c# - 无法在 C# 中使用命名空间

Question

我正在尝试在 Unity 编辑器中开发游戏。
我无法将命名空间从一个脚本使用到另一个脚本。
请在下面找到脚本。

using System;
using UnityEngine;
using UnityStandardAssets.CrossPlatformInput;
namespace UnityStandardAssets.CrossPlatformInput
{
    public static class CrossPlatformInputManager
    {
        public enum ActiveInputMethod
        {
            Hardware,
            Touch
        }


        private static VirtualInput activeInput;

        private static VirtualInput s_TouchInput;
        private static VirtualInput s_HardwareInput;
    }
}

AxisTouchButton.cs

using System;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityStandardAssets.CrossPlatformInput;

namespace UnityStandardAssets.CrossPlatformInput
{
    public class AxisTouchButton : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
    {
        // designed to work in a pair with another axis touch button
        // (typically with one having -1 and one having 1 axisValues)
        public string axisName = "Horizontal"; // The name of the axis
        public float axisValue = 1; // The axis that the value has
        public float responseSpeed = 3; // The speed at which the axis touch button responds
        public float returnToCentreSpeed = 3; // The speed at which the button will return to its centre

        AxisTouchButton m_PairedWith; // Which button this one is paired with
        CrossPlatformInputManager.VirtualAxis m_Axis; // A reference to the virtual axis as it is in the cross platform input

        void OnEnable()
        {
            if (!CrossPlatformInputManager.AxisExists(axisName))
            {
                // if the axis doesnt exist create a new one in cross platform input
                m_Axis = new CrossPlatformInputManager.VirtualAxis(axisName);
                CrossPlatformInputManager.RegisterVirtualAxis(m_Axis);
            }
            else
            {
                m_Axis = CrossPlatformInputManager.VirtualAxisReference(axisName);
            }
            FindPairedButton();
        }
    }
}

脚本 CrossPlatformInputManager有命名空间 UnityStandardAssets.CrossPlatformInput ，但我无法在 AxisTouchButton.cs 中获得该命名空间在 Unity Monodevelop 编辑器中。

附言: 这两个文件位于不同的目录中。

有人能告诉我命名空间有什么问题吗？

谢谢，

Answer 1

当您的类已经在命名空间 UnityStandardAssets.CrossPlatformInput 中时你不需要 using对于那个命名空间。只需删除 using -陈述。

using System;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityStandardAssets.CrossPlatformInput; // remove this line
namespace UnityStandardAssets.CrossPlatformInput
{
    public class AxisTouchButton : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
    {
        ...
    }
}

这适用于两个源代码文件。

顺便说一句:属于同一命名空间的类也应该位于同一目录中。
