根因分析
IL2CPP代码剥离或类型转换问题,其中整数数组被错误地转换为浮点数组,通常是由于不安全的代码或封送处理。
English
IL2CPP code stripping or type conversion issue where an int array is incorrectly cast to a float array, often due to unsafe code or marshaling.
官方文档
https://docs.unity3d.com/Manual/IL2CPP-ErrorCodes.html解决方案
-
避免直接数组类型转换;使用Array.ConvertAll()或LINQ Select()创建新数组:float[] floatArray = intArray.Select(i => (float)i).ToArray();
-
使用[Il2CppSetOption(Option.NullChecks, false)]标记方法以抑制IL2CPP检查,但仅在转换安全时使用(不推荐用于生产)。
无效尝试
常见但无效的做法:
-
50% 失败
Disabling code stripping entirely may fix the cast but increases build size and hides the real issue; the cast is still incorrect.
-
75% 失败
Adding explicit casts in C# code does not help because the error occurs during IL2CPP conversion of array types, not at runtime.
