Et step videre: Spil

* Snake Klonen har jeg lavet i konsollen. :)

Der er en del artikler om spil her:
http://www.gamedev.net/

Har selv fået anbefalet sdl af en herinde. Det er forholdsvis let at gå til.

bertelbrander >> Har kigget på siden, men syntes kun jeg kan finde artikler om vilde 3d spil for folk der allerede kender til det grundlæggende, søger en slags "starter" artikel.

thomas_nj >> sdl? lyder spændende forklare nærmere... :)

Jeg har fundet den fedeste guide: http://www.gamedev.net/reference/design/features/makegames/

Men har ingen idé om hvordan jeg får lavet det.
win32 api? og hvordan?

Det er jo næsten som mit snake spil bortset fra at det kører på en win32 platform istedet for en dos promt.

SDL er et platform uafhængigt api som bl.a. wrapper opengl til at tegne grafik på din monitor. Men det osse bruges til til at fange input fra dit keyboard/mus.

Jeg vil nok hellerer anbefale clanlib eller allegro til dig fordi det er nemmerer at gå til når man skal tegne i 2d.

Xafion:
Hvis du virkelig vil lære noget så bør du nok investerer nogen penge i et par bøger game programming gems serien er et must.

Du kan læse om sdl her: http://www.libsdl.org/index.php

  Du kan lege lidt med det med denneher tutorial. Den er meget overfladisk, men den giver dig en masse kode du kan sidde og lege med.

mathiash >> Jeg må vel ikke se koden til dit snakespil vel? Lavede nemlig selv et for et stykke tid siden, men vil gerne se hvordan andre har gjort.

Måske ikke den flotteste kode men du må da godt få den, jeg kigger lige på linksne lidt senere.

Map delen, er "stjålet" fra Midgårds da jeg syntes det var så genialt! :)

Kommer her. Og mange tak fordi jeg måtte se din kode
