How does it work, taking pieces from T_TappyChicken_UI_01 ?

Hello guys,

I never developed games before but the Tappy Chicken’s open blueprint inspired me to try, so I am doing this this January and I am almost done with my game part. Now I want to change the title and score board design, but can’t figure out how you read coordinates from the T_TappyChicken_UI_01 to animate pieces. When I tried to simply exchange the image, my own title’s box got cut off as the Tappy Chicken’s title design, and I realize that I don’t know how those meshes were created and how I can change it. Would you please explain? I will appreciate this.
