如果没有天空盒，需要自己配置
新增SkyboxBlendingShader.shader，控制天空盒平滑过渡交替变化
Shader "Custom/SkyboxTransition" { Properties { _TransitionFactor("Transition Factor", Range(0, 1)) = 0.0 _AtmosphereTex("Atmosphere CubeMap", Cube) = "" {} _SpaceTex("Space CubeMap", Cube) = "" {} } SubShader { Tags { "Queue"="Background" } Pass { CGPROGRAM #pragma vertex vert #pragma fragment frag #include "UnityCG.cginc" struct appdata_t { float4 vertex : POSITION; }; struct v2f { float3 pos : TEXCOORD0; float4 vertex : SV_POSITION; }; float _TransitionFactor; samplerCUBE _AtmosphereTex; samplerCUBE _SpaceTex; v2f vert(appdata_t v) { v2f o; o.pos = v.vertex.xyz; o.vertex = UnityObjectToClipPos(v.vertex); return o; } half4 frag(v2f i) : SV_Target { // Use the transition factor to blend between the two skybox cube maps half4 atmosphereColor = texCUBE(_AtmosphereTex, i.pos); half4 spaceColor = texCUBE(_SpaceTex, i.pos); half4 finalColor = lerp(atmosphereColor, spaceColor, _TransitionFactor); return finalColor; } ENDCG } } FallBack "Skybox/Cubemap" }
配置不同时间过渡材质
新增DayNightSystem，负责管理游戏的昼夜系统
public class DayNightSystem : MonoBehaviour { // 控制方向光的引用 public Light directionalLight; // 一整天的持续时间（以秒为单位） public float dayDurationInSeconds = 24.0f; // 调整一整天的持续时间（以秒为单位） // 当前的小时 public int currentHour; // 当前的分钟 public int currentMinute; // 当前时间在一天中所占比例（范围在0到1之间） float currentTimeOfDay = 0.35f; // 存储不同时间段对应的天空盒 public List<SkyboxTimeMapping> timeMappings; // 用于插值的值（范围在0到1之间） float blendedValue = 0.0f; // 是否锁定下一个白天触发 bool lockNextDayTrigger = false; // 用于显示时间的UI元素 public TextMeshProUGUI timeUI; // 在每帧更新 void Update() { // 根据游戏时间计算当前的时间 currentTimeOfDay += Time.deltaTime / dayDurationInSeconds; currentTimeOfDay = currentTimeOfDay % 1; // 确保值在0到1之间 // 计算当前的小时 currentHour = Mathf.FloorToInt(currentTimeOfDay * 24); // 计算当前的分钟数 currentMinute = Mathf.FloorToInt(currentTimeOfDay * 1440) % 60; // 一天有 24 小时 * 60 分钟 = 1440 分钟 //更新时间UI timeUI.text = $"{currentHour:D2}:{currentMinute:D2}"; // 更新方向光的旋转 directionalLight.transform.rotation = Quaternion.Euler(new Vector3((currentTimeOfDay * 360) - 90, 170, 0)); // 根据时间更新天空盒材质 UpdateSkybox(); } // 更新天空盒材质的方法 private void UpdateSkybox() { // 寻找当前小时对应的天空盒材质 Material currentSkybox = null; foreach (SkyboxTimeMapping mapping in timeMappings) { if (currentHour == mapping.hour) { currentSkybox = mapping.skyboxMaterial; if (currentSkybox.shader != null) { if (currentSkybox.shader.name == "Custom/SkyboxTransition") { blendedValue += Time.deltaTime; blendedValue = Mathf.Clamp01(blendedValue); currentSkybox.SetFloat("_TransitionFactor", blendedValue); } else { blendedValue = 0; } } break; } } if (currentHour == 0 && lockNextDayTrigger == false) { TimeManager.Instance.TriggerNextDay(); lockNextDayTrigger = true; } if (currentHour != 0) { lockNextDayTrigger = false; } // 如果找到了对应的天空盒材质，则更新RenderSettings的skybox if (currentSkybox != null) { RenderSettings.skybox = currentSkybox; } } } // 存储时间和对应天空盒材质的类 [System.Serializable] public class SkyboxTimeMapping { public string phaseName; public int hour; // 小时 public Material skyboxMaterial; // 对应的天空盒材质 }

效果
下雨
下雨粒子效果
这里只做个简单的，想要更复杂的下雨效果，可以看我之前的文章：【实现100个unity特效之7】unity 3d实现各种粒子效果
默认禁用雨
