前面的一节，我们发现棋盘本来应该是白色的格子，但是显示的是灰色，这里的原因是缺少光照。我们可以在主场景中添加光照的节点。
添加DirectionalLight3D平行光，Ratation(-60.0,45.0,0,0)，添加一个环境光WorldEnvironment用于补光，Environment → 添加 New Environment ，AmbientLight 可以设置自己需要的属性，这里就使用默认的。
创建一个球场景
添加一个Ball.tscn，根节点维Node3D，添加子节点MeshInstance3D，Mesh设置为SphereMesh球体形状，Material Override 新建StandardMaterial3D。
添加脚本，主要实现球（棋子）的颜色变化，跳跃等动画效果，参考代码如下：
using Godot; using System; public partial class Ball : Node3D { private StandardMaterial3D material; public override void _Ready() { material = new StandardMaterial3D(); } public void FlipTo(Color targetColor, float duration = 0.4f) { var tween = GetTree().CreateTween(); // 旋转动画 tween.TweenProperty(this, "rotation_degrees", new Vector3(180, 0, 0), duration) .SetTrans(Tween.TransitionType.Sine) .SetEase(Tween.EaseType.InOut); // 缩放动画：放大到 1.2 再回到 1 tween.TweenProperty(this, "scale", new Vector3(1.2f, 1.2f, 1.2f), duration / 2f) .SetTrans(Tween.TransitionType.Sine) .SetEase(Tween.EaseType.Out); tween.TweenProperty(this, "scale", new Vector3(1, 1, 1), duration / 2f) .SetTrans(Tween.TransitionType.Sine) .SetEase(Tween.EaseType.In); // 跳跃动画（Y轴偏移） Vector3 startPos = Position; Vector3 peakPos = Position + new Vector3(0, 0.2f, 0); tween.TweenProperty(this, "position", peakPos, duration / 2f) .SetTrans(Tween.TransitionType.Quad) .SetEase(Tween.EaseType.Out); tween.TweenProperty(this, "position", startPos, duration / 2f) .SetTrans(Tween.TransitionType.Quad) .SetEase(Tween.EaseType.In); // 颜色过渡 Color fromColor = material.AlbedoColor; tween.TweenMethod( Callable.From((Color c) => material.AlbedoColor = c), fromColor, targetColor, duration ).SetTrans(Tween.TransitionType.Sine) .SetEase(Tween.EaseType.InOut); } }
实现黑白棋的棋子变化游戏规则
点击单元格放置一个球，判断当前位置的8个方向的棋子是否需要翻转颜色，翻转完成之后，玩家切换为对手玩家。
添加单元格点击事件，参考代码如下：
//Cell.cs using Godot; using System; public partial class Cell : Area3D { public Vector2I BoardPosition{get;set;} [Signal] public delegate void CellClickedEventHandler(Vector2I boardPos); public override void _InputEvent(Camera3D camera, InputEvent @event, Vector3 position, Vector3 normal, int shapeIdx) { if (@event is InputEventMouseButton mb && mb.Pressed && mb.ButtonIndex == MouseButton.Left) { GD.Print($"[Cell] Clicked at {BoardPosition}"); EmitSignal(nameof(CellClicked), BoardPosition); } } }
点击单元格的时候放置球，获取需要翻转的棋子的位置，翻转棋子颜色，参考代码：
//Main.cs private enum Piece { None, Black, White } private Piece[,] boardState = new Piece[BoardSize, BoardSize]; private Piece currentPlayer = Piece.Black; private void OnCellClicked(Vector2I position) { if (boardState[position.X, position.Y] != Piece.None) return; var toFlip = GetFlippablePieces(position, currentPlayer); if (toFlip.Count == 0) { GD.Print("非法落子！"); return; } // 落子 boardState[position.X, position.Y] = currentPlayer; PlacePiece(position, currentPlayer); // 翻子 foreach (var flipPos in toFlip) { boardState[flipPos.X, flipPos.Y] = currentPlayer; FlipPiece(flipPos, currentPlayer); } // 切换回合 currentPlayer = currentPlayer == Piece.Black ? Piece.White : Piece.Black; } //获取需要翻转的棋子 private List<Vector2I> GetFlippablePieces(Vector2I pos, Piece player) { List<Vector2I> totalToFlip = new(); Piece opponent = (player == Piece.Black) ? Piece.White : Piece.Black; foreach (var dir in Directions) { List<Vector2I> toFlip = new(); int x = pos.X + dir.X; int y = pos.Y + dir.Y; while (x >= 0 && x < BoardSize && y >= 0 && y < BoardSize) { var p = boardState[x, y]; if (p == opponent) { toFlip.Add(new Vector2I(x, y)); } else if (p == player) { if (toFlip.Count > 0) { totalToFlip.AddRange(toFlip); } break; } else // None { break; } x += dir.X; y += dir.Y; } } return totalToFlip; } /// <summary> /// 放置棋子 /// </summary> /// <param name="pos"></param> /// <param name="piece"></param> private void PlacePiece(Vector2I pos, Piece piece) { var ball = ballScene.Instantiate<Node3D>(); ball.Position = new Vector3(pos.X, 0.2f, pos.Y); var mesh = ball.GetNode<MeshInstance3D>("MeshInstance3D"); var mat = new StandardMaterial3D(); mat.AlbedoColor = (piece == Piece.Black) ? new Color(0, 0, 0) : new Color(1, 1, 1); mesh.MaterialOverride = mat; ball.Name = $"Piece_{pos.X}_{pos.Y}"; boardNode.AddChild(ball); } /// <summary> /// 翻转棋子 /// </summary> /// <param name="pos"></param> /// <param name="toColor"></param> private void FlipPiece(Vector2I pos, Piece toColor) { string nodeName = $"Piece_{pos.X}_{pos.Y}"; if (boardNode.HasNode(nodeName)) { var piece = boardNode.GetNodeOrNull<Ball>(nodeName); var mesh = piece.GetNode<MeshInstance3D>("MeshInstance3D"); var mat = new StandardMaterial3D(); mat.AlbedoColor = (toColor == Piece.Black) ? new Color(0, 0, 0) : new Color(1, 1, 1); mesh.MaterialOverride = mat; piece.FlipTo(currentPlayer == Piece.Black ? Colors.Black : Colors.White); } }
