我刚开始使用这种"访问者模式"风格，并通过VisitHairDef方法遇到了代码循环5次的问题。每次这个方法循环时，HairDef对象被重新创建，随后在将其写入ColonistManager.Population[i].HairDef对象之前，每个循环只存储一条信息。因此，最终结果是只有一个变量被存储在ColonistManager.Population[i].HairDef中。我不知道为什么这个特定的部分是循环的，我希望有更多经验的人可以为我提供一些启示。如果需要更多的信息，我已经上传了我的全部源代码到dropbox: https://www.dropbox.com/s/eeq8hwwaoa2ld0b/ColonistCreationMod%20Source.zip
使Colonist.HairDef在Colonist的构造函数中初始化。然后在VisitHairDef中，直接在ColonistManager.Population[i].HairDef上设置属性。
public class Colonist
{
public HairDef HairDef { get; set; }
public Colonist()
{
HairDef = new HairDef();
}
}
private static void VisitHairDef(XmlTextReader reader, int i)
{
//ColHairDef hairDef = new ColHairDef();
while (reader.MoveToNextAttribute())
{
switch (reader.Name)
{
case "DefName":
ColonistManager.Population[i].HairDef.DefName = reader.Value;
break;
case "GraphicPath":
ColonistManager.Population[i].HairDef.GraphicPath = reader.Value;
break;
case "HairGender":
string hair = reader.Value;
int hairGender = 0;
if (hair == "Any")
{
hairGender = 2;
}
else if (hair == "Female")
{
hairGender = 4;
}
else if (hair == "FemaleUsually")
{
hairGender = 3;
}
else if (hair == "MaleUsually")
{
hairGender = 1;
}
ColonistManager.Population[i].HairDef.HairGender = (HairGender)hairGender;
break;
case "Label":
ColonistManager.Population[i].HairDef.Label = reader.Value;
break;
case "Tags":
ColonistManager.Population[i].HairDef.HairTags = GetTags(reader.Value);
//ColonistManager.Population[i].HairDef = hairDef;
break;
}
}
}
我发现这是xml文件本身的问题…VisitOnSkin方法可以完美地与方法中的Clothing clothing = new Clothing();一起工作，因为xml是这样的:
<OnSkin Layer="OnSkin" Label="Button-down shirt" GraphicPath="Things/Pawn/Humanoid/Apparel/ShirtButton/ShirtButton" Color="1,1,1,1" />
HairDef的xml，然而，不是很多属性嵌套在一个节点…一旦我在一个"HairDef"节点下设置了所有属性，如下所示:
<HairDef DefName="Mop" GraphicPath="Things/Pawn/Humanoid/Hairs/Mop" HairGender="MaleUsually" Label="Mop" Tags="Urban,Rural" />
