小编给大家分享一下使用unity获取Text组件里text内容长度的案例,希望大家阅读完这篇文章之后都有所收获,下面让我们一起去探讨吧!
代码如下:
/// <summary>
/// 计算字符串在指定text控件中的长度
/// </summary>
/// <param name="message"></param>
/// <returns></returns>
int CalculateLengthOfText(string message,Text tex)
{
int totalLength = 0;
Font myFont = tex.font; //chatText is my Text component
myFont.RequestCharactersInTexture(message, tex.fontSize, tex.fontStyle);
CharacterInfo characterInfo = new CharacterInfo();
char[] arr = message.ToCharArray();
foreach (char c in arr)
{
myFont.GetCharacterInfo(c, out characterInfo, tex.fontSize);
totalLength += characterInfo.advance;
}
return totalLength;
}
补充:用Unity的TextAsset读取TXT文档内容,将物品信息存入字典中
Text Asset 文本资源
Text Assets are a format for imported text files. When you drop a text file into your Project Folder, it will be converted to a Text Asset. The supported text formats are:
文本资源是导入的文本文件的一个格式。当你拖入一个文本文件到你的项目时,他会被转换为文本资源。支持的文本格式有:
.txt .html .htm .xml .bytes
Properties 属性
Text
The full text of the asset as a single string.
之后需要新建一个文本txt来存放物品的属性,这里以药品为例
每一行文本对应一种物品,用逗号分隔,每个值对应属性表里的每一列属性。
之后新建c#脚本解析文本内容
private TextAsset objectsInfoListText; // 新建TextAsset变量
private Dictionary<int, ObjectInfo> objectInfoDict = new Dictionary<int,ObjectInfo>();
void Awake()
{
objectsInfoListText = Resources.Load("ObjectsInfoList") as TextAsset; // 从Resouces的path中读取到文件
ReadInfo();
}
void ReadInfo()
{
string text = objectsInfoListText.text; // 将文本内容作为字符串读取
string[] objInfoArray = text.Split('\n'); // 以\n为分割符将文本分割为一个数组
foreach (string str in objInfoArray) // 遍历每一行并将每一个药品的值放入类对象中,并存入字典
{
ObjectInfo info = new ObjectInfo();
string[] propertyArray = str.Split(',');
int id = int.Parse(propertyArray[0]);
string name = propertyArray[1];
string icon_name = propertyArray[2];
string str_type = propertyArray[3];
ObjectType type = ObjectType.Drug;
switch (str_type)
{
case "Equip":
type = ObjectType.Equip;
break;
case "Mat":
type = ObjectType.Mat;
break;
case "Drug":
type = ObjectType.Drug;
break;
}
info.id = id; info.name = name;
info.icon_name = icon_name; info.type = type;
if (type == ObjectType.Drug)
{
int hp = int.Parse(propertyArray[4]);
int mp = int.Parse(propertyArray[5]);
int price_sell = int.Parse(propertyArray[6]);
int price_buy = int.Parse(propertyArray[7]);
info.hp = hp; info.mp = mp; info.price_sell = price_sell; info.price_buy = price_buy;
}
// 将物品信息存储到字典中
objectInfoDict.Add(id, info);
}
}
public enum ObjectType
{
Drug,
Equip,
Mat,
};
public class ObjectInfo
{
public int id;
public string name;
public string icon_name;
public ObjectType type;
public int hp;
public int mp;
public int price_sell;
public int price_buy;
}
