How can i make that every 20 minutes played time player get some reward?

You have to set player timer (SetTimerEx) for 20 minutes and than create
forward + public and there you can add your reward!

Something like this is will do what you want. You can declare the timer in OnPlayerConnect instead of OnPlayerSpawn, that's up to you.

pawn Код:

public OnPlayerSpawn(playerid)
{
    SetTimer("reward", 1200000, 1); // Creates a timer called "reward", repeated every 20 minutes (1200000ms).
    return 1;
}

forward reward();
public reward()
{
    //Rewards
    return 1;
}
