new command #advnpcspawn and related functions

first, appending ZoneDatabase::NPCSpawnDB(int8 command, const char* zone, Client *c, NPC* spawn, int32 extra)
two additional cases for the main switch

Code:

                case 5: { // add a spawn from spawngroup - Ailia

                        char tmpstr[64];

                        //char tmpstr2[64];

                        if (!RunQuery(query, MakeAnyLenString(&query, "INSERT INTO spawn2 (zone, x, y, z, respawntime, heading, spawngroupID) values('%s', %f, %f, %f, %i, %f, %i)", zone, c->GetX(), c->GetY(), c->GetZ(), 120, c->GetHeading(), extra), errbuf, 0, 0, &tmp)) {

                                safe_delete(query);

                                return false;

                        }

                        if(c) c->LogSQL(query);

                        safe_delete_array(query);



                        return true;

                        break;

                        }

                case 6: { // add npc_type - Ailia

                        int32 npc_type_id, spawngroupid;

                        char tmpstr[64];

                        //char tmpstr2[64];

                        EntityList::RemoveNumbers(strn0cpy(tmpstr, spawn->GetName(), sizeof(tmpstr)));

                        if (!RunQuery(query, MakeAnyLenString(&query, "INSERT INTO npc_types (name, level, race, class, hp, gender, texture, helmtexture, size, loottable_id, merchant_id, face, runspeed) values(\"%s\",%i,%i,%i,%i,%i,%i,%i,%f,%i,%i,%i,%f)", tmpstr, spawn->GetLevel(), spawn->GetRace(), spawn->GetClass(), spawn->GetMaxHP(), spawn->GetGender(), spawn->GetTexture(), spawn->GetHelmTexture(), spawn->GetSize(), spawn->GetLoottableID(), spawn->MerchantType, 0, spawn->GetRunspeed()), errbuf, 0, 0, &npc_type_id)) {

                                safe_delete(query);

                                return false;

                        }

                        if(c) c->LogSQL(query);

                        safe_delete_array(query);

                        c->Message(0, "%s npc_type ID %i created successfully!", tmpstr, npc_type_id);

                        return true;

                        break;

                }

line 139-143 or so,spawn2.cpp
adding a catch to load missing spawngroups to allow worldbuilding without rebooting zone

Code:

                //grab our spawn group

                SpawnGroup* sg = zone->spawn_group_list.GetSpawnGroup(spawngroup_id_);

                if (sg == NULL) {

                        database.LoadSpawnGroupsByID(spawngroup_id_,&zone->spawn_group_list);

                        sg = zone->spawn_group_list.GetSpawnGroup(spawngroup_id_);

                }



                if (sg == NULL) {

                        _log(SPAWNS__MAIN, "Spawn2 %d: Unable to locate spawn group %d. Disabling.", spawn2_id, spawngroup_id_);

                        return false;

                }

LoadSpawnGroupsByID function from previous code block added to spawngroup.cpp

Code:

bool ZoneDatabase::LoadSpawnGroupsByID(int spawngroupid, SpawnGroupList* spawn_group_list) {

        char errbuf[MYSQL_ERRMSG_SIZE];

        char *query = 0;

        MYSQL_RES *result;

        MYSQL_ROW row;

        



        // CODER new spawn code

        query = 0;

        if (RunQuery(query, MakeAnyLenString(&query, "SELECT DISTINCT spawngroup.id, spawngroup.name, spawngroup.spawn_limit, spawngroup.dist, spawngroup.max_x, spawngroup.min_x, spawngroup.max_y, spawngroup.min_y, spawngroup.delay FROM spawngroup WHERE spawngroup.ID='%i'", spawngroupid), errbuf, &result))

        {

                safe_delete_array(query);

                while((row = mysql_fetch_row(result))) {

                        spawn_group_list->AddSpawnGroup(newSpawnGroup);

                }

                mysql_free_result(result);

        }

        else

        {

                cerr << "Error2 in PopulateZoneLists query '" << query << "' " << errbuf << endl;

                safe_delete_array(query);

                return false;

        }



        query = 0;

                safe_delete_array(query);

                while((row = mysql_fetch_row(result)))

                {

                        SpawnEntry* newSpawnEntry = new SpawnEntry( atoi(row[1]), atoi(row[2]), row[3]?atoi(row[3]):0);

                        SpawnGroup *sg = spawn_group_list->GetSpawnGroup(atoi(row[0]));

                }

                mysql_free_result(result);

        }

        else

                cerr << "Error3 in PopulateZoneLists query '" << query << "' " << errbuf << endl;

                safe_delete_array(query);

                return false;

