use this loop in command

pawn Code:

for(new i=0;i<MAX_VEHICLES;i++)
    {
        if(IsVehicleOccupied(i) == 0)
        {
            //DestroyVehicle(PlayerInfo[i][pSpawnVehicle]);  this is the line that is causing the error
            SetVehicleToRespawn(i);
        }
    }

First note this line from nativechecher

[debug] Accessing element at index 500 past array upper bound 499

Meaning:
This Line means that a array that has a size of 500 that means valid indexes in array are from 0 to 500-1, i.e., 0 to 499
The "500" in the message shows that error was caused when pawn tried to access 500th element/index of the array.
But as you see that valid locations are from 0 to 499 so it caused error

Tracing it:
To trace it down you have to find the array which are declared like this arr[500], arr[500][enum]...etc
Now as default value of MAX_PLAYERS is 500 and MAX_VEHICLES is 2000 so its obvious that array with MAX_PLAYERS is causing it and its obvious that pInfo is declared with MAX_PLAYERS, hence traced.

Why is it happening?

for(new i=0;i<MAX_VEHICLES;i++) { if(IsVehicleOccupied(i) == 0) { DestroyVehicle(PlayerInfo[i][pSpawnVehicle]);

As you can see loop is going from 0 to MAX_VEHICLES, i.e., 2000. But PlayerInfo is declared like this PlayerInfo[MAX_PLAYERS][enum], i.e., PlayerInfo[500][enum]
So here loop works fine till 499 index but as you try to access 500th index which is not valid, the script crashes
