  The Mission Director (MD) is a subsystem of the game and interprets mission scripts, which are written in an XML-based language. The Mission Director in X Rebirth and X4 is based on the MD in X3: Terran Conflict, with some major changes based on feedback from MD users.\\
--An introduction to the original MD can be found in the[[(% &text-decoration: underline;" %)Egosoft forums>>url:http://forum.egosoft.com/viewtopic.php?t=196971]](%%). There is also a PDF guide for the X3 Mission Director, which is partially used as a template for this document.

  To collect all messages in a file, start the game with the following parameters on the command line:

++{{code language="xml"}}-logfile debuglog.txt{{/code}}
  All messages, including enabled non-error messages, will be written into the log file. You can find it in your personal folder, where your save folder is located. To enable scripting-specific debug messages, add the following to the command line:
--{{code}}-debug scripts{{/code}}

  Cancelling a cue with **<cancel_cue>** also cancels all its sub-cues, and cancelling a static cue stops it from instantiating more cues - but it does not cancel its instances. Resetting a cue with **<reset_cue>** resets both sub-cues and instantiated cues, but has the (desired) side effect that condition checks will start again if the parent cue's state allows it. Even a sub-instance that has been reset can return to the //waiting// state. Resetting an instantiated cue will stop it forever, because it is not supposed to be in the //waiting// state (only its static cue is). Resetting will also induce the clean-up reliably, but keep in mind that this is not the case for instance sub-cues.

  There is a way to convert a number into a different type manually: You append the corresponding suffix to a sub-expression in parentheses, like this:
--* {{code}}(1 + 1)f{{/code}} ⟹ {{code}}2f{{/code}} ⟹ {{code}}2.0{{/code}}
--* {{code}}(1h) m / (180deg) i{{/code}} ⟹ {{code}}(3600s) m / (3.14rad) i{{/code}} ⟹ {{code}}3600m / 3{{/code}} ⟹ {{code}}1200m{{/code}}

--When converting to a non-default unit type, this means you interpret the number as in the given units: "{{code}}(1km + 500m)h{{/code}}" means that you interpret 1500m as 1500 hours, so the resulting value will be 1500x3600 seconds. (As stated above, the default unit for a length is metres.)
++When converting to a non-default unit type, this means you interpret the number as in the given units: "{{code language="xml"}}(1km + 500m)h{{/code}}" means that you interpret 1500m as 1500 hours, so the resulting value will be 1500x3600 seconds. (As stated above, the default unit for a length is metres.)
  The division operation will be an integer division (rounding towards zero) if both operands are integers (see the example in the table above). So if you want to get a floating point result, you have to make sure that at least one of the operands is a floating point type.
  Every data type can be combined with a string with the + operator, and will be converted to a string representation. That way you can also concatenate strings and numbers:
--* {{code}}'One plus one is equal to ' + (1+1) + '.'{{/code}} ⟹ {{code}}'One plus one is equal to 2.'{{/code}}
--* {{code}}'One plus one is not equal to ' + 1 + 1 + '.'{{/code}} ⟹ {{code}}'One plus one is not equal to 11.'{{/code}}

++* {{code language="xml"}}'One plus one is not equal to ' + 1 + 1 + '.'{{/code}} ⟹ {{code language="xml"}}'One plus one is not equal to 11.'{{/code}}

  If you look up a property that does not exist, there will be an error, and the result will be null. To test whether a property exists, you can append a question mark "?" to the lookup, which yields true or false:
--* {{code}}$list.{5}{{/code}} ⟹ The fifth element of a list - however, if $list has less than 5 elements (and if it's also not a table with the key 5), there will be an error
--* {{code}}$list.{5}?{{/code}} ⟹ true if $list exists and has the property 5, false otherwise

++* {{code language="xml"}}$table.$key?{{/code}} ⟹ Analogously, true if $table exists and has the string property '$key'\\
  The question mark can even be applied to variables:
--* {{code}}$list{{/code}} ⟹ The value stored under the name $list, or an error if there is no such variable
--* {{code}}$list?{{/code}} ⟹ true if the variable exists, false otherwise
++* {{code language="xml"}}$list{{/code}} ⟹ The value stored under the name $list, or an error if there is no such variable
++* {{code language="xml"}}$list?{{/code}} ⟹ true if the variable exists, false otherwise
  To look up the value of a property although it may not exist, you can use the at-sign "@" as prefix:
--* {{code}}@$list.{5}{{/code}} ⟹ The result of the $list lookup if $list exists and has the property 5, otherwise null (without error message)
--* {{code}}@$list{{/code}} ⟹ The list if this variable exists, null otherwise
--* {{code}}@$list.{5}.{1}{{/code}} ⟹ The first element of the fifth element of $list, if it exists, null otherwise
++* {{code language="xml"}}@$list.{5}{{/code}} ⟹ The result of the $list lookup if $list exists and has the property 5, otherwise null (without error message)

