Hello robxD321,
Welcome to the forum.
Probably you are looking for this:
You have to create those attribute-blocks yourself:
-go into design mode (it is default)
- Locate the Attributes tab on the right hand (between scene and game)
- [Create an Attribute...]
- name: dy and select number as its type
- Now you have a set dy to in the setters sub-tab
The screen looks like this if you followed the steps:
Hope this helps.
Best regards from
M.E.
