[Wireframe] Block Scroller

[Raizor]

Here's my entry for the Wireframe compo.  Not quite managed what I'd hoped to achieve but at least I got something out the door before the deadline

The scroller is created using cubes to represent pixels from a 1 bit bitmap font. It's coded in C++ and uses iq's RGBA 64k framework. The music is by LizardKing (awesome musician imho).  I had a few issues due to being really rusty with C++ and WinAPI stuff, but hopefully the demo will run for most people.

I'll upload a video soon too.  The sourcecode is quite a mess at the moment, but if anyone wants it, I'll tidy it up and release it.

There seems to be an issue with slight jerking of the scroller sometimes, I think this is due to stepping in the sinus but I don't have time to dig into it

Thanks for reading and hopefully watching

Well it runs on my machine, but the scroller is so fast I cant read it and everything looks a blur, probably could do with some delta timing unless you were going for super fast

Looks nice and runs at constant 60 fps on my machine.
So TinDragon probably has VSync disabled?

[Raizor]

Thanks Hellfire and TinDragon.

Yeah, doesn't go over 60 fps here either. I think Hellfire is probably right TinDragon. Have you disabled VSync on your vid card?

Just x words, hang on i gotta count. It's six words: This is one bloody cool scroller! 

The widescreen detection is one neat feature too & it's nice to see a "newcomer" entry! Well done! 

Btw: I get 75fps here. And I have VSync enabled.

[Pixel_Outlaw]

Looks pretty neat!
Ran a bit fast on my machine too, (around 300-600 frames per second).
I was able to view it by clicking my mouse on the window and freezing it in place ever second or so.

[Raizor]

300-600 fps, a bit fast?? Oh dear. Sounds like something is amiss.

Thanks for the feedback

Will try and see if I can quickly limit the speed.

[Kirl]

200 fps here, single frames look cool though using Pixel_Outlaw's trick.

[Raizor]

I've attached a version with some forced vsync code. If the frame is rendering in under 16ms, it will block until the 16ms limit is hit.  It's a bit of a clunky fudge, but should hopefully stop the scroller flying along so far on certain machines. It might get a bit skippy though, due to the nature of the implementation.

If you don't need this version, I'd suggest using the other one. I've included both exe files in the attached zip.

Thanks for all the feedback so far, very useful and much appreciated

[Pixel_Outlaw]

Much better speed now. 

[Kirl]

Yep, good speed now. Loved it, awesomely colorful and blocky scroller. Happy to fry my retina's on this!

[Raizor]

Thank you Kirl and Pixel Outlaw

I have a soft spot for scrolls!  Nice job Raizor, good luck in the voting.

Welldone Dude!

New version runs at a readable speed, looks really nice as well. On the vsync front, I dont have it forced off but it is set to off/application controlled, so unless an app. puts it on its off. But I havent ever changed that setting that i know of

I'm not aware of a way to control vsync with OpenGL, so it looks like it's defaulting to whatever you card is set to. In your case this is 'disabled', so it races along.  Not sure of the workaround for this at the moment.  Thanks for the info though, it helps

There's an extension to set the swap-interval:

Code Select Expand


typedef BOOL (WINAPI *PFNWGLSWAPINTERVALEXTPROC)(int);
PFNWGLSWAPINTERVALEXTPROC wglSwapIntervalEXT =
   (PFNWGLSWAPINTERVALEXTPROC)wglGetProcAddress("wglSwapIntervalEXT");
if (wglSwapIntervalEXT)
   wglSwapIntervalEXT(1);


[Raizor]

Many thanks Hellfire

[benny!]

I really enjoyed this one. This scroll is one of the best scrolls I saw lately. Very well executed, mate.
It's cool to see you are back in C++ programming. Keep it up!

[Raizor]

Thank you Benny. It was good fun and I'm looking forward to doing bigger and better things in C++

I implemented you suggestions for my iPhone game by the way, single life etc.  Thanks again for those
