Checking who's near you. - Shockey HD - 11.05.2012

How am i able to check to see who is near the person that type's /near and it displays there name in a format?

For an example, Lets say Tim is 10 feet away from me, I type /near and it says, "Tim is near you."?

use GetPlayerPos and IsPlayerInRangeOfPoint with Float:Distance 10 if thats what you want?

Use a Get Distance function:

pawn Код:

stock Float: GetDistanceToPoint(playerid,Float: X2,Float:Y2 ,Float: Z2)
{
    new Float:X,Float:Y,Float:Z;
    GetPlayerPos(playerid,X,Y,Z);
  return floatsqroot ( floatpower ( floatabs ( floatsub ( X , X2 ) ) , 2 ) + floatpower ( floatabs ( floatsub ( Y , Y2 ) ) , 2 ) + floatpower ( floatabs ( floatsub ( Z , Z2 ) ) , 2 ) );
}

================================================== ==================================
There are better distance functions (you can try IsPlayerInRangeOfPoint but I personally had issues with it. There are other distance functions around if you search a little), this is the one I had at hand.

In the command, create a loop through all the players and get the distance. If the distance is less than 10, Get the player name and format a message.
================================================== ==================================

A quick example I made up:

pawn Код:

stock Float: GetDistanceToPoint(playerid,Float: X2,Float:Y2 ,Float: Z2)
{
    new Float:X,Float:Y,Float:Z;
    GetPlayerPos(playerid,X,Y,Z);
  return floatsqroot ( floatpower ( floatabs ( floatsub ( X , X2 ) ) , 2 ) + floatpower ( floatabs ( floatsub ( Y , Y2 ) ) , 2 ) + floatpower ( floatabs ( floatsub ( Z , Z2 ) ) , 2 ) );
}

public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/nearme", cmdtext, true, 10) == 0)
    {
        new Float:pos[3];
        GetPlayerPos(playerid,ppos[0],ppos[1],ppos[2]);
        for (new i = 0; i<MAX_PLAYERS; i++)
        {
            if(GetDistanceToPoint(i,pos[0],pos[1],pos[2])<10)
            {
                new pname[MAX_PLAYER_NAME];
                GetPlayerName(i,pname,MAX_PLAYER_NAME);
                new string[64];
                format(string,sizeof(string),"%s(%i) is near you!",pname,i);
                SendClientMessage(playerid,0xFFFF00AA,string);
            }
        }
        return 1;
    }
    return 0;
}

You don't need GetDistance.

Using foreach.

pawn Код:

CMD:near(playerid, params[])
{
    new
        Float:x, // floats for the playerid's position
        Float:y,
        Float:z,
        name[24] // a new string for the all the names
    ;
    SendClientMessage(playerid, -1, "-------[ Players Near You ]-------");
    GetPlayerPos(playerid, x, y, z); // We get the position of the player and store them into the floats
    foreach(Player, i) // we loop through all the players
    {
        // and if all the players are within 10 feet of the playerid who typed this command's position.
        if(IsPlayerInRangeOfPoint(i, 10.0 ,x, y, z))
        {
            // then it will get their name and send it to who ever typed the command
            GetPlayerName(i, name, 24);
            SendClientMessage(playerid, -1, name);
            // since this is a loop
            // this code will be repeated
            // for EVERY player that is near whoever typed the command
        }
    }
    return 1;
}

Thank you very much.
