(Android) Pick up objects with the cross from the centerof the screen

This time i will be more specific. :smiley:
I need a script for Android to pick up objects with a tag when i (onMouseDown) a GUI Texture.
But i want to pick up the object what is in the front of my Cross from the center of the screen(see in screenshot)
[33086-screenshot+cross.png|33086]

I use the Joystick script and the FirstPersonControl script from Standard Assets(Mobile).
I want to can look at a object with the cross, and when i press a button, to pick it up.When i press another button to leave it to fall.The objects have the tag: “pick” and it have colliders and RigidBody Components.Please Help.

If it’s simply a cross from the middle of the screen, is there any reason you can’t fire a short-range raycast from the center of the screen (Screen.width * 0.5 and Screen.height * 0.5) and see if it hits something nearby enough to pick it up?

Then, since they have rigidbodies, you could simply get a distance to the object on the initial grab, then apply physics force to push it towards a point that distance in front of you.
