[Tutorial] Criando um NPC

Vendo que há um grande número de postos de trabalho na linha de Twilight Suzuka Como: Faça um NPC perfeito . . Decidi tentar e fazer o meu próprio NPC usando esse tutorial, mas acrescentou recursos extras
Algumas delas são:
Bata animações
Animações de morte
Animações ociosas
Sangrar / desencadear efeitos
Voz NPC falando
E muito mais!

Antes de iniciar este tutorial vamos explicar melhor o que é exatamente um NPC e por que devemos fazer antes de um how. NPC significa caráter não-jogável. Como o nome sugere, é simplesmente uma entidade que não é jogável. . Nós, como programadores têm total controle sobre a forma como eles interagem e trabalham Alguns exemplos do que um NPC pode fazer são:

Espectadores que anima. (Muito legal para fazer para o futebol Jam)
Um proprietário de loja de itens
Props para o seu mod. (Fazendo lâmpada / luz mensagens que poderiam flicker)
Tudo o que você pode pensar!

Tudo bem! Permite, finalmente, começar a fazer o nosso próprio NPC! Começamos incluindo as bibliotecas necessárias para tornar o nosso NPC

Código PHP:

Código:

# Include < amxmodx > 
# include < amxmisc >
# include < fakemeta > 
# include < engine > 
# include < hamsandwich >

Um grupo de variáveis globais que nosso NPC irá usar.

Código PHP:

Código:

//Boolean of when NPC spawned  
new bool: g_NpcSpawn[256];  
//Boolean to check if NPC is alive or not  
new bool: g_NpcDead[256];  
//Classname for our NPC  
new const g_NpcClassName[] = "ent_npc";  
//Constant model for NPC  
new const g_NpcModel[] = "models/barney.mdl";  

//List of sounds our NPC will emit when damaged  
new const g_NpcSoundPain[][] =   
{  
    "barney/ba_pain1.wav",  
    "barney/ba_pain2.wav",  
    "barney/ba_pain3.wav"  
}  

//Sounds when killed  
new const g_NpcSoundDeath[][] =  
{  
    "barney/ba_die1.wav",  
    "barney/ba_die2.wav",  
    "barney/ba_die3.wav"  
}  

//Sounds when we knife our flesh NPC 
new const g_NpcSoundKnifeHit[][] =  
{ 
    "weapons/knife_hit1.wav", 
    "weapons/knife_hit2.wav", 
    "weapons/knife_hit3.wav", 
    "weapons/knife_hit4.wav" 
} 

new const g_NpcSoundKnifeStab[] = "weapons/knife_stab.wav"; 

//List of idle animations  
new const NPC_IdleAnimations[] = { 0, 1, 2, 3, 11, 12, 18, 21, 39, 63, 65 }; 

//Sprites for blood when our NPC is damaged 
new spr_blood_drop, spr_blood_spray 

//Player cooldown for using our NPC  
new Float: g_Cooldown[32]; 

//Boolean to check if we knifed our NPC 
new bool: g_Hit[32];

Agora temos que precache nosso modelo e os sons ou o jogo vai cair! E também um comando para gerar o nosso NPC.

Nesta seção, temos de iniciar algumas encaminha para o nosso NPC. Trata-se de onde os recursos extras são chamados de.

Este também é o lugar onde nós podemos carregar nossas configurações salvas.

PHP Code:

Código:

public plugin_init() 
{ 
    register_plugin("NPC Plugin", "1.1", "Mazza"); 
    register_clcmd("say /npc", "ClCmd_NPC"); 
     
    register_event("HLTV", "Event_NewRound", "a", "1=0", "2=0"); 
         
    RegisterHam(Ham_TakeDamage, "info_target", "npc_TakeDamage"); 
    RegisterHam(Ham_Killed, "info_target", "npc_Killed"); 
    RegisterHam(Ham_Think, "info_target", "npc_Think"); 
    RegisterHam(Ham_TraceAttack, "info_target", "npc_TraceAttack"); 
    RegisterHam(Ham_ObjectCaps, "player", "npc_ObjectCaps", 1 ); 
     
    register_forward(FM_EmitSound, "npc_EmitSound");  
} 

public plugin_precache() 
{ 
    spr_blood_drop = precache_model("sprites/blood.spr") 
    spr_blood_spray = precache_model("sprites/bloodspray.spr") 
     
    new i; 
    for(i = 0 ; i < sizeof g_NpcSoundPain ; i++) 
        precache_sound(g_NpcSoundPain[i]); 
    for(i = 0 ; i < sizeof g_NpcSoundDeath ; i++) 
        precache_sound(g_NpcSoundDeath[i]); 

    precache_model(g_NpcModel) 
} 

public plugin_cfg() 
{ 
    Load_Npc() 
}

Quando digitar "/ NPC" um menu será exibido com as opções do que fazer.
Nota: Eu estou usando o novo sistema de menu AMXX para exibir o menu, graças a EMP `

