Nodes:

• Script Function Node
• Expression Node
• Try Except Node
• Multi Execute
• Loop While

Script Function Node

This node allows to run a custom python Function from a script, and receive the return results.

If Use Keyword Arguments is checked, the function uses keyword arguments, otherwise positional arguments.

Initialization

To allow usage of Script Functions, the Script file containing python functions must first be loaded.

When changes are made, the script must be reloaded.

# addon.py
def combine_strings(string1, string2):
    return string1 + string2

Executing Custom Function

• string1 and string2 are the function parameter inputs, naming must match, position doesn't have to match
• output is the return value of function, can be named anything

Executing Custom Function without Keyword Arguments

• first and second are the function paremeter inputs, but naming doesn't have to match, position matters

Multiple Outputs

# addon.py
def swap_input(string1, string2):
    return string2, string1

Multiple outputs can either be combined, or split into separate outputs.

Expression Node

This node allows you to define a python expression, or execute the python expression (to preserve current state).

Altering inputs

Using libraries

In order to use other libraries that require to be imported, the import first must be executed. Then the library can be used anywhere in the addon.

Combining Expressions

Expression nodes can be combined to improve readability.

Try Except

Adds support for Python's try except statement.

Print Errors will print the error to the console, if an error occurs.

Multi Execute

Very straight-forward node, allows combining multiple input and output Execute sockets together.

Each of the connected inputs will execute all of the outputs.

Loop While

Adds support for Python's while loop.

Be careful, as this very well may crash your file, if you're not sure what you're doing.
