# Custom Server Changes

## These are the custom integrations possible with dayzdockerserver

### Lowered login/logout time

To lower the login/logout time from the default 15 seconds.

Go into the server container:

```shell
docker compose exec server bash
```

Make a new directory in /profiles/custom called login and go into it:

```shell
mkdir -p /profiles/custom/login
cd /profiles/custom/login
```

Generate a globals.xml with the changed values:

```shell
cat > globals.xml << EOF
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<variables>
    <var name="TimeLogin" type="0" value="1"/>
    <var name="TimeLogout" type="0" value="1"/>
</variables>
EOF
```

### No food

For a more survival-oriented experience, one can prevent food from spawning in the world, forcing players to hunt and fish for food.

Go into the server container:

```shell
docker compose exec server bash
```

Make a new directory in /profiles/custom called no-food and go into it:

```shell
mkdir -p /profiles/custom/no-food
cd /profiles/custom/no-food
```

Generate the types.xml override file from your current mpmissions type.xml (presumes dayzOffline.chernarusplus):

```shell
xmlstarlet ed \
  -s / -t elem -n food \
  -m "/types/type[category[contains(@name, 'food')]]" "/food" \
  -d /types \
  -r food -v types \
  -u //nominal -v 0 \
  /serverfiles/mpmissions/dayzOffline.chernarusplus/db/types.xml \
  > types.xml
```

Always lint any XML file that is created/merged:
```shell
xmllint --noout types.xml
```

Explanation:
* Start xmlstarlet in edit mode
* Add a new XML node at the root named "food"
* Move all `<type>` nodes where `<category name="...` has the word "food" in it to the new /food node
* Delete the remaining `<types>` root node
* Rename `<food>` to `<types>`
* Set all remaining nodes to have `<nominal>0</nominal>`
* Do this for every mpmissions types.xml file (dayzOffline.chernarusplus shown here)
* Save it to a new types.xml file in the current directory, the one we made above.

This file will now serve as a types.xml override for all food items when the server starts!

Every directory under /profiles/custom will be added as a new Economy Core entry when the server is started.
