Hooks are a way to add additional behaviour to the scripts. They are basically custom scripts that are called upon specific events. For example one could define a hook which is called on player connects and then send a message in the in-game chat to greet the new player.

All hooks have to executable files that are either placed in SDTD_BASE/hooks/<name of hook>/<any name>.sh for global hooks that apply to all instances or SDTD_BASE/instances/<name of instance>/hooks/<name of hook>/<any name>.sh for hooks that only apply to that specific instance. The folder <name of hook> has to be in exactly the same case as the hook name column in the table below shows it.

If you want to use the functions of the management scripts in your hook you can add this to the start of your script:

#!/bin/bash
. /usr/local/lib/7dtd/common.sh

An example can be found in the greet.sh hook for playerConnect. Note that you have to use Bash as interpreter for your script if you want to use the script functions!

An example on how to use PHP for hooks can be found ​on the forum.

If you think a hook for another event could be interesting please create a ticket or contact me.
