這一篇文章主要是想分享 Unity的場景切換，那切換到不同的場景，要怎麼樣使用上一個場景所帶來的資料。
SongSelect Scene
按下Start按鈕開始，要把資料帶到下一個遊戲頁面。
MusicData.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[CreateAssetMenu(fileName = "MusicData", menuName = "Rhythm/MusicData")]
public class MusicData : ScriptableObject
{
public string musicName;
public string author;
public AudioClip audioClip;
public Sprite coverImage;
public int bpm;
public float length;
}SongDetailUI.cs
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class SongDetailUI : MonoBehaviour
{
public Image coverImage;
public TMPro.TextMeshProUGUI titleText;
public TMPro.TextMeshProUGUI artistText;
public TMPro.TextMeshProUGUI infoText;
private MusicData current;
public void ShowMusic(MusicData music)
{
current = music;
// 將音樂資料帶入右邊的detail UI
coverImage.sprite = music.coverImage;
titleText.text = music.musicName;
artistText.text = music.author;
infoText.text = $"BPM: {music.bpm} Length: {music.length}";
}
public void Btn_Play() {
if (current == null) {
Debug.LogError("沒有選擇歌曲，無法開始遊戲");
return;
}
// 將音樂存到GameData
GameData.selectedMusic = current;
SceneManager.LoadScene("GameScene");
}
}Button 觸發轉場
在Start按鈕定義的事件
public void Btn_Play() {
if (current == null) {
Debug.LogError("沒有選擇歌曲，無法開始遊戲");
return;
}
// 將音樂存到GameData
GameData.selectedMusic = current;
SceneManager.LoadScene("GameScene");
}在另外一個遊戲場景，已經可以聽到點擊的對應的資料音樂。
透過 MusicData music = GameData.selectedMusic; 抓取剛剛的音樂。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GameMusicPlayer : MonoBehaviour
{
private void Start() {
MusicData music = GameData.selectedMusic;
if (music == null) {
Debug.LogError("沒有選擇歌曲，無法開始遊戲");
return;
}
// 抓到全域的AudioSource
AudioSource audio = GetComponent<AudioSource>();
audio.clip = music.audioClip;
audio.Play();
Debug.Log("開始播放：" + music.musicName);
}
}成功取得音樂
以上就是轉場還有資料怎麼使用的一個概略展示。
