Detect if member has a role-CodePudding

I am building a Discord bot, more specific, a rolecolor command. I made a version of this command, that worked. Only problem was that it was extremly inefficient, it took like 5 minutes for it to respond. This was because there where a lot of 'if' statements and other things the bot had to check before executing anything. The file had 129K lines, and my whole editting program was lagging. I now have a new plan, that is probably much more efficient:

The bot checks if a member has any roles that start with "SRC -". SRC means server role color, just a name every role has that is dedicated to being cosmetic. All my colorrole names start with "SRC - name" If it detects any, delete them. Await this process, and after that, add the new color. I have like 205 roles for colors. I CAN just do:

 message.guild.members.cache
            .get(user.id)
            .roles.remove(roleone);
 message.guild.members.cache
            .get(user.id)
            .roles.remove(roletwo);

This works, but then again, inefficient. Discord isn't that fast with deleting and adding roles. When I ran a test, it didn't give me any errors. Despite this, I thought something was going wrong because my roles wheren't changing. When I was running a debug, and checked again, the roles where finally updated. It just takes a while before updating. I would like to have this more efficient. Here are some code samples:

Role adding, after the role removal:

if (args[0] === "1") {
            message.guild.members.cache
            .get(user.id)
            .roles.add(roleone);
            message.channel.send(errmsg);
            console.log(logmsg);
else if (args[0] === "2") //etc

So my question is, does someone know how to detect if the member has any roles that start with name, so that only those roles can be deleted?

CodePudding user response：

.remove() takes either a RoleResolvable, Array of RoleResolvables, or a Collection of RoleResolvables. You can filter the roles and pass it in

const member = message.guild.members.resolve(user.id)
const roles = member.roles.cache.filter(r => r.name.startsWith(`SRC -`))
await member.roles.remove(roles) // remove all roles from the member that start with "SRC -"
