Window / setKeyRepeatEnabled reverts to true if window.create is called...

« on: August 29, 2013, 08:37:50 pm »

...in the case of toggling full-screen after the app is running.

Noticed it today, similar to the vsync issue?
Didn't see it in the Issues list.

General discussions / Re: SFML Game Development -- A book on SFML

« on: August 28, 2013, 11:12:42 pm »

I've been moving stuff around the screen since I started with SFML 1.6, but the section on Vector Algebra stuck in my mind.

I've been moving objects like that, of course, but...Today it has solved for me (in one line of code), a tricky problem that made me 'nerdgasm' at how easy the solution actually was.

Thus far that alone is worth buying the book for. [read as: waking up a math dunce]

SFML wiki / Re: Simple Collision Detection for SFML 2

« on: August 19, 2013, 09:51:23 pm »

Wow, the bounding box code is actually readable now. 

Nice work. I'm yet to test the BB as most of my current stuff is circular collisions, but the original wiki BB code is right there in my project and I'd be happy to replace it with this!

Thanks for the contribution.

Window / Re: Help with implementing framelimit/correct timestep

« on: August 09, 2013, 12:49:06 am »

Also i asked about VSync hish CPU usage. Anybody had this problem?

Going back when I had an Nvidia card running SFML2 (RC) I remember having to change something in the driver control panel for a similar problem. The item in the control panel was Threaded Optimization (I switched it 'off' from 'auto'). Try that if you have an Nvidia card.

I also remember different behaviours between Windows Aero and Windows Basic themes.

I switched to use the "SFML Game Development" book's timestep code, an easy change, just a few lines. That works really well except for one minor issue which may be an ATI driver thing. Running the app after first boot or log-off/log-on causes a bad stutter that slowly and gradually corrects itself and everything is fine after 10secs (or if I restart the app). I only mention it here in case someone else has seen it too.

*Small update....I've had to reinstall my Nvidia card due to an intermittent BSOD issue on the Radeon HD6870. The above info is correct although it seems you need to run in a window or Window Style::None to see the correct CPU usage.

Feature requests / Re: Bézier curves

I only skim-read the post so forgive me if this is off the mark, but the Claw Library features support Bézier curves.

Good library, I use it principally for the Tweener.

I've just installed 2 having previously been using a RC version from last year and I've notoiced some impressive performance improvements on the CPU trace.

Nice work Laurent, and congrats on the new release!

This might be useful:

The code is simple to understand so easy to change to C++.

Graphics / How do I set a View position absolutley?

« on: August 09, 2012, 03:00:05 pm »

...or rather, what do you manipulate to do this?

With view zooming, it's setSize.

Thanks.

Graphics / Re: [SFML2] SetX/SetY disappeared ?

« on: August 06, 2012, 04:20:52 pm »

Agree with eXpl0it3r here. I used to be pretty much seperate X/Y mindset, but vectors are so much cleaner.

Window / Re: Weird Vsync CPU consumption?

« on: July 17, 2012, 10:07:30 am »

I found the reason why after searching the forums a little:
http://en.sfml-dev.org/forums/index.php?topic=7732.msg51443

I now have an ATI card and it will still do this, but only when using the W7 Basic theme and running in windowed mode.

I don't think the reported CPU usage is correct anyway, I remember pushing the number of objects to silly proportions and the frame-rate stayed solid 60 all the way with no slowing.

It's a non-problem, really. Perhaps annoying if you're on the lookout for real CPU spikes in your code, but like I said you can change the desktop theme for that.

Graphics / Sprite getRotation returning negative (2RC)

« on: July 15, 2012, 02:26:05 pm »

I looked around first, search wasn't working for me and didn't see anything on the tracker.

When I do a getRotation from a sprite, the result isn't between 0-360.

This...

sf::Sprite test;
test.rotate(-10);
cout << test.getRotation();

...will return a -10 instead of 350.

Getting a View's rotation is ok though.

Apologies if I've missed something, 1.6 had the documented behaviour.

Window / Breaking vertical sync

« on: July 07, 2012, 01:25:17 pm »

I just noticed that when using Windows 7 basic theme and running a Fullscreen window, alt-tabbing turns off vsync.

Thought I'd drop it in here in case it turns out to be bug for the tracker.

Window / Re: How to disable mouse but still read it?

I see.  The mouse move deltas were what I originally went looking for, +1 on that.
