4 Errors.

I get this from the below:

Code:

	for(new x;x<sizeof(LSPDVehicles);x++)
	{
	    format(string, sizeof(string), "XMT %d", LSPDVehicles[x]);LINE 223
	    SetVehicleNumberPlate(LSPDVehicles[x], string);
	    SetVehicleToRespawn(LSPDVehicles[x]);
		Vehicle_Armor(LSPDVehicles[x]);
	}

Code:

	for(new x;x<sizeof(LSPDVehicles);x++)
	{
            new string[128];
	    format(string, sizeof(string), "XMT %d", LSPDVehicles[x]);LINE 223
	    SetVehicleNumberPlate(LSPDVehicles[x], string);
	    SetVehicleToRespawn(LSPDVehicles[x]);
		Vehicle_Armor(LSPDVehicles[x]);
	}

2 important notices:

1. The string just is 4 characters + 1 integer. Why would you make it 128 bytes long? Even if the integer was at INTEGER_MAX, the string will never be longer than 14 chars. Add one for the closing string terminator for compatibility reasons, and youll end up with
new string[15];
as the smallest (and so optimal) string size. You can use even smaller values, but that depends on how big the LSPDVehicles numbers can be.

2. Always put variable definitions before the loop, not inside of it. Why would you create and destroy the same variable 1000 times, if its enough if you just define it once.

Small optimisations like this can make the difference between a well-running server and a laggy adventure.

1. Well it was for example the 128 byte thing! I didn't knew how many bytes he needed!

2. Thanks i didn't knew that
