<1> SDL_ttf is refusing to open fonts -.-
<2> is there any way to do SDL_LoadBitmap etc with a memory pointer as a source?
<1> given that it takes a const char *, I don't think so
<1> You'd have to rewrite the function
<3> See if SDL_CreateRGBSurfaceFrom will do what you're looking for.
<3> lerc_ that is.^
<2> Acutally Found what I was looking for with SDL_LoadBMP_RW
<1> TTF_Open still isn't working for me :(
<2> No help from me sorry (2 day SDL noob).
<1> oh wait
<1> ffs
<1> *glares at sample code*
<3> what's going wrong?
<1> it had if (!font)
<1> I change to if (font != NULL) and it works
<1> or not
<1> missed the !
<1> TTF_Open refuses to open a font
<1> the file is there
<3> what's TTF_GetError report?
<1> sec
<1> nothing
<3> paste your code into a pastebin
<1> Warning: unlink(/home/pastebin/public_html/../cache/recent): No such file or directory in /home/pastebin/lib/pastebin/db.mysql.cl***.php on line 243
<1> Not very heartening XD
<1> Sec, I'll copy the sourcefile onto my publci_html
<1> public_html*

<1> http://gotenxiao.servehttp.com/~goten/other/sdltest.html if you want syntax highlighting
<4> GotenXiao: your initFont() has a missing return 0; and the test should be if (font == NULL) or just if (!font)
<1> I literally just spotted the !=
<1> and thanks about the return, hadn't spotted that one
<5> kendrick: hi
<6> What?
<6> SDL is shareware now?!
<6> too tired
<7> hehe
<8> :P
<9> has there been an issue with 64bit SDL?
<9> and... Mono
<9> (or .GNU)
<10> re
<11> Archon: boo
<9> juvinious: who are you?
<11> nobody
<9> juvinious: ok... you remind me of someone from another channel
<8> Does SDL change the way the program calculates with floats?
<8> Because I get different answers depending on whether I initialize the SDL-window or not
<1> o.O
<12> O-o
<1> What're you calculating?
<8> physics simulation
<8> mostly with doubles actually
<12> are you comparing equality of doubles?
<8> nope I'm not
<8> the simulation just goes in a different way due to cumulative calculating errors without the window
<8> errors as differences
<8> with screen it takes 25.565 seconds (with 5 ms time steps), without it does 25.570
<8> and if I take a longer simulation, the error is horrible
<12> you're not dealing enough well with your timing
<12> are you relying on SDL_GetTicks?
<8> nope
<8> SDL_GetTicks only tells me when to calculate the next physics step, but isn't used for anything else
<13> The floats are larger precision in registers. Using different code might force different register usage and force some calcs to mem temporarily where they drop precision.
<8> mmh..
<8> this is really weird
<8> lercOsX: well..
<13> in general, Floating point is usually defined to be within a levelk of precsision but not neccisarily determanistic.
<8> well..
<8> are there, like, any flags to feed gcc with, to get a dirty workaround of this?
<8> *for
<13> To force determanism you have to quantize to a level of precision below the defined accuracy.
<8> hmm :b
<13> for instance any values you keep to 100 significan digits you chop off at 80 significant digits periodically.
<8> urgh..
<8> that's not fun
<13> As long as you do the quantization often enough that errors don't accumulate up to the 80th significan digit it'll stay deterministic.
<13> Has to be done. You'll find AMD and intel can be quite different. Not to mention PPC.
<8> okay
<8> is there an easy way to do that or do I need to go anding the bits or something? :)
<8> are you sure that SDL doesn't change the rounding mode?
<13> it may do. But I've had things like Sound card drivers do that to me when they play sounds. (grumble creative labs)
<8> oh
<8> okay, I found out how to check which mode is in use but have no idea of how to change it
<8> if it's even possible
<8> well, I suppose it isn't
<8> okay, got it
<7> hehe: -ChanServ- [#SDL] Welcome to #sdl - The Offical Simple DirectMedia Layer Channel
<7> offical
<12> it is
<7> probably need to s/offical/official/ :)
<12> ah, true :)
<12> that's how I used to typo it too
<14> hmm...
<14> how do i rotate a surface ?
<14> i don't see any function to let me do that O_O
<14> this is gonna be uber lame if i can't
<15> that's outside of SDL's scope
<14> are you serious.
<14> how would i do it then ?
<14> i'm gonna have to kill someone if i can't rotate a surface
<9> ChrOnX: you could use OpenGL to rotate a quad
<15> per hand or via one of the extension libs that does it
<14> what lib lets me do it ?
<14> any ideas ?
<15> i wont look it up for you
<9> ChrOnX: do you mean, rotate a surface that is blitted to the screen, or to shift the suface's source?
<14> i don't know what to look for
<14> i need to rotate the surface that is being drawn
<15> you are either lazy or stupid
<14> thanks
<14> for that constructive criticism
<15> you didnt even spend 20 seconds looking for it before asking
<15> which is a sure sign that you don't value other people's time
<9> ChrOnX: i don't use SDL but if it doesn't have a rotate drawing function then perhaps you should invest interest in OpenGL or Allegro
<15> if you want help you better show some effort of your own as well
<14> i can't find any libs that allow for rotation
<14> all i see is "surface rotation is expensive do make a sprite sheet with each rotation on it and just load a specific part of it for a rotation"
<14> that won't help me because i need every degree
<16> can't you use SDL_gfx and rotozoom?
<14> hmm i can't find the download
<14> for SDL_gfx
<16> http://www.ferzkopp.net/Software/SDL_gfx-2.0/
<14> sweet
<0> that looks nice :D

<16> why does my app crash?
<14> which paste ?
<16> well, both
<14> what do you mean by "crash" ?
<14> just stop responding ?
<14> or runtime error ?
<16> I'm running it on win xp
<14> what happens ?
<16> it just asks if I want to send some crash report to microsoft
<16> you know
<14> run time error
<14> hmm
<16> and the worst thing is that I haven't got a clue why it crashes
<14> i think its somewhere in Free_Surface
<1> anyone done blitting from SDL_Surfaces to OpenGL textures?
<15> NitrotriggeR: run it through a debugger and find out in which line
<15> you don't blit from surfaces to textures ... but you can upload the one as the other
<15> there's an example for that in the source dist test directory ... a few SDL ports of the nehe tutorials show it as well
<3> GotenXiao, yes, check this page: http://www.gamedev.net/community/forums/topic.asp?topic_id=396565
<16> rnx: Access Violation, Segfault
<15> NitrotriggeR: the line ... not the type
