Pawn GetPlayerPos and show in chat?

LagunaPreza · 2020-12-19, 05:48 PM

Hey all,

I'm new to the whole pawn scripting and I try to make a command that gives me my position.
But, when I use the command it doesn't send anything in the chat.

Code:
if (strcmp("/getpos", cmdtext, true, 7) == 0)

{

// Do something here

new Float:x, Float:y, Float:z;

GetPlayerPos(playerid, x, y, z);

SendClientMessage(playerid, -1,"Position: %f, %f, %f.", x, y, z);

return 1;

}

return 0;

I've also tried to remove the %f, %f, %f part but then it only sends me "Position:" without the actual player position.
Also when I compile/run my script, it gives me 3 warnings(warning 202: number of arguments does not match definition)

Any help would be appreciated.

You can't pass arguments to most of the native functions (naturally including SendClientMessage)

You need to use format before, like this:

Code:
if (strcmp("/getpos", cmdtext, true, 7) == 0)

{

// Do something here

// 64 is the size of the string

new buffer[64], Float:x, Float:y, Float:z;

GetPlayerPos(playerid, x, y, z);

format(buffer, sizeof(buffer), "Position: %f, %f, %f.", x, y, z);

SendClientMessage(playerid, -1, buffer);

return 1;

}

return 0;

There is also an extended version of SendClientMessage which does receive parameters.

Code:
stock SendClientMessageEx(playerid, color, const str[], {Float,_}:...)

{

    static args, start, end,string[200];

    #emit LOAD.S.pri 8

    #emit STOR.pri args

    if (args > 12)

    {

        #emit ADDR.pri str

        #emit STOR.pri start

        for (end = start + (args - 12); end > start; end -= 4)

        {

            #emit LREF.pri end

            #emit PUSH.pri

        }

        #emit PUSH.S str

        #emit PUSH.C 156

        #emit PUSH.C string

        #emit PUSH.C args

        #emit SYSREQ.C format

        SendClientMessage(playerid, color, string);

        #emit LCTRL 5

        #emit SCTRL 4

        #emit RETN

    }

    return SendClientMessage(playerid, color, str);

}

That's a terrible one at that, they should use va_SendClientMessage

Why is that?
