How do I use command blocks to teleport multiple random players to specific spots?

Question

I've never dabbled in command blocks before, but I'm slowly learning. I am making a murder mystery mini game. I have a ton of problems but the one I am stuck on now is I want to teleport all the remaining alive players to a table, and around the table all facing the center. I don't want to teleport anyone who has died, and I have barely learned how to use @a for all to a singular spot.

Answer 1

I'm going to assume you are using Java Edition and are playing in version 1.13 or later. I am also going to assume the "dead" players are spectators.

tag @a[gamemode=!spectator] add unteleported                  //Give the "unteleported" tag to all players not in spectator mode

Run these 2 commands before each table meeting.

tag @a[tag=unteleported,limit=1,sort=random] add teleporting  //Give the "teleporting" tag to one random unteleported player
tp @a[tag=teleporting,limit=1] <seat1> facing 12 65 12        //Teleport the player with the "teleporting" tag to the 1st 'seat' around the table (10 64 10), facing the center of the table
tag @a[tag=teleporting,limit=1] remove unteleported           //Remove the "unteleported" tag from all players with tag "teleporting"
tag @a[tag=teleporting,limit=1] remove teleporting            //Remove the "teleporting" tag from all players with tag "teleporting"

Repeat this second section for all <seat> coordinates.

Answer 2

I built a meeting table like so:

Next I built this structure high in the sky, directly above the meeting table. I made sure no blocks were above it:

Then, I took the x and z coordinates of the center of the meeting table and put it into the /spreadplayers command to get: /spreadplayers -24.50 -19.50 1 2 false @a[gamemode=!spectator]

Then: /execute as @a[gamemode=!spectator] at @s run tp @s ~ ~-24 ~ facing -24.50 57.5 -19.50

Done!

How does it work?

/spreadplayers will teleport the selected targets randomly around an area. It will avoid water/lava, among other things. That is why the stone structure in the water is actually an outline of the meeting table. Each block represents a spot where the players could teleport to.

The spreadplayers command actually spreads the players onto this structure, and then I just teleport the players downwards and facing the center of the table.

The syntax of /spreadplayers is:

spreadplayers <center> <spreadDistance> <maxRange> <respectTeams> <targets>

You can begin to see why my /spreadplayers command looks the way it does:

center = -24.50 -19.50             //The center of the meeting table (and the stone structure)
spreadDistance = 1 block           //I want the players to be spread at least 1 block apart
maxRange = 2 blocks                //I want the spreadplayers command to try to spread players within 2 blocks.
respectTeams = false               //Since I'm not using teams, I don't care about keeping them together
targets = @a[gamemode=!spectator]  //I don't want to teleport dead players

to do this. you cant do it with ONE command block, you need to have as many random players as you want. or you do /spreadplayers or you choose about 50 different locations and put it in 50 command blocks. then you do [tp @r X Y Z].
