Blender插件编写指南

前言

Blender插件是Blender的利器, 用户可以使用各种插件扩充Blender的功能.

Blender Python插件以bpy.props, bpy.types.Operator, bpy.types.Panel, bpy.types.UILayout, (...)为基础, 通过用户自定义包来实现.

插件要点

  1. 定义操作器
  2. 定义操作器控制面板(或菜单)
  3. 注册/注销操作器和面板

简单实例

bl_info = {
    "name": "Move X Axis",
    "category": "Object",
}

import bpy


class ObjectMoveX(bpy.types.Operator):
    """My Object Moving Script"""      # blender will use this as a tooltip for menu items and buttons.
    bl_idname = "object.move_x"        # unique identifier for buttons and menu items to reference.
    bl_label = "Move X by One"         # display name in the interface.
    bl_options = {'REGISTER', 'UNDO'}  # enable undo for the operator.

    def execute(self, context):        # execute() is called by blender when running the operator.

        # The original script
        scene = context.scene
        for obj in scene.objects:
            obj.location.x += 1.0

        return {'FINISHED'}            # this lets blender know the operator finished successfully.

def register():
    bpy.utils.register_class(ObjectMoveX)


def unregister():
    bpy.utils.unregister_class(ObjectMoveX)


# This allows you to run the script directly from blenders text editor
# to test the addon without having to install it.
if __name__ == "__main__":
    register()
