unity4怎么把prefab里的属性与另一个perfab关联

Question

是其中一个属性

// Picking logic: Since we don't have gizmos.drawmesh, draw a bounding cube around each thingy

// Baking stuff: Copy in all the referenced objects into the scene on play or build

[ PostProcessScene ( - 2 ) ]

public static void OnPostprocessScene ( ) {

}

if ( ! pi . prefab || ! pi . enabled )

return ;

pi . enabled = false ;

GameObject go = PrefabUtility . InstantiatePrefab ( pi . prefab ) as GameObject ;

Quaternion rot = go . transform . localRotation ;

Vector3 scale = go . transform . localScale ;

go . transform . parent = pi . transform ;

go . transform . localPosition = Vector3 . zero ;

go . transform . localScale = scale ;

go . transform . localRotation = rot ;

pi . prefab = null ;

foreach ( PrefabInstance childPi in go . GetComponentsInChildren < PrefabInstance > ( ) )

不是代码，就是软件操作。
