void CUser::AddApplySkillBuff(CUser* user, SkillInfo* skillInfo)
{
   typedef void(__stdcall* LPFN)(CUser*, SkillInfo*);
   (*(LPFN)0x494140)(user, skillInfo);
}

 

I tried using this to add skill buff to a player, it just triggered the animation of using the buff and it didn't add the buff icon.

 

auto charName = args.at(0);  // character name
auto skillId = std::stoi(args.at(1));
auto skillLevel = std::stoi(args.at(2));

auto user = CWorld::FindUser(charName.c_str());
if (!user) {
   std::stringstream output_format;
   output_format << "Character " << charName << " not found";
   output = output_format.str();
   return 0; // Exit if user is not found
}

auto skill = CGameData::GetSkillInfo(skillId, skillLevel);
if (!skill) {
   std::stringstream output_format;
   output_format << "Skill with ID " << skillId << " and level " << skillLevel << " not found";
   output = output_format.str();
   return 0; // Exit if skill is not found
}

// Apply the skill buff
CUser::AddApplySkillBuff(user, skill);

// Prepare the SkillUseOutgoing2 packet
SkillApplyOutgoing outgoing{};
outgoing.id = user->applySkills.last->id;
outgoing.skillId = skill->skillId;
outgoing.skillLv = skill->skillLv;

//Send the skill usage packet to the user
Helpers::Send(user, &outgoing, sizeof(SkillApplyOutgoing));

// Output a success message
std::stringstream output_format;
output_format << "Skill " << skillId << " (Level " << skillLevel << ") triggered for " << charName;
output = output_format.str();
return 0;

[mention=38]Zhein[/mention]

 

How about this?

 

// Prepare the SkillUseOutgoing packet
SkillUseOutgoing outgoing{};
outgoing.senderId = user->connection.object.id;
outgoing.targetId = user->connection.object.id;
outgoing.skillId = skill->skillId;
outgoing.skillLv = skill->skillLv;

// Send the skill usage packet to the user
Helpers::Send(user, &outgoing, sizeof(SkillUseOutgoing));

// Apply the skill buff
CUser::AddApplySkillBuff(user, skill);

Do you have the CT of ep5.4 plus the equipment bar?

EP5.4 How to increase the equipment slot

u mean 3 skill bar?

CUser::AddApplySkillBuff(user, skill);

 

Will this sends Packet 0x50D on its own or do I have to do it by myself?

 

I tried this

 

auto charName = args.at(0);  // character name
   auto skillId = std::stoi(args.at(1));
   auto skillLevel = std::stoi(args.at(2));

   auto user = CWorld::FindUser(charName.c_str());
   if (!user) {
       std::stringstream output_format;
       output_format << "Character " << charName << " not found";
       output = output_format.str();
       return 0; // Exit if user is not found
   }

   auto skill = CGameData::GetSkillInfo(skillId, skillLevel);
   if (!skill) {
       std::stringstream output_format;
       output_format << "Skill with ID " << skillId << " and level " << skillLevel << " not found";
       output = output_format.str();
       return 0; // Exit if skill is not found
   }

   // Prepare the SkillUseOutgoing packet
   SkillUseOutgoing outgoing{};
   outgoing.senderId = user->connection.object.id;
   outgoing.targetId = user->connection.object.id;
   outgoing.skillId = skill->skillId;
   outgoing.skillLv = skill->skillLv;

   // Send the skill usage packet to the user
   Helpers::Send(user, &outgoing, sizeof(SkillUseOutgoing));

   // Apply the skill buff
   CUser::AddApplySkillBuff(user, skill);

   EnterCriticalSection(&user->applySkills.cs);

   // Start from the first node after the sentinel tail
   auto node = user->applySkills.sentinel.tail;
   node = node->next;  // Move to the first node
   user->applySkills.sentinel.head = node;

   int index = 0; // Index to track the skill position in the list
   bool skillFound = false;

   while (node && node != user->applySkills.sentinel.tail)
   {
       auto skillIn = reinterpret_cast<CSkill*>(node);

       // Check if the skill matches
       if (skillIn->skillId == skill->skillId && skillIn->skillLv == skill->skillLv)
       {
           skillFound = true;

           // Correctly set the id for addBuff
           SkillApplyOutgoing addBuff{};
           addBuff.id = index; // Send the matching skill's index
           addBuff.skillId = skill->skillId;
           addBuff.skillLv = skill->skillLv;

           Helpers::Send(user, &addBuff, sizeof(SkillApplyOutgoing));
           break;
       }

       node = node->next;  // Move to the next node
       user->applySkills.sentinel.head = node;
       index++; // Increment index
   }

   LeaveCriticalSection(&user->applySkills.cs);

   if (!skillFound)
   {
       std::stringstream output_format;
       output_format << "Skill " << skillId << " (Level " << skillLevel << ") could not be applied for " << charName;
       output = output_format.str();
       return 0; // Exit after reporting error
   }

   // Output a success message
   std::stringstream output_format;
   output_format << "Skill " << skillId << " (Level " << skillLevel << ") triggered for " << charName;
   output = output_format.str();
   return 0;

 

Upon testing, it says Example

 

Skill 287 (Level 1) could not be applied for Character

Will this sends Packet 0x50D on its own or do I have to do it by myself?

I don't see it sending that packet.

 

I think you should use "nostrum" skills and do it this way:

 

auto charName = args.at(0);  // character name
auto skillId = std::stoi(args.at(1));
auto skillLevel = std::stoi(args.at(2));

auto user = CWorld::FindUser(charName.c_str());
if (!user) {
   std::stringstream output_format;
   output_format << "Character " << charName << " not found";
   output = output_format.str();
   return 0; // Exit if user is not found
}

auto skill = CGameData::GetSkillInfo(skillId, skillLevel);
if (!skill) {
   std::stringstream output_format;
   output_format << "Skill with ID " << skillId << " and level " << skillLevel << " not found";
   output = output_format.str();
   return 0; // Exit if skill is not found
}

if (!CUser::UseItemSkill(user, skill)) {
   std::stringstream output_format;
   output_format << "Skill " << skillId << " (Level " << skillLevel << ") could not be applied for " << charName;
   output = output_format.str();
   return 0; // Exit after reporting error
}

// Output a success message
std::stringstream output_format;
output_format << "Skill " << skillId << " (Level " << skillLevel << ") triggered for " << charName;
output = output_format.str();
return 0;

 

I had to update the return type of UseItemSkill, so please change it from void to bool in your code.

I want to modify the code of this in the server side. Anyone knows the address to get started (in Essentail files)

[mention=38]Zhein[/mention]

 

If you want to overwrite the case and write your own handler, you could set a detour at 0x47A010, with 8 bytes as the length and jmp to 0x47A018 at the end of the assembly function. The user is in edi and the packet is in esi.

Can I ask why the item gems, craftname and quality is not persistent?

You have to send a packet to the dbAgent service. Looks like the remake function sends 0x701. I added it to the library.

 

Please add range checks for the bags and slots. :p

 

Edit: sending 0x711 and 0x717 to the dbAgent service resolved the issue.

@[mention=7]Bowie[/mention] hi i find the Item Ability Transfer have Bug in attribute overlay. The attributes of the equipment worn on the body are transferred to the new equipment, and then the new equipment is put on. It will add the attribute of additional gems embedded in the equipment.

Repeating this operation can infinitely increase the attributes of the character.

this bug Bowie fix into v1.6.5

Any idea on how to handle different item type/typeids for each of the 3 slots ? For example, when I put 3 same items my packet handler is executed but if I put 3 different items nothing happens.
