ただmainStageObjの子どもとして、prefab前のtransform情報をもったまま読み込みメモ。

パッとでで来ないのでメモ。

mainStageObj

GameManager.cs

 
GameObject collectionObj = (GameObject)Resources.Load("Prefabs/Hoge/GenerateDecoObj/" + Constant.GENERATE_DECO_OBJS[growthLvInt]); //as GameObject;

GameObject collectionObjInstance;
if (growthLvInt < 3)
{
    collectionObjInstance = (GameObject)GameObject.Instantiate(collectionObj, collectionObj.transform.position, collectionObj.transform.rotation);
}
else
{
    // 2以降はあて TODO
    // // -14f 〜　14f
    float randomX = (UnityEngine.Random.value * 1000f) - 500f;
    float randomY = 500f + (UnityEngine.Random.value * 300f);

    collectionObjInstance = (GameObject)GameObject.Instantiate(collectionObj, new Vector3(randomX, randomY, -6.65f), Quaternion.Euler(0.0f, 0.0f, 0.0f));

}


if(mainStageObj){

    collectionObjInstance.transform.parent = mainStageObj.gameObject.transform;

    // prefab化前の親子関係と同じ状態で、prefabの座標をそのまま使う。
    collectionObjInstance.transform.localPosition = collectionObj.transform.localPosition;
    collectionObjInstance.transform.localScale = collectionObj.transform.localScale;
}
