I would like to move a 2D Sprite image when user drag their finger to a position.
I have used the templates, it allow me to move the 2D image, however, the picture size reduce when I move up, and the size increase when I move down, since it is in a 3D space.
How can I simply transform the position of a 2D Sprite by detecting user's finger and update the picture to the finger position? Thank you.
Second, I saw an Official Snapchat App being able to detect user's hand. When the hand is detected, a heart will stick to the hand. When the hand lost detection, the heart will blow away and disappear.
I want to be able to do something similar. I want to attach a 2D picture on user's hand when snapchat detects the hand.
How can I do that?
I tried to follow the new templete "Marker", and set the hand as a marker. However, the hand image is too simple to be used as a marker.
