using System.Collections.Generic; using UnityEngine; [System.Serializable] public class IngredientData { public string name; public float amount; public float maxAmount; public Sprite icon; } public class IngredientManager : MonoBehaviour { [SerializeField] private ListIngredientData ingredients; public static IngredientManager Instance { get; private set; } private void Awake() { if (Instance null) { Instance this; DontDestroyOnLoad(gameObject); } else { Destroy(gameObject); } } public bool AddIngredient(string ingredientName, float amount) { IngredientData ingredient ingredients.Find(i i.name ingredientName); if (ingredient ! null) { ingredient.amount Mathf.Clamp(ingredient.amount amount, 0, ingredient.maxAmount); return true; } return false; } public bool UseIngredient(string ingredientName, float amount) { IngredientData ingredient ingredients.Find(i i.name ingredientName); if (ingredient ! null ingredient.amount amount) { ingredient.amount - amount; return true; } return false; } }3.2 物理交互系统汤圆制作的核心是物理交互我们需要实现面团的可变形效果// Scripts/Gameplay/DoughPhysics.cs using UnityEngine; [RequireComponent(typeof(MeshFilter), typeof(MeshRenderer))] public class DoughPhysics : MonoBehaviour { private Mesh doughMesh; private Vector3[] originalVertices; private Vector3[] deformedVertices; [SerializeField] private float deformationStrength 0.1f; [SerializeField] private float elasticity 0.8f; private void Start() { doughMesh GetComponentMeshFilter().mesh; originalVertices doughMesh.vertices; deformedVertices doughMesh.vertices; } private void Update() { // 逐渐恢复原始形状 for (int i 0; i deformedVertices.Length; i) { deformedVertices[i] Vector3.Lerp(deformedVertices[i], originalVertices[i], elasticity * Time.deltaTime); } doughMesh.vertices deformedVertices; doughMesh.RecalculateNormals(); } public void DeformAtPoint(Vector3 point, float force) { for (int i 0; i deformedVertices.Length; i) { Vector3 worldVertex transform.TransformPoint(originalVertices[i]); float distance Vector3.Distance(worldVertex, point); if (distance 0.5f) { Vector3 deformation (worldVertex - point).normalized * force * deformationStrength * (1 - distance / 0.5f); deformedVertices[i] transform.InverseTransformVector(deformation); } } } }3.3 触控输入处理移动端触控操作的实现// Scripts/Gameplay/TouchInputHandler.cs using UnityEngine; public class TouchInputHandler : MonoBehaviour { [SerializeField] private LayerMask doughLayer; [SerializeField] private float touchForce 1.0f; private Camera mainCamera; private DoughPhysics currentDough; private void Start() { mainCamera Camera.main; } private void Update() { HandleTouchInput(); } private void HandleTouchInput() { if (Input.touchCount 0) { Touch touch Input.GetTouch(0); Vector2 touchPosition touch.position; if (touch.phase TouchPhase.Began) { Ray ray mainCamera.ScreenPointToRay(touchPosition); RaycastHit hit; if (Physics.Raycast(ray, out hit, 100f, doughLayer)) { currentDough hit.collider.GetComponentDoughPhysics(); } } else if (touch.phase TouchPhase.Moved currentDough ! null) { Ray ray mainCamera.ScreenPointToRay(touchPosition); RaycastHit hit; if (Physics.Raycast(ray, out hit, 100f, doughLayer)) { currentDough.DeformAtPoint(hit.point, touchForce); } } else if (touch.phase TouchPhase.Ended) { currentDough null; } } } }4. 完整游戏流程实现4.1 游戏状态管理使用状态模式管理游戏的不同阶段// Scripts/Manager/GameStateManager.cs using UnityEngine; public enum GameState { Preparation, // 准备原料 Mixing, // 和面 Wrapping, // 包馅 Cooking, // 煮汤圆 Scoring // 评分 } public class GameStateManager : MonoBehaviour { public static GameStateManager Instance { get; private set; } public GameState CurrentState { get; private set; } public System.ActionGameState OnStateChanged; private void Awake() { Instance this; CurrentState GameState.Preparation; } public void ChangeState(GameState newState) { if (CurrentState ! newState) { CurrentState newState;

