it's pretty much it... go check the Merv functions of get_tag and set_tag, might help you understanding.

When you get_tag, the code scrolls through all the tags you've set, and when the player AND the index matches, it returns you the current value of that tag (the data). If it doesn't find any tag for that player with that index, it returns 0 by default.

a player* is like a book
an index is like the page number
data is the contents of the page,

so set_tag(p,455,70) writes the value "70" on page 455 of player p's book.

to get the value on page 455 do

Code: Show/Hide int value = get_tag(p,455);

Don't confuse #define with a standard definition like int i = 0. In the snippet I posted, #define INDEX 2 is saying that INDEX has 3 values; or using Bak's analogy, 3 pages. It is not the same as int INDEX = 3.

[Bak]

wat? are you sure purge?

[Samapico]

uh... no... #define INDEX 2 means that anywhere you put INDEX in your code, it is replaced by "2" before anything is even compiled.

For example, if I need 3 tags, I usually do something like:
#define TAG_SOMETAG 0
#define TAG_ANOTHERTAG 1
#define TAG_THIRDTAG 2

And I use these as index values.

And what purge said isn't true... last I checked, the tags is a linkedlist, not an array. Each tag on the linked list is a struct with Player* p, int index and int data.

[Bak]

to drive the point home, you can compile

Code: Show/Hide #define APPLE int main() #define SAUCE return 0; APPLE { SAUCE }

[Samapico]

in Mervbot, you can use

WHEN_COWS_FLY
{
//statements
}

for something that will never happen...
If I remember right, there is:
#define WHEN_COWS_FLY if(false)
somewhere in the code

Meh, sorry about the bad info. This is why I'm premed and not computer anything.

Ok i get the tags now and made a bot with them that works just how do you do a code that if any point during game that event happens, then exectute other code

this is the code when i tried to make the bot and it works just the bot realizes you beat the mission only you type something to him

also here the mission is to collect 30 bounty

Code: Show/Hide          // EASY MISSION BOUNTY HUNTER CODE          else if (c->check("easymission:1"))  // start easy bounty hunter mission          {             if (get_tag(p,mission1)!=on)             {                sendPrivate(p,"You started an easy mission \"Bounty Hunter\" Type !abort:easy:1 anytime during the game to abort this mission");                set_tag(p, mission1, on);             }             else if (get_tag(p,mission1)==on)             {                sendPrivate(p,"You already started easy mission \"Bounty Hunter\" Type !abort:easy:1 to abort mission.");             }          }          else if ( get_tag(p,mission1)==on && p->bounty>=30 )          {             sendPrivate(p,"You beated easy mission \"Bounty Hunter\" Congratulations!");             sendPrivate(p,"*points 5000");             set_tag(p,mission1,off);          }          else if (c->check("abort:easy:1"))          {             if (get_tag(p,mission1)==on)             {                sendPrivate(p,"You aborted easy mission \"Bounty Hunter\"");                set_tag(p,mission1,off);             }             else if (get_tag(p,mission1)!=on)             {                sendPrivate(p,"You never started easy mission \"Bounty Hunter\"");             }          }          // END OF EASY MISSION BOUNTY HUNTER CODE

also i got this in spawn.h

Code: Show/Hide #define mission1 1 #define on 1  // mission is on #define off 0 // mission is off

also to samapico:
yup ur right its in datatypes.h

[Purge]

The bot only realizes the player won when he types in the command since that is the only place you are checking for a win. So you must check for a win in a player event in spawn.cpp like Player_Prize (I think).

[Samapico]

Quick suggestion for cleaner code:

Code: Show/Hide if (get_tag(p,mission1)!=on) { sendPrivate(p,"You started an easy mission \"Bounty Hunter\" Type !abort:easy:1 anytime during the game to abort this mission"); set_tag(p, mission1, on); } else if (get_tag(p,mission1)==on) sendPrivate(p,"You already started easy mission \"Bounty Hunter\" Type !abort:easy:1 to abort mission."); }

You defined the 'off' value, you might as well use it... and since you're doing the "else" part, you only need to get_tag once, since the tag only has 2 possible values.

Code: Show/Hide if (get_tag(p,mission1)==off) { sendPrivate(p,"You started an easy mission \"Bounty Hunter\" Type !abort:easy:1 anytime during the game to abort this mission"); set_tag(p, mission1, on); } else { sendPrivate(p,"You already started easy mission \"Bounty Hunter\" Type !abort:easy:1 to abort mission."); }

And to fix your problem, you must do as Purge said. Typically, most of your plugin code should be in spawn.cpp, in the various events. The commands.cpp should only include stuff that are directly triggered by !commands, like turn on/off something, like you're doing with your mission. However, once the command is done, you have to rely on events to know what's going on.
You can also use global variables in spawn.cpp and command.cpp if you declare them in spawn.h, in the botInfo class declaration.

