How to select players who are not two specific players in Minecraft? [duplicate]

In order to do an all-but target selector, you need to add an exclamation point (!) before the name of the thing excluded from the command.

For example, the command

/testfor @a[name=!IfThenElse]

would return true if there is a player other than the player with the name IfThenElse online when the command is executed. In order to modify this command, simply replace the name IfThenElse with a different username.

With the all-but you can make an effective entity clearer:

/kill @e[type=!Player]

This would kill all entities (minecarts, mobs, dropped items) except for players.

However, since you can only select one all-but name, the scoreboard must be used.

Start by using the command

/scoreboard objectives add testnot dummy

and setting testnot to 1 on players you don't want to be effected by whatever command:

/scoreboard players set IfThenElse testnot 1

Replace IfThenElse with a username. Then you can run a command with the target selector @a[score_testnot=0], which would effect everyone but the players who had their testnot score set to 1.

I'm going to be surprised if I got the command syntax right. Edit as needed.

Normal target selectors cannot select 2 specific people, the solution is to use a scoreboard to mark the players.

Setup:

/scoreboard objectives add Selector dummy

Clock:

/scoreboard players set @a[name=<Name of Target>] Selector 1 //One of these commands per person
/scoreboard players set @a[score_Selector_min!=1] Selector 0

Selector:

@a[score_Selector=0] to select non selected

So from what people have said and some of my own research here's the easiest way to do this:

1. Set up a scoreboard, called ExcludeSelection for example:

   /scoreboard objectives add ExcludeSelection dummy

2. Set the players you want to exclude to 1 in this scoreboard:

   /scoreboard players set <username> ExcludeSelection 1 (do this for every player you want to exclude)

3. Add 0 to all player's scores (basically this adds players not on the scoreboard to the scoreboard without messing up existing values):

   scoreboard players add @a 0 (in a loop, perhaps a setblock clock)

4. And then to select all players except the ones you want to exclude, just use:

   @a[score_ExcludeSelection=0]

I personally am using this to prevent anyone except the co-owners of the server (moi and my friend) from using creative mode. Just because I feel like it, here's what I think I'm going to do in addition to the first four steps.

In a setblock clock, I'll put tell @a[score_ExcludeSelection=0,m=1] You are not allowed to use creative mode. in one command block, and in another, gamemode @a[score_ExcludeSelection=0,m=1] survival.
