Question

我在Nexus 6（5.1操作系统）设备上遇到崩溃。我无法弄清楚造成这种崩溃的原因以及如何处理它。将不胜感激任何帮助。

Unity3d版本：4.6.5f1 NGUI版本：2.6.4

Answer 1

你有错误地址0xc，r3 00000000，与我的情况不完全相同。

在我的情况下，当相机上没有渲染的对象，并且camera.targetTexture设置为aRenderTexture时，它会发生，Destroy（aRenderTexture）会崩溃。

修复代码1（不推荐但有效）：

Destroy(aRenderTexture, 1.0f)

修复代码2（也许更好的方法，在崩溃的相机上附加以下脚本）：

using UnityEngine;

[RequireComponent (typeof (Camera))]
public class CrashFix : MonoBehaviour {
    void Awake () {
        Camera _cam = gameObject.GetComponent<Camera>();
        GameObject _invisibleObj = GameObject.CreatePrimitive(PrimitiveType.Quad);

        _invisibleObj.name = "CrashFix";
        _invisibleObj.layer = GetFirstLayerNumberFromMask(_cam.cullingMask);
        _invisibleObj.transform.parent = gameObject.transform;
        _invisibleObj.transform.localScale = new Vector3(0.001f, 0.001f, 0.001f);
        _invisibleObj.transform.position =
            _cam.transform.position + _cam.transform.forward * (_cam.nearClipPlane+_cam.farClipPlane)/2f;

        Material _mat = new Material(Shader.Find("UI/Default"));
        _mat.color = new Color32(0,0,0,0);

        var mr = _invisibleObj.GetComponent<MeshRenderer>();
        mr.sharedMaterial = _mat;

        Destroy(_invisibleObj.GetComponent<Collider>());
    }

    private int GetFirstLayerNumberFromMask(int mask)
    {
        if (mask == 0) return 0;

        int result = 0;
        while(true){
            if ((mask & 1) == 1) return result;

            mask >>= 1;
            ++result;
        }
    }
}

Unity3d和NGUI可能导致nexus 6（5.1）崩溃
