The name of this macro is «Automatic Watermelon Farm in the Hypixel Skyblock game». For it to work, you will need to install the «CmdKeybinds» mod or any other macro mod, as well as bind the macro to the «Delete» key. 

Before starting the macro, make sure that you are on the Hypixel Skyblock island and set the spawn point with the command «/setspawnlocation» with the angle at which you will farm. 

The farm consists of three rows with three separate sections, with a total length of 192 blocks in each row. 

For the macro to work, the dude (your character) will move first to the left, then to the right and then to the left again to move to the next section of the farm. 

It is also important to install blocks at the end of each section of the farm so that your character does not escape from the farm, but continues to move in the next direction. 

After installing and binding the macro to the «Delete» key, you just need to press this key to activate the macro and automatically start the watermelon farm in the Hypixel Skyblock game.