PHP Code:

Código:

public ClCmd_NPC(id) 
{ 
    //Create a new menu 
    new menu = menu_create("NPC: Main Menu", "Menu_Handler"); 
     
    //Add some items to the newly created menu 
    menu_additem(menu, "Create NPC", "1"); 
    menu_additem(menu, "Delete NPC", "2"); 
    menu_additem(menu, "Save current NPC locations", "3"); 
    menu_additem(menu, "Delete all NPC", "4"); 
     
    //Let the menu have an 'Exit' option 
    menu_setprop(menu, MPROP_EXIT, MEXIT_ALL); 
     
    //Display our menu 
    menu_display(id, menu); 
} 

public Menu_Handler(id, menu, item) 
{ 
    //If user chose to exit menu we will destroy our menu 
    if(item == MENU_EXIT) 
    { 
        menu_destroy(menu); 
        return PLUGIN_HANDLED; 
    } 
     
    new info[6], szName[64]; 
    new access, callback; 
     
    menu_item_getinfo(menu, item, access, info, charsmax(info), szName, charsmax(szName), callback); 
     
    new key = str_to_num(info); 
     
    switch(key) 
    { 
        case 1: 
        { 
            //Create our NPC 
            Create_Npc(id); 
        } 
        case 2: 
        { 
            //Remove our NPC by the users aim 
            new iEnt, body, szClassname[32]; 
            get_user_aiming(id, iEnt, body); 
             
            if (is_valid_ent(iEnt))  
            { 
                entity_get_string(iEnt, EV_SZ_classname, szClassname, charsmax(szClassname)); 
                 
                if (equal(szClassname, g_NpcClassName))  
                { 
                    remove_entity(iEnt); 
                } 
                 
            } 
        } 
        case 3: 
        { 
            //Save the current locations of all the NPCs 
            Save_Npc(); 
             
            client_print(id, print_chat, "[AMXX] NPC origin saved succesfully"); 
        } 
        case 4: 
        { 
            //Remove all NPCs from the map 
            remove_entity_name(g_NpcClassName); 
             
            client_print(id, print_chat, "[AMXX] ALL NPC origin removed"); 
        } 
    } 
     
    //Keep the menu displayed when we choose an option 
    menu_display(id, menu); 
     
    return PLUGIN_HANDLED; 
}

Adicionar alguns recursos extras para o nosso NPC.

Em caso de um novo ciclo. Vamos redefinir nossas propriedades NPC.

PHP Code:

Código:

public Event_NewRound() 
{ 
    new iEnt = -1; 
     
    //Scan and find all of the NPC classnames 
    while( ( iEnt = find_ent_by_class(iEnt, g_NpcClassName) ) ) 
    { 
        //If we find a NPC which is dead... 
        if(g_NpcDead[iEnt]) 
        { 
            //Reset the solid box 
            entity_set_int(iEnt, EV_INT_solid, SOLID_BBOX); 
            //Make our NPC able to take damage again 
            entity_set_float(iEnt, EV_FL_takedamage, 1.0); 
            //Make our NPC instanstly think 
            entity_set_float(iEnt, EV_FL_nextthink, get_gametime() + 0.01); 
             
            //Reset the NPC boolean to false 
            g_NpcDead[iEnt] = false; 
        }     
         
        //Reset the health of our NPC 
        entity_set_float(iEnt, EV_FL_health, 250.0); 
    } 
}

O método que realmente cria o nosso NPC.

