Unity-为什么我的gameObject会闪烁

Question

所以基本上我有一个平台游戏，我遇到了一些问题 -

（有点癫痫警告！）

正如您所看到的，屏幕闪烁了很多，而且无法播放。相机移动脚本在这里 -

        //camera rotation
    float mouseX = Input.GetAxis("Mouse Y");
    float mouseY = Input.GetAxis ("Mouse X");

    float rotAmountX = -mouseX * Mousesens;
    float rotAmountY = mouseY * Mousesens;

    Vector3 targetRot = transform.rotation.eulerAngles;
    Vector3 targetRotI = CameraF.transform.rotation.eulerAngles;

    targetRotI.x += rotAmountX;
    targetRot.y += rotAmountY;

    transform.rotation = Quaternion.Euler (targetRotI);
    CameraF.transform.rotation = Quaternion.Euler (targetRot);

和CameraF只是相机。如果需要，整个脚本都在这里 -
