    [TUTORIAL]Server optimisation
     
     
    Hello! I've been searching for server optimisations and I was not content about the topics i just found out. So, there are some simple methods to optimise your script.
    1. If you are using samp timers you should definitely use y_timers. Ysi timers will reduce server's lag if you have a lot of timers and they will be more stable. There are 2 types of timers:
    Task: are called constantly at a given period.
    How to define them? There is an example:
    task SomeFunction[1000]() { and your code } . The tasks don't need any calling, they will begin on gamemode/sever start and are running until the server stops.
    ptask SomePlayerFunction[1000](playerid) { and your code } . You don't have to use anymore SetTimerEx.
    Timers: they need a calling.
    How to define them? An example:
    timer SomeTimer[500](playerid) { your code } . If you want that timer to run you have to call it. The are some ways to do that:
    repeat: the timer will repeat(exactly as you do with SetTimer("blabla", 1000, true)) until you stop it. Example: repeat SomeTimer();
    defer: this calls the function once after the time defined. Example: defer SomeTimer();
    normal call: Just use the function where you need so. For example: SomeTimer();
    How to stop a timer? Simply use stop: if you have defined your timer (new Timer:MyTimer) you can stop it on gamemodeexit or where you want the timer to stop like that: stop MyTimer; If you want to make a timer and verify it to see if it's active you should do that:
    new Timer:MyTimer[MAX_PLAYERS] = {Timer:-1, ...}; To check if the timer is active just use this condition: if(MyTimer[playerid] != Timer:-1).
    This check if the timer is active and will return true if so. To stop it you can do that: if(MyTimer[playerid] != Timer:-1) { stop MyTimer[playerid]; MyTimer[playerid] = Timer:-1; }
    To activate MyTimer to use a function I can simply do that: MyTimer[playerid] = repeat SomeTimer(playerid);
    You can edit repeating interval for one calling if you want so. For example i want SomeTimer to run at 2000 miliseconds instead of 1000. So, i wil use: repeat SomeTimer [2 * 1000]();
    I highly reccomend using TASKS ONLY for GLOBAL timers and timers for PLAYER timers.

    2. Define MAX_PLAYERS to your server's slots. How to do that? Simply, at the beginning of your gamemode use:
    #undef MAX_PLAYERS
    #define MAX_PLAYERS MySlots(for example, 50)

    3.Use foreach instead of MAX_PLAYERS or GetPlayerPoolSize loops. How to do that? Include foreach at the top of your gamemode(#include foreach) and use it where your are doing a loop with MAX_PLAYERS. How to do that? instead of for(new i; i< MAX_PLAYERS; i++) use foreach(new i: Player).

    4.Use GetVehiclePoolSize/Iterators instead of MAX_VEHICLES loops. How to do that? Instead of for(new i; i<MAX_VEHICLES; i++) use for(new i = 0, j = GetVehiclePoolSize(); i < j; i++) or create an iterator. You have to include y_iterate at the top of your gamemode(#include y_iterate) and y_hooks(#include y_hooks) so you can use them. To create an iterator you simply use: new IteratorerverVehicles[MAX_VEHICLES]. This will add an iterator named ServerVehicles with max vehicle containing of 2000(or your max_vehicles value). To add vehicles in the iterator just use: Iter_Add(ServerVehicles, vehicleid); to remove: Iter_Remove(ServerVehicles, vehicleid).
    Iterator functions:
    Add: this will add objects in the iterator. Iter_Add(itername, iterobject);
    Remove: this will remove an object in the iterator. Iter_Remove(itername, iterobject);
    Free: checks if there is a free object slot in the iterator(if i have 200 vehicles in the iterator and i will add one more my vehicle id will be 201, so less than 2000).
    Contains: checks if there is an specific object in the iterator. It's good for checking before deleting something from the iterator. Iter_Contains(itername, iterobject);
    Count: counts the objects in the iterator. Iter_Count(itername);

    5. Use lower strings. If you have a text of 128 chars don't make a string of 200. Use it as 128. You have some chars limits in chat/message. Check this: https://wiki.sa-mp.com/wiki/Limits

    That's all I have in mind for now. Also, you could use C# or C++ to script your gamemode for scratch, but that's for another tutorial. I hope i helped you!
