[Development] Adding Effects to Items (Easy Way)

Kiosani · Jun 18, 2014

Well, I now have a much better method than this, so I made this for those who want to learn something interesting..

First thing to understand: Formulas for calc "ItemID" and "ObjectID"

for ItemID is: #define ItemId(x, y) ((x * 512) + y)

Small explain:

x = item type get of your: Item(XXX).txt from server side
y = item index get of your: Item(XXX).txt from server side
512 = is max item index possible on: Item.bmd from client side

For example:

for calculate ItemID for item: "Divine Sword of Archangel" you must apply the Formula

Divine Sword ItemId = 0 * 512 + 19 = 19 (This value must be passed to hexadecimal: 0x13)

then: 0x13 is ItemId for: Divine Sword of Archangel (on any main.exe version more than: 1.01 series)

but, for example for calculate ItemID for: "Wings of Storm" of Blade Master:

Wings of Storm ItemId = 12 * 512 + 36 = 6180 (This value must be passed to hexadecimal: 0x1824)

then: 0x1824 is ItemId for: Wings of Storm (of course than on any main.exe more than: 1.01 series, and in main.exe from versions more old not exists this wings

)

for ObjectID is: #define ObjectId(x, y) ((x * 512) + y + ItemArray)

Well is the same.. but have 1 aditional factor: ItemArray?? is very simple to find for any version of main.exe, in my case is: 834 (in decimal value) but in hexadecimal value is: 0x342

Small Guide to find: "ItemArray" in any main.exe (more than: 1.01 series)

http://forum.ragezone.com/f508/item-smoke-effect-868154/

Well then to calculate our ObjectID for each case of Item:

for example: Wings of Storm ObjectID = 12 * 512 + 36 + 834 = 7014 (in decimal value but passed to hexadecimal value is: 0x1B66)

then: 0x1B66 is ObjectID for: Wings of Storm in own main.exe version: 1.03.11 JPN

with main.exe open in ollydbg -> second click -> search for -> all constants and write: 1B66

Dz7gPDV - [Development] Adding Effects to Items (Easy Way) - RaGEZONE Forums

the function allocated on: 005CFAC0 is the function for identifier: Wings of Storm and Render Sprites and Effects on this..

Well here a Individual part of code for understand..

Code:

void __declspec(naked) WingsOfStormEffect(){
    _asm
    {
        MOV EAX, DWORD PTR SS:[EBP+0x0C]
        MOV dwItem, EAX


        CMP dwItem,[COLOR=#ff0000]ObjectId(12,36) //Original case for Wings of Storm item[/COLOR]
        JE Return


        Return:
        MOV ECX,0x005CFAC7
        JMP ECX
    }
}

then.. If you add your own item to this Assembler Inline function re-writed of 1 asm Line of main.exe, and you put on your added item like: .smd the same count of Bones or Nodes, and convert to: .bmd, put on your client folder ussually: "Data/Item", and hook your compiled: Nemesis.dll to your: 1.03k JPN main.exe, you can see something like this:

PS 1 :
Sorry for put the same effect on this Staff you must add your item case ObjectID in: WingsOfIllusion Inline function of my code and usage this model:

You must be registered to see links

PS 2 :
For create your own items using this method of: "COPY" of original Wings 3 Effects every one of your added models .bmd must have exactly the same: counts of: Bones or Nodes, than original Wings Models effect, because main.exe get bone positions for calculate the effect lights positions.

Example with: Staff of Angel .smd:

Code:

version 1
nodes
0 "Box01" -1
1 "Bone01" 0
2 "Bone02" 1

end

38 is Bone count on: Wings of Illusion original one item than get this effects.

Credits for this: ONLY FOR ME (I create this method, like 1 easy way to render cool lights on Items)

And this is like Small Guide for noobs, because people with more knowledge, they may think that this is a silly method, but silly.. or not silly, this method works.

Very interesting, Thanks for sharing I am the first to comment XD :tongue:

walter29 · Jun 20, 2014

Excelente,surely will help a lot

walter29 · Jun 21, 2014

I downloaded your code to analyze me and I noticed that you put the offsets of the wings ..
If I wanted to apply these effects in a wing custon, where in the code I put the id of this wing custon?

        [COLOR=#008000]CMP dwItem,ObjectId(12,XX) //XX = your Wings Index get of your: Item(kor).txt file
        JE Return[/COLOR]

        CMP dwItem,[COLOR=#ff0000]ObjectId(12,36) //Original case for Wings of Storm item[/COLOR]
        JE Return


        Return:
        MOV ECX,0x005CFAC7
        JMP ECX
    }
}

PS: is easy.. but remember that your custom model wings must have the same count of Bones, that original Wings model of the Effect.

walter29 · Jun 22, 2014

mauro07, analyzing the code again I realized that the offsets to find the two using the formula:

for example: Wings of Storm ObjectID = 12 * 512 + 36 + 834 = 7014 (in decimal value but passed to hexadecimal value is: 0x1B66)

as shown in the image below:

cZob7iR - [Development] Adding Effects to Items (Easy Way) - RaGEZONE Forums

Thus I wonder then what the need to seek the ItemID as in the example below? :

