这是一段拖动物体的代码,比较简洁明了,对了解unity3d脚本概念有些帮助!在此加上注释分享! var mouseOverColor = Color.blue; //声明变量为蓝色 private var originalColor : Color; //声明变量存储本来颜色 function Start () { originalColor = renderer.sharedMaterial.color; //开始时得到物体本来着色 } function OnMouseEnter () { renderer.material.color = mouseOverColor; //当鼠标滑过时改变物体颜色为蓝色 } function OnMouseExit () { renderer.material.color = originalColor; //当鼠标滑出时恢复物体本来颜色 } function OnMouseDown () { var screenSpace = Camera.main.WorldToScreenPoint(transform.position); //三维物体坐标转屏幕坐标 //将鼠标屏幕坐标转为三维坐标,再算出物体位置与鼠标之间的距离 var offset = transform.position - Camera.main.ScreenToWorldPoint(Vector3(Input.mousePosition.x, Input.mousePosition.y, screenSpace.z)); print( "down" ); while (Input.GetMouseButton(0)) { //print("button0"); var curScreenSpace = Vector3(Input.mousePosition.x, Input.mousePosition.y, screenSpace.z); var curPosition = Camera.main.ScreenToWorldPoint(curScreenSpace) + offset; transform.position = curPosition; yield ; //这个很重要,循环执行 } } |
