Dobrý den, začal jsem psát jednoduchý tetris v OpenGL, ale mám jeden problém. Nedaří se mi vymyslet, jak zabránit tomu, aby jednotlivé kostky padaly přes sebe. Potřeboval bych udělat, aby se, když kostka dopadne, stala "staticky pevnou" a ostatní nemohli padat přes ní a překrývat ji. Zkoušel jsem to vymyslet pomocí souřadnic poloh kostek, ale je to dost složité. Kdyby na to existoval nějaký příkaz,dost by mi to usnadnilo práci. Zde je zroják a bitmapy: http://uloz.to/668830/tetris.rar

PosthunterJá jsme tetris řešil tak, že jsme měl 2D pole char, 0 - prázdné, 1 - červená kostička, 2 žlutá apodob... a potom už toto rozhodování bylo jenoduché
to pole zni jako dobry napad ... proste musis otestovat vsechny casti toho prvku co pada jestli ma jeste kam padat.. .pak ho jen zapsat do toho pole... zajimavejsi je pak treba likvidovani radek ale to muzes jen prekopirovat o jednu niz
To Tom9k : Bohužel už nemám - padl jako oběť mé nepozornosti při reinstalaci winů...
JInak měl jsem pole hrací plochy a kostičku jsem reprezentoval zase jako pole. A při změně souřadnic kostičky jsem si uložil kopii souřadnic, potom jsem testoval kolizi - postupně jsem procházel po řádcích kostičku, pokud v buňce byla nenulová hodnota, otestoval jsem buňku v hrací ploše se souřadnicemi [x testovane buňky v kostce + x kostky; y testovane buňky v kostce + y kostky] a když byla nenulová, věděl jsme , že je kolize; potom jsme otestoval, zda-li vznikla změnou x, nebo y. Pokud y, tak jsme kostičku natrvalo nakopíroval do plochy, pokud x, tak jsem použil staré souřadnice.
Takže: tetris už je skoro hotovej, ale je tu jeden velkej problém- totiž,když se program spustí, začne narůstat využití paměti, a to dost dramaticky, a pořás se to zvyšuje. Mohl byste mi někdo poradit? Potřeboval bych nějak uvolňovat paměť za běhu programu, ale nevim kde. Zdroják :

}To Tom9k : no kdybys použil debuger tak problem vyřešíš za 5 minut. Jinak prohlídl jsem to jen tak letmo, ale to vytvareni fontu nemuzes delat kazdy frame. Vytvaret font musis pri nacitani(stejne tam jak nacitas textury), kdyz ho budes vytvaret kazdy frame tak to urcite bude pomaly a hlavne neefektivni. Jinak ten font musis taky smazat kdyz ho vytvoris, zkus to prekopat a radsi si jeste jednou procti ty nehe tutorialy.
Tak mozna ne,ja ten kod vazne cely nestudoval,ale podle toho co rika eMan,tak ma pravdu.Pokud pokazde vytvaris fonty,tak to muze neumerne zatezovat ramku.Musis si vytvorit pole znaku a ty vykreslovat tak, jak je v nehe tutorialech.
To Master : Já totiž předtím myslel, že se ty fonty musí znovu vykreslovat při každém cyklu, přitom stačí jen jednou a v okně zůstanou. Akorát, když chci použít celkem tři rozdílné fonty, tak nastavím parametry (velikost, typ písma) a musím pokaždé zavolat funkci BuildFont(), nebo je možné mít uloženo více fontů zároveň?
Stálý členNevim co myslíš tím cyklem, ale ty fonty musis vykreslovat v kazdem framu(u tebe volani fce DrawGLScene), pokud teda mazes buffer( glClear... ). Nejednodusi bude asi si ty fonty predvytvorit(pri inicializaci) a potom jenom pouzivat jednotlive fonty.
Btw. radši si to nastuduj pořádně, takhle to vypadá jako bys splácal několik nehe zdrojaku do sebe a prava ruka nevi co dela leva.
Návštěvník:)) Vykreslovat se to musí (text, který chceš vypsat daným fontem). Ale neměl bys je opakovaně vytvářet, protože bys měl v paměti kupu stejných dat, což moc moudré není.
Co ty potřebuješ, je mít několik objektů té struktury ukládající font, na začátku programu si (3) potřebné fonty jednou vytvořit a pak při vykreslování dávat font jako parametr nějaké tvojí funkci zobrazující texty.
Jak pise Huge,na zacatku si je inicializujes a pak je nechavas nejakou funkci vykreslit.Samotny princip spociva v tom,ze se vytvori tzv. "Display list".Tato technologie slouzi k uchovani objektu,u kterych se mnohonasobne vytvari instance.Do tohoto display listu se ulozi ctverecky z nahrane bitmapy fontu.Ty se pak zobrazuji tak,ze se nevytvari neustale instance,ale ze se veme jejich adresa v pameti a pouzije se pro vykresleni.
Tady mas kousek zdrojaku,ktery sem pouzival pro vykreslovani:
GLvoid Font::InitFont() // Build Our Font Display List
{
/**
* Inicializace fontu.Proste texturu nakouskuje a ulozi si to do display listu.
* Musi se zavolat az PO zavolani metody LoadFontFromTexture.
*/
float cx; // Holds Our X Character Coord
float cy; // Holds Our Y Character Coord
base=glGenLists(256); // Creating 256 Display Lists
glBindTexture(GL_TEXTURE_2D, fontTexture[0]); // Select Our Font Texture
for (loop=0; loop<256; loop++) // Loop Through All 256 Lists
{
cx=float(loop%16)/16.0f; // X Position Of Current Character
cy=float(loop/16)/16.0f; // Y Position Of Current Character
glNewList(base+loop,GL_COMPILE); // Start Building A List
glBegin(GL_QUADS); // Use A Quad For Each Character
glTexCoord2f(cx,1-cy-0.0625f); // Texture Coord (Bottom Left)
glVertex2i(0,0); // Vertex Coord (Bottom Left)
glTexCoord2f(cx+0.0625f,1-cy-0.0625f); // Texture Coord (Bottom Right)
glVertex2i(16,0); // Vertex Coord (Bottom Right)
glTexCoord2f(cx+0.0625f,1-cy); // Texture Coord (Top Right)
glVertex2i(16,16); // Vertex Coord (Top Right)
glTexCoord2f(cx,1-cy); // Texture Coord (Top Left)
glVertex2i(0,16); // Vertex Coord (Top Left)
glEnd(); // Done Building Our Quad (Character)
glTranslated(10,0,0); // Move To The Right Of The Character
glEndList(); // Done Building The Display List
} // Loop Until All 256 Are Built
}
GLvoid Font::ReleaseFont() // Delete The Font From Memory
{
glDeleteLists(base,256); // Delete All 256 Display Lists
}
GLvoid Font::DrawText(int set,const char *string,GLdouble scale) // Where The Printing Happens
{
/**
* Vykresluje font ve 3d souradnicich.Mezitim meni i velikost.
*/
if (set>1)
{
set=1;
}
glBindTexture(GL_TEXTURE_2D, fontTexture[0]); // Select Our Font Texture
glEnable(GL_BLEND);
glDisable(GL_LIGHTING);
glScaled(scale,scale,scale);
glListBase(base-32+(128*set)); // Choose The Font Set (0 or 1)
glColor3f(1.0f,1.0f,1.0f);
glCallLists(strlen(string),GL_BYTE,string); // Write The Text To The Screen
glEnable(GL_LIGHTING);
glDisable(GL_BLEND);
}
je to jen vynatek,ale mel by poslouzit ke spravenem cili :)
