Thank you very much for help, but I'm so dumb at commands and I have to know what command blocks I have to exactly make and what commands give to it. So if player is clicking start it does ", courier, monospace">/scoreboard players reset counter count. And I have to do ", courier, monospace">/scoreboard objectives add count dummy one time just to create scoreboard. But what about that other two commands and for example 3 commands I want to do when player wins?
Are chain command blocks have to be conditional? Let's say I make something like when player wins it teleport for all players and tellraw who won. How command blocks should looks like and what commands should be in it?
Sorry for so much questions, I don't know anything about chain command blocks, execute, scoreboards etc. + English isn't my main language.
