如何在unity3d上加载上一个场景
我在构建设置中总共有五个级别。我需要装货。当玩家死亡时。“场景”切换以重新启动场景。我有重启场景代码。因此，它只会重新启动当前场景。我不想让它那样做。我需要重新加载上一个。我需要对其他级别执行相同的操作。这是我的密码：如何在unity3d上加载上一个场景,unity3d,load,unityscript,scene,Unity3d,Load,Unityscript,Scene,我在构建设置中总共有五个级别。我需要装货。当玩家死亡时。“场景”切换以重新启动场景。我有重启场景代码。因此，它只会重新启动当前场景。我不想让它那样做。我需要重新加载上一个。我需要对其他级别执行相同的操作。这是我的密码： { #pragma strict import UnityEngine.SceneManagement; @script AddComponentMenu ("EGUI/UI_Elements/Button") // public class EGUI_Button
