null) { rb.velocity Vector3.zero; rb.angularVelocity Vector3.zero; } }9. 扩展功能与进阶玩法9.1 战役模式设计实现基于三国历史事件的战役关卡// 文件路径Assets/Scripts/GameModes/CampaignMode.cs using UnityEngine; public class CampaignMode : MonoBehaviour { [System.Serializable] public class CampaignMission { public string missionName; public string description; public UnitStats.Faction playerFaction; public int initialResources; public VictoryCondition victoryCondition; } public enum VictoryCondition { EliminateAll, CaptureFlag, SurviveTime } public CampaignMission[] missions; private int currentMissionIndex 0; public void StartMission(int missionIndex) { if (missionIndex missions.Length) { CampaignMission mission missions[missionIndex]; SetupMission(mission); } } private void SetupMission(CampaignMission mission) { // 根据任务设置初始单位和资源 Debug.Log($开始任务: {mission.missionName}); Debug.Log(mission.description); } }9.2 多人对战功能为游戏添加本地多人对战支持// 文件路径Assets/Scripts/GameModes/MultiplayerMode.cs using UnityEngine; public class MultiplayerMode : MonoBehaviour { public enum ControlScheme { Player1, Player2, AI } [System.Serializable] public class PlayerSetup { public UnitStats.Faction faction; public ControlScheme control; public int startingResources; } public PlayerSetup[] players; public void SetupMultiplayerMatch() { foreach (PlayerSetup player in players) { SetupPlayer(player); } } private void SetupPlayer(PlayerSetup player) { switch (player.control) { case ControlScheme.Player1: // 设置为玩家1控制 break; case ControlScheme.Player2: // 设置为玩家2控制 break; case ControlScheme.AI: // 设置为AI控制 break; } } }通过以上完整实现我们成功构建了一个具有三国特色的全面战争模拟器原型。这个项目不仅还原了TABS的核心玩法还融入了三国题材的策略深度。开发者可以在此基础上继续扩展更多武将、兵种和战役模式打造更加丰富的游戏体验。