        }



        // CODER end new spawn code

        return true;

}

loading random roaming data in spawn2.cpp following entity_list.LimitAddNPC(npc);

Code:

                if(sg->roamdist && sg->roambox[0] && sg->roambox[1] && sg->roambox[2] && sg->roambox[3] && sg->delay)

                npc->AI_SetRoambox(sg->roamdist,sg->roambox[0],sg->roambox[1],sg->roambox[2],sg->roambox[3],sg->delay);

2ndary constructor for spawngroup to hold group roaming data

Code:

SpawnGroup::SpawnGroup( uint32 in_id, char* name, int in_group_spawn_limit, float dist, float maxx, float minx, float maxy, float miny, int delay_in ) {

        id = in_id;

        strncpy( name_, name, 120);

        group_spawn_limit = in_group_spawn_limit;

        roambox[0]=maxx;

        roambox[1]=minx;

        roambox[2]=maxy;

        roambox[3]=miny;

        roamdist=dist;

        delay=delay_in;

}

updated loadspawngroups function with slightly faster queries and support for roaming data

Code:

bool ZoneDatabase::LoadSpawnGroups(const char* zone_name, SpawnGroupList* spawn_group_list) {

        char errbuf[MYSQL_ERRMSG_SIZE];

                        spawn_group_list->AddSpawnGroup(newSpawnGroup);

                }

                mysql_free_result(result);

        else

Hope thats everything, probably forgot some header changes but those should be easy enough to fix.

Code currently being used on the server EDGE as our primary worldbuilding tool due to not creating redundant spawngroups and spawnentries allowing much faster queries and less redundancy in the database.

before i forget, you need to add the following to the spawngroup table
dist, max_x, min_x, max_y, min_y, delay
delay is an integer, rest are floats
default all to 0

Cripp edit:: Here is the SQL syntax for adding the fields..

Code:

ALTER TABLE `spawngroup` ADD `dist` FLOAT NOT NULL DEFAULT '0.0',

ADD `max_x` FLOAT NOT NULL DEFAULT '0.0',

ADD `min_x` FLOAT NOT NULL DEFAULT '0.0',

ADD `max_y` FLOAT NOT NULL DEFAULT '0.0',

ADD `min_y` FLOAT NOT NULL DEFAULT '0.0',

ADD `delay` INT NOT NULL DEFAULT '0';

Find -- if (!CalculateNewPosition2(roambox_movingto_x, roambox_movingto_y, GetZ(), walksp, true))

Code:

                {

                        roambox_movingto_x = roambox_max_x + 1; // force update

                        pLastFightingDelayMoving = Timer::GetCurrentTime() + RandomTimer(roambox_delay, roambox_delay + 5000);

                        SetMoving(false);

                        SendPosition();        // makes mobs stop clientside

                }

I'll get to this and hopefully the remaining submissions I haven't gotten to within the next couple days I hope I hope.

added a addspawn2 option for #advnpcspawn.. so you can manually add spawn2 entrys.

edit:: apparently "theres no point" in my spawn2 entry addition.. thanks ailia

did this ever make into source? if not could it be put on the list again? =) thanks in advance KLS keep up the good work.

It did not. It's a shame, good code, I use it still.

Especially roamboxes, they work wonders if you know how to use them.

Can replace grids in open areas.

This is why I say, if it looks good, put it in and let everyone try and decide ASAP. You can always take it out again.
This guy got his code ignored, when he probably would have been a great help to the project. Now hes gone :(

could someone elaborate WHAt does advnpcspawn actual does?
and how to use it?

Code:

Format: #advnpdspawn makegroup <name> [spawn limit] [dist] [max x] [min x] [max y] [min y] [delay]

I think instead of doing an add on the NPC to add it to the zone, you make a spawngroup with this command that will also add in roam boxes as well as add more NPCs to an existing spawngroup (I think).

hmm so you teling me if i want to make a randomly roaming npc, this thing will essentialy substitute the need of making a grid for random area roamers?

wouldn't this require a whole new table in DB? and it should also store a zone id somewhere no?

The spawngroup is loaded on a repop or zone bootup with this code, and because of this, the zone ID is stored in spawn2 rather than spawngroup.

Also, roamboxes are stored in spawngroup so a random NPC can spawn each time.

If no roambox is specified, the NPC finds a grid. If no grid is specifed, the NPC stays static and does nothing. Pretty easy system.

This code is in the SVN for anybody who wishes to fiddle with it. It worked pretty well in my limited testing.

wondering....need to remove a spawn group. client side how do i do that with this set of cmd's?

didnt see an argument to remove a spawngroup id so need to know how to do this remotely from the server