PHP Code:

Código:

Create_Npc(id, Float:flOrigin[3]= { 0.0, 0.0, 0.0 }, Float:flAngle[3]= { 0.0, 0.0, 0.0 } ) 
{ 
    //Create an entity using type 'info_target'

    //If we are reading from a file 
    else  
    { 
        //Set the origin and angle based on the values of the parameters 
        entity_set_origin(iEnt, flOrigin); 
        entity_set_vector(iEnt, EV_VEC_angles, flAngle); 
    } 

    //Set our NPC to take damange and how much health it has 
    entity_set_float(iEnt, EV_FL_takedamage, 1.0); 
    entity_set_float(iEnt, EV_FL_health, 250.0); 

    //Set a model for our NPC 
    entity_set_model(iEnt, g_NpcModel); 
    //Set a movetype for our NPC 
    entity_set_int(iEnt, EV_INT_movetype, MOVETYPE_PUSHSTEP); 
    //Set a solid for our NPC 
    entity_set_int(iEnt, EV_INT_solid, SOLID_BBOX); 
     
     
    //Create a bounding box for oru NPC 
    new Float: mins[3] = {-12.0, -12.0, 0.0 } 
    new Float: maxs[3] = { 12.0, 12.0, 75.0 } 

    entity_set_size(iEnt, mins, maxs); 
     
    //Controllers for our NPC. First controller is head. Set it so it looks infront of itself 
    entity_set_byte(iEnt,EV_BYTE_controller1,125); 
    // entity_set_byte(ent,EV_BYTE_controller2,125); 
    // entity_set_byte(ent,EV_BYTE_controller3,125); 
    // entity_set_byte(ent,EV_BYTE_controller4,125); 
     
    //Drop our NPC to the floor 
    drop_to_floor(iEnt); 
     
    // set_rendering( ent, kRenderFxDistort, 0, 0, 0, kRenderTransAdd, 127 ); 
     
    //We just spawned our NPC so it should not be dead 
    g_NpcSpawn[iEnt] = true; 
    g_NpcDead[iEnt] = false; 
     
    //Make it instantly think 
    entity_set_float(iEnt, EV_FL_nextthink, get_gametime() + 0.01)

Os métodos que carregar e salvar os locais do nosso NPC.

PHP Code:

Código:

Save_Npc() 
{ 
    //Variables 
    new szConfigsDir[256], szFile[256], szNpcDir[256]; 
     
    //Get the configs directory. 
    get_configsdir(szConfigsDir, charsmax(szConfigsDir)); 
     
    //Get the current map name 
    new szMapName[32]; 
    get_mapname(szMapName, charsmax(szMapName)); 
     
    //Format 'szNpcDir' to ../configs/NPC 
    formatex(szNpcDir, charsmax(szNpcDir),"%s/NPC", szConfigsDir); 
    //Format 'szFile to ../configs/NPC/mapname.cfg 
    formatex(szFile, charsmax(szFile), "%s/%s.cfg", szNpcDir, szMapName); 
         
    //If there is already a .cfg for the current map. Delete it 
    if(file_exists(szFile)) 
        delete_file(szFile); 
     
    //Variables 
    new iEnt = -1, Float:fEntOrigin[3], Float:fEntAngles[3]; 
    new sBuffer[256]; 
     
    //Scan and find all of my custom ents 
    while( ( iEnt = find_ent_by_class(iEnt, g_NpcClassName) ) ) 
    { 
        //Get the entities' origin and angle 
        entity_get_vector(iEnt, EV_VEC_origin, fEntOrigin); 
        entity_get_vector(iEnt, EV_VEC_angles, fEntAngles); 
         
        //Format the line of one custom ent. 
        formatex(sBuffer, charsmax(sBuffer), "%d %d %d | %d", floatround(fEntOrigin[0]), floatround(fEntOrigin[1]), floatround(fEntOrigin[2]), floatround(fEntAngles[1])); 
         
        //Finally write to the mapname.cfg file and move on to the next line 
        write_file(szFile, sBuffer, -1); 
         
        //We are currentlying looping to find all custom ents on the map. If found another ent. Do the above till there is none. 
    } 
     
}

Diversos método para a criação de animações para o nosso NPC.

PHP Code:

Código:

stock Util_PlayAnimation(index, sequence, Float: framerate = 1.0) 
{ 
    entity_set_float(index, EV_FL_animtime, get_gametime()); 
    entity_set_float(index, EV_FL_framerate,  framerate); 
    entity_set_float(index, EV_FL_frame, 0.0); 
    entity_set_int(index, EV_INT_sequence, sequence); 
}
