Witam. Ja niezbyt interesuję się muzyką, a rodzice proszą mnie o płytę z muzyką country. Polecilibyście kilka piosenek, żebym mógł uzbierać z 650 MB?

Coś tam wykombinowałem, i działa mniej więcej. Dzięki za pomoc. Jeszcze pobawię się z maską, bo mam wysokość 1 px i to powoduje, że nieraz hero przelatuje.

Parent ma mieć solid? E:Jak A nie ma solid to bohater przelatuje. Kombinowałem zmniejszać y w chwili gdy występuje kolizja na lini od bohatera do przestrzeni pod bohaterem, ale to prawie nic nie daje.

Witam, podchodzę do tego problemu już któryś raz, ale nie mogę go rozwiązać. Więc jest problem, ponieważ mam obiekt A, ma on robić za element terenu. Pod tym obiektem znajduje się zawsze inny element terenu B, ale zniszczalny. I teraz gdy element B zostanie zniszczony, element A ma spaść. Tylko, że może na swojej drodze spotkać element C, czyli obiekt, który jest głównym terenem. Niezniszczalny, nieprzesuwalny. I w tym problem, że element A musi być solid, bo bohater musi po nim chodzić. Wiadomo też, że nie powinno się dawać solid obiektowi w ruchu. Dodatkowo obiekt A powinien obrócić się w lewo, gdy jest podparty tylko z prawej strony i odwrotnie. mój kod jest taki: GML (step) n=0 while (n<129) { if !place_empty(x+lengthdir_x(n,image_angle) ,y+lengthdir_y(n,image_angle)+1) { ok=1 } n+=1 } if ok=0 image_angle+=1 while (n<256) { if !place_empty(x+lengthdir_x(n,image_angle) ,y+lengthdir_y(n,image_angle)+1) { ok=1 } n+=1 } if ok=0 image_angle-=1 GML (Begin step) a=0 GML (End step) if a=0 y+=2 GML (kolizja z C z B taka sama) move_contact_solid(270,vspeed) vspeed=0 a=1 Obiekt A niestety nie obraca się, i dopóki na początku gry nie spadnie, gra zamula. Prosiłbym o pomoc w zrozumieniu problemu.

Ale to głupio robią, że nie udostępniają możliwości robienia własnych gier. Na pewno tracą przez to dużo klientów.

Apple raczej nie. Macintosh to połączenie najgorszych cech Linuksa i windy. Drogi i nie ma na niego tylu programów co na windę. Linuks to nie taki zły pomysł, ale na pewno najpierw trzeba się trochę z nim nagimnastykować. Ja z wujkiem na bardzo starym kompie zainstalowaliśmy Linuksa i działa, nawet neta łapie. Ale kombinowaliśmy prawie rok.

U mnie infa jest jak W-F. Tok: -Siadam do kompa, włączam GMCLAN. -Koleżanka woła:Komp mi się wyłączył!!! Krzychu choć napraw! -Biegnę, włażę jej pod biurko i dociskam kable. -Wracam do kompa. -Pani każe włączyć jakiś program. -Rozlegają się krzyki:"Krzychu!!! Choć mi pomóż!" -Latam po klasie, włączam. -Coś mamy zrobić. -Krzyki:"Krzychu!!! Pomóż!" -Latam po klasie. -Pani mówi:"Nie rób wszystkiego za nich! Wytłumacz tylko jak mają zrobić. -Mówię im:Bardziej w lewo, jeszcze trochę, teraz trochę wyżej i klik lewym. Później praktycznie przyniosę byle co gościówie i mam 6.

Ale jak muszą udowodnić to bez sensu. Kupujesz sobie dysk zewnętrzny, na nim trzymasz piraty, codziennie czyścisz TEMP'a i nic Ci nie udowodnią, bo dysk możesz cały czas nosić przy sobie.

A oto mój instrument: Kto to mówił, że muszą być gitary. E:No może ja mam trochę tańszą wersję.

Mi się wydaje, że musisz udowodnić, że gra/program został zakupiony.

Szkoda, chciałem zrobić prezent kuzynowi. :( Ale jak się nie da to trudno.