} GameStateManager.Instance.ChangeState(GameState.Mixing); } public void UpdateDoughConsistency(float consistency) { currentDoughConsistency consistency; // 实时反馈面团状态 if (Mathf.Abs(consistency - perfectDoughConsistency) 0.1f) { UIManager.Instance.ShowHint(面团状态完美); } } public void WrapTangYuan(float quality) { wrappedCount; if (Mathf.Abs(quality - 1.0f) wrappingTolerance) { perfectWrappedCount; UIManager.Instance.ShowSuccessEffect(); } if (wrappedCount 10) // 完成10个汤圆 { GameStateManager.Instance.NextState(); } } public float CalculateFinalScore() { float consistencyScore 1 - Mathf.Abs(currentDoughConsistency - perfectDoughConsistency); float wrappingScore (float)perfectWrappedCount / wrappedCount; float efficiencyScore Mathf.Clamp01(1 - (Time.time - gameStartTime) / 300f); // 5分钟内完成 return (consistencyScore * 0.4f wrappingScore * 0.4f efficiencyScore * 0.2f) * 100f; } private float gameStartTime; private void Start() { gameStartTime Time.time; } }4.3 UI界面系统实现游戏界面和用户交互// Scripts/UI/UIManager.cs using UnityEngine;

} public void UpdateScoreDisplay(float score) { scoreText.text $评分: {score:F1}; } public void UpdateTimer(float remainingTime) { int minutes Mathf.FloorToInt(remainingTime / 60); int seconds Mathf.FloorToInt(remainingTime % 60); timerText.text ${minutes:00}:{seconds:00}; } }5. 性能优化与移动端适配5.1 内存优化策略移动端游戏需要特别注意内存使用// Scripts/Utility/MemoryOptimizer.cs using UnityEngine; using System.Collections; public class MemoryOptimizer : MonoBehaviour { [SerializeField] private int targetFrameRate 60; [SerializeField] private bool enableGCCollect true; private void Start() { // 设置目标帧率 Application.targetFrameRate targetFrameRate; // 定期清理内存 if (enableGCCollect) { StartCoroutine(AutoGarbageCollection()); } } private IEnumerator AutoGarbageCollection() { while (true) { yield return new WaitForSeconds(30f); // 每30秒清理一次 System.GC.Collect(); Resources.UnloadUnusedAssets(); } } // 对象池管理 public class ObjectPoolT where T : MonoBehaviour { private QueueT pool new QueueT(); private T prefab; public ObjectPool(T prefab, int initialSize) { this.prefab prefab; for (int i 0; i initialSize; i) { T obj GameObject.Instantiate(prefab); obj.gameObject.SetActive(false); pool.Enqueue(obj); } } public T GetObject() { if (pool.Count 0) { T obj pool.Dequeue(); obj.gameObject.SetActive(true); return obj; } else { return GameObject.Instantiate(prefab); } } public void ReturnObject(T obj) { obj.gameObject.SetActive(false); pool.Enqueue(obj); } } }5.2 触控优化针对移动端触控操作的优化// Scripts/Gameplay/TouchOptimizer.cs using UnityEngine; public class TouchOptimizer : MonoBehaviour { [SerializeField] private float touchSensitivity 1.0f; [SerializeField] private float touchDeadZone 0.1f; private Vector2[] previousTouchPositions; private void Start() { previousTouchPositions new Vector2[5]; // 支持最多5点触控 } public Vector2 GetSmoothedTouchDelta(int touchIndex) { if (touchIndex 0 || touchIndex Input.touchCount) return Vector2.zero; Touch touch Input.GetTouch(touchIndex); Vector2 delta touch.deltaPosition * touchSensitivity; // 死区过滤 if (delta.magnitude touchDeadZone) return Vector2.zero; return delta; } public bool IsValidTouch(Vector2 position) { // 检查触摸点是否在有效区域内 Rect safeArea Screen.safeArea;
