YSI Logic user-incomprehension and usage - hastlaking - 2019-12-17
Hello Community, i have this odd incomprehension with the YSI Libraries and most-partial of the documentation is missing or not yet implemented (explanation) into github repository i might say.

Tell us more about the parts of YSI you are having issues with?
RE: YSI Logic user-incomprehension and usage - hastlaking - 2019-12-18
mainly with timers calling them once on few public callbacks and some to initialize when needed example when player the moment the are logged in

Okay, so timers come in two forms, one being a regular timer and another being a repeater. A regular timer has a keyword associated with it called `defer` which means to delay a call to a function, now you can defer a function for n times, n being the number of milliseconds you wish to delay.
An example of this would go as follows:
Code:
main()
{
? ? // uses the 'defer' keyword to associated it with YSI,
? ? // and a function name and it's parameters is required afterwards?
? ? defer CheckPlayer(12);
? ? // You can override the delay set on the timer function, which is enclosed
? ? // in square brackets `[500]` by also putting square brackets with a new timer
? ? // delay inbetween?
? ? defer CheckPlayer[1000](12); // this will override the delay in the function and instead wait 1 second
? ??
}
// The 'timer' is a keyword that YSI uses to associated this function with YSI
// The number enclosed within square brackets `[500]` is the number of seconds the timer
// will be delayed for
timer CheckPlayer[500](playerid)
{
? ? // Perform some checks, or what you would normally do if this was a standard timer (SetTimer(Ex))
? ? if(IsPlayerConnected(playerid)) {
? ? ? ? printf("The player is connected");
? ? }
}We than have repeatable timers. These timers run until manually stopped, and they can be stopped by using the `stop` keyword. To create a repeatable timer, you instead use the `repeat` keyword instead of the `defer` keyword. Here is an example:
Code:
static Timer: repeatable_timer;
main()
{
? ? // Here we are storing the timer globally, so it can later be stopped else
? ? // where in the script. Though this is only needed if the timer is to ever be stopped
? ? // timers are generally managed internally to YSI, so will be stopped when the server exits
? ? // or when the gamemode ends.
? ? repeatable_timer = repeat CheckPlayer(12);
? ? // We can also override the default delay for the function
? ? repeatable_timer = repeat CheckPlayer[1000](12); // The delay value is overridden to run every 1 second
}
// The 'timer' is a keyword that YSI uses to associated this function with YSI
// The number enclosed within square brackets `[500]` is the number of seconds the timer
// will be delayed for
timer CheckPlayer[500](playerid)
{
// Perform some checks, or what you would normally do if this was a standard timer (SetTimer(Ex))
if(IsPlayerConnected(playerid)) {
printf("The player is connected");
}
// Lets now stop the repeatable timer just as an example
stop repeatable_timer;
}I hope this is enough to make you understand when to use them and how to use them. Feel free to ask anymore questions :)
