Load NEW Maps Music on .MP3 Source (1.03K) Japan

[Kiosani]

Hello people : today I like share this source... this is not a decompiled source yet, It's only assembler re-writed from main.exe but is easy to understand anyways :

Maps.cpp:

void Naked cMaps::PlayMusic()
{
    static DWORD dwPlayMusic_Call1    = 0x005F7325;
    static DWORD dwPlayMusic_Call2    = 0x005F72E3;
    static DWORD dwPlayMusic_Return = 0x00602545;

    }
}

void cMaps::InitPlayMusic()
{
    gToolKit.SetRange((LPVOID)0x0060250A,59,ASM::NOP);
    gToolKit.SetJmp((LPVOID)0x0060250A,this->PlayMusic);
}

void cMaps::Load()
{
	this->InitPlayMusic();
}

Maps.h:

#ifndef __MAPS_H__
#define __MAPS_H__


class cMaps
{
public:
    void Load();
    // ----
    void InitPlayMusic();

    static void PlayMusic();
};


extern cMaps gMaps;


#endif

NOTE 1: A small and interested thing about this code is this:

MOV EDX,DWORD PTR DS:[0x7A723B8] [COLOR=#800080]// -> Struct Preview WOW![/COLOR]
MOV AL,BYTE PTR DS:[EDX+0x0E] [COLOR=#800080]// -> EDX+0x0E or: #define pIsSafeZone(x) *(BYTE*)(x + 14)[/COLOR]
TEST AL,AL [COLOR=#800080]// -> Here make the comparation... I mean compare pSafeZone with char current pos[/COLOR] 
JE Label_1A [COLOR=#800080]// -> Then if character exists on a: "SafeZone" from this Map, Play Again the Music[/COLOR]

Then using your Imagination and with some knowledge... you can try to make something new and cool using: your MUSIC folder from your MU Client I don't know.. maybe something like this:

MOV EDX,DWORD PTR DS:[0x7A723B8] [COLOR=#800080]// -> Struct Preview[/COLOR]
MOV AL,BYTE PTR DS:[EDX+0x20] [COLOR=#800080]// -> EDX+0x20 or: #define pIsPK(x) *(BYTE*)(x + 32)[/COLOR]
TEST AL,AL [COLOR=#800080]// -> Here make the comparation... I mean compare pIsPK with your Character State[/COLOR] 
JE Label_1A [COLOR=#800080]// -> Here you can make a extra JUMP to Play ANOTHER: .mp3 Music file...[/COLOR] :wink:

NOTE 2: You only must remember put different names to every: "Label" that you add to this code for every new Map Case. Ex: Label_1E, Label_1F, etc.