Takie coś. http://t0.gstatic.com/images?q=tbn:ANd9GcR...ctemhsuGSZYIO-L

Witam. Mój kuzyn mieszka w Holandii i posiada konsolę Mi2. Tak naprawdę on ma prawie wszystko i nie wiem nigdy za bardzo co mogę mu dać na urodziny itp. Dlatego wymyśliłem sobie, że zrobię mu grę na tą konsolę. Niestety nie wiem jakiego języka się uczyć. Tak podejrzewam, że chyba Javy, bo wiele urządzeń mobilnych jej używa. Wie ktoś może od czego zacząć? Google mi nie podpowiedziało.

Kod napisać potrafię, gorzej z tym, żeby ustawić sobie środowisko. Instalowałem jakieś tam XAMMPy, Apachy i inne takie ale cały czas kicha. PHP w końcu zadziałało, ale MySQl nie, teraz wolę się Javy uczyć.

Ja w ogóle nie mogę nic zrobić w MySQL. Nie potrafię się nawet połączyć, a kombinowałem wiele razy.

Pewnie chciał poprawić humor Law'owi.

No tak, zapomniałem napisać. Chodzi o to, by zmienić tablicę ksiazki. E: Teraz mam kod: static String[] min=new String[11]; static String[] max={"","","","","","","","","","",""}; static String[][] cksiazki=new String[1000000][11]; public static void seg() { int czy; for(int a=0;a<iksiazki;a++) { czy=ksiazki[a][1].compareToIgnoreCase(max[1]); if (czy>0) { for(int b=0;b<11;b++) { max[b]=ksiazki[a][b]; max[b]+="z"; } } for(int b=0;b<10;b++) { min[b]=max[b]; } } for(int c=0;c<iksiazki;c++) { for(int a=0;a<iksiazki;a++) { if (ksiazki[a][1]!=null) { czy=ksiazki[a][1].compareToIgnoreCase(min[1]); if (czy<0) { for(int b=0;b<11;b++) { min[b]=ksiazki[a][b]; ksiazki[a][b]=null; } } if (czy==0) { czy=ksiazki[a][0].compareToIgnoreCase(min[0]); if (czy<0) { for(int b=0;b<11;b++) { min[b]=ksiazki[a][b]; ksiazki[a][b]=null; } } if (czy==0) { czy=ksiazki[a][2].compareToIgnoreCase(min[2]); if (czy<0) { for(int b=0;b<11;b++) { min[b]=ksiazki[a][b]; ksiazki[a][b]=null; } } if (czy==0) { czy=ksiazki[a][3].compareToIgnoreCase(min[3]); if (czy<0) { for(int b=0;b<11;b++) { min[b]=ksiazki[a][b]; ksiazki[a][b]=null; } } if (czy==0) { czy=ksiazki[a][5].compareToIgnoreCase(min[5]); if (czy<0) { for(int b=0;b<11;b++) { min[b]=ksiazki[a][b]; ksiazki[a][b]=null; } } } } } } } } for(int d=0;d<11;d++) { cksiazki[c][d]=min[d]; min[d]=max[d]; } } I prawie działa, tylko nieraz "zapomina" niektórych pozycji i do ostatniej pozycji zawsze dodaje "z". Wiecie dlaczego?

Witam, poprzednie problemy rozwiązane, teraz mam nowy. Mam taki kod metody: public static void seg() { int czy; for(int a=0;a<iksiazki;a++) { czy=ksiazki[a][1].compareTo(max[1]); if (czy>0) { for(int b=0;b<10;b++) { max[b]=ksiazki[a][b]; max[b]+="zzz"; } } for(int b=0;b<10;b++) { min[b]=max[b]; } } for(int c=0;c<iksiazki;c++) { for(int a=0;a<iksiazki;a++) { if (ksiazki[a][1]!=null) { czy=ksiazki[a][1].compareTo(min[1]); if (czy<0) { for(int b=0;b<10;b++) { min[b]=ksiazki[a][b]; ksiazki[a][b]=null; } break; } if (czy==0) { czy=ksiazki[a][0].compareTo(min[0]); if (czy<0) { for(int b=0;b<10;b++) { min[b]=ksiazki[a][b]; ksiazki[a][b]=null; } break; } if (czy==0) { czy=ksiazki[a][2].compareTo(min[2]); if (czy<0) { for(int b=0;b<10;b++) { min[b]=ksiazki[a][b]; ksiazki[a][b]=null; } break; } if (czy==0) { czy=ksiazki[a][3].compareTo(min[3]); if (czy<0) { for(int b=0;b<10;b++) { min[b]=ksiazki[a][b]; ksiazki[a][b]=null; } break; } if (czy==0) { czy=ksiazki[a][5].compareTo(min[5]); if (czy<0) { for(int b=0;b<10;b++) { min[b]=ksiazki[a][b]; ksiazki[a][b]=null; } break; } } } } } } } for(int d=0;d<10;d++) { ksiazki[c][d]=min[d]; } } } Niestety w wyniku mam tablicę wypełnioną 1 wartością. O co chodzi?

