Component-dependant engines

[Raapys]

I've introduced power reactors to the game, basically just a generic component, and I'm trying to get the engines dependant on it being present for them to work. Since it's not possible to add new 'abilities' from what I could find out, that means I had to use the Get_Design_Specific_Component_Count() function. I first tried putting it in the 'to use' requirement field of the engine without any luck, then I tried using it in the 'movement amount' formula on the engines( i.e. tried setting movement point amount to 0 if no reactor present).

There's simply no way this will work. My two test designs, one with reactor another without, always fly at the same speed. I tried getting a little creative after a while, but alas, reactor or not, it doesn't make any difference between the two ships' speeds. They both fly either 1-2 m/s, or 10 m/s, dependant on how I set up the formula, while I basically want the one with the reactor to fly 10 m/s and the one without to fly 1 m/s( or 0 m/s, but that doesn't seem to be possible).

If it wasn't for my very limited capabilities, I'd say the function didn't work properly making it unable to find the reactor component.

Any ideas?

That function doesn't work on components.

You can have a weird workaround by using the method SJ used in GG for his Crew requirement, though..

One way:

Requirement 5 Description := Ship requires more reactors to properly power its engines.
Requirement 5 Formula := iif(Get_Design_Abilty_Total("Standard Movement") > 2), Get_Design_Abilty_Total_AITAG01 > 1, 1)

You can't use that as-is, because I don't remember the format for the AI tags. What this does is if the number of standard move goes above 2, it requires a reactor before the design can be built. It won't slow down due to battle damage, though.

I tried with a

Requirement 6 Formula := Get_Design_Ability_Component_Count("AI Tag 16") > 0

on the frigate ship type just to test it, but it easily lets me make a ship without it, no warning at all. The reactor component has the "AI Tag 16" ability and everything. *shrug*

[Phoenix-D]

iifs might not work in that file, then. :/ Did you try just the AI tag?

[Raapys]

Uhuh, think I might have made a mistake.

Yah, looks like it's working now, thanks. Would be nice if there could be a function that looked for a specific ability description, so we could just use the 'Description Only' ability instead of wasting the AI tags and such.

Actually, there is. Kwok made much use of it in Balance Mod, such as this "ability" on the SDD:

Ability 2 Type := Description Only
Ability 2 Description := Automatically used if a ship is successfully boarded, destroying the ship and the attacking ship.
Ability 2 Scope := Space Object
Ability 2 Range Formula := 0
Ability 2 Amount 1 Formula := 0
Ability 2 Amount 2 Formula := 0

Something like that would really open up our modding options and eliminate the need for the AI tags.

I was thinking about something like this:
Code:

---

Ability 1 Type                        := Unique String

Ability 1 Description                 := 

Ability 1 Scope                       := Space Object

Ability 1 Range Formula               := 0

Ability 1 Amount 1 Formula            := "UW Basketweaving"

Ability 1 Amount 2 Formula            := 0  

---

Then have a functions like Get_Design_Ability_Unique_String("UW Basketweaving") or some such.

Of course, the best thing would be if we could simply add do-nothing abilities to the Main_Strings.txt file!

There's simply no way this will work.

Do we know functions DO work in the movement formula?

[Phoenix-D]

Oh, they work. The problem is that some functions don't work in components.txt, including the ones you'd need for this trick.

But you can also add abilities directly to ships in vehiclesizes.txt. When I've added movement-generation abilities using formulas to ship hulls, they never work.

For example, Combat Movement with the formulas Get Specific Component Count or Get Design Ability Total do nothing. So problems with the movement formula extend beyond just components.txt.
