Making Basic calculator commands. - TaLhA XIV - 05.09.2012

Hello,
Okay this is my 4th tutorial showing that how can you make a simple calculator commands.I know it sounds newbish but I made this for people who are new.Not tested so tell me if anything goes wrong.Or tell me if I have done something wrong.

Here is the full code with explanation:

pawn Код:

#include <a_samp>//you all know this.
#include <sscanf2>//including sscanf include in the script.
#if defined FILTERSCRIPT

#endif
new Answer;//the variable which would store the answer.
public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/plus", cmdtext, true, 10) == 0)
    {
        new str[128],N1,N2;//these are the variables that will store the text of the string,the first number entered and the second.
        if(sscanf(cmdtext, "ii", N1, N2)) return SendClientMessage(playerid, -1, "Usage: /plus (1st number) (2nd number)");//this will send the player an error message if he enters invalid information or in a wrong format.
        format(str, sizeof(str), "The answer to %i + %i is %i", N1, N2, Answer);//this will format the answer and all the calculations and store it in the variable str.
        SendClientMessage(playerid,-1,str);//now this will send the information stored in the variable str to the player.
        return 1;
    }
    else if (strcmp("/minus", cmdtext, true, 10) == 0)
    {
        new str[128],N1,N2;//these are the variables that will store the text of the string,the first number entered and the second.
        if(sscanf(cmdtext, "ii", N1, N2)) return SendClientMessage(playerid, -1, "Usage: /minus (1st number) (2nd number)");//this will send the player an error message if he enters invalid information or in a wrong format.
        format(str, sizeof(str), "The answer to %i - %i is %i", N1, N2, Answer);//this will format the answer and all the calculations and store it in the variable str.
        SendClientMessage(playerid,-1,str);//now this will send the information stored in the variable str to the player.
        return 1;
    }
    else if (strcmp("/multiplay", cmdtext, true, 10) == 0)
    {
        new str[128],N1,N2;//these are the variables that will store the text of the string,the first number entered and the second.
        if(sscanf(cmdtext, "ii", N1, N2)) return SendClientMessage(playerid, -1, "Usage: /multiplay (1st number) (2nd number)");//this will send the player an error message if he enters invalid information or in a wrong format.
        format(str, sizeof(str), "The answer to %i x %i is %i", N1, N2, Answer);//this will format the answer and all the calculations and store it in the variable str.
        SendClientMessage(playerid,-1,str);//now this will send the information stored in the variable str to the player.
        return 1;
    }
    return 0;
}

replies appreciated.

slow way, and it should be float's. kinda useless this thread.

Re: Making Basic calculator commands. - TaLhA XIV - 05.09.2012

I know this is a slow way and cause the newbies would not use zcmd and things the first day,And I said that this was for newbies not for pro's like you

,thanks for the reply.

Re: Making Basic calculator commands. - Sanady - 05.09.2012

I don't think this will work

Re: Making Basic calculator commands. - TaLhA XIV - 05.09.2012

I have not tested it,just giving people idea how to make it.Thanks for the feed back.

Please test it... Seriously, test it!

bugged one:

pawn Код:

#include <a_samp>//you all know this.
#include <sscanf2>//including sscanf include in the script.
#if defined FILTERSCRIPT

