鼠标拾取代码总结 - 纳金网

function Update ()
{
if (Input.GetMouseButton (0))
{
var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
var hit : RaycastHit;
if (Physics.Raycast (ray, hit))
{
Debug.DrawLine (ray.origin, hit.point);
print(hit.collider.gameObject.name);
}
}
}
************************************************************************
c#代码会有些不同
转换成c#代码如下
首先定义 public RaycastHit hit;
if (Input.GetMouseButton (0))
{
Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
****************************************************************
Assets/scripts/SelectTarget.cs(26,21): error CS1502: The best overloaded method match for `UnityEngine.Physics.Raycast(UnityEngine.Ray, out UnityEngine.RaycastHit)' has some invalid arguments
Assets/scripts/SelectTarget.cs(26,21): error CS1620: Argument `#2' is missing `out' modifier
****************************************************************
if (Physics.Raycast (ray, out hit)) //注意这个地方与javascript不同，需要加OUT不然会报错，错误如******之间的提示
{
Debug.DrawLine (ray.origin, hit.point);
}
if(hit.collider.gameObject.name==“所要点击的物体名称”)
{
Debug.Log(“选中了”+hit.collider.gameObject.name);
// *************执行什么操作代码放这即可
*************************比如让选中的物体颜色变为红色
GameObject b = Gameobject.Find(hit.collider.gameObject.name);
b.renderer.material.color = Color.red; //比如将颜色变为红色
}
}
