Start Blender and switch to the Scripting workspace.Ĭlick the New button in the text editor to create a new text data-block.Ĭopy the code from above and paste it into the text editor.Ĭlick on the “Simple Operator” item found in search. Once this script runs, SimpleOperator is registered with BlenderĪnd can be called from Operator Search or added to the toolbar. remove ( menu_func ) if _name_ = "_main_" : register () # test call bpy. append ( menu_func ) def unregister (): bpy. bl_label ) # Register and add to the "object" menu (required to also use F3 search "Simple Object Operator" for quick access). new ( "MyTestCollection" ) collection = def menu_func ( self, context ): self. get ( "test_prop", "fallback value" ) # dictionaries can be assigned as long as they only use basic types. object : print ( "Property found" ) # Use the get function like a Python dictionary # which can have a fallback value. It gives access to library data, for example:īpy. This implies that any setting that can be changed via a button can also be changed with Python.Īccessing data from the currently loaded blend-file is done with the module bpy.data. You can access Blender’s data with the Python API in the same way as the animation system or user interface Key Concepts Data Access Accessing Data-Blocks Scripts can also run from the command line with Blender but to learn scripting in Blender this isn’t essential. The Python Console is typically used for typing in snippets and for testing to get immediate feedback,īut can also have entire scripts pasted into it. py files or paste then from the clipboard, then test using Run Script. You can use the Scripting workspace accessible from the Topbar tabs.įrom the text editor you can open. Rather than manually configuring your spaces for Python development, Text editor or entering commands in the Python console.īoth the Text Editor and Python Console are space types you can select from the header. The two most common ways to execute Python scripts are using the built-in Scripts/startup/bl_operators for operators. Scripts/startup/bl_ui for the user interface. To examine further scripts distributed with Blender, see: Many python examples can be found in the text editor’s template menu. The context menu of buttons directly links to this API documentation (when enabled see above). Is great for testing one-liners it has autocompletion so you can inspect the API quickly.īutton tooltips show Python attributes and operator names (when enabled see above). This document its intended to familiarize you with Blender Python APIĪ quick list of helpful things to know before starting: Subscribe to changes to data and it’s properties.ĭefine new settings in existing Blender data. Modify user preferences, keymaps and themes.Ĭreate user interface elements such as menus, headers and panels.Ĭreate new rendering engines that integrate with Blender. Change Log: List of changes since last Blender releaseīut some areas are still being extended and improved.Įdit any data the user interface can (Scenes, Meshes, Particles etc.).Gotcha's: Some of the problems you may encounter when writing scripts.Tips and Tricks: Hints to help you while writing scripts for Blender.
