Question

Hi folks!

I'v a function than create a sphere over a plane on the hitpoint of the mouse cursor when I press the left button of the mouse.

I want to make the object growing while the mouse button is pressend, and stop growing when I release the mouse.

I'm trying to do that with Input.GetMouseButtonUp and Down without success :(

Here is my actual code

    var bomb : GameObject;
var timeD : float;
var drop : GameObject;


function Update (){



    var hit : RaycastHit = new RaycastHit();
    var cameraRay : Ray  = Camera.main.ScreenPointToRay(Input.mousePosition);


    if (Physics.Raycast (cameraRay.origin,cameraRay.direction,hit, 1000)) {
        var cursorOn = true;
    }

    var mouseReleased : boolean = false;

    //BOMB DROPPING 
    if (Input.GetMouseButtonDown(0)) {

        drop = Instantiate(bomb, transform.position, Quaternion.identity);
        drop.transform.position = hit.point;

        Resize();

    }
}

function Resize(){
    if (!Input.GetMouseButtonUp(0)){

            drop.transform.localScale = Vector3(timeD,timeD,timeD);
            timeD +=Time.deltaTime;
        }
}

Tnx!!

A few things, you'll probably want something more like:

drop.transform.localScale += Vector3(Time.deltaTime, Time.deltaTime, Time.deltaTime);

And you'll want this to happen over course of many calls to Update:

function Update (){
    if(Input.GetMouseButton(0)) {
        // This means the left mouse button is currently down, so we'll augment the scale
        drop.transform.localScale += Vector3(Time.deltaTime, Time.deltaTime, Time.deltaTime);
    }
}

GetMouseButtonUp and GetMouseButtonDown only get called once.. just on the frames those events take place.

You probably want to define a 'speed' so you can adjust that var speed = .5; drop.transform.localScale += Vector3(Time.deltaTime, Time.deltaTime, Time.deltaTime) * speed;
