So, I tried to tinker around with some of the .lua files... But then I remembered my freeware hex editor sucks ass, and I'm not any good with Hex in the first place. I have some small measure of competence with Lua, but I have no means of reading the files IN Lua. So... Is there any good decompiler or similar program that will allow me to view quest scripts and the like in plaintext? Confused

To whomever designed the map of Mistpeak Valley to look so much more simple than the actual level is: May the Archangel Michael descend from the heavens and plant his boot squarely between your legs for your asshattery.

there is no working decompiler yet
but we have disassembler
you need lua 5
lua.exe ChunkSpy_kvm.lua "scripts\ai\aisetupscript.lua" -o "scripts\ai\aisetupscript.txt"

Ya a decompiler is problematic. This isn't vanilla LUA we're dealing with (Surpise surprise). It's primarily KoreVM with a bunch of other plugins added into it. Like LUA++ and Pluto.

We have a disassembler, but there's still a few quirks that need to be ironed out before someone can take that and turn it into a decompiler. Plus we need someone that's capable of that. And even if I had that skillset I'm really busy with work.

Welp, thanks anyway, then. I guess I'll just have to either wait, or figure out what the fuck I'm doing with a hex editor.

Can I post some of the decompiled scripts? Just for modding and for examples.
I'm not sure because of rule number 4
Quote:
Posting of original game files is strictly prohibited.

they certainly original, but re-written by my hands, so...
basically I decompiled scripts without functions, they are quite simple (if not consider a lot of copy-paste operation)
functions just starts my brain to blow up Sad
btw, can you help me with two of them?

first

and second (not sure if that script used at all)
ai\combatstyles\fable2legacycombatstyles.lua


Pretty sure some of them are still used by Fable III enemies, but not all of them.

EDIT: Also, since there is no file labeled as being combat styles for the Hero, I think it's safe to assume that the Hero's combat style falls under uniquecombatstyles.lua, which makes sense when you consider that your finishing moves are unlocked as you increase in strength and stature, and as a result every set of finishing moves that you can have is unique to each combination of stats.

To whomever designed the map of Mistpeak Valley to look so much more simple than the actual level is: May the Archangel Michael descend from the heavens and plant his boot squarely between your legs for your asshattery.

Can I post some of the decompiled scripts? Just for modding and for examples.
I'm not sure because of rule number 4


Have at it. chunkspy outputs are not original files. Very Happy
I wouldn't even consider rewritten or decompiled scripts original files.

And editing the compiled scripts via hex editor will only take you so far. The only thing I would use it for is to circumvent the DLC checks. Anything else I'd rather just attempt to rewrite it myself. Definitely not for the faint of heart though.

There IS a fable 2 decompiler. Because it doesn't use KoreVM. It's good to take a look at the Fable 2 scripts if you have them handy because a lot of the scripts are the same between the two games. Just compiled between normal lua and koreVM lua.

http://fable2mod.com/forums/forum.php?req=thread&postid= 249

Thankfully, Fable 3 doesn't have a problem with plaintext uncompiled LUA. Otherwise we'd really be screwed.

Yep. We're also kinda lucky that they actually put plaintext, uncompiled lua in copies of certain files. Like scriptactivation.lua.

Which matches this that I know is right

not like this?
CombatStyles.Dog.TargetScoringFunction = function()

end

anyway, this is simple, function code is complicated

Nope there is only one function is that lua. The rest is just command after command, table after table.

Also, if you didn't know already. The scripts in the other gamescript bank contain debug data for locals, and start/stop lines.

Nope there is only one function is that lua.

and it should be in place
CombatStyles.Dog.TargetScoringFunction = function()
	<<function code>>
end

or not?

You're right. My bad.
It should be this:
function CombatStyles.Dog:TargetScoringFunction(attacker_info, target)

end


There "shouldn't" be a difference between the script and script_r other than one contains compiler debug information. Which is REALLY helpful as it contains line information and local variables.

function CombatStyles.Dog:TargetScoringFunction(attacker_info, target)

	local multiplier = 1.0
	local master = Dog.GetMaster(attacker_info.Combatant)
	if master:IsAlive() then
		local master_ranged = Carrying.IsCarryingRangedWeapon(master)
		local target_ranged = false
		if Carrying.IsAvailable(target) then
			target_ranged = Carrying.IsCarryingRangedWeapon(target)
		end
		if master_ranged ~= target_ranged then
			multiplier = multiplier * 5
		end
	end
	if GUI.IsEntityOnScreen(target) then
		multiplier = multiplier * 3
	end
	return multiplier
end

thanks!
it's loaded, but it seems to be not used at all
I place some MessageBox'es and no one is appear...
strange function
btw, works (loaded) in both ways
function CombatStyles.Dog:TargetScoringFunction(attacker_info, target)


CombatStyles.Dog.TargetScoringFunction = function(attacker_info, target)

Ya. Both syntax give the same thing. I just base it off how lionhead has done all their other stuff for consistency sake.

I'll take a look around and see if anything is loading it. You may be right though. Plus, I'm really not sure on the syntax of the rest. The assembly for it is pretty crazy with all the table stuff going on. I'll trust you have it right though because I don't want to figure it out. Razz

Okay, I'm looking at \data\scripts\miscellaneous\carriedactionusescripts\ oncarriedactionusedig.lua

I'm trying to figure out how I would modify it to jump straight from selecting "dig" to showing your loot (skipping the friggin' stupid-long animation every time).

I ran it through KoreVM LUA decompiler (thanks to Keshire!Wink and it spit out the table, but I'm not familiar enough (yet) with how to read it. Can someone point me to an LUA tutorial that would explain how to convert that table into functions, or at least how to read it?

I can guess at bits and pieces (such as, it's pretty easy to see when it's making a logic call and doing if-then actions... I can understand what JMP [246] means, etc.Wink

I'll attach the decompiled code here, in case anyone has time to look at it.

to get it to skip the animation.

Or do I have to leave the first section alone and change subsequent line numbers to reflect their new positions? Or do I have to figure out how to turn this into plaintext LUA code that is more easily modified? (I know... so many questions, so few answers...Wink

Well... I dug a little deeper... I think this is the offending code... now to figure out how to disable it and either recompile it or rewrite it to work without...
