i really need help.. please someone can give me that stock?

Re: help | Some question - Bufige - 12.10.2012

Just made this, compiles fine and should be working.

PHP код:



stock closestplayer(playerid,&Float:distance = 9999999.0)

{

    static player, Float:x ,Float:y ,Float:z , Float:olddistance , closestid;

    for(player = GetMaxPlayers(); player > -1; --player)

    {

        if(!IsPlayerConnected(player)) continue;

        GetPlayerPos(player,x,y,z);

        if((olddistance = GetPlayerDistanceFromPoint(playerid, x, y, z)) < distance)

        {

           distance = olddistance;

           closestid = player;

        }

    }

    return closestid;

}


// usage:

new id,Float:dis;

id = closestplayer(playerid,dis);

printf("Player ID - %d, Player Distance %f",id,dis);

PHP код:



    if(IsKeyJustDown(KEY_CTRL_BACK,newkeys,oldkeys) && NeonFire[playerid] == 1)

{

    if(BlockNeon[playerid] == 1) return 0;

    new Float:v_x,Float:v_y,Float:v_z,

    Float:x,Float:y,Float:z,

    Float:pX,Float:pY,Float:pZ,

    Float:iX,Float:iY,Float:iZ;

    for(new i; i< MAX_PLAYERS; i++)

{

    if(IsPlayerConnected(i))

{

    new Float:range;

    i =  closestplayer(playerid,range);

    GetPlayerCameraFrontVector(playerid,v_x,v_y,v_z);

    GetPlayerCameraPos(playerid,x,y,z);

    GetPlayerPos(playerid,pX,pY,pZ);

    GetPlayerPos(i,iX,iY,iZ);

    T_SetPlayerLookAt(playerid,v_x*500.0+x,v_y*500.0+y);

    NeonObj = CreateObject(18648,pX,pY,pZ,0,0,0,200);

    MoveObject(NeonObj,iX*500.0+iX,iY*500.0+y,iZ,3,0.0,0.0,0.0);

    NeonTimer = SetTimerEx("CheckPos",5000,0,"i",i);

    BlockNeon[playerid] = 1;

}

}

}

look at this code, i tried to check the closest player, and to his pos the object will move, it create too many objects, and then crash the game

That code always returns 0!, if you use it like in your example....

pawn Код:

#define INFINITY (Float: 0x7F800000)

pawn Код:

stock GetClosestPlayer(playerid, & Float: distance) {
    new
        Float: X,
        Float: Y,
        Float: Z
    ;
    if(GetPlayerPos(playerid, X, Y, Z)) {
        new
            i,
            Float: dis,
            closest = INVALID_PLAYER_ID
        ;
        for(distance = INFINITY; i != MAX_PLAYERS; ++i) {
            if(0.0 < (dis = GetPlayerDistanceFromPoint(i, X, Y, Z)) < distance) {
                distance = dis;
                closest = i;
            }
        }
        return closestid;
    }
    return INVALID_PLAYER_ID;
}

Remove the loop... you only need to call the function once

Re: help | Some question - tomsalmon - 12.10.2012

You can bring me a loop to check each server except playerid players, because it check the closest of playerid to playerid...
