打印
fmt.Println("hello world")
fmt.Printf("The variable i is now: %d\n", i)

GO int64和int32相互转换必须强转
int64 roomIdTemp
int32 roomId = int32(roomIdTemp)

go的指针也是用.调用

go的枚举不可以用直接写整形赋值

常用

打印
fmt.Println("hello world")
fmt.Printf("The variable i is now: %d\n", i)

GO int64转int32
roomId = int32(roomIdTemp)

go的指针也是用.调用

go的枚举不可以用直接写整形赋值

goint64,和int32必须手动强转

：= 声明并赋值

格式化			
accountName := core.Sprintf("机器人%d", i)


if语句
if role == nil {	//不能if(), {不能换行
	return errutil.ErrRoleNotFound
}else{				//else不能换行
}

if role := rolemanager.RoleManager.Find(player.RoleId); role != nil {
}

for循环
for i := 0; i < 1000; i++ {	//不能for()
}
for true {
	for _, session := range PlayerList {	//和lua的 for k, v 差不多， PlayerList是数组或者map
	
	}
}

var PlayerList = make(map[string]*core.Session)

数组
arr := [...]int{6, 7, 8}


类的概念


go语言没有.h的概念

package roles						//类似于lua的模块，外部调用的时候需要用到

import "soccer/message"				//类似于c++的include

type Robot struct {					//和c++的class差不多，用于声明对象的属性
	Id   int32
	Camp message.ECamp
}

func NewRobot(id int32, camp message.ECamp) *Robot {		//构造函数
	return &Robot{Id: id, Camp: camp}
}

//第一个括号c++的类的作用域::，第二个括号是参数，参数后面是返回值，如果返回多个值用括号，返回单个值不用括号
func (r *Robot) RobotInfo() *message.Group_RobotInfo {
	return &message.Group_RobotInfo{
		RobotId: r.Id,
		Camp:    r.Camp,
	}
}

//外部调用
robot := roles.NewRobot(group.robotId, camp)

go没有public 和 privite
函数首字母大小是punblic,首字母小写是privite

runtime.GOMAXPROCS(1) //设置cpu的核的数量，从而实现高并发

编译linux版本
下载babun，windows安装
到代码所在目录  go build
如果没东西就cd ..返回上一层
默认编译出来是exe
编译linux版本
#!/usr/bin/env bash
export GOARCH=amd64
export GOOS=linux
go build
