InspectorWidget could be more helpful ...

Ok, je suis toujours dans les ajustements supposés permettre à Bilou de soulever un taille-crayon dans un empilement. DDD, cybook, tout le monde y passe ... j'aurais bien aimé avoir un peu plus progressé sur l'Inspector Widget pour me simplifier la tâche, mais il faut faire avec ...

Après avoir envisagé la possibilité d'envoyer un message "à tous les objets qui me sont attachés", j'opte pour une approche plus pragmatique: une variable de la plate-forme que les objets transportés peuvent tester via leur contrôleur (on écrira donc onpath(when w7.1)) pour demander un avertissement si la 7eme variable de la plate-forme voit son bit 0 retomber à 0.

At last, Bilou can pick up any blador even when they're stacked up. One glitch fixed. I hope the same technique will allow me to have Bilou's carrying/non-carrying state more coherent. What technique ? Well, at first I thought collisions would be suitable to notify that one can no longer stand on a platform. E.g. when the platform fades into the background, I'd have a state with a collision area triggering a $STAND->$FALL (Detach) transition. But that's not working properly, because gobs might get collisions from another object that the one they're attached to. Tweaking areas so that the collision is properly received by all the gobs in all their states also turns into a sort of nightmare. 
Instead, I updated 'onpath' controller so that it optionally polls one of the target's variable and raise an event when this variable states "I'm no longer a solid platform, go away." That was the least resistance path. Plus, the polling is virtually free since we had to check that target for presence, position and speed anyway.

What about inspector widget and the picture ? well, it's an additional todo list to remember everything InspectorWidget should have been able to do to ease the (completed) debugging session.

On dirait bien que le problème est maintenant résolu. Glitch suivant: les mains de Bilou qui disparaissent dans certaines conditions (lancer un taille-crayon près d'un taille-crayon isolé, p.ex).
