Every map XML file starts with the XML header and then the base <map> module.

Define two teams, their colors and names.

<teams>
    <team id="red-team" color="dark red" max="12">Red Team</team>
    <team id="blue-team" color="blue" max="12">Blue Team</team>
</teams>

Specify where the previously defined teams will spawn. Both teams have two spawn cylinders, players will spawn in one at random at a random location inside the cylinder. We also specify what kit the players will get when spawning. The kits are defined further down in the maps XML file and are referenced here by name.

The direction a player faces when spawning in a region is defined by putting the region inside a <spawn> element and specifying the yaw="" attribute.

<spawns>
    <spawn team="red-team" kit="red">
        <point yaw="-45">
            <cylinder base="-619.5,11,259.5" height="0" radius="2"/> <!-- West -->
        </point>
        <point yaw="45">
            <cylinder base="-571.5,11,259.5" height="0" radius="2"/> <!-- East -->
        </point>
    </spawn>
    <spawn team="blue-team" kit="blue">
        <point yaw="-135">
            <cylinder base="-619.5,11,349.5" height="0" radius="2"/> <!-- West -->
        </point>
        <point yaw="135">
            <cylinder base="-571.5,11,349.5" height="0" radius="2"/> <!-- East -->
        </point>
    </spawn>
    <default yaw="-90"><cuboid min="-544,13,302" max="-540,13,306"/></default>
</spawns>

The objective of the map, in this case a monument made out of obsidian. Both monuments get assigned a owner="" which specifies who’s team it belongs to. The team who destroys the enemies monument first wins.

<destroyables name="Monument" completion="100%" materials="obsidian">
    <destroyable owner="blue">
        <cuboid min="-596,10,361" max="-595,12,362"/>
    </destroyable>
    <destroyable owner="red">
        <cuboid min="-596,10,247" max="-595,12,248"/>
    </destroyable>
</destroyables>

Filter for ice blocks, applying this filter to a region with block-physics prevents ice from melting naturally.

<filters>
    <deny id="deny-icemelt">
        <material>ice</material>
    </deny>
</filters>

The regions of the map. Here we specify a rectangle region with playable as its ID and apply the deny-icemelt filter. We also specify the team base regions and apply a filter to prevent all players from breaking blocks inside the base. Additionally we create a variable height build limit using a region combination.

<regions>
    <rectangle min="-635,232" max="-556,377" id="playable" />
    <apply block-physics="deny-icemelt" region="playable"/>

Each team kit has leather armor colored in their team color and they inherit the main spawn kit.

Specify that stone swords, diamond pickaxes, iron axes, and bows get repaired when dropped or when the player picks one up.

    <tool>iron axe</tool>
    <tool>bow</tool>

Remove arrows, leather armor, wood, apples and obsidian when it is dropped. Items that get dropped from block–break actions also get removed.

Close the main <map> module.
