3D-cursor location property

context.scene.cursor_location |
in Blender 2.8 API moved to “cursor” object

context.scene.cursor.location |
When trying to get the cursor location through the “context.scene.cursor_location” Blender throws an error:
‘Scene’ object has no attribute ‘cursor_location’
When developing add-ons it is often necessary to give an ability to set a number of parameters that affect the whole add-on work to the user. For example, the user can specify a directory for saving/loading files, set some default variables or switch between add-on modes. Of course, the interface for setting such parameters can be placed in the add-on panel, but it is better to place it in a separate add-on preferences panel, which is located in the “Preferences” window under the add-on installation panel.
The main advantage of the add-on preferences is that they don’t reset when Blender restarts. The user does not need to configure the add-on preferences each time, it’s enough to set the necessary parameters once, personalizing the add-on for convenient work.
Let’s create an add-on and define a parameter, placing it in the add-on preferences panel.
In Blender 2.7 the “*” (star) operator is used in the matrix, vector, and quaternion multiplication. In Blender 2.8 it is replaced with the “@” (at) operator.
If the “*” operator is used in vector, matrix or quaternion multiplication in Blender 2.8 it throws an error:
Element-wise multiplication: not supported between ‘Matrix’ and ‘Matrix’ types
Proper use of the “@” operator:
