[游戏开发]Blender 插件开发 添加约束

一个简单的功能,相机一直对准物体,不管物体怎么移动,用blender做过这功能的都知道只要添加一个阻尼跟踪就好了

代码

    def execute(self, context):
        camera = None
        for obj in bpy.context.collection.all_objects:
            if obj.type == 'CAMERA':
                camera = obj
                break
        if camera is None:
            return {'FINISHED'}
        parent_object = None
        if '酒瓶' in bpy.context.collection.all_objects:
            parent_object = bpy.context.collection.all_objects['酒瓶']
        if parent_object is None:
            return {'FINISHED'}
        constraint = camera.constraints.new('DAMPED_TRACK')
        constraint.target = parent_object
        constraint.track_axis = 'TRACK_NEGATIVE_Z'
        return {'FINISHED'}

?下次写个相机绕着物体旋转的功能,把前边写的功能给用上,算做一个总结