write, tworzyłem obiekty fileWriter itd i nie było problemu. Jak to naprawić? E: I dlaczego występują te błędy? Jak unikać ich w przyszłości. E2: Pliki się tworzą, ale puste.

Ja kiedyś próbowałem napisać fizykę spadającego bloku, ale to nie takie proste. Mam jednak pomysł jak obliczyć nachylenie, sprawdzasz, czy linia, o długości ok 4 px. i środku w miejscu obiektu koliduje z czymś. Jeśli koliduje zmienia nachylenie i w końcu jeśli nie ma kolizji masz nachylenie.

Witam, ma pytanie. Jak dodać menu kontekstowe do ramki w wxWidget? Mam taki kod: WxPopupMenu1 = new wxMenu(wxT(""));WxPopupMenu1->Append(ID_MNU_KARTONZPAPIERU_1003, wxT("Karton z papieru"), wxT(""), wxITEM_NORMAL); WxPopupMenu1->Append(ID_MNU_KARTONZTEKTURY_1004, wxT("Karton z tektury"), wxT(""), wxITEM_NORMAL); WxPopupMenu1->Append(ID_MNU_KARTONZSRAJTA_MY_1005, wxT("Karton z srajtaśmy"), wxT(""), wxITEM_NORMAL); WxPopupMenu1->Append(ID_MNU_KARTONZSAMEGOKLEJU_1007, wxT("Karton z samego kleju"), wxT(""), wxITEM_NORMAL); WxPopupMenu1->Append(ID_MNU_ODLEWKARTONUZGIPSU_1006, wxT("Odlew kartonu z gipsu"), wxT(""), wxITEM_NORMAL); Tylko nie wiem, jaką funkcją mam dodać to do ramki programu jako menu kontekstowe. pomoże ktoś?

Albo wybrać jeden z tych obiektów, ustawić najniższy depth i w nim w drawie dać to co dał Muczek, obawiam się tylko, że nastąpi pływanie.

Chyba na miesiąc dam sobie spokój z Javą, mój internet jest naprawdę do kitu, wywaliło mi, że mam czekać cały dzień. Ale dzięki za podpowiedź, przynajmniej będę wiedział jak naprawić problem. E:Ściągnąłem w końcu. mam teraz jeszcze jedno pytanie, jak sprawdzić wartość JTree, próbowałem już getLeadSelecetionRow, ale działa z opóźnieniem.

Chodzi o to, że postanowiłem się nauczyć języka Java, i ściągnąłem sobie Netbeans. Instaluje i wyskakuje, że nie ma JDK, chociaż mam zainstalowaną Jawę na kompie. To odznaczyłem kilka pozycji do zainstalowania i w końcu ruszyło, ale nie mogę napisać żadnego programu, nie mogę stworzyć żadnego projektu, bo cały czas brak tych komponentów. Ale nie mogę zainstalować ich, bo coś nie tak jest z JDK. Kurcze, ściągałem to IDE 8h. i szkoda mi stracić tyle czasu. Nawet nie wiem skąd wziąć to JDK. Pomoże mi ktoś zaopatrzyć się w działające IDE, ściągając jak najmniej? Bardzo mi na tym zależy, bo mój internet jest bardzo wolny.

Chodzi o to, że teraz mało jest takich gier, przyjaznych, miłych, teraz większość jest takich, że w trakcie rozgrywki ekran jest prawie cały czarny, denerwująca muzyka itd.