++* {{code language="xml"}}@$list.{5}.{1}{{/code}} ⟹ The first element of the fifth element of $list, if it exists, null otherwise
  As you can see, an error is already prevented if any link in the property chain does not exist. But use the @ prefix with care, since error messages are really helpful for detecting problems in your scripts. The @ prefix only suppresses property-related error messages and does not change any in-game behaviour.

  Cues can have **<patch>** elements with actions that will be performed when an old savegame is loaded.

  There are many conditions and conditional actions that require a value comparison, for example the condition <check_value>:

  If an action requires a value, e.g. when you set a variable to a value, you can have some randomisation. To specify an exact value, e.g. in <set_value>, you can write this:

++{{code language="xml"}}
++  <set_value name="$foo" min="-20" max="20"/>

  min and max have to be compatible number types. Enumeration types are not allowed, not even level and attention. The min attribute is optional and defaults to 0 (of the number type used in max).
  You can select one of 5 different probability distribution profiles for the random range, "flat" being the default (all values in the range are equally likely). If you select another profile, e.g. "increasing" to make higher numbers more likely, you also have to specify a scale value (integer) that is greater or equal to 2. Higher scale values result in higher peaks in the distribution profiles (probable values become even more probable).

  You can create variables with certain actions and conditions, such as the <set_value> action:
--{{code language="xml"}}<set_value name="$foo" exact="$bar + 1" />{{/code}}
++{{code language="xml"}}
++  <set_value name="$foo" exact="$bar + 1" />
++{{/code}}
  <set_value> also exists as a "condition", which can be useful if you want to pass information about the conditions to the actions, that would otherwise be lost - like in a complex <check_any> event condition, where you want to create a variable only if you are in a certain check branch. (Other pseudo-conditions are <remove_value> and <debug_text>.)
  The default operation of <set_value> is "**set**", but there are more: "**add**", "**subtract**", and "**insert**". //add// and //subtract// change the value of an existing variable, which is created as 0 if it didn't exist before. If neither //min//, //max// nor //exact// attribute is provided, an exact value of 1 is assumed.
--{{code language="xml"}}<set_value name="$foo" operation="add" />{{/code}}
++{{code language="xml"}}
++  <set_value name="$foo" operation="add" />
++{{/code}}
  The trick is that <set_value> not only works on variables, but also on list elements and table keys:
--{{code language="xml"}}<set_value name="$list.{1}" exact="42" /><set_value name="$table.$foo" exact="42" />{{/code}}\\
++{{code language="xml"}}
++  <set_value name="$list.{1}" exact="42" />
++  <set_value name="$table.$foo" exact="42" />
++{{/code}}
  The operation //insert// is special, and it only works on lists. It inserts the value at the specified position (note that the position beyond the last element is also valid here):
--{{code language="xml"}}<set_value name="$list.{1}" exact="42" operation="insert" />{{/code}}
++{{code language="xml"}}
++  <set_value name="$list.{1}" exact="42" operation="insert" />
++{{/code}}
  This shifts the positions of all following elements up by one. If min/max/exact are missing, the default value is null for insertions, not 1 like in other cases.
  Appending is easier than that. The following actions are equivalent:
--{{code language="xml"}}<set_value name="$list.{$list.count + 1}" exact="42" operation="insert" /><append_to_list name="$list" exact="42" />{{/code}}
++{{code language="xml"}}
++  <set_value name="$list.{$list.count + 1}" exact="42" operation="insert" />
++  <append_to_list name="$list" exact="42" />
++{{/code}}
  Inserting at a position below 1 or above $list.count + 1 is not possible.
  To remove variables or list/table entries, use <remove_value>:
--{{code language="xml"}}<remove_value name="$foo" /><remove_value name="$list.{1}" /><remove_value name="$table.$foo" />{{/code}}\\
++{{code language="xml"}}
++  <remove_value name="$foo" />
++  <remove_value name="$list.{1}" />
++  <remove_value name="$table.$foo" />
++{{/code}}
  Removing an entry from a list shifts all following elements down by one. If you want to clear an entry without removing it from the list, just use <set_value> instead.