#endif
new Answer;//the variable which would store the answer.
public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/plus", cmdtext, true, 10) == 0)
    {
        new str[128],N1,N2;//these are the variables that will store the text of the string,the first number entered and the second.
        if(sscanf(cmdtext, "ii", N1, N2)) return SendClientMessage(playerid, -1, "Usage: /plus (1st number) (2nd number)");//this will send the player an error message if he enters invalid information or in a wrong format.
        format(str, sizeof(str), "The answer to %i + %i is %i", N1, N2, Answer);//this will format the answer and all the calculations and store it in the variable str.
        SendClientMessage(playerid,-1,str);//now this will send the information stored in the variable str to the player.
        return 1;
    }
    else if (strcmp("/minus", cmdtext, true, 10) == 0)
    {
        new str[128],N1,N2;//these are the variables that will store the text of the string,the first number entered and the second.
        if(sscanf(cmdtext, "ii", N1, N2)) return SendClientMessage(playerid, -1, "Usage: /minus (1st number) (2nd number)");//this will send the player an error message if he enters invalid information or in a wrong format.
        format(str, sizeof(str), "The answer to %i - %i is %i", N1, N2, Answer);//this will format the answer and all the calculations and store it in the variable str.
        SendClientMessage(playerid,-1,str);//now this will send the information stored in the variable str to the player.
        return 1;
    }
    else if (strcmp("/multiplay", cmdtext, true, 10) == 0)
    {
        new str[128],N1,N2;//these are the variables that will store the text of the string,the first number entered and the second.
        if(sscanf(cmdtext, "ii", N1, N2)) return SendClientMessage(playerid, -1, "Usage: /multiplay (1st number) (2nd number)");//this will send the player an error message if he enters invalid information or in a wrong format.
        format(str, sizeof(str), "The answer to %i x %i is %i", N1, N2, Answer);//this will format the answer and all the calculations and store it in the variable str.
        SendClientMessage(playerid,-1,str);//now this will send the information stored in the variable str to the player.
        return 1;
    }
    return 0;
}

correct & better one:

pawn Код:

#include <a_samp>//you all know this.
#include <sscanf2>//including sscanf include in the script.
#if defined FILTERSCRIPT

#endif
public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/plus", cmdtext, true, 10) == 0)
    {
        new str[128],N1,N2;//these are the variables that will store the text of the string,the first number entered and the second.
        if(sscanf(cmdtext, "ii", N1, N2)) return SendClientMessage(playerid, -1, "Usage: /plus (1st number) (2nd number)");//this will send the player an error message if he enters invalid information or in a wrong format.
        format(str, sizeof(str), "The answer to %i + %i is %i", N1, N2, N1 + N2);//this will format the answer and all the calculations and store it in the variable str.
        SendClientMessage(playerid,-1,str);//now this will send the information stored in the variable str to the player.
        return 1;
    }
    else if (strcmp("/minus", cmdtext, true, 10) == 0)
    {
        new str[128],N1,N2;//these are the variables that will store the text of the string,the first number entered and the second.
        if(sscanf(cmdtext, "ii", N1, N2)) return SendClientMessage(playerid, -1, "Usage: /minus (1st number) (2nd number)");//this will send the player an error message if he enters invalid information or in a wrong format.
        format(str, sizeof(str), "The answer to %i - %i is %i", N1, N2, N1 - N2);//this will format the answer and all the calculations and store it in the variable str.
        SendClientMessage(playerid,-1,str);//now this will send the information stored in the variable str to the player.
        return 1;
    }
    else if (strcmp("/multiplay", cmdtext, true, 10) == 0)
    {
        new str[128],N1,N2;//these are the variables that will store the text of the string,the first number entered and the second.
        if(sscanf(cmdtext, "ii", N1, N2)) return SendClientMessage(playerid, -1, "Usage: /multiplay (1st number) (2nd number)");//this will send the player an error message if he enters invalid information or in a wrong format.
        format(str, sizeof(str), "The answer to %i x %i is %i", N1, N2, N1 * N2);//this will format the answer and all the calculations and store it in the variable str.
        SendClientMessage(playerid,-1,str);//now this will send the information stored in the variable str to the player.
        return 1;
    }
    return 0;
}

PS: it should be /multiply not /multiplay

Glad some one test it,ThAnKs!

Re: Making Basic calculator commands. - Faisal_khan - 05.09.2012

Why are you putting the no. of characters of the command 10 though it is 9?

pawn Код:

strcmp("/multiplay", cmdtext, true, [B]10[/B]) == 0) }

It should be

pawn Код:

strcmp("/multiplay", cmdtext, true, [B]9[/B]) == 0) }

If you don't know what the fourth parameter stands for, it is the no. of characters in your command.
