How to Set position along with mousePosition

Questions & Answers
1

hello, i'm okay with the "ScreenToWorldPoint" error, but i am now moving the player depending on where the mouse position is.... and it works, he moves when the mouse moves, but he keeps resetting to the same "drag start" and i want each "drag start" to be where the current transform.position is, but i don't know how to do that... could someoen help me please?

EDIT: the COMPLETE script works... it's called FMoveAround, and the mouse "drag to move" kinda works: he moves exactly as i want, but he shifts from the place i want him, to some random place very far away, but the shifts are fast, kinda like a "every other frame he's where i want him to be" kind of thing.

here's my script: 

function Update() 
{     
 if(Input.GetKey(KeyCode.Mouse1))
{
 transform.position.z += (Input.mousePosition.x + transform.position.z);
 transform.position.y += (Input.mousePosition.y + transform.position.y); 
}

     print(Input.mousePosition);
}

any help is GREATLY apprecitaed! :)

Thank You very much!

If what you want to do is keep the player in the same position relative to the mouse as when you started holding down the button, then a much better way would be to have a Vector2 that records that offset and you can then maintain that offset in your assignment statements. A Vector2 because we are only storing 2 dimensions of offset. That is:

var offset : Vector2 = Vector2.zero;
function Update(){
    if(Input.getKey(KeyCode.Mouse1)){
        if(offset== Vector2.zero)
            offset = new Vector2(transform.position.z - Input.mousePosition.x, transform.position.y - Input.mousePosition.y);
        transform.position.z = mousePosition.x + offset.x;
        transform.position.y = mousePosition.y + offset.y;
    }
    if(Input.GetKeyUp(KeyCode.Mouse1)){
        offset = Vector2.zero;
    }
}
