This is how you can make a Squadron of Fighters buildable.
First open up a Space Unit XML EX: Zsinj, Remnant_Space_Units.
Ill use the Tie Raptor as an example.
Change this Under the Tie_Raptor not the Squadron
<Hyperspace>no</Hyperspace>
<Hyperspace_Speed>0</Hyperspace_Speed>
to this
<Hyperspace>yes</Hyperspace>
<Hyperspace_Speed>1</Hyperspace_Speed>
(Edit the speed to how fast you want it to hyperspace).
Now for the Tie Raptor Squadron
Change this
<Required_Star_Base_Level>0</Required_Star_Base_Level>
<Build_Tab_Space_Units>No</Build_Tab_Space_Units>
<Build_Initially_Locked>Yes</Build_Initially_Locked>
to this
<Required_Star_Base_Level>1</Required_Star_Base_Level>
<Build_Tab_Space_Units>Yes</Build_Tab_Space_Units>
<Build_Initially_Locked>No</Build_Initially_Locked>
Hope this helps.
How do you edit this in the XML? When I open it up it is locked and I cannot change it. When I selected edit it bought everything up in notepad, but did not allow me to save the changes. I've never done anything like this before and would like make the changes.