Wings of Storm ItemId = 12 * 512 + 36 = 6180 (This value must be passed to hexadecimal: 0x1824)

In that part of the offset or hexa this item fits in code?

and that number 5 after the offset refers to what?

void WingsLevel3EffectsHook()
{
SetNop(0x005CFAC0, 5);
WriteJmp(0x005CFAC0, (DWORD)&WingsOfStormEffect);

From already thank you very much for your attention.

debugged from 1.03.11 jpn, this are: Bones from: Wings of Storm by: BoneId :lol:

and this:

Search ItemID, at least for add Sprites on items.. not is necessary.. but I explain this, because in server side (gameserver), the formula used is: ItemID to find all procs related to Wings (for example), for make fixes. and main.exe use: ItemID formula for some another importants special properties from: Items.. in character inventory view for example.

5 is count of nops for the function: SetNop, because.. in this code I make a JMP from: main.exe code (to) -> Nemesis.dll re-writed code and again from: Nemesis.dll code (to) -> main.exe normal load code..

This code replaces that line of code in the main, by the content of the function in in-line assembly: WingsOfStorm, then the sum of the memory address in the main.exe which is no longer used must be annulled by the function in this case called: SetNop.

I think that you must learn more about assembler :lol:

walter29 · Jun 22, 2014

Yes friend you are absolutely right, I have to learn more about assembler ^ ^ I'm pretty novice in this area of programming of muonline, I am venturing to learn this because I found very interesting to add effects to items, I am very thankful to be sharing and also giving support for us.

Sword Breaker case 861 of switch

Formula for calc ObjectID from Sword Breaker: 0 * 512 + 27 + 834 = 861 (in decimal value)

walter29 · Jun 24, 2014

mauro07,I tried to use the effect of item Chaos Dragon Axe on a custon mace, but it does not work out, because I do not know if it was because I put the wrong offset ...
for example: Chaos Dragon Axe ObjectID = 2 * 512 + 6 + 834 = 1864 (in decimal value but passed to hexadecimal value is:748)

I found these offsets as shown in the image below, but I'm not sure which one is right:

Li3iZTY - [Development] Adding Effects to Items (Easy Way) - RaGEZONE Forums

Chose the offset that the arrow is pointing to your code and added these lines:

void __declspec(naked) ChaosDragonAxeEffect()
{
_asm
{
MOV EAX, DWORD PTR SS:[EBP+0x0C]
MOV dwItem, EAX

CMP dwItem,ObjectId(2,30)
JE Return

Return:
MOV ECX,0x005BFE5D
JMP ECX
}
}
void __declspec(naked) WingsOfStormEffect()
{

void WingsLevel3EffectsHook()
{
SetNop(0x005BFE56, 5);
WriteJmp(0x005BFE56, (DWORD)&ChaosDragonAxeEffect);

SetNop(0x005CFAC0, 5);
WriteJmp(0x005CFAC0, (DWORD)&WingsOfStormEffect);

SetNop(0x005D008B, 5);
WriteJmp(0x005D008B, (DWORD)&WingsOfVortexEffect);

Now I do not know if wrong in choosing the correct offset or if I did something wrong in the code, since the effect did not work :/:

bad function hook man! I think that your correct function is: 0x004F69FB, look better in your screenshot

CMP DWORD PTR SS:[EBP-0x4CC],0x748

PS: YOUR FUNCTION IS BAD!, you must restore original EBP-4CC case in your code:

void __declspec(naked) ChaosDragonAxeEffect()
{
_asm
{
MOV EAX, DWORD PTR SS:[EBP-0x4CC]
MOV dwItem, EAX

CMP dwItem,ObjectId(2,30)
JE Return

Return:
MOV EAX,0x005BFE5D
JMP EAX
}
}

you must try to use the original register to restore section look this:

BECAUSE THIS OFFSET: 004F6A05 MAKE A JUMP WITH CONDITIONAL TO: 004F7E36 |> \C685 88FDFFFF MOV BYTE PTR SS:[EBP-278],0

CALL 004CC40E IS CALL TO GETBONEID FUNCTION
FLD DWORD PTR DS:[596ABD8] IS STATIC CALL TO WORLDTIME FUNCTION
CALL 004A1F10 I DON'T KNOW..

004F7EE6 |. 6A 00 PUSH 0 //unk
004F7EE8 |. 6A 00 PUSH 0 //this is bone id

PUSH 7D62 IS EFFECT TEXTURE

CALL 006BABF2 IS CALL TO DRAW EFFECT IN SCREEN

tried to change the code here but I had no success, I'm already with the whole mind messy here so much I need to understand, I have to give a good asm studied in order to understand better, because it is very complex to me kkkkk

thank to nemis and mauro07....I love forum...(^_^)...

yeah works with any main.exe version, you only must research offsets for every function, fix registers and test! xD

PS: I can make for 1.04d GMO main.exe too, without extrange bugs and 100% usable, If you like wait for my release, maybe in 1 hour, I can have ready 1 interesting code for u man.
