1 1  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.\\

201 201  Note that the MD script language is not designed as a programming language. The actions are performed in sequence, although they can be nested to form more complex structures. Loops and conditionals exist to some extent, but not necessarily in the sense that a programmer might expect. Analogously to <check_all> and <check_any>, you can use **<do_all>** to perform all the contained sub-node actions, and **<do_any>** to perform only one of them. <do_all> is particularly useful when nested in a <do_any>.

The simplest case is an instantiating cue with no sub-cues: The instance is created, the actions are performed, and the instance is removed immediately on completion. A pitfall could be an instance with a sub-cue that is forever in the waiting state (e.g. waiting for an event from an already destroyed object).

382 382  In expressions, you can use the cue property **static** to access the static cue that instantiated a cue. This does not work for sub-cues of other cues, and the result is not necessarily a real static cue! In the example above, it would only work for cues with a dotted arrow pointing at them, and is resolved to the source of the arrow. In other cases the result is null.

1169 1169  The trick is that <set_value> not only works on variables, but also on list elements and table keys:
1170 1170  
1171 -{{code}}&lt;set_value name=&quot;$list.{1}&quot; exact=&quot;42&quot; /&gt;&lt;set_value name=&quot;$table.$foo&quot; exact=&quot;42&quot; /&gt;{{/code}}\\
1205 +{{code language="xml"}}
1206 + <set_value name="$list.{1}" exact="42" />
1207 + <set_value name="$table.$foo" exact="42" />
1208 +{{/code}}
1172 1172  
1173 1173  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):
1174 1174  
1175 -{{code}}&lt;set_value name=&quot;$list.{1}&quot; exact=&quot;42&quot; operation=&quot;insert&quot; /&gt;{{/code}}
1212 +{{code language="xml"}}
1213 + <set_value name="$list.{1}" exact="42" operation="insert" />
1214 +{{/code}}
1176 1176  
1177 1177  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.
1178 1178  
1179 1179  Appending is easier than that. The following actions are equivalent:
1180 1180  
1181 -{{code}}&lt;set_value name=&quot;$list.{$list.count + 1}&quot; exact=&quot;42&quot; operation=&quot;insert&quot; /&gt;&lt;append_to_list name=&quot;$list&quot; exact=&quot;42&quot; /&gt;{{/code}}
1220 +{{code language="xml"}}
1221 + <set_value name="$list.{$list.count + 1}" exact="42" operation="insert" />
1222 + <append_to_list name="$list" exact="42" />
1223 +{{/code}}
1182 1182  
1183 1183  Inserting at a position below 1 or above $list.count + 1 is not possible.
1184 1184  
1185 1185  To remove variables or list/table entries, use <remove_value>:
1186 1186  
1187 -{{code}}&lt;remove_value name=&quot;$foo&quot; /&gt;&lt;remove_value name=&quot;$list.{1}&quot; /&gt;&lt;remove_value name=&quot;$table.$foo&quot; /&gt;{{/code}}\\
1229 +{{code language="xml"}}
1230 + <remove_value name="$foo" />
1231 + <remove_value name="$list.{1}" />
1232 + <remove_value name="$table.$foo" />
1233 +{{/code}}
1188 1188  
1189 1189  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.

1195 1195  
1196 1196  You can also read and write variables in other cues by using the variable name as property key:
1197 1197  
1198 -{{code}}&lt;set_value name=&quot;OtherCue.$foo&quot; min=&quot;0.0&quot; max=&quot;1.0&quot; /&gt;&lt;set_value name=&quot;md.OtherScript.YetAnotherCue.$bar&quot; exact=&quot;OtherCue.$foo&quot; /&gt;{{/code}}
1243 +{{code language="xml"}}
1244 + <set_value name="OtherCue.$foo" min="0.0" max="1.0" />
1245 + <set_value name="md.OtherScript.YetAnotherCue.$bar" exact="OtherCue.$foo" />
1246 +{{/code}}
1199 1199  
1200 1200  Instead of referencing a cue by name, you could also reference it via a keyword or another variable:
1201 1201  
1202 -{{code}}&lt;set_value name=&quot;static.$counter&quot; operation=&quot;add&quot; /&gt;&lt;set_value name=&quot;parent.$foo&quot; exact=&quot;42&quot; /&gt;&lt;set_value name=&quot;this.$bar&quot; exact=&quot;parent&quot; /&gt;&lt;set_value name=&quot;$baz&quot; exact=&quot;this.$bar.$foo&quot; /&gt;{{/code}}
1250 +{{code language="xml"}}
1251 + <set_value name="static.$counter" operation="add" />
1252 + <set_value name="parent.$foo" exact="42" />
1253 + <set_value name="this.$bar" exact="parent" />

1215 -When the root cue creates $foo, the variable is stored in the Root cue directly. But SubCue and its descendants will also need access to $foo.
