TimeSources are broken

[darkgunner89]

Hi,

Just tested this library for the first time in my project, and noticed my time sources not working and not even "existing".

So I tested it in a dummy project with just 1 simple object in 1 room that creates a TimeSource that prints "Hello World" every 2 seconds:

// Create Event
var helloWorldRepeatingTimeSource = time_source_create(time_source_game, 2, time_source_units_seconds,
		show_debug_message, ["Hello World"], -1);
		
if(time_source_exists(helloWorldRepeatingTimeSource)){
	show_debug_message("TimeSource exists after creation");
}else{
	show_debug_message("TimeSource DOES'T exist after creation");
}
		
time_source_start(helloWorldRepeatingTimeSource);
		
if(time_source_exists(helloWorldRepeatingTimeSource)){
	show_debug_message("TimeSource exists after starting");
}else{
	show_debug_message("TimeSource DOES'T exist after starting");
}

• Before loading this library, the timesource works

• After loading the library, the timesource doesn't work, it doesn't print anything, and it's not recognized as "existing" after creating it

I'll attach here the dummy project:
gamemaker_debug_time_sources_with_testing_library.zip

This was tested in Windows 10 with GameMaker LTS2026.

Please let me know if I missed anything.

Thanks in advance!!

Is it because my objects and their timesources are created BEFORE the tests are run, and there is a condition that says "if the tests have finished, create normal timesources; if not, create mocked ones for tests"?

Is it somehow my fault? Shouldn't the tests be run before anything is created in the game?

Sorry in advance if this ends up being my fault... And also thanks in advance for your time and your hard work!

PS: I'm a bit afraid that this library might run the tests too late, and other code that creates TimeSources create mocked/simulated ones, instead of real TimeSources. And not only my own code, for example the super awesome and useful Input or Scribble libraries:

EDIT: I found where we can set how many frames to wait to run the tests:

Although setting it to a low value (0, 2...) makes it crash:

As a workaround, I could set the gmtl_run_at_start above that line to false when running the game, and to true when I want to run the tests I guess.

EDIT 2: By the way, I think what you did was amazing! Please don't misunderstand me , I'm very thankful for the work you did in this library ^^

Thanks for reporting! As far as I remember this shouldn't be failing the way you are implementing it. I will take a look into it and add/update some test case scenarios to validate it's working. Will let you know here when the fix is done and released!

@darkgunner89 I just released v1.2.1. I did some manual testing and added some test scenarios to be sure it fixes the error, as far as I tested with the demo project you sent, this is the output:

Let me know if it resolved your issue so I can close it!

[darkgunner89]

It seems it works, thank you very very much for your hard work!! I guess you can close it 😄

BTW I added you (before you even fixed it, you made a great job with this library) to the future credits of my future WIP game 😄 (too early to show anything yet though):

Thank you again! Have a nice day!
