    Unity 如何获取Texture 的内存大小

    在Unity中,要获取Texture的内存文件大小,可以使用UnityEditor.TextureUtil类中的一些函数。这些函数提供了获取存储内存大小和运行时内存大小的方法。由于UnityEditor.TextureUtil是一个内部类,我们需要使用反射来访问它。

    步骤

    • 导入UnityEditor命名空间和System.Reflection命名空间:
    using UnityEditor;
    using System.Reflection;
    • 创建一个函数来获取Texture的内存文件大小:
    public static long GetTextureFileSize(Texture2D texture)
    {
        long fileSize = 0;
        // 使用反射获取UnityEditor.TextureUtil类的Type
        Type textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");
        // 使用反射获取UnityEditor.TextureUtil类的GetStorageMemorySizeLong方法编程客栈
        MethodInfo getStorageMemorySizeLongMethod = textureUtilType.GetMethod("GetStorageMemorySizeLong", BindingFlags.Static | BindingFlags.Public);
        // 调用GetStorageMemorySizeLong方法获取存储内存大小
        fileSize = (ljavascriptong)getStorageMemorySizeLongMethod.Invoke(null, new object[] { texture });
        return fileSize;
    }
    • 创建一个函数来获取Texture的运行时内存大小:
    public static long GetTextureRuntimeMemorySize(Texture2D texture)
    {
        long memorySize = 0;
        // 使用反射获取UnityEditor.TextureUtil类的Type
        Type textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");
        // 使用反射获取UnityEditor.TextureUtil类的GetRuntimeMemorySizeLong方法
        MethodInfo getRuntimeMemorySizeLongMethod = textureUtilType.GetMethod("GetRuntimeMemorySizeLong", BindingFlags.Static | BindingFlags.Public);
        // 调用GetRuntimeMemorySizeLong方法获取运行时内存大小
        memorySize = (long)getRuntimeMemorySizeLongMethod.Invoke(null, new object[] { texture });
        return memorySize;
    }

    示例代码

    示例 1:获取Texture的存储内存大小

    using UnityEngine;
    using UnityEditor;
    using System.Reflection;
    public class TextureSizeExample : MonoBehaviour
    {
        [SerializeField]
        private Texture2D texture;
        private void Start()
        {
            long fileSize = GetTextureFileSize(texture);
            Debug.Log("Texture File Size: " + fileSize + " bytes");
        }
        private static long GetTextureFileSize(Texture2D texture)
        {
            long fileSize = 0;
            Type textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");
            MethodInfo getStorageMemorySizeLongMethod = textureUtilType.GetMethod("GetStorageMemorySizeLong", BindingFlags.Static | BindingFlags.Public);
            fileSize = (long)getStorageMemorySizeLongMethod.Invoke(null, new object[] { texture });
            return fileSize;
        }
    }

    示例 2:获取Texture的运行时内存大小

    using UnityEngine;
    using UnityEditor;
    using System.Reflection;
    public class TextureSizeExample : MonoBehaviour
    {
        [SerializeField]
        private Texture2D texture;
        private void Start()
        {
            long memorySize = GetTextureRuntimeMemorySize(texture);
            Debug.Log("Texture Runtime Memory Size: " + memorySize + " bytes");
        }
        private static long GetTextureRuntimeMemorySize(Texture2D texture)
        {
            long memorySize = 0;
            Type textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");
            MethmsRxkKiSSvodInfo getRuntimeMemorySizeLongMethod = textureUtilType.GetMethod("GetRuntimeMemorySizeLong", BindingFlags.Static | BindingFlags.Public);
            memorySize = (long)getRuntimeMemorySizeLongMethod.Invoke(null, new object[] { texture });
            return memorySize;
        }
    }

    示例 3:同时获取Texture的存储内存大小和运行时内存大小

    using UnityEngine;
    using UnityEditor;
    using System.Reflection;
    public class TextureSizeExample : MonoBehaviour
    {
        [SerializeField]
        private Texture2D texture;
        private void Start()
        {
            long fileSize = GetTextureFileSize(texture);
            long memorySize = GetTextureRuntimeMemorySize(texture);
            Debug.Log("Texture File Size: " + fileSize + " bytes");
            Debug.Log("Texture Runtime Memory Size: " + memorySize + " bytes");
        }
        private static long GetTextureFileSize(Texture2D texture)
        {
            long fileSize = 0;
            Type textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");
            MethodInfo getStorageMemor编程客栈ySizeLongMethod = textureUtilType.GetMethod("GetStorageMemorySizeLong", BindingFlags.Static | BindingFlags.Public);
            fileSize = (long)getStorageMemorySizeLongMethod.Invoke(null, new object[] { texture });
            return fileSize;
        }
        private static long GetTextureRuntimeMemorySize(Texture2D texture)
        {
            long memorySize = 0;
            Type textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");
            MethodInfo getRuntimeMemorySizeLongMethod = textureUtilType.GetMethod("GetRuntimeMemorySizeLong", BindingFlags.Static | BindingFlags.Public);
            memorySize = (long)getRuntimeMphpemorySizeLongMethod.Invoke(null, new object[] { texture });
            return memorySize;
        }
    }

    注意事项

    • 确保在使用反射访问UnityEditor.TextureUtil类之前,已经导入了UnityEditor命名空间和System.Reflection命名空间。
    • 使用反射时,需要使用BindingFlags.Static | BindingFlags.Public来获取静态公共方法。
    • 在示例代码中,我们使用了Texture2D类型的变量来表示Texture,你可以根据实际情况修改代码以适应不同的Texture类型。
