Can a prefab be written in code?

I don't mean instantiated, but can you actually create a (say, C#, although I'm not fussy :-) class that represents a Prefab? And if so, what would that class look like?

All the explanations that I've seen involve creating prefabs using the IDE.

Thanks for any insights!

Well, you can certainly do this in code. Consider this psuedo code for example:

public GameObject CreateMilkBottle()
{
    var prefab = new GameObject("Milkbottle");
    var milk = prefab.AddComponent<MilkContainer>();
    milk.Capacity = 300;
    var meshFilter = prefab.AddComponet<MeshFilter>();
    meshFilter.mesh = loadmesh();
    prefab.AddComponent<MeshRenderer>();
    prefab.AddComponent<BoxCollider>();
    // etc
    return prefab;
}

If you really want it on disk, try this: http://unity3d.com/support/documentation/ScriptReference/AssetDatabase.CreateAsset.html

have a look at PrefabUtility.CreateEmptyPrefab
that creates things like prefabs programatically. :slight_smile:
