It is unfortunate that the creature can not be replaced in the tower of the besieged castle!

I found another interesting thing. The HOTA Pirate town has a Resource Silo that produces +1 Sulphur. This +1 sulfur is attached to Dungeon Castle! If I change the sulfur in the Dungeon Castle, it will also change in Cove town.

So you already found that their new towns are already hooks for old ones (but probably better than my two new Neutral Towns - because in neutral towns you cannot build)

anyway doing a whole new city was great job

I did neutral towns by using only WoG scripts (based on Era functions) and existing graphics. If anybody wants to do new neutral town for my mod ("Knightmare Kingdoms") please give me graphics in format for town replacement (it would be new anyway, but limited to neutral town limitations). I have two neutral towns already - one which bases on rampart and one which bases on Tower.

Hopefully my post won't be treated like spam, and I need graphics (there would be credits). Sadly there wouldn't be a Cove town in my mod since Cove creators didn't want to share.

There are the offsets for each hero, i didnt find a list like this anywhere, so maybe it wiil be helpful for someone.

Sadly, i was naive and looks like its impossible to change specialisation with hex editor. I hoped that there will be some kinda reference to spec. formulaes and icon.

Actually, you're a little bit late to the party, I guess . I already posted that list in this very thread, here.

A few years ago, I also posted heroes from exe ranks. It was a lot of work! After Xeron, is there still room for 7 heroes that is not exploited?

Campaign Heroes, e.g.

Specialization themselves are hex-editable; see the post by Maurice.

For icons and text, a plugin with 7 hooks will let you change all of them.

If you want to be creative, you can add a few more hooks to change the source of the specialization .def and then you can fully use some of the hidden heroes3 specializations: Diplomacy, Scouting, Learning, Luck, Leadership.

In fact, you can already use them but you would need to edit UN44.def, UN32.def and HeroSpec.txt to see the correct pictures/text. This makes it a bit difficult to share, but for personal use it's no issue.

Dear RoseKavalier!

Transforming the characters of heroes is already going well! We've found new hero types so the original programmer would be surprised! :-)

You are amazed at how professional you are in programming H3 exe! I've realized a lot of things from myself, but I'm still a beginner. There are two things I want to know if you know the answer. Changing the shooting creature from the tower when besieging the castles. Basic units and neutral creatures have a map of their building where they can be purchased. I want the Sharpshooter to have a building on the map, but to the Cerberus, yes.

Thanks for the help!

0x63CFA8 -> Rampart creature ID
0x63CFC8 -> Tower creature ID
0x63CFE8 -> Inferno
0x63D008 -> Necropolis
0x63D028 -> Dungeon
0x63D048 -> Stronghold
0x63D068 -> Fortress
0x63D088 -> Conflux

For HotA: plugin only
*(int*)0x466868 + 32 * town_id = creature_ID;

RoseKavalier, could you help me pls with changing percent of Familiars Channeling ability and Zombies Disease fixed number (-2)?

I find only that 5A24DC (0000002B-familiar) determine which creature has this ability.

Oh, thank you so much for RoseKavalier, that's what I was looking for!

Are you involved in any Heroes 3 project?

The 15 neutral creatures have 15 buildings on the map where they can be purchased. Suppose I put the Sharpshooter in place of the Grand Elf! The Grand Elf will be neutral creatures, but will not have a building on the map. The Wood Elf and the Sharpshooter will also be building.

Nice question for Familiars, answer is a bit complicated for hex editing:


You can read a bit about the workings of this here.

From my understanding, it's roughly this arithmetic: (0x66666667 / 0xFFFFFFFF) / 2 = 0.40 / 2 = 0.20.

This is not straight-forward (at least to me) in order to get any desired effect. Some simple ideas:
you could NOP NOP 0x5A24B0 to double the value to 40%. Or you could overwrite some instructions and have your own instead.
You could also make it a fixed value always by changing the final value stored in EDX, keep in mind spell points are limited to WORD size.

Also, you should edit '05' @ 0x5A2498 to match your new %. In this case 20% of 5 is 1 so any spell cost lower than 5 is being skipped.
e.g. You want only 10% absorption -> make this value 10.

Plugin-wise
@ 0x5A24B9:
spell_cost = *(int*)(c->ebp - 0x68);
result = (do your calculations);
c->edx = result;
return EXEC_DEFAULT;


&&

_PI->WriteByte(0x5A2498, your_new_value);

~~~~~

At first I thought this might be stored in spell info itself, but it's all zeroes.
Unfortunately it seems the value '2' is shared by several other spells @ 0x4446EF so it's probably best to leave it be.

If you use a plugin @ 0x444BF3 you can have:

c->edx = disease_effect;
return EXEC_DEFAULT;

~~~

@peter1985

So basically you want to change town recruitable army ?
If yes, I don't know because I never bothered to look at all requirements - including changing town appearance. Seems to be more a WoG-type of modification.

I'm only involved in my own projects, which take plenty of time
On the plus side, I've now got some really great tools for mapmaking and testing.

Thanks, i did this NOP-change, so its 40% now with 3 instead of 5 as minimum for spell cost. A bit sad that maximum amount of stolen mana is 10, but still much better than in original.

It can be more than that if you want:

e.g. 100%
0x5A24B4
8B 55 98 90 90
// mov EDX, spell_cost

50%
0x5A24B4
8B 55 98 D1 EA
// mov EDX, spell_cost
// SHR EDX, 1 ~ divide by 2

Wow, it worked! I have no idea what it changed, since i just started working with ollydbg, but still. Thanks again from Familiar Union, maybe now they will be more useful.

For the one you quoted: it ignores everything that was done beforehand
and does:

absorption = spell_cost / 2;

local variables (vs. global) are stored on the stack (EBP - 4, EBP - 8, ...) and it so happens spell_cost is stored at (EBP - 0x68), so we just place that in the register that ends up being absorption value (EDX) and then shift right by 1 (move all bits to the right by 1 ~=~ integer division by 2).
11011111 -> 01101111

The blue bit gets shifted into nothing, and we introduce a 0 at the start (green).
11011111 = 223
01101111 = 111