控制雨一直跟随玩家，但是旋转不跟随
//跟随玩家 public class FollowPlayer : MonoBehaviour { public Transform player; public Vector3 offset; private void LateUpdate() { if (player != null) { Vector3 targetPosition = player.position + offset; transform.position = targetPosition; } } }
配置
控制不同天气
新增WeatherSystem
public class WeatherSystem : MonoBehaviour { [Range(0f, 1f)] public float chanceToRainSpring = 0.3f; // 春季下雨概率（30%） [Range(0f, 1f)] public float chanceToRainSummer = 0.7f; // 夏季下雨概率（70%） [Range(0f, 1f)] public float chanceToRainFall = 0.4f; // 秋季下雨概率（40%） [Range(0f, 1f)] public float chanceToRainWinter = 0f; // 冬季下雨概率（0%） public GameObject rainEffect; // 下雨特效 public Material rainSkyBox; // 下雨天气的天空盒材质 public bool isSpecialWeather; // 是否是特殊天气 public AudioSource rainChannel; // 下雨音效的音频源 public AudioClip rainSound; // 下雨音效 public enum WeatherCondition { Sunny, // 晴天 Rainy, // 下雨 Snowy // 下雪（未在代码中实现） } private WeatherCondition currentWeather = WeatherCondition.Sunny; // 当前天气默认为晴天 private void Start() { // 监听一天的流逝事件，用于生成随机天气 TimeManager.Instance.OnDayPass.AddListener(GenerateRandomWeather); } private void GenerateRandomWeather() { TimeManager.Season currentSeason = TimeManager.Instance.currentSeason; float chanceToRain = 0f; // 根据当前季节设定下雨概率 switch (currentSeason) { case TimeManager.Season.Spring: chanceToRain = chanceToRainSpring; break; case TimeManager.Season.Summer: chanceToRain = chanceToRainSummer; break; case TimeManager.Season.Fall: chanceToRain = chanceToRainFall; break; case TimeManager.Season.Winter: chanceToRain = chanceToRainWinter; break; } // 生成一个随机数，用于判断是否下雨 if (Random.value < chanceToRain) { currentWeather = WeatherCondition.Rainy; // 设置为下雨天气 isSpecialWeather = true; // 标记为特殊天气 Invoke("StartRain", 1f); // 延迟1秒开始下雨效果 } else { currentWeather = WeatherCondition.Sunny; // 设置为晴天 isSpecialWeather = false; // 标记为非特殊天气 StopRain(); // 停止下雨效果 } } private void StartRain() { if (rainChannel.isPlaying == false) { rainChannel.clip = rainSound; rainChannel.loop = true; rainChannel.Play(); } RenderSettings.skybox = rainSkyBox; // 切换天空盒为下雨天气材质 rainEffect.SetActive(true); // 激活下雨特效 } private void StopRain() { if (rainChannel.isPlaying) { rainChannel.Stop(); // 停止下雨音效 } rainEffect.SetActive(false); // 关闭下雨特效 } }
修改DayNightSystem
public WeatherSystem weatherSystem; void Update() { // 。。。 if (currentHour == 0 && lockNextDayTrigger == false) { TimeManager.Instance.TriggerNextDay(); lockNextDayTrigger = true; } if (currentHour != 0) { lockNextDayTrigger = false; } // 根据时间更新天空盒材质 if(weatherSystem.isSpecialWeather == false) UpdateSkybox(); } // 更新天空盒材质的方法 private void UpdateSkybox() { // 寻找当前小时对应的天空盒材质 Material currentSkybox = null; foreach (SkyboxTimeMapping mapping in timeMappings) { if (currentHour == mapping.hour) { currentSkybox = mapping.skyboxMaterial; if (currentSkybox.shader != null) { if (currentSkybox.shader.name == "Custom/SkyboxTransition") { blendedValue += Time.deltaTime; blendedValue = Mathf.Clamp01(blendedValue); currentSkybox.SetFloat("_TransitionFactor", blendedValue); } else { blendedValue = 0; } } break; } } // 如果找到了对应的天空盒材质，则更新RenderSettings的skybox if (currentSkybox != null) { RenderSettings.skybox = currentSkybox; } }
