Do you get an error output in the console for the font?

I did get text to draw before I uploaded that code, so I wonder if something broke later.

In any case, I do get an invalid memory error on my end when using a Font object which may explain your crash. I'll get this fixed too!

This is what happens when I don't write unit tests as soon as I write the code. :P

Jebbs commented on June 8, 2024

But nothing from DSFML about an invalid font? Interesting.

I'll track down that invalid pointer issue though, and that should fix the crash.

from dsfml.

Jebbs commented on June 8, 2024

Latest commit to DSFML-C fixes the crashing at exit, but it is late so I will work on the drawing part tomorrow!

from dsfml.

aubade commented on June 8, 2024

Unfortunately, it's still crashing at exit for me. :( It looks like it's trying to destroy a non-existent texture? At least according to the backtrace it's crashing in dsfml.graphics.texture.Texture.__dtor()

from dsfml.

aubade commented on June 8, 2024

Though, on the bright side, I just realized that while testing with DMD, I've been making 64-bit binaries. 32-bit ones are having the exact same difficulties, but at least 64-bit DMD binaries work now :)

from dsfml.

Jebbs commented on June 8, 2024

Oh, interesting. I didn't actually load a font though. I thought it was something else, but it looks like I fixed a different bug. :P

from dsfml.

Jebbs commented on June 8, 2024

That's super great about building in 64 bits though! I'm gonna stop worrying about that completely. :)

from dsfml.

Jebbs commented on June 8, 2024

I can replicate the text not drawing, but I don't experience the crash on Windows. If I can't seem to track it down, then I'll get a VM going to see if maybe that'll help pinpoint it.

from dsfml.

Jebbs commented on June 8, 2024

If you don't create the text object, does the crash still happen?

from dsfml.

aubade commented on June 8, 2024

Nope! No crash if I don't create a Text object. And it wouldn't surprise me too much if it's OS-specific. We've seen a couple instances already of D's GC acting differently on Windows and Linux.

from dsfml.

Jebbs commented on June 8, 2024

I would be willing to bet the two problems are closely related. I'll see what I can do!

Any other problems you've noticed since then?

from dsfml.

aubade commented on June 8, 2024

Not yet. :) Sprites, Circleshapes, rectangleshapes, and vertexarrays all seem to be working. I haven't integrated any sound code into my engine proper yet,but later today, I'll poke again at my sfmod and sfmidi stuff. :)

from dsfml.

Jebbs commented on June 8, 2024

I'm pretty confident you won't have any issues there. I haven't really changed much since the last time you said it worked.

from dsfml.

Jebbs commented on June 8, 2024

I just found out that drawing text does work....sort of. I got it to draw by setting the fields individually. Not sure if order matters. Good news is that I should have a fix for it today. Bad news is that I have no idea what is causing that crash, but I'll keep fiddling.

from dsfml.

Jebbs commented on June 8, 2024

Well, I found out why it wasn't drawing for you. And it's the dumbest reason ever.

I totally forgot to have everything update when you set the color, and I also realized that I forgot to add the alpha fix in color.d, so you would never see anything unless you update something else AFTER you set the color. I can fix both of these very easily and it will only take a few seconds.

You'll at least be able to draw text again!

Now to figure out what is causing your stupid crash...

from dsfml.

Jebbs commented on June 8, 2024

There! You should be able to see your text now!

from dsfml.

aubade commented on June 8, 2024

Okay! It is displaying text! But... numbers aren't coming through correctly at all. I'm converting some basic debug data to a string at runtime and displaying it in a Text object. writeln()-ing it to stdout looks okay, but it prints one or two digits of the number, and a lot of spaces.

If I'm not explaining it well enough, I can make a quick youtube video to show the weirdness. It's actually kinda trippy.

from dsfml.

aubade commented on June 8, 2024

https://www.youtube.com/watch?v=sFezzCdxSq8 is what it looked like using the old branch of DSFML. The debug text shows the framerate, and the player's position.

https://www.youtube.com/watch?v=LcI85g1f0OU is running on the experimental DSFML branch. Outputting the same string with writeln() looks the same as in the first video.

from dsfml.

aubade commented on June 8, 2024

...after a closer glance, it looks like it's displaying the numbers, but just substituting blank spaces for any digits that aren't 8, 6, or 0... and considering the starting framerate is going to read 0, and the player's starting coordinates are (60, 80), I think the problem is that if you change the string, it won't correctly display any characters that weren't also there in the initial string.

from dsfml.

Jebbs commented on June 8, 2024

Wow, that is just freaking the hell out isn't it? I never thought to check drawing with numbers. That is a pretty serious issue so I'll make sure to get it fixed asap.

Unfortunately I don't know the Text code that well. It was mostly me just copy pasting, so it might take a while to track down the actual cause.

from dsfml.

aubade commented on June 8, 2024

After a little further futzing, my theory seems to pan out--changing the initial position to 123, 456 made those digits show up, but not 7, 8, or 9. So it does appear that only glyphs present in the initial string are properly displayed.

from dsfml.

Jebbs commented on June 8, 2024

Yep, I had the same thing happen to me. I do have something I can try tomorrow though. I was just very busy today.

from dsfml.

Jebbs commented on June 8, 2024

Made some changes and now things draw like they should, but it causes a crash somewhere.

