[Tutorial] How to block rebirth on some area

[mar]

Let's say u want to block scroll of rebirth in castle (castle war).
We cant do this in standard way, so we have to change revival function. Idea: add function which will be called from revival function that control Player's X,Y and compare them with coordinates of forbidden area.

Symbols in this guide:
-PX,PY - player's X, player's Y
-X1,Y1 - south-west left corner of area where u cant use rebirth
-X2,Y2 - north-east corner of area where u cant user rebirth

Function:
if PX<X1 -> rebirth works
if PX>X2 -> rebirth works
if PY<Y1-> rebirth works
if PY>Y2 ->rebirth works
else rebirth doesn't work (PX and PY is in our area)


Ok, let's start modifications - everything is in MainSvrT.exe


1) Open it in hexeditor, (for ex. xvi32)
-Make bypass of revival function - (On start function jmp to our procedrue) - Go to offset 1FFA3 and replace bytes to:

E9 B8 AA 0B 00 90 90 90 90 90 90 90 90 90 90 90 90 90 90


-Make our function. Goto offset daa60 (empty area) and change bytes (overwrite) to:

8B 45 08 81 B8 4C 01 00 00 C0 C1 03 00 72 29 81 B8 4C 01 00 00 80 DE 03 00 77 1D 81 B8 50 01 00 00 00 E1 03 00 72 11 81 B8 50 01 00 00 C0 0D 04 00 77 05 E9 1E 55 F4 FF 51 89 4D FC 8B 45 FC 8B 48 04 51 8B 4D 08 E8 A5 9E F8 FF E9 06 55 F4 FF

This is our function. It looks like:
mov eax,[ebp+08]
cmp [eax+14c], X1 <- check PX with X1
jb out_of_area <- jump if below
cmp [eax+14c],X2 <-check PX with X2
ja out_of_area <- jump if above
cmp [eax+150], Y1 <- check PY with Y1
jb out_of_area
cmp [eax+150],Y2 <-check PY with Y2
ja out_of_area
return from function (we are in area, jump back into end of revival function)
out_of_area: commands from orginal revival function.


2) Save, close. It's done

[nosseir63]

thx alot...it work
only one point needed....when u die in the castel Area....u back to your revive city very fast.... i mean if the time become 2 minuts will be better....cuz u maybe get revive by a mage in your guild in War

cause it was an unnecessary rebirth effect when rebirth was blocked and 1 rebirth was taken i decided to correct it, so overwrite all bytes at offset daa60 into:

8B 45 08 81 B8 4C 01 00 00 C0 C1 03 00 72 2E 81 B8 4C 01 00 00 80 DE 03 00 77 22 81 B8 50 01 00 00 00 E1 03 00 72 16 81 B8 50 01 00 00 C0 0D 04 00 77 0A B8 00 00 00 00 E9 19 55 F4 FF 51 89 4D FC 8B 45 FC 8B 48 04 51 8B 4D 08 E8 A0 9E F8 FF E9 01 55 F4 FF 00 00

Now, when you die in forbidden area, you wil not loose rebirth scroll and there will be no rebirth effect

Does this have to be hex edited after kosp is applied or before?

doesnt matter

All the KOSP patch does, is changing 1 dll name into another inside your mainsvr...

[DJBL]

Problem is if i edit (hex editor is HxD) then the mainsrv.exe becomes inoperationable

[General]

you need to replace bytes, not add ;p

[DJBL]

ok that worked, but mainsrv now closing when someone uses rb

[Mr.wagdy]

yay its work !

thank's :)

[samsam]

When i use any rb on any place i got CL + mainsvr close hmm

any one have any idea?
