| version | 导入管线用以检测导入器脚本新版本的数字。更改此数字会触发与所列扩展名匹配的所有资源的重新导入。 |
| exts | List of file name extensions (not including the leading period character) that the scripted importer handles. |
| ext | Single file name extension (not including the leading period character) that the scripted importer handles. |
| importQueueOffset | 根据类型控制资源导入顺序。正值表示推迟源资源文件的处理，而负值则将它们放在导入过程比较靠前的部分。 |
| overrideExts | List of file name extensions (not including the leading period character) that the scripted importer can handle in addition to the default file name extension(s). |
使用 ScriptedImporter 属性可向 Unity 的资源导入管线注册派生自 ScriptedImporter 的自定义资源导入器。
Always increment a scripted importer's version number whenever the script changes. This forces Assets imported with lower version numbers to be re-imported.
If the Editor's Auto Refresh preference is enabled, editing a script outside of the editor and saving it triggers a re-import of both the script and all Assets of the corresponding type.
The following example declares an importer that handles files with extension cb and cube.
using UnityEngine; using UnityEditor.AssetImporters;
[ScriptedImporter(1, new[] {"cb", "cube"})] public class CubeImporter : ScriptedImporter { public override void OnImportAsset(AssetImportContext ctx) { // ... } }
下面的示例声明一个导入器，它处理具有 sphere 扩展名的文件。它的 importQueueOffset 参数设置为 10，强制在所有其他 importQueueOffset 小于 10 的脚本化导入器之后导入具有 sphere 扩展名的资源。
using UnityEngine; using UnityEditor.AssetImporters;
[ScriptedImporter(1, "sphere", 10)] public class SphereImporter : ScriptedImporter { public override void OnImportAsset(AssetImportContext ctx) { // ... } }
The following example declares an importer that handles files with the extension fbb and that can be used to import fbx files instead of Unity's default ModelImporter.
using UnityEngine; using UnityEditor.AssetImporters;
[ScriptedImporter(1, new[] {"fbb"}, new[] {"fbx"})] public class CustomModelImporter : ScriptedImporter { public override void OnImportAsset(AssetImportContext ctx) { // ... } }
