need help in creating logic
Hi all,
I need suggestion of all of you guys in approaching my goal. What i want to do is... I have a bow still at one place but can rotate at its pivot point and there is an arrow that is used to pull the thread of the bow, as i drag back the arrow then thread of the bow should pull and when drag furthur, bow's thread should lose.
Can anyone help me how can i approach this.. I have attached an image as a refrence here.
