鼠标的双击

function
OnGUI(){ 
    if(Event.current.isMouse
&& Event.current.type == EventType.MouseDown && Event.current.clickCount == 2){ 
        print("double
click"); 
    } 
}

上面是双击屏幕的事件，假如想双击某个物体

var b = false; 
function
OnGUI(){ 
    if(Event.current.isMouse
&& Event.current.type == EventType.MouseDown && Event.current.clickCount == 2){ 
        if(b){ 
            print("double
click " + transform.name); 
        } 
    } 
} 
function
OnMouseEnter(){ 
    b
= true; 
} 
function
OnMouseExit(){ 
    b
=false; 
}

意思就是，当鼠标进入你想点击的物体后，双击才有效果，否则鼠标未进入物体，或者exit时，b = false，双击无效果。 


移动设备上触屏的双击

var t1:double; 
private
var t2:double; 
function
Update(){ 
    if(Input.GetMouseButtonDown(0)){ 
        t2
= Time.realtimeSinceStartup; 
        if(t2
- t1 < 0.2){ 
            print("double
click"); 
        } 
        t1
= t2; 
    } 
}

移动端GetMouseButtonDown是有效果的，所以这样利用t1，t2,记录两次单击的时间间隔，假如小于0.2s，则被判断为双击。 


同样，移动端点击某一确定物体的双击事件

var t1:double; 
private
var t2:double; 
public
var cam:Camera; 
function
Update(){ 
    if(Input.GetMouseButtonDown(0)){ 
        var
ray:Ray = cam.ScreenPointToRay(Input.mousePosition); 
        var
hit:RaycastHit; 
        if(Physics.Raycast(ray,hit)){ 
            if(hit.transform.name
== gameObject.transform.name){ 
                t2
= Time.realtimeSinceStartup; 
                if(t2
- t1 < 0.2){ 
                    print("double
click " + transform.name); 
                } 
                t1
= t2; 
            } 
        } 
    } 
}

对于上面t1和t2可以定义为System.DateTime类型，这样t2 = System.DateTime.Now;相减后用TimeSpan.如下：

var t1:System.DateTime; 
private
var t2:System.DateTime; 
public
var cam:Camera; 
function
Update(){ 
    if(Input.GetMouseButtonDown(0)){ 
        var
ray:Ray = cam.ScreenPointToRay(Input.mousePosition); 
        var
hit:RaycastHit; 
        if(Physics.Raycast(ray,hit)){ 
            if(hit.transform.name
== gameObject.transform.name){ 
                t2
= System.DateTime.Now; 
                if(t2
- t1 < System.TimeSpan(0,0,0,0,200)){ 
                    print("double
click " + transform.name); 
                } 
                t1
= t2; 
            } 
        } 
    } 
}

最后是，关于GUI的双击，原理都类似：

        t

        if(b){ 
            print("it's

            b

        }else{ 
            b

        } 
    }

function

    if(t
+ 0.2 < Time.time){ 
        b
= false; 
    } 
}
