如何通过并行传递指针的参考？

Question

I'm writing a bot to run some commands in parallel and at the same time run the bots in parallel, but I'm having trouble starting and pausing functions.

Below I'll leave an example I set up. It was expected that one of the bots would continue to run and others would stop, but all would end up running.

Could someone explain to me why, when using the startbot() command, it does not get bool?

package main

import (
    "log"
    "time"
)

type botBase struct {
    isEnabled bool
}

func (b *botBase) startFunctionX() {
    b.isEnabled = true
}

func (b *botBase) pauseFunctionX() {
    b.isEnabled = false
}

func (b botBase) runCommandX() {
    for {
        if b.isEnabled {
            log.Print("running...")
        } else {
            log.Print("paused...")
        }
        time.Sleep(1 * time.Second)
    }
}

type bot struct {
    botBase
    //other stuffs
}

func (b bot) runAllCommands() {
    go b.runCommandX()

    //wait parallels commands
    for{
        time.Sleep(10 * time.Hour)
    }
}

type bots struct {
    List []bot
}

func (b *bots) loadListDB() {
    b1 := bot{}
    b1.isEnabled = false
    b2 := bot{}
    b2.isEnabled = false
    b.List = []bot{b1, b2}
}

var myBots bots

func main() {
    myBots.loadListDB()
    for _, b := range myBots.List {
        b.startFunctionX()
        go b.runAllCommands()
    }

    //control stop and start bots
    log.Print("expected true = ", myBots.List[0].isEnabled)
    myBots.List[0].pauseFunctionX()
    log.Print("expected false = ", myBots.List[0].isEnabled)


    //wait bots parallels
    for {
        time.Sleep(10 * time.Hour)
    }
}

Answer 1

the range statement returns the value of a bot which is then changed so you're actually checking a different bot.. work with references -

for i := range myBots.List {
    b := &myBots.List[i]
    b.startFunctionX()
    go b.runAllCommands()
}
