public class RayPick : MonoBehaviour {
public Material[] mats;
public Texture[] texs;
int i = 0;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if(Input.GetMouseButton(0))
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);//从摄像机发出到点击坐标的射线
RaycastHit hitInfo;
if(Input.touchCount==1&&Input.GetTouch(0).phase==TouchPhase.Began){
if(Physics.Raycast(ray,out hitInfo))
{
Debug.DrawLine(ray.origin,hitInfo.point);//划出射线，只有在scene视图中才能看到
GameObject gameObj = hitInfo.collider.gameObject;
//gameObj.transform.parent.renderer.material = mats<i>;//设置父组件的材质
if(Input.GetTouch(0).tapCount==2){
gameObj.renderer.material.mainTexture = texs[i];
}
//gameObj.renderer.material = mats<i>;
//gameObj.transform.parent.gameObject.SetActive(true);
// other gameobjects set false
//checkIfPicked(gameObj.transform.parent.gameObject);
Debug.Log("---->"+gameObj.transform.parent.gameObject.name);
i++;
if(i>=mats.Length-1){
i=0;
}
Debug.Log("click object name is " + gameObj.name);
if(gameObj.tag == "boot")//当射线碰撞目标为boot类型的物品 ，执行拾取操作
{
Debug.Log("pick up!");
}
}
}
}
}
}
单击、双击、长按等：if(Physics.Raycast(ray,out hitInfo))
这个接下来触发的事件就是单击和长按。
复制代码
if(Input.touchCount == 1){
Touch touch = Input.GetTouch(0);
if(touch.phase == TouchPhase.Began){
newTouch = true;
touchTime = Time.time;
}else if(touch.phase == TouchPhase.Stationary){
if(newTouch==true&&Time.time-touchTime>1){
Debug.Log("longpress!!!");
newTouch = false;
longPressDetected = true;
//touched_model_name = "long press!!!!!!!";
}else if(newTouch==false&&longPressDetected== false){
newTouch = true;
touchTime = Time.time;
Debug.Log("TouchTime = "+touchTime);
}
}else{
newTouch = false;
longPressDetected = false;
Debug.Log("setting newTouch false");
}
}
双击：if(Input.GetTouch(0).tapCount==2)
判断单击的次数，如果为2，就是代表双击。
复制代码
if(Physics.Raycast(ray,out hitInfo))
{
Debug.DrawLine(ray.origin,hitInfo.point);//划出射线，只有在scene视图中才能看到
GameObject gameObj = hitInfo.collider.gameObject;
//gameObj.transform.parent.renderer.material = mats<i>;//设置父组件的材质
if(Input.GetTouch(0).tapCount==2){
gameObj.renderer.material.mainTexture = texs[i];
}
}</i></i>
