Comme l'a dit Renaud Dumont, je ferais quelque chose avec JointTrackingState
. Puisque vous utilisez les genoux, j'ai utilisé les variables leftknee
et rightknee
qui sont Joints
pour le faire. Voici le code, vous pouvez utiliser JointType.FootRight
et JointType.FootLeft
et le Hip
mais je vous laisse le choix.
static Skeleton first = new Skeleton();
Joint leftknee = first.Joints[JointType.KneeLeft];
Joint rightknee = first.Joints[JointType.KneeRight];
if ((leftknee.TrackingState == JointTrackingState.Inferred ||
leftknee.TrackingState == JointTrackingState.Tracked) &&
(rightknee.TrackingState == JointTrackingState.Tracked ||
rightknee.TrackingState == JointTrackingState.Inferred))
{
}
Ou alternativement, si vous voulez seulement qu'un genou soit suivi à la fois, ou les deux, vous pouvez faire ceci :
if ((leftknee.TrackingState == JointTrackingState.Inferred ||
leftknee.TrackingState == JointTrackingState.Tracked) &&
(rightknee.TrackingState == JointTrackingState.Tracked ||
rightknee.TrackingState == JointTrackingState.Inferred))
{
}
else if (leftknee.TrackingState == JointTrackingState.Inferred ||
leftknee.TrackingState == JointTrackingState.Tracked)
{
}
else if (rightknee.TrackingState == JointTrackingState.Inferred ||
rightknee.TrackingState == JointTrackingState.Tracked)
{
}
Pour info, la raison pour laquelle le Skeleton
est first
est static
c'est parce qu'alors il peut être utilisé dans la fabrication des joints
static Skeleton first;
Opposé à
Skeleton first;
Edit 1
J'en suis venu à la conclusion que c'est extrêmement Je pense que la méthode ci-dessus fonctionnera, mais je voulais juste inclure ce sur quoi je travaille au cas où vous seriez capable de trouver un moyen de le faire fonctionner. Quoi qu'il en soit, voici le code sur lequel je travaillais, qui est un autre class
qui est juste un autre SkeletalTrackingState
J'essayais de faire un Inferred
enum
en elle. Mais malheureusement enum
sont impossible à inherit
. Si vous trouvez quelque chose à cet effet qui fonctionne, je vous respecterai comme un programmeur supérieur à moi pour toujours ;). Sans plus attendre : Le site .dll

using IsInferred;

Bonne chance, j'espère que cela vous aidera à aller dans la bonne direction ou vous aidera tout court !
Mon code
Voici le code que vous m'avez demandé. Oui, il provient du Principes de base du suivi du squelette mais ce code était là et je ne voulais pas commencer un nouveau projet avec la plupart des mêmes choses. Bonne lecture !
