创建游戏对象的副本

Question

在 Unity3D 中如何通过单击鼠标创建对象的副本？

另外，如何在运行时选择要克隆的对象？（最好选择鼠标）。

Answer 1

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(Time.deltaTime, Time.deltaTime,
                                                 Time.deltaTime);
            timeD +=Time.deltaTime;
     }
}

您会希望在多次调用 Update 的过程中发生这种情况：

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);
    }
}
