Good guide 

[kelviow2]

not working

[katia666]

Hi! good guide, but.. i have a question.

 

how to add this? 

 

in first part i create the NpcSpeedLoad.h and copy the content...

 

in 2th part i create the NpcSpeedLoad.h and .cpp and copy the content... but.

 

i have a quiestion about: 

"invoke CNpcSpeedLoad::Initialize() in dllmain"

 

i added CNpcSpeedLoad::Initialize() 
in a dllmain.h (in IlExt)

 

but the second part say same invoke CNpcSpeedLoad::Initialize() in dllmain but... in a NPCExt doesn't have a dllmain.h

On Npc.cpp add

 

#include "NpcSpeedLoad.h" 

and CNpcSpeedLoad::Initialize(); under

 

        CSharedFactory::Init();
        CNPC::ExtInit();
        CNPCEventFactory::Init();
        CPostLoad::Init();
        CBaseAction::Init();
        CTimer::Init();
        CScriptAccessible::Init();
