i am way confused maybe some one can make a code for me from this code

pawn Код:

if (strcmp("/coord", cmdtext, true, 10) == 0)
    {
    new t = playerid;
    new str[256];
    new Float:Pos[MAX_PLAYERS][4];
    GetPlayerPos(t,Pos[t][0],Pos[t][1],Pos[t][2]);
    GetPlayerFacingAngle(t,Pos[t][3]);
    
    format(str, 256,"x= %.4f y= %.4f z= %.4f a= %.4f",Pos[t][0],Pos[t][1],Pos[t][2],Pos[t][3]);
    SendClientMessage(playerid, 0xFF0000AA, "Thank You Your Coords And Vehicle ID Have Ben Saved");
    return 1;
    }
