Go to mpmissions\dayzOffline.<mapname>\expansion\settings in your server directory and open the file safezonesettings.json

Add the following lines:

    {
        "Center": [
            3728.27001953125,
            403.0,
            6003.60009765625
        ],
        "Radius": 500
    },

• Center is a array where you will need to specify the X Y Z coordinates of your safezone.
• Radius is the size of your safezone (meters).

The easiest method we recommend you to do is to go at the location you want to add your safezone and open your admin tool to get this coordinates.

Think to remove the , in }, at the last bracket.

• Height is the Height of your safezone (meters).

Add the following lines (you have a picture to show how it should be done)

    {
        "Positions": [
            [
                6345,
                140.0,
                2181
            ],
            [
                6198,
                140.0,
                2433
            ],
            [
                6565,
                140.0,
                2945
            ],
            [
                7000,
                140.0,
                2521
            ]
        ]
    },

• Positions is a array where you will need to specify the X Y Z coordinates of your safezone. Since this is a polygon, you need to add multiple positions like in this example to create a polygon shape safezone.

The easiest method we recommend you to do is to go at the location you want to add your safezone and open your admin tool to get this coordinates.

You can also use the DayZ Editor mod if it's easier for you.