Making progress though!

from dsfml.

Jebbs commented on June 8, 2024

If I can't figure out what is going on by Wednesday, I'll revert to using the CSFML type method of doing the Text class since we both know it worked right. If that happens I'll just mess with it later to try to fix what ever is going on.

I think it's something that probably just isn't translating very well when going from C/C++ to D. Fixing it is a much better solution than going back to the CSFML style, so what I'll probably do long term is create a new kind of C++ Text class that produces a vertex array, and then make a wrapper around that.

from dsfml.

aubade commented on June 8, 2024

Alright. :) I'm sorry it's such a pain!

from dsfml.

Jebbs commented on June 8, 2024

That's what I get for undertaking this project I guess :P

I'm just glad you saw it! I was nearly ready to release/announce on the D forums and everything. I would have been pretty embarrassed if everyone in the D community that tried it found stuff broken already.

from dsfml.

Jebbs commented on June 8, 2024

Don't get excited just yet, but I'm pretty sure I just found out how to fix the text not displaying properly AND your texture pointer crash.

I get off work in a couple of hours, so I'm not sure when I'll upload anything, but you should get it working tonight!

from dsfml.

Jebbs commented on June 8, 2024

I have something I'd like you to test. Are you loading the font from a file?

I have some more that I want to do to make sure everything is working the way it should, but I want to make sure that this idea is going to pan out.

from dsfml.

aubade commented on June 8, 2024

Yes, I am loading from a file--I haven't yet tested Streams or Memory loading.

from dsfml.

aubade commented on June 8, 2024

(Eventually I will be loading through a stream using PhysFS, but since we didn't have InputStreams till just now, I haven't set up the code for that yet.

from dsfml.

Jebbs commented on June 8, 2024

I need to clean up some code, but it should at least do the trick.

I made some changes to DSFML-C and DSFML so you'll need to recompile both. It fixes the issue with the font not updating correctly for me(and should for you too), and you shouldn't be trying to delete objects that no longer exist anymore. ;)

from dsfml.

aubade commented on June 8, 2024

Seems to work :) No exit-time crash. and all the numbers display well!

from dsfml.

Jebbs commented on June 8, 2024

Huzzah!

I'll finish cleaning everything up, maybe do a couple of more tests, and then I'll close this up.

from dsfml.

aubade commented on June 8, 2024

Uh oh! Sorry. I just did a quick implementation of an InputStream--loading from it reported success, but then the Text didn't work. I'll poke around a bit and file a new bug for that if it affects more than Fonts. :)

from dsfml.

aubade commented on June 8, 2024

Yup! Loads an image from a stream just fine, but loading a Font made it crash, when trying to actually do the draw operation

That's because I haven't quite finished it yet. I wanted to make sure my idea actually worked before I implemented it for all if the ways you can load.

I'll get to it soon enough though! Probably tomorrow. No needed for a new issue in the tracker.

Alrighty :) I was only going to file a new issue if other stuff didn't load right from a stream.

Jebbs commented on June 8, 2024

Ah, gotcha. I think I only did a test with loading a image, but everything should be set up the same. Assuming you don't find any other problems I'll start writing unit tests on Tuesday. Hopefully that will flush out any other missed stuff.

wince loading Music from a stream isn't working either...

Jebbs commented on June 8, 2024

Hmm. Well I'll make sure to run a test tomorrow. What most likely happened is that I just didn't quite finish setting it up.

Jebbs commented on June 8, 2024

Yep, just looked at some code and that is exactly what happened. I'll fix that today.

Sorry you keep finding broken/unfinished stuff. :(

aubade commented on June 8, 2024

Hey, it's totally fine. I'm sorry I keep pushing back the release date :)

If I haven't mentioned it before, or enough, I <3 DSFML, and you're pretty awesome for going through all this work to maintain it :)

Jebbs commented on June 8, 2024

Thanks for the kind words. I really appreciate it. :)

I finished up the font and text stuff, and the stream loading for music and sounds should work now too!

We're close! Unless there's some D-side changes that I'm not able to pick up yet, it looks like we're closer but not quite there yet. Font isn't crashing, and Music isn't crashing on load.

Unfortunately, a stream-loaded font is displaying as all while squares, and stream-loaded Music is crashing when I try to play it. Both work fine when loaded directly from a file.

If it's of any help, the audio backtrace is now:

EDIT: The audio crash might be something weird on my system, or with compiler optimization, because passing the length of the void array directly to physfs crashed, but caching it in a local variable and passing that to physfs didn't.

EDIT2: Even weirder. the local variable trick works when the engine is compiled with -O2, but it crashes when optimization is disabled.

Interesting. I think we should open up a different issue for the InputStream sound errors though. One problem at a time ;)

I know what happened with the Text not displaying though. It was just because I forgot to finish everything up for my fix with the other loading types in the loadFrom methods. You were drawing quads with no textures. It also looks like some of my changes failed to upload correctly, so I got those to commit.

The font should finally be fixed!(fingers crossed)

aubade commented on June 8, 2024

Font works now! I'll make an issue for the Music crash.

from dsfml.

Jebbs commented on June 8, 2024

Cool!

I already told denizzzka that I will be working on his issue after I finished with this one so it might take some time before I get to it.

I'm gonna close this finally. :D
