Basic Feign Death code

[Wiz]

After around eight hours of struggling with this, it's complete. It's very crude right now, has no "remember" factor and will only work if you're top on aggro.

Next version should have both of these fixed. :)

Insert into client_process.cpp:

Where the code for standing up is:

if (sa->parameter == 0x64)
{
// cout << "Client " << name << " standing" << endl;
appearance = 0;
this->SetFeigned(0);
}


Among skills code:

case OP_FeignDeath:
{
int feignchance = GetSkill(FEIGN_DEATH);
int primfeign = GetSkill(FEIGN_DEATH);
if (primfeign > 100) {
primfeign = 100;
}
int secfeign = GetSkill(FEIGN_DEATH);
if (secfeign < 101) {
secfeign = 0;
}
else {
secfeign = secfeign - 100;
secfeign = secfeign / 2;
}
int totalfeign = primfeign + secfeign;
if (rand()%160 > (totalfeign)) {
Message(0,"You have fallen to the ground");
this->SetFeigned(0);
appearance = 3;
}
else {
this->SetFeigned(1);
appearance = 3;
}
if (rand()%210 > feignchance && rand()%3 == 1 && GetSkill(FEIGN_DEATH) < 200 && GetSkill(FEIGN_DEATH) < this->GetLevel()*5+5 ) {
this->SetSkill(25,++pp.skills[25]);
UpdateWho();
}
break;
}


Client.cpp

Insert to bottom of Client:Client (below isgrouped=false)

feigned = 0;


Insert to bottom of client.cpp

void Client::SetFeigned(int8 in_feigned) {
feigned=in_feigned;
}


client.h

Insert below bool GetPVP() { return pp.pvp; }

void SetFeigned(int8 in_feigned);
int8 GetFeigned() { return feigned; }


Insert at bottom of client.h, just above
};
#endif


int8 feigned;


npcAI.cpp

Replace if (!sender->IsEngaged()) with:


if (!sender->IsEngaged() && currentmob->CastToClient()>GetFeigned() != 1)


npc.cpp

And finally, just above if (target->GetID() != this->ownerid && attack_timer->Check()) (line 334) add:


if (hate_list.GetTop()->CastToClient()->GetFeigned() == 1) {
RemoveFromHateList(GetHateTop());
}


There it is :)

Version 2.0:

- Fixed a couple crash bugs
- Added basic spell breaks feign support
- Added basic memory code (NPC's can only remember one person right now, and if it returns to spawn point, memory list is wiped)

npc.cpp:

At the top of the script, just below extern SPDat_Spell_Struct spells[SPDAT_RECORDS]; add:


int feigntimer = 0;
int forgetchance = 0;


Remove the old hate_list code, add this one instead, right above return true; on line 505 (above summon code):


if (IsEngaged()) {
if (hate_list.GetTop()->CastToClient()->GetFeigned() == 1) {
char* the_id = hate_list.GetTop()->CastToClient()->GetName();
if (this->GetLevel() > 34) {
this->SetFeignMemory(the_id);
}
RemoveFromHateList(GetHateTop());
}
}


Then add this right below what you just added in:


if (this->GetFeignMemory() != "0") {
Client* remember_client = entity_list.GetClientByName(this->GetFeignMemory());
if (remember_client) {
if (remember_client->CastToClient()->GetFeigned()==0) {
AddToHateList(remember_client,1);
this->SetFeignMemory("0");
forgetchance = 0;
}
else if (feigntimer > 0) {
feigntimer = feigntimer - 1;
}
else if (rand()%100 <= forgetchance && feigntimer == 0) {
this->SetFeignMemory("0");
feigntimer = 100;
forgetchance = 0;
}
else if (feigntimer == 0) {
feigntimer = 100;
forgetchance = forgetchance + 4;
}
}
else {
this->SetFeignMemory("0");
}
}


Now, go into mob.cpp. In mob::mob right below invisible = false; add:


feign_memory = "0";


Add this to the very bottom of mob.cpp:


void Mob::SetFeignMemory(char* in_feign_memory) {
feign_memory=in_feign_memory;
}


Then go into mob.h. Right below int16 d_meele_texture2; add:


char* feign_memory;


Then in the main function array, for example under void CheckPet(); add:


void SetFeignMemory(char* in_feign_memory);
char* GetFeignMemory() { return feign_memory; }


Then, in spells.cpp, on whatever spell formulas you want to break feign:


if (this->CastToClient()->GetFeigned()==1) {
this->Message(0,"You are no longer feigning death because a spell hit you!");
this->CastToClient()->SetFeigned(0);
}


There. Current functions of my feign code:

- Skill gain, success and failure.
- All mobs will stop attacking you on success, if you are top of their aggro list.
- Mobs will not aggro a feigned person.
- Mobs above level 34, if they haven't returned to their spawn point, will remember one feigned person (last person who feigned). Every few seconds they have a chance to forget him. If he stands up while on memory list, they'll reaggro.
- Spells will interrupt feign.

[Wiz]

Also, a little todo list:

- Replace getting top aggro with cycling through aggro list.
- Support for larger memory lists.
- Spell FD with skill checks against abjure.

Edited version 2.0 post with a couple tweaks and a bug fix.

[Maniac]

when adding something like this, you complile this and all the other source files together as your zone program right? Bit new to this =)

[Wiz]

Right, Maniac.

[Maniac]

Ok i spent like 20 mins adding all the files
to a project to find it wouldn't compile.
Is there a certain compiler i need?

[Wiz]

What are you using? Virtual C++?

[Maniac]

Dev C++ , a free one i found a while back. Open to suggestions for a better one to use =)

[Wiz]

Well, what are the compilation problems? You should just have to open the zone.dsw and compile.

[Maniac]

The fact i don't seem to have zone.dsw could be a start =P

[Wiz]

Redownload the 0.3.1.1 source.

[Maniac]

just did but only contained server, world, and client .dsw ...sorry to take up so much space with posts hehe =)

[Wiz]

Well yeah, use server.dsw then, and compile the Zone... paste any errors here.
