Extract object properties from animation for each frame

I am an absolute beginner, please forgive me if this is a basic question. I am using Blender 2.91.

So I have n objects one in the middle and others surrounding it and the one in the middle is the parent of everything else. I am rotating the middle one using keyframes that results in the others revolving around it. Now I am playing it using python and have a handler for frame change. Here I want to extract object properties like location and position of each object for each frame.

Currently I am using obj.rotation_euler and obj.location to fetch the properties, but I get same values for all frames. (I am doing this inside the handler, so I presume it has the current frame properties in the ‘scene’ param?)

So can you please tell me how to extract these properties per frame.
Note, I need to do some mathematical calculation with the values , if that makes any difference.

Will be grateful for any help.

On mobile so i can not explain in detail but for parented objects use

matrix_world.to_rotation (i think)

Thanks!! [email protected] worked for me! :slight_smile:
