I don't have access to it on my laptop so I'll have to get it later. It was na @Assert error. Mostly referring to the starbase and it's spawning.

Really sorry I can't get the error now.

Might be because of the trigger, try and set it to OnDelay.

I've explored using the CreateStarbase line a couple of times without success (to my own bemusement), but looking through the files to find an answer to your question, it may have to do with the fact that the stock ability is just that: a single ability with no buff.  I'm guessing the problem has to do with your buffInstantActionType line in the Ability file, which is probably ApplyBuffToTarget.  This is filtering down to the Starbase creation buff, and that's what I'm betting is the problem.

Without looking through the list of modifers I'm not sure what to suggest at the moment, but I'll take a look.

Here's a thought that works out in my head without any testing:

Ability (ApplyBufftoSelf)

\/

Buff 1 (2 buffInstantActiontypes)

\/

buffInstantActionType "ApplyBufftoSelf" > Buff 2a (buffInstantActionType "CreateStarbase")

&

bufInstantActionType"ApplyBufftoTarget" > Buff 2b (buffInstantActionType "ChangePlayerIndextoFirstSpawner")

Now, the CreateStarbase uses AlwaysPerform in the stock files, so I'd stick with that.  I also extended the desired action it to a 2nd level sub-buff because I didn't want it to finish out before the capturing buff, which has to go through the 2nd level sub-buff.  You could always try replacing the 2nd ApplyBufftoSelf with CreateStarbase and see what it does, especially if you want to experiment with OnDelay, but it's up to you. 

Like I said, this is totally theoretically and should would work with nearly any other instant action types, but I'm just not sure about CreateStarbase.  Good luck with it!

P.S.  I'd love to hear some other ideas that people might have, because I'm always looking for cutting edge ability/buff set-ups to incorporate into my own mod.

That's actually a good tip.  Make sure that's set correctly before you try messing around with what I posted earlier.

With that said, however, the success of such a change would depend entirely on the function of the starbase you're trying to create with the ability.  For instance, is this the same type of starbase as the race's normal one?  If so, I bet you'll need an entirely different entity file just for a different creationSourceAbility line.  Which then might lead to other problems, like whether it'll work because the player entity file actually specifies the race's starbase type (a single type, unfortunately).

If it's a different starbase, then there shouldn't be a problem.

Here's the error I get:

Assert @ c:\gs\entrenchment\CodeSource\GS/Entity/EntitySystemHelpers.cpp(678)

sourceAbility->GetIAbilityPtr()->GetDef()->m_buffApplyAction.buffInstantActionType == BuffInstantActionType::CreateStarBase

Assert @ c:\gs\entrenchment\CodeSource\GS/Entity/Interfaces/IBuff.cpp(4405)

allStarBases.Find(def.entityTypeToCreate) != allStarBases.ConstEnd()

Ok this is the error I get. It's kind of odd because I finally got the starbase to spawn. LOL the weird thing is, it doesn't capture the neutral extractor, it spawns a starbase where the extractor should be AHHAH It's kinda cool.

I'm testing what happens when it blows up now. LOL this is actually kinda funny. 

What have you set as the creationSourceAbility to in the StarBase entity? I think that Have to be either the Ability OR the name of the file (so in this case the buff) that contains the CreateStarBase instant action.

Btw, it might be funny for one ability, but try to imagine roughly 100 each acting this way QQ

Good luck, I cross fingers for the sake of your, and ours, sanity

CONGATULATIONS!!!!!!!  Now, I personally would like to know exactly what pieces of the puzzle fit where in order for it to work, if you don't mind.

Sorry 'bout the formatting

When it produces a starbase, does the original frigate disappear like a Starbase Constructor cruiser?  If so, I'm curious as to whether you've tested this out with multiple ships in the same gravity well.  I only ask because a range of 8000 seems a bit excessive considering the range for the ability itself is only 1000.
