Jeg har lavet en funktion glPrintBox, som skulle tegne en boks til skærmen, hvorpå der står noget som man selv har valgt.
Jeg har bare det problem at den kun skriver den første boks til skærmen, og undlader den anden (eller der kommer i alt fald ikke noget).
så jeg vil meget gerne vide hvad min fejl er, og hvordan den kan rettes?
Jeg har indsat koden herunder:
ps. den åbner en fil kaldet data.txt på den placering exe-filen ligger, hvori der er to linier, med to ord i hver, hvoraf den gerne skulle skrive det første ord fra hver af sætningerne i en boks.
