关于使用Protobuf的好处本篇文章就不做介绍了,考虑到Protobuf不支持.Net3.5及以下版本,所以如果想在Unity3D中使用,则需要用到第三方的Protobuf-net库。
首先从gitHub上下载源码 https://github.com/mgravell/protobuf-net
然后进入如下目录下
点击.csproj,进入工程 编译一下,得到如下图:
把protobuf-net.dll加入到
打开该目录下的.csproj,进入工程 编译一下 ,进入如下目录
在该目录下有一个.proto文件,我们的目的是将.proto文件转化为.cs文件
写一个批处理 创建一个xx.Bat批处理
内容:
@echo off
rem 查找文件
for /f "delims=" %%i in ('dir /b ".\*.proto"') do echo %%i
rem 转cpp for /f "delims=" %%i in ('dir /b/a "*.proto"') do protoc -I=. --cpp_out=. %%i
for /f "delims=" %%i in ('dir /b/a "*.proto"') do protogen -i:%%i -o:%%~ni.cs
pause
然后点击xx.Bat 可以批处理文件夹下的.proto文件转化为.cs,然后可以看见文件夹下有生成的.cs文件
现在我们来自己写一个
message Person {
required string name=1;
required int32 id=2;
optional string email=3;
enum PhoneType {
MOBILE=0;
HOME=1;
WORK=2;
}
message PhoneNumber {
required string number=1;
optional PhoneType type=2 [default=HOME];
}
repeated PhoneNumber phone=4;
}
requied是必须有的字段、optional是可有可无的字段、repeated是可以重复的字段(数组或列表),同时枚举字段都必须给出默认值。
然后点击xx.Bat 就生成了我们想要的

set { _email = value; }
}

public global::System.Collections.Generic.List<Person.PhoneNumber> phone
{
get { return _phone; }
}
[global::System.Serializable, global::ProtoBuf.ProtoContract(Name=@"PhoneNumber")]
public partial class PhoneNumber : global::ProtoBuf.IExtensible
{
public PhoneNumber() {}
private string _number;
[global::ProtoBuf.ProtoMember(1, IsRequired = true, Name=@"number", DataFormat = global::ProtoBuf.DataFormat.Default)]
public string number
{
get { return _number; }
set { _number = value; }
}
private Person.PhoneType _type = Person.PhoneType.HOME;
[global::ProtoBuf.ProtoMember(2, IsRequired = false, Name=@"type", DataFormat = global::ProtoBuf.DataFormat.TwosComplement)]
[global::System.ComponentModel.DefaultValue(Person.PhoneType.HOME)]
public Person.PhoneType type
{
get { return _type; }
set { _type = value; }
}
private global::ProtoBuf.IExtension extensionObject;
global::ProtoBuf.IExtension global::ProtoBuf.IExtensible.GetExtensionObject(bool createIfMissing)
{ return global::ProtoBuf.Extensible.GetExtensionObject(ref extensionObject, createIfMissing); }
}
[global::ProtoBuf.ProtoContract(Name=@"PhoneType")]
public enum PhoneType
{
[global::ProtoBuf.ProtoEnum(Name=@"MOBILE", Value=0)]
MOBILE = 0,
[global::ProtoBuf.ProtoEnum(Name=@"HOME", Value=1)]
HOME = 1,
[global::ProtoBuf.ProtoEnum(Name=@"WORK", Value=2)]
WORK = 2
}
private global::ProtoBuf.IExtension extensionObject;
global::ProtoBuf.IExtension global::ProtoBuf.IExtensible.GetExtensionObject(bool createIfMissing)
{ return global::ProtoBuf.Extensible.GetExtensionObject(ref extensionObject, createIfMissing); }
}
}
接下来要在Unity中应用 还应该把protobuf-net的源码放入Plugins
接着在Asset目录下创建smcs.rsp
内容为:
-unsafe
然后把你生成的.cs文件放入 就OK了
