This is a code snippet which must be part of a mission script.

 

"Here's a way to emulate the IFF system Capt. Gwen was advocating over in the Development forum"

 

<start> 

<create type ="neutral" raceKeys="friendly" hullKeys="cargo" x="10000" y="0" z="50000" name="innocentShip"/>

Hello, Artemis!^ 

We are a completely innocent ship.^ 

Why don't you close to less than 1000m so we can give you some cookies?^
