J'essaye de rendre le texte à l'écran mais continue à recevoir des symboles de poubelle et je ne peux pas comprendre ce qui est si différent dans mon approche.Pourquoi mon char [] stocke-t-il des ordures?
Ce code fonctionne dans mon programme principal:
char vectorText[80];
sprintf(vectorText, "vector%i = [%f, %f, %f]", 1, vector[0]->x, vector[0]->y, vector[0]->z);
char* newText = vectorText;
Text* finalText = NULL;
finalText = new Text(22, 0, 400, false, newText, 0.0f, 0.0f, 1024.0f, 200.0f);
scene.AddText(finalText);
Cependant, dès que je le place dans une fonction, il commence crachant des ordures. Je sais que c'est le vecteurcarTexte [] parce que quand je le contourne, je reçois du texte.
char vectorText[80] = "This prints garbage";
//sprintf(vectorText, "vector%i = [%f, %f, %f]", 1, vector[0]->x, vector[0]->y, vector[0]->z);
//char* newText = vectorText;
Text* finalText = NULL;
finalText = new Text(22, 0, 400, false, vectorText, 0.0f, 0.0f, 1024.0f, 200.0f);
scene.AddText(finalText);
Le bas fonctionne, mais évidemment, il ne va pas me donner ce dont j'ai besoin.
//char vectorText[80];
//sprintf(vectorText, "vector%i = [%f, %f, %f]", 1, vector[0]->x, vector[0]->y, vector[0]->z);
char* newText = "Text will work from here";
Text* finalText = NULL;
finalText = new Text(22, 0, 400, false, newText, 0.0f, 0.0f, 1024.0f, 200.0f);
scene.AddText(finalText);
Toute aide serait bon, je suis tout à fait à une perte :(
