Scusate se vi faccio troppe domande ma sono ancora alle prime armi e devo imparare molte cose xD
Ho trovato il nuovo tutorial(quello più aggiornato):
http://lazyfoo.net/tutorials/SDL/01_hello_SDL/index2.php
Sembrerebbe più affidabile, ma devo ancora provarlo. Per vedere se funziona(velocemente) potrei fare una prova copiando e incollando tutto? Anche se sospetto che mi apra comunque una finestra nera vuota o con "premere un tasto per continuare", quella dell'hello world...
Comunque, in vari comandi ho notato che c'è la parola NULL; , cosa significa? Devo aggiungere qualcosa al posto di null?
_______________________
Ecco, ho scaricato il file, copiato su code::blocks e:
Con il debugger mi apre una scheda nera(come quella del cmd o dell'hello qorld) vuota;
con il build and run mi apre la stessa scheda con scritto il tempo di esecuzione e premere un tasto per continuare ;(
