Hello, thank you very much for your message, we probably understand part of your needs。
Regarding the left/right movement, if you are referring to the coordinates of the control, then you can use the set_x/y directive to set them after getting the return value of the pair by setting the relevant return value of the button.
But taking into account that there may be part of our understanding of the problem of bias, can you combine some of the illustrations to give us more detailed information so that we can more clearly explain your needs, (only need a simple approximate style + part of the key to the description can be). Thank you for your cooperation and look forward to your reply.
Best Regards,
Zhang Su
