Unity Android 触摸不按预期工作

Question

我正在使用这个触摸脚本在触摸屏幕时显示一些效果：

var ParticleA : GameObject;
//var bulletHole : GameObject;

function Update () {

    var hit : RaycastHit;
    // Use Screen.height because many functions (like this one) start in the bottom left of the screen, while MousePosition starts in the top left
    var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);

    if (Input.GetMouseButtonDown(0)) 
    {
        if (Physics.Raycast (ray, hit, 200)) 
        {
            var newparA = Instantiate(ParticleA, hit.point, Quaternion.identity);
            //var hitRotation = Quaternion.FromToRotation(Vector3.up, hit.normal);
            //Instantiate(bulletHole, hit.point, hitRotation);
            Destroy(newparA, 12.0);
        }
    }
}

它不适用于 Android。触摸时，它只在中央屏幕显示效果，而不是我手指实际触摸的位置。

可能是什么问题？

Answer 1

您不想使用 Input.GetMouseButtonDown(0)（那是鼠标...正如其名称所示）。

使用Input.touches：http://docs.unity3d.com/Manual/MobileInput.html

Answer 2

试试这个

 var ParticleA : GameObject;

    function Update () 
    {
        var hit : RaycastHit;
        if (Input.GetMouseButtonDown(0)) 
            {
            if (Physics.Raycast (transform.position, Vector3.forward,out hit ))  
               {
                   var newparA =Instantiate(ParticleA, hit.point,Quaternion.identity );
               Destroy(newparA, 12.0);
               }

Answer 3

你可以试试这个：

var ParticleA：游戏对象；

函数更新(){

var 命中：RaycastHit；

for (var touch : Touch in Input.touches) {

    if (touch.phase == TouchPhase.Began) {

                            var ray = Camera.main.ScreenPointToRay (touch.position);

                            if (Physics.Raycast (ray, hit, 200))

       {

                                var newparA = Instantiate(ParticleA, hit.point, Quaternion.identity);

        Destroy(newparA, 12.0);

       }

    }

            }

}

此代码使用 C#。将此代码放入 UPDATE() 函数中。它将在 Unity 编辑器和 Android 平台上运行。

RaycastHit hit;
Ray ray;
public Camera hudCamera;


            if (Application.platform == RuntimePlatform.WindowsEditor) 
            {
                ray = hudCamera.ScreenPointToRay(Input.mousePosition);
                if (Input.GetMouseButtonDown(0))
                {
                    if (Physics.Raycast(ray, out hit)) 
                    {
                        if (hit.collider == transform.collider) 
                        {
                            // Here transform.collider is the collider of that gameobject on which you attach this script
                            // Your Rest of the Logic Here
                        }
                    }
                }
            }

            // This Will work on Android Device ////////////////////////////////////////////////////////////////////////
            else if(Application.platform == RuntimePlatform.Android)
            {   
                if (Input.touchCount > 0)
                {
                    for (int i = 0; i < Input.touchCount; i++)
                    {
                        ray = hudCamera.ScreenPointToRay(Input.GetTouch(i).position);
                        if (Input.GetTouch(i).phase == TouchPhase.Began)
                        {
                            if (Physics.Raycast(ray, out hit))
                            {
                                if (hit.collider == transform.collider)
                                {
                                    // Here transform.collider is the collider of that gameobject on which you attach this script
                                    // Your Rest of the Logic Here
                                }
                            }
                        }

                        if (Input.GetTouch(i).phase == TouchPhase.Moved)
                        {
                            // Logic for finger move on screen
                        }

                        if (Input.GetTouch(i).phase == TouchPhase.Ended)
                        {
                            if (Input.GetTouch(i).fingerId == fingerId)
                            {
                                fingerId = -1;
                                // Logic when touch ends 
                            }
                        }
                    }
                }
            }
