if you want only admins use that command, put this way

pawn Код:

CMD:skydive(playerid, params[])
{
    if(IsPlayerLuxAdminLevel(playerid,3) || IsPlayerAdmin(playerid));
    {
        new Float:pPos[3], km;
        if(sscanf(params, "i", km)) return SendClientMessage(playerid, COLOR_RED, "John: /skydive [meters]");
        if(km <= -1 || km >= 3001) return SendClientMessage(playerid, COLOR_RED, "John: You cannot use negative amount or amounts higher than 3000! Its too Dangerous!");
        if(GetPlayerWeapon(playerid) != 46) return SendClientMessage(playerid, COLOR_RED, "John: Probably would've been better with a /chute...");
        if(IsPlayerInWater(playerid))return SendClientMessage(playerid, COLOR_RED, "John: You cannot be force pushed while in water!");
        GetPlayerPos(playerid,pPos[0],pPos[1],pPos[2]);
        SetPlayerPos(playerid,pPos[0],pPos[1],pPos[2]+km);
    }
    else SendClientMessage(playerid, COLOR_RED, "Error: You are not an Admin!");
    return 1;
}

or if you want only player uses that command use;

pawn Код:

CMD:skydive(playerid, params[])
{
    if(IsPlayerLuxAdmin(playerid) || !IsPlayerAdmin(playerid));
    {
        new Float:pPos[3], km;
        if(sscanf(params, "i", km)) return SendClientMessage(playerid, COLOR_RED, "John: /skydive [meters]");
        if(km <= -1 || km >= 3001) return SendClientMessage(playerid, COLOR_RED, "John: You cannot use negative amount or amounts higher than 3000! Its too Dangerous!");
        if(GetPlayerWeapon(playerid) != 46) return SendClientMessage(playerid, COLOR_RED, "John: Probably would've been better with a /chute...");
        if(IsPlayerInWater(playerid))return SendClientMessage(playerid, COLOR_RED, "John: You cannot be force pushed while in water!");
        GetPlayerPos(playerid,pPos[0],pPos[1],pPos[2]);
        SetPlayerPos(playerid,pPos[0],pPos[1],pPos[2]+km);
    }
    else SendClientMessage(playerid, COLOR_RED, "Error: You are not an player!");
    return 1;
}
