Your first iClone Python Plugin

This topic will guide you through the creation and execution of your first iClone Python plugin.

Setup Your Environment - Prepare your Python IDE

iClone doesn't support an internal IDE, so you'll have to resort to an external script editor like Notepad++, PyCharm, Spyder, among others.

We recommend Notepad++, it's a free and tiny source code editor with Python support. Before using Notepad++, you should enable Replace by space option under Settings > Preferences > Language > Tab Settings.

Make sure that tab sizes are set to exactly 4 spaces.

Loading your Python Plugin

There are two different methods for loading a plugin into iClone:

Method 1: Create a file and put it inside the iClone Install Directory \ Bin64 \ OpenPlugin folder\ [Your Plugin Name] The PY files requires one specific functions: initializePlugin(), which is respectively called when iClone attempts to load the plugin. If this functions do not exist in the file, the plug-in will fail to load. And remember the name of PY file must be

import RLPy
import PySide2
from PySide2 import *
from PySide2.shiboken2 import wrapInstance

def initialize_plugin():
    # Add menu
    ic_dlg = wrapInstance(int(RLPy.RUi.GetMainWindow()), QtWidgets.QMainWindow)
    plugin_menu = ic_dlg.menuBar().findChild(QtWidgets.QMenu, "pysample_menu")
    if (plugin_menu == None):
        plugin_menu = wrapInstance(int(RLPy.RUi.AddMenu("Python Samples", RLPy.EMenu_Plugins)), QtWidgets.QMenu)

    hello_world_action = plugin_menu.addAction("Hello World")

def show_dialog():
    RLPy.RUi.ShowMessageBox("Your First Python Plugin", "Hello World", RLPy.EMsgButton_Ok)

Method 2: Manually perform Menu > Script > Load Python, choose a PY file then make sure the initial define resembles the following:

import RLPy
def run_script():
    print ("Hello World")
    RLPy.RUi.ShowMessageBox("Your First Python Plugin", "Hello World", RLPy.EMsgButton_Ok)
