游戏主界面
创建场景StartScene.tscn作为游戏的开始界面，分别显示游戏名称，游戏难度，开始游戏，设置，退出游戏，点击开始游戏进入游戏主场景，进行游戏。
游戏脚本参考如下：
using Godot; using Othello; using System; public partial class StartScene : Node2D { private OptionButton difficultySelector; private Button startButton; private Button existButton; public override void _Ready() { difficultySelector = GetNode<OptionButton>("CanvasLayer/Control/CenterContainer/VBoxContainer/OptionButton"); startButton = GetNode<Button>("CanvasLayer/Control/CenterContainer/VBoxContainer/Start"); existButton = GetNode<Button>("CanvasLayer/Control/CenterContainer/VBoxContainer/Exist"); startButton.Pressed += OnStartPressed; existButton.Pressed += OnExistPressed; } private void OnExistPressed() { GetTree().Quit(); } private void OnStartPressed() { // 获取选择的难度 int selected = difficultySelector.Selected; int depth = selected switch { 0 => 1, // 简单 1 => 3, // 普通 2 => 5, // 困难 _ => 2, }; // 存入全局变量（推荐用 Autoload） GameSettings.AIDepth = depth; // 切换到主场景 GetTree().ChangeSceneToFile("res://Main.tscn"); } }
创建游戏玩家信息
创建玩家信息场景PlayerInfo.tscn，使用SubViewPort作为根节点，以便能够嵌套入游戏主场景中。该场景分别显示对手信息，玩家信息，倒计时，当前回合，参考场景设置如下：
在主场景中创建PlayerInfoPanel（MeshInstance3D）用来承载游戏玩家信息显示，创建SubViewport一个实例化场景PlayerInfo。
PlayerInfoPanel→Mesh：PlaneMesh；
Mesh→Material：StandardMaterial3D；
StandardMaterial3D→Resource→Local to Scene 启用；
StandardMaterial3D→Albedo→Texture：ViewportTexture；
ViewportTexture→Viewport Path：PlayerInfo。
在Main.cs中实现游戏信息显示的逻辑，参考代码如下：
private Label opponentNameLabel; private Label opponentCountLabel; private Label playerNameLabel; private Label playerCountLabel; private Label countdownLabel; private Label currentPlayerLabel; private int countdownSeconds = 30; private Timer countdownTimer; /// <summary> /// 初始化玩家信息 /// </summary> private void InitPlayerInfo() { // 获取 UI 面板节点 var infoPanel = GetNode<MeshInstance3D>("PlayerInfoPanel"); var playerInfo = GetNode<SubViewport>("PlayerInfo"); opponentNameLabel = playerInfo.GetNode<Label>("Control/VBoxContainer/PanelOpponent/VBoxContainerOpponent/OpponentNameLabel"); opponentCountLabel = playerInfo.GetNode<Label>("Control/VBoxContainer/PanelOpponent/VBoxContainerOpponent/OpponentCountLabel"); playerNameLabel = playerInfo.GetNode<Label>("Control/VBoxContainer/PanelPlayer/VBoxContainerPlayer/PlayerNameLabel"); playerCountLabel = playerInfo.GetNode<Label>("Control/VBoxContainer/PanelPlayer/VBoxContainerPlayer/PlayerCountLabel"); countdownLabel = playerInfo.GetNode<Label>("Control/VBoxContainer/PanelDesc/VBoxContainerDesc/HBoxContainer/CountdownLabel"); currentPlayerLabel = playerInfo.GetNode<Label>("Control/VBoxContainer/PanelDesc/VBoxContainerDesc/CurrentPlayerLabel"); countdownTimer = new Timer(); AddChild(countdownTimer); countdownTimer.WaitTime = 1.0f; countdownTimer.OneShot = false; countdownTimer.Timeout += OnCountdownTimeout; countdownTimer.Start(); UpdatePlayerInfo(); UpdateCountdownLabel(); } private void UpdatePlayerInfo() { opponentNameLabel.Text = "对手玩家: AI"; opponentCountLabel.Text = "黑棋数: 12"; playerNameLabel.Text = "我方玩家: 玩家"; playerCountLabel.Text = "白棋数: 10"; currentPlayerLabel.Text = currentPlayer == Piece.Black ? "黑方回合" : "白方回合"; } private void UpdateCountdownLabel() { countdownLabel.Text = $"倒计时: {countdownSeconds}s"; } private void OnCountdownTimeout() { countdownSeconds--; if (countdownSeconds <= 0) { //countdownTimer.Stop(); countdownLabel.Text = "时间到！"; // 触发超时逻辑，比如换对方走 currentPlayer = currentPlayer == Piece.Black ? Piece.White : Piece.Black; countdownSeconds = 30; UpdatePlayerInfo(); } else { UpdateCountdownLabel(); } }