[hellzlaker]

ok thanks

[hellzlaker]

Also I am going to create a tag that deals with current time, and where would exactly i would put in spawn.ccp? ( i was guessing like playermove =\)

this is just kind of how it will look like

Code: Show/Hide #include <ctime> // header

Code: Show/Hide if (get_tag(p,0)==1) { time_t breaktime=time(0); int freezetime = (int) breaktime; if (breaktime==freezetime+300) { set_tag(p,0,0); } }

[Bak]

EVENT_TICK happens once a second. you can set like the time to 300 when they start and every EVENT_TICK have a countdown.

Code: Show/Hide // inside EVENT_TICK // go through every player in the arena for (_listnode <Player> *parse = playerlist->head; parse; parse = parse->next) {   Player* p = parse->item;   int playing = get_tag(p,TAG_INDEX_PLAYING);   if (playing == ON)   {     int remaining = get_tag(p,TAG_INDEX_TIME);     if (remaining <= 0)       // you lose       set_tag(p,TAG_INDEX_PLAYING,OFF);     else       set_tag(p,TAG_INDEX_TIME, remaining - 1); }

[hellzlaker]

what do you mean by go through every person in arena ?

and i dont get that for()

Code: Show/Hide // go through every player in the arena for (_listnode <Player> *parse = playerlist->head; parse; parse = parse->next)

EDIT: also can you have more then 1 EVENT_TICK?

[Samapico]

check how the get_tag function is done, it uses the same thing (except it's a while loop instead of a for loop).
Basically, "playerlist" is a linked list...

A linked list is made of "nodes"
Each node contains 3 important information:

A pointer to the previous node of the list
A pointer to the next node of the list (parse->next)
A pointer to the actual data (parse->item)

For example, in playerlist, the items are 'Player' structs.

So what that loop does, is initialize a pointer to the start of the list (playerlist->head). Once you've done what you wanted with that item, you advance to the next (parse = parse->next)
The stop condition of the loop is 'parse', which means as long as the pointer is not NULL, it will keep going. The last item of the list doesn't have any 'next' item, so at that point you will get the NULL value.

[Samapico]

As for you EVENT_TICK question... there is only one EVENT_TICK event, however, you can have more than one countdowns going at once. By default, there are 4 countdowns set. Look in spawn.h you will find the initialization of them; looks like 'int countdown[4];' or something. You can put as many countdowns as you wish. You just have to adjust the code in the EVENT_TICK part.

[Bak]

why would you want more than one EVENT_TICK ?

I'd try to explain the for loop but samapico is pretty much right. It involves pointers and structures and templates, which aren't hard on their own but if you're trying to learn all of them at once it can be overwhelming. Suffice it to say there's a list of every Player* in the arena called playerlist, and that's how you go through it.

[hellzlaker]

wtf this doesnt compile right!

Code: Show/Hide       {          for (int i = 0; i < 4; ++i)             --countdown[i];          if (get_tag(p,breaktime)!=0)          {             int remainingtime = get_tag(p,breaktime);             set_tag(p,breaktime,remainingtime-1);          }       }

and get those errors

when i delete that code compiles just fine :\

[Purge]

You have to cycle through the playerlist so that it can search for a player to check tags.

Code: Show/Hide _listnode <Player> *parse = playerlist->head; while (parse) {       Player *p = parse->item;       if (get_tag(p,breaktime)!=0)             {                   int remainingtime = get_tag(p,breaktime);                   set_tag(p,breaktime,remainingtime-1);              }        parse = parse->next; }

That code should work. Also, you may want to fix those warnings regarding deprecated strings. Try declaring #define CRT_SECURE_NO_DEPRECATE in spawn.h.

[Samapico]

yeah... there is no 'p' in the EVENT_TICK part of the code. (C2065: 'p' : undeclared identifier)

[hellzlaker]

i declared that and still got same 3 errors also where could i find how to keep track of player kills? like bounty i know is p->bounty and there is EVENT player prize.. but is there a kill event?

[Samapico]

there is a death event... where there's a death, there's a kill.


And you can't just declare 'p' in EVENT_TICK... well you can, but it will be useless, you have to do what purge said, which is cycle through ALL the players every tick.

[hellzlaker]

Code: Show/Hide    case EVENT_PlayerDeath:       {          Player *p = (Player*)event.p[0],                *k = (Player*)event.p[1];          Uint16 bounty = (Uint16)(Uint32)event.p[2];          Uint16 flags = (Uint16)event.p[3];       }

kinda confusing and i assume *k is the killer, so if i would try something like keep track if a player killed 3 people without dying (like a spree) what would i do?
