What are you working on? December 2011 Edition

[garry]

FYI web dev is for web design, webpages. This is the right place for programming.

[toaster468]

Is it possible to draw shapes in the console? That would be interesting for games and stuff.

EDIT:
Sorry wrong thread.

Should be fixed on nVidia cards now. I forgot to write a GL2 version of some shaders so if you have an old card it may not work. If it doesn't work for you please can you post your card and the highest OpenGL version supported by your drivers.

There's a known bug when you have a reflective surface crossing another surface, fixing that now.[/QUOTE]

nVidia GeForce GT 420M, I can't find what version of OpenGL it supports - but it supports DX10 if that's any help. Nothing happens when I open the game. Empty window.

[zenby]

I have an integrated intel card, also empty window

Nvidia GeForce GTX560Ti. Works perfect :D

Radeon HD 6850 works great. However, after like 50 mirrors are placed down, it lags like a mofo.

[DeadKiller987]

Why does it say G toggles 'ghost' and then later that it toggles colors?

Works great over here. NVidia GTX570, OpenGL 4.2.

This makes it lag horribly. :V
Also, frametime(FT) sometimes goes negative. :V

Does it work or not?

[Bang Train]

[QUOTE=Darwin226;33951068]No it isn't. Efficiency has nothing to do with that. If it was that important they would have written it in asm since the performance difference is negligible.[/QUOTE]

if()
goto:

is 1 je

vs

for()
{
     for()
     {
          ...
          if()
          {
               blah = true;
               break;
          }
     }
     if(blah)
          break;
}

thats 1 jne for the first if
1 register set to true (may involve copying an old register to memory to make room as well)
the jmp for break

then finally another je if blah is true.

so 1 instruction vs 4 instructions (possibly more if no available registers)

If it doesn't work for you try this: [url]http://anyhub.net/file/OKM-debug.7z[/url]
If it still doesn't work then can you upload the debug.log it generates and send it my way. Thank you everyone who has tested so far, I should note that in the game I'm hoping to use this in you will never get more than like 10 mirrors at a time.

Ghost was an old thing that I removed earlier today, forgot to take that text out though. Thanks for spotting it.

That's a relief, I tried to keep linux in mind while writing but I hadn't had time to test it myself.

If you need every cycle then you shouldn't be writing C.

[esalaka]

I don't know what you're even talking about but could it be for branching reasons?

Optimizing C/C++ on such a small scale is silly as the optimizer will do a way better job when compiling.

[QUOTE=Jookia;33955860]If you need every cycle then you shouldn't be writing C.[/QUOTE]

Sure, because bearing in mind small optimisations while writing code is only something you should only be doing in asm

Thank you. I'm working on this with a friend who thought of a game based on light, although I think he wants to keep the game idea secret for now so I can't say much more. You can guess that it will be a puzzle game.

I added a bunch of stuff like different signs for math.
and a beep noise when you get a problem wrong which weren't captured for some reason.

Unless the Linux kernel needs to break a nested loop a million times per second, it could do just fine with if statements.
Performance isn't the reason goto is used there. Linus just thinks that it doesn't harm the flow if used right, and I agree with that.
