回転 GUI シーン切り替え

var playerObj : GameObject;
var aTexture : Texture;

function OnGUI () {
	var pivotPoint : Vector2 = Vector2(35, 35);
	var angleY : float = playerObj.transform.localEulerAngles.y;
	GUIUtility.RotateAroundPivot(angleY, pivotPoint);
	GUI.DrawTexture(Rect(5, 5, 60, 60), aTexture);
}

↓のScriptをGameObject>Emptyにくっつける。→Hierarchyに存在するので表示

function OnGUI () {
if (GUI.Button (Rect (10,10,150,100), "I am a button")) {
print ("You clicked the button!");
}
}

function OnGUI () {
if (GUI.Button (Rect (10,10,100,50), "Main stage")) {
Application.LoadLevel ("mainstage");
}
if (GUI.Button (Rect (120,10,100,50), "Killball stage")) {
Application.LoadLevel ("killballstage");
}
if (GUI.Button (Rect (230,10,100,50), "Spawn stage")) {
Application.LoadLevel ("spawnstage");
}
}
//これを１つのGameObject>Emptyにくっつけると３つのボタンが表示される

■GUI　シーン切替時　消えないで！
function Awake () {
DontDestroyOnLoad (this);
}
