Have you tried using the palette (Faction Number) command?

Sorry I'm using my phone...

You may have to spawn the palette in the sandbox and start generating ships using that. In the campaign mode, the blocks that show up have to be used in a ship design available for that faction, or something of that nature. I could also be blowing smoke. I've never done any experimenting with this stuff, but I do recall reading some reports to that effect.

Whenever I try to use the palette command to spawn in the blocks, it simply says that faction 155 doesn't have any blocks defined. I tried to make them show up many times, not once did they actually show up.

Finally got around to checking this out ... Very Cool!

Love the visual display for Regions.lua. Can't tell you how much time I spent tweeking those numbers to get the right spawns.

I like the block set-up. I probably wouldn't use it for making a faction with lots of blocks, but I can definitely see using it for planning things out and making the stat-heavy blocks like weapons.
I especially like that you can make a launcher that launches missiles, that fires more missiles, etc. etc. Definitely handy for for making code-heavy blocks like that.

A few things you could possibly add:

There's an ATTACK ai that you can add to factions.lua and to command blocks. This is the tournament ai that attacks, and does nothing else.

In factions.lua, there's a thrustSFX=1 value that can be added to factions. ... Not sure what the actual effect is.

If you look at the faction 3 command module, there's a value for: disruptTime=0.500
Never tested what this does, but assumed it was some sort of AI delay to make faction 3 respond slower.

I think that disruptTime is the delay between a hit and the reassembly of block.
Making the red faster at reassembling.

(I'm gona make a few test and get back to you)
