Guide and examples

For an entrance, an introduction or the moment a boss appears: a camera that glides through the world, and a border only one player has.

command /intro:
    players only: true
    trigger:
        set {_from} to player's location offset by 0, 20, -30
        set {_to} to player's location offset by 0, 6, -6
        move camera of player from {_from} to {_to} over 6 seconds looking at player's location
        wait 6 seconds

While the camera has a player they are a spectator and cannot move themselves. When it is over they are put back where they stood, in the game mode they had. The same happens if they log out in the middle, or the server stops: nobody is left a spectator far from home.
The camera does not wait: the lines after it run at once. Follow it with wait for as long as it takes, as above, when the next thing should happen at the end.
A border of one's own is only drawn, like a fake block: it stops the player walking through it but the server does not enforce it. It lasts until it is reset or they change world or log out.
