Je travaille sur un moteur graphique avec DirectX. J'ai simplifié l'un de mes func comme celui-ci (parce qu'il a la même question):VS 2010 Débogage de variable locale C++
void foo(int p,int q){
if(!p){
int a=0;
a=4;
}else{
int a=0;
a=5;
}
if(p==1){
if(q==1){
float opacity=0;
}
}
}
int main(){
foo(1,2);
return 0;
}
si je l'appelle foo (1,2), je ne peux pas les valeurs de vue d'un bloc dans le reste dans VS panneau de débogage, mais quand J'appelle foo (0,2) je peux voir les valeurs d'un dans si block.Il montre le symbole 'a' non trouvé bla bla ... Et quand j'ai changé "float opacity = 0;" "float opacity" ça marche bien et je peux le déboguer.
je groupe les objets, les mailles et les matériaux en fonction de leur properties.Here est ma fonction originale:

Je n'ai pas vu 'VOID' depuis des décennies. Toutes nos félicitations. –
Pas étonnant que vous ayez passé le débogage des heures entières, s'il s'agit d'une version simplifiée de votre fonction –
Hmm ... cette fonction exacte montrait toutes les variables attendues sous mon débogueur VS2010. Pourriez-vous être plus précis quant à ce que vous avez réellement fait? –
