Minecraft – How to detect if 2 players have the same scoreboard

minecraft-commandsminecraft-java-edition

I am making a minigame when two players are needed to start an arena !
Trying with the c selector for count, but it seems that doesn't work
This is the command I used:

/testfor @a[score_arena_min=1,score_arena=1,c=2]

The arena scoreboard notes the players who joined an arena, the 1 value being for arena 1.

Can someone give me another solution than that?

The c parameter is to limit the maximum number of targets to obtain rather than a minimum. For example, if there were 3 possible matches while c was set to 2, only the 2 closest would be selected. If there were only 1 target possible, then only that target is obtained.

Since you know the exact score and number of players you want to look for, you can check the command block's SuccessCount integer tag value without changing the command you're using. If it's 0, then no players were found. If it's 1, then only 1 player was found. If it's 2, then 2 (or more) players were found with that score.

The command you're currently running which will set the command block's success count appropriately.
```
/testfor @a[score_arena_min=1,score_arena=1,c=2]
```
Check the command block's SuccessCount value to ensure it is 2. Modify the XYZ coordinates to target the repeating block.
```
/testforblock X Y Z minecraft:repeating_command_block -1 {SuccessCount:2}
```
Conditional. Action to perform as a result of there being at least 2 players that matched.
```
/say Starting with players: @a[score_arena_min=1,score_arena=1,c=2]
```

Create scoreboard objective:

/scoreboard objectives add inArena dummy

Run on clock to give people in the arena an inArena score of 1:

/scoreboard players set @a inArena 0
/scoreboard players set @a[x=<X>, y=<y>, z=<z>, dx=<X length>, dy=<Y length>, dz=<Z length>] inArena 1

To display the title to people with inArena of 1:

/title @a[score_inArena_min = 1] <Title>

Minecraft – How to target entities relative to the executor in scoreboard operations

While c=1 does create a sender bias, it also has the potential to create a "player" bias, which will attempt to target players first before targeting non-player entities. A player bias is dependent on the command/feature. The only cases where a player bias occurs is with /scoreboard commands (not counting /scoreboard teams join ... or /scoreboard players tag ...) and stored CommandStats.

The solution is to prevent targeting players, such as either with the type=!Player parameter:

/execute @e[name=setter] ~ ~ ~ scoreboard players operation @e[name=getter] test = @e[type=!Player,c=1] test

Or targeting the specific type of entity with @e[type=ArmorStand]:

/execute @e[name=setter] ~ ~ ~ scoreboard players operation @e[name=getter] test = @e[type=ArmorStand,c=1] test
