With /setstartpoint, you set the start of the map; the player will be teleported there when entering the server.

With the command /startpoint, the player is teleported to the start of the map (checkpoints are retained)

The /setdifficulty command can be associated with 0 (for peaceful), 1 (for normal), peaceful (is 0), or normal (is 1) to change the difficulty. (The command only replaces the vanilla command.)

/daynight records the time, which means: If it is night and the command is entered, it stays night, this also works with any other (Minecraft) time of day.

Writing out /gamemode creative over and over again becomes annoying after a while while building. That's why there is the command /gm 0, 1, 2 or 3. This command shortens the long command.

The GUI opens after entering the command and allows you to get and control all blocks and commands via the GUI.

As soon as you enter the death block you die

The Jump Block (Level 1) boosts you upwards when you touch it.

Jump Block (Level 2) boosts you upwards as soon as you touch it.

As soon as you touch the jump block (level 3), you will be boosted upwards.

Depending on the direction you are facing, the Boost Block will boost you forward, this also goes up.

By running on the speed block, the player gets a speed 10 boost

You get blindness 1 when you walk over the blindness block

The slowness block gives you slowness 5 as soon as you walk on it

The clear block effect clears your effects from the speed block etc.

The Checkpoint Block sets a checkpoint, as soon as the player dies he is teleported to the last checkpoint reached.
