Unable to properly serialize object for the player of class 'UnityEngine.GameObject' because of extra field

Questions & Answers

Hi, I am having an issue with a script not being serialized properly when building for Windows Standalone. When the exe is run, the output log says:

The file ‘C:/Users/One/Desktop/ZipZapTest/Game_Data/sharedassets0.assets’ is corrupted! Remove it and launch unity again!
[Position out of bounds! 35275732 > 35275728]

In the editor log when doing a build I get a few messages like the following:

Unable to properly serialize object for the player of class ‘UnityEngine.GameObject’ because of extra field ‘leftTurrets’ of type ‘ZZTurret modreq(System.Runtime.CompilerServices.IsVolatile)’ (expecting ‘UnityEngine.GameObject’ ‘TurretBasePrefab’)

I have seen similar questions on here that say the problem is related to having a C# and a JS script named the same thing, but I have searched through the entire project and can find no such duplicates.

The script in question looks like this:

using System.Collections;

    LaserRangeX4,
    LaserSpeedX2,
    LaserSpeedX4,

I have rewritten the script in question and things work fine now.

I just came across the same issue. It turns out to be the fields marked as public volatile (your leftTurrets and rightTurrets fields). Remove either public or volatile and the serialization issue goes away.

I wasn’t able to find any other references to this being one of the many causes of the quite common “file is corrupted! Remove it and launch unity again” error.
