public const string TaskHead = "ResImages/task";
public const string WiseManHead = "ResImages/wiseman";
public const string GeneralHead = "ResImages/general";
public const string ArtisanHead = "ResImages/artisan";
public const string TraderHead = "ResImages/trader";
//AutoGudeNPC
public const int NPCWiseMan = 0;
public const int NPCGeneral = 1;
public const int NPCArtisan = 2;
public const int NPCTrader = 3;
通过路径加载图片
private Dictionary<string, Sprite> spDic = new Dictionary<string, Sprite>();
public Sprite LoadSprite(string path, bool cache = false) {
Sprite sp = null;
if (!spDic.TryGetValue(path, out sp)) {
sp = Resources.Load<Sprite>(path);
if (cache) {
spDic.Add(path, sp);
}
}
return sp;
}
private void SetSprite(Image img,string path) {
Sprite sp = LoadSprite(path, true);
img.sprite = sp;
}
最后通过id使用
private void SetGudieBtnIcon(int npcID) {
string spPath = "";
Image img = btnGuide.GetComponent<Image>();
switch (npcID) {
case Constans.NPCWiseMan:
spPath = PathDefine.WiseManHead;
break;
case Constans.NPCGeneral:
spPath = PathDefine.GeneralHead;
break;
case Constans.NPCArtisan:
spPath = PathDefine.ArtisanHead;
break;
case Constans.NPCTrader:
spPath = PathDefine.TraderHead;
break;
}
SetSprite(img, spPath);
}
