GDF won't add a modifier, how to set modifier levels

[zuljita]

Trying to write up Gurps Thaumatology - Sorcery as a GDF, I'm not a coder by nature, but I need this for a campaign, and would like to contribute to the community while I'm at it. I also see this as a learning project. two issues:
**EDIT** Figured out 1), was missing some spaces. the question 2 still stands.
1) I'm not getting one of the modifiers on a spell (no blunt trauma) when I add the AD (Air jet)

Air Jet, 0, displaycost(6/12/18), page(Thaumatology - Sorcery 12), cat(Sorcerous Spells),
	adds(_
		"AD:Crushing Attack (Air Jet)" _
			with "Jet, +0%, group(_Attack Enhancements),page(B106)"_
			and "No Blunt Trauma, -20%, group(Crushing Attack Limitations),page(B111)" _
			and "Damage Limitation: No Wounding Except Vs Diffuse, -25%, group(_Attack Limitations),page(B111),basedon(Damage Modifier: Missing Damage Effect (type)),basedgroup(_Attack Limitations)" _
			and "Blockable, -5%, group(_General),page(P110)" _
			and "Cosmic: Does knockback-based damage against diffuse targets, +50%" _
			and "Damage Modifier: Double Knockback, +20%, group(Crushing Attack Enhancements),page(B104)" _
			and "Jet: Increased Range, +10%,group(_Attack Enhancements), page(B106)" _
			and "Jet: Increased Range (1/2D Range Only), +5%,group(_Attack Enhancements), page(B106)" _
			and "Sorcery, -15%, group(_General),page(Thaumatology - Sorcery 13)" _
			respond 3 _
		), parentof(AD:Crushing Attack (Air Jet))

2) In a similar advantage, I'm trying to write up using with "modifier, ..." but I want to add it at a level, what argument and where do I need to put it in that string?

Related question: If i want to tell the above style of code to pick an attack attribute for affliction when it's added, how do I do that?

Level would be the first thing, before the "with" statement. So:
"AD:Crushing Attack (Air Jet)" = 3 _
with "yada yada yada"

What do you mean pick an "attack attribute?" Do you mean how do you select which skill/attribute is rolled against to make the attack? It's the same as with Innate Attack, except there are a couple more respond numbers you can use (Innate Attack uses 1-7, while Affliction uses 1-12) .

*respond 1 for _None of these
*respond 2 for Will
*respond 3 for DX, Brawling
*respond 4 for Innate Attack (Beam)
*respond 5 for Innate Attack (Breath)
*respond 6 for Innate Attack (Gaze)
*respond 7 for Innate Attack (Projectile)

*respond 8 for Based On HT
*respond 9 for Based On ST
*respond 10 for Based On IQ
*respond 11 for Based On DX
*respond 12 for Based On Perception

That's awesome. What about setting levels for limitations, ex: increased range 4 or what have you?

You just need to add the level() tag to the modifier, placing the level number within the tag.

Awesome, thanks!

Another thing I just noticed: Adding Jet using the above code doesn't add the version of Jet that exists from the basic set GDF, it adds a new one, that doesnt give

-3 to owner::acc, *0.5 to owner::rangehalfdam, *0.1 to owner::rangemax, =nobase to owner::rof$, ="Jet" to owner::rof$

Do I need to declare that stuff when i write this code, or is there something else I'm missing?

With modifiers you need to specify the entire modifier, declaring everything. I usually just copy the modifier right out of the appropriate data file to make sure I've got everything.

Thanks. Is this the best practice way to do this? Just wanting to make sure I'm not doing this the long difficult way needlessly. I don't mind doing it this way at all if it's the best practice, just want to confirm.

It's the only way to do it if you want the modifiers to actually change the stats of the underlying ability.
