Buka file manifest, lalu tambahin code ini di setiap activity:
android:screenOrientation="sensorLandscape"
GameObject go = GameObject.Find("somegameobjectname");
ScriptB other = (ScriptB) go.GetComponent(typeof(ScriptB));
other.DoSomething();
var myVar = GameObject.Find("Game Object Name");
myVar.SendMessage("Function Name");
