Unity 中作为 SceneSwitcher 的 3d 对象

Question

I'm programming a mobile game for a school project and I need help. I want to switch a scene when I'm clicking on a 3d object. I know how to do it with mouse input, but with touch input, I have no clue. I tried it a lot, but I didn't find a solution. Can anyone help me or send me the link to a tutorial?

Answer 1

You can use Input.GetTouch to get touch information on the touch screen and then use RaycastHit to determine the selected object

1. Get touch informaton

Touch touch = Input.GetTouch(0);
if (touch.tapCount == 1)
{
    if (GetObjectTouchByTag(touch.position) != null)
        SceneManager.LoadScene("SampleScene"); // switch scene with name SampleScene
    // ...
}

2. Get 3D GameObject with RaycastHit

// Raycast object by with tag
public GameObject GetObjectTouchByTag(Vector3 position)
{
    Ray ray = Camera.main.ScreenPointToRay(position);
    RaycastHit[] raycastHits;
    raycastHits = Physics.RaycastAll(ray);
    foreach (RaycastHit hit in raycastHits)
    {
       if (hit.collider.gameObject.tag == "SampleObject")
       {
          return hit.collider.gameObject;
       }
    }
    return null;
}

Hope it can help you!
