根因分析

ScriptableObject 资源使用较新版本的类定义（例如添加了字段）序列化，但当前代码期望旧版本，导致反序列化不匹配。

English

A ScriptableObject asset was serialized with a newer version of its class definition (e.g., added fields), but the current code expects an older version, causing deserialization mismatches.

解决方案

  1. Implement custom serialization with versioning: Add a version field to the ScriptableObject and use OnBeforeSerialize/OnAfterDeserialize to handle migration. Example:
public int version = 1;
public void OnAfterDeserialize() {
    if (version < 2) {
        // migrate old data
        version = 2;
    }
}
  2. Use a custom Editor script to update all ScriptableObject assets to the latest version: Iterate through assets and call a migration method that sets default values for new fields.

无效尝试

常见但无效的做法:

  1. Delete and recreate the ScriptableObject asset from scratch 90% 失败

    This loses all existing data and may not be feasible if data is critical; also does not fix the root mismatch.

  2. Revert the script to the old version without the new fields 75% 失败

    This prevents using new features and may break other parts of the code that depend on the new fields.
