VR google cardboard distance adjustment

Hi Its VR google cardboard App for Android in Unity 2017. I have 3 trees. Apple, Orange, and Cherries. Need to point with white dot until a dot becomes a circle. When the dot becomes the circle tap on screen and Orange attaches to camera and with left mouse press and "alt" move to basket. Basket has collider. When the Orange hit the collider it put the Orange in basket in the place of array called ArrayList. I need possibility to take the Orange or Apple from basket and put it on the ground. I need you will write Document what you have done. Rest of details I'll give in chat.
