This quick start guide gives you an overview of RealFlow's Python scripting capabilities.

You will learn how to define and assign variables, work with different data types like integers or vectors, address RealFlow parameters, perform calculations, and manipulate individual particles.

A long list of example scripts help you to get started.

Available Python Commands

RealFlow provides an interface to the Python programming language. All RealFlow-specific Python commands are described in the SDK (Software Development Kit):

RealFlow > Help > Scripting Reference

There you will find a long list of classes and each class has its own, specific set of commands.

Variable Names

When you assign names to variables you should only use the following characters:

• A-Z, a-z, 0-9, and the underscore _
• Avoid special characters like ä, É, ∂, §, ß, etc.
• If you want to separate a variables name use the underscore, e.g. gravity_strength.
• Never use blanks, colons, or dots!
• Python is case-sensitive and there is a difference between emitter_resolution and Emitter_Resolution.

Leading Spaces and Indents

Python code is structured through leading spaces and indents. For obvious reasons they are the most common source of syntax errors.

The first code example prints out a syntax error, the second one works:

sceneObjects = scene.getObjects()
for singleObject in sceneObjects:
scene.message(singleObject.getName())

And here the working code:

sceneObjects = scene.getObjects()
for singleObject in sceneObjects:
	scene.message(singleObject.getName())
