Just make a timer that respawns the glass...
on top:

pawn Код:

new glassobject[//the amount of glass objects you have + 1 goes here];
forward RespawnGlass();

in OnGameModeInIt:

pawn Код:

SetTimer("RespawnGlass",7000,1);

whereever you create the glass do like this for each glass object:

pawn Код:

glassobject[0] = CreateObject(................);
glassobject[1] = CreateObject(................);
glassobject[2] = CreateObject(................);

and so on until you reach the last object.

in bottom of the script

pawn Код:

public RespawnGlass()
{
    for(new i; i < sizeof(glassobject); i++)
    {
        DestroyObject(glassobject[i]);
        switch (i) {
        case 0: glassobject[0] = CreateObject(//The first glass cordinates go here);
        case 1: glassobject[1] = CreateObject(//The second glass cordinates go here);
        case 2: //and so on....
        }
     }
     return 1;
}
