Let the World See the Carnage – Saving and Loading High Scores - Unity 4 Game Development - page 543

public string name;
public int score;
public int CompareTo (UserData compare )
{
// Null value means that this object is greater
if (compare == null) return 1;
else {
return this.score.CompareTo(compare.score);
}
}
}
In this step in C# script, we added [System.Serializable] to enable the
ability to serialize the UserData object. This process will translate the object
data structure to a series of bits, which can easily be stored in a file or memory
buffer. On the other hand, we don't need to include any script for Unity JavaScript
because all Unity JavaScript classes are automatically serialized. This script is
used to contain the information for each user. This will be used with Bin-
aryFormatter and MemoryStream to save multiple users' data to the local
machine using PlayerPrefs in the Saving and loading the local high score
section.
Tip
In C#, sometimes, we add [System.Serializable] in our code to embed a
class with subproperties in the inspector. This is similar to how Vector3 looks
in the inspector. However, we don't need to add anything for Unity JavaScript be-
cause the Serializable attribute is implicit and not necessary.
More details can be found at http://docs.unity3d.com/Documentation/ScriptRefer-
ence/Serializable.html .
