水果机，夺宝动画实现

效果（动画不流畅是gif帧率低造成的）

 

 入口代码

Assets/FruitMachine/FruitMachineDemo.cs

这个脚本挂在Layer节点上

public class FruitMachineDemo : MonoBehaviour
{private LuaEnv m_LuaEnv;private RectTransform m_Layer;private List<Action> m_Actions = new List<Action>();void Awake(){m_Layer = (RectTransform)transform;}void Start(){m_LuaEnv = new LuaEnv();m_LuaEnv.AddLoader((ref string filePath) =>{filePath = filePath.Replace('.', '/');var assetFilePath = $"Assets/{filePath}.lua.txt";
#if UNITY_EDITORfilePath = Path.GetFullPath(assetFilePath);
#endifvar txtAsset = AssetDatabase.LoadAssetAtPath<TextAsset>(assetFilePath);return Encoding.UTF8.GetBytes(txtAsset.text);});m_LuaEnv.Global.Set("FruitMachineDemoInst", this); //在lua中增加一个全局变量，可以在lua中用FruitMachineDemoInst来访问c#对象m_LuaEnv.DoString("require('FruitMachine.Main')");}void OnDestroy(){m_Actions.Clear();m_Actions = null;if (null != m_LuaEnv){m_LuaEnv.Dispose();m_LuaEnv = null;}}public RectTransform GetLayerRoot(){return m_Layer;}public void AddAction(Action action){if (null != action)m_Actions.Add(action);}public void RemoveAction(Action action){if (null != action)m_Actions.Remove(action);}void Update(){if (m_Actions.Count > 0){foreach (var act in m_Actions){act();}}}}
