custom Python scripts. To use a "Scripted" daemon you first need to apply it as usual and then edit it. As already mentioned, the use of this type requires Python knowledge. The scripting compendium for RealFlow contains a comprehensive introduction to Python.
When you click on this button RealFlow opens a new scripting window with predefined functions. This window contains a set of basic functions that can be used to influence emitters, particles or rigid bodies.
The script editor and its features is described in the “RealFlow Scripting Guide” together with an introduction to Python scripting.
