Rising Star is a short campaign focused on a single Star of Clan Ghost Bear Mechwarriors. Set during the Clan Invasion, you invade primarily FRR controlled worlds. It is lore-referential, but I am not (nor did I consult) a Battletech Lawyer so lore adherence is spotty and apocryphal at best. Currently there are 7 levels, 3 of which are admittedly fairly barebones.

This is my first time doing anything Mech Commander related, my experience with this sort of thing is primarily in the Doom engine, so there is a degree of learning as I go evident in the levels. There are purchase files for each mission, one mission has salvage files, most missions have non-default warrior brains, only 2 of the missions have elaborate enough scripting to warrant a mission brain. In particular I am proud of mission 4.

Levels are as follows:
RS_1_1: A scouting patrol on Nyserta.
RS_1_2: Battle against FRR forces in the desert plains of Thule.
RS_1_3: A trial against a rival star of Clan Mechwarriors on the moon Ultima.
RS_1_4: Link up with the lone survivor of a Star to attack forces in Misby Flats on Trondheim.
RS_1_5: Choke the supply lines to a fortified position on Last Resort.
RS_1_6: Destroy a series of garrisoned bases and capture or destroy mobile orbital guns in fjords on Jezersko.
RS_1_7: Capture and defend bases in Apache Canyon on Goito.

This covers battles leading up to the death of Leo Showers, down the line I want to make a second episode of similar length dealing with the invasion corridor through Tukayyid.

MechCommander OmniTech / Patrol/Movement brain not responding to fire, any elegant solution?

« Last post by Hambourgeois on November 30, 2025, 01:51:12 pm »

Hello potentially dead forum,

I am having an issue with a mission I am working on. I have a mission brain set up to change the warrior brain of a bunch of mechs and vehicles to a patrol brain to move toward a base when you either (a) capture the base HQ or (b) approach the starting point of the relevant vehicles (will probably also add (c) when the base defenders are all destroyed). The movement part is working for both conditions currently implemented, however, when you attack this force en route to the base it does not respond to fire and does not return fire.

Unless I figure out a more elegant solution, I will probably just set them to have an escort brain targeting a Mobile HQ or similar, non-combat vehicle, have a wide scan range to ensure they are ahead of it if the player mechs approach, and just set the movement brain to the Mobile HQ (or whatever).

I have tried the original approach with both a basic patrol brain derived from the original MC2 warrior brains, and one using the universal warrior brain and both have the same problem. Not really a strong coder so if anyone knows of a more elegant solution in .abl I am all ears, otherwise just gonna move ahead with this.

FWIW here is the patrol brain from my most recent attempt:
