GUI展开动画效果

奔跑的小兔

只接来代码：

var show = false;
var grow = false;
var min = 0.0;
var max = 50.0;
var height = 0.0;
var speed = 0.0;
//var skin:GUISkin;
function OnGUI ()
{
//GUI.skin = skin;
if(GUI.Button(Rect(5,5,104,25),"List"))
{
   grow = true;
   if(!show)
   show = true;
}
if(show)
{
   GUILayout.BeginArea(Rect(7,30,100,height),"","Box");
   GUILayout.BeginVertical();
   for(i = 0;i<18;i++)
   GUILayout.Button(i+".Title");
   GUILayout.EndVertical();
   GUILayout.EndArea();
}
if(grow)
{
   speed += Time.deltaTime*5.0;
   height = Mathf.Lerp(min,max,speed);
   if(Mathf.Approximately(height,max))
   {
    grow = false;
    max = min;
    min = height;
    speed = 0.0;
    if(min == 0)
    show = false;
   }
}
}
