Salut Germain,

Ca fait un bail (je n’ai pas ouvert msn depuis 1 an à peu près…

Tu bosses où en ce moment ?
Moi, je suis chez Bouygues Tel (Applis sur SetTopBox)

Très intéressant ces travaux sur Box2D !

Passe le bonjour au collègue edocoien à l’occaz

ahhh, good find on the RayCast stuff…

My implementation works similarly, but is nowhere near as efficient…

I think it’s a slight shame that the box2d manual is so basic… (and doesn’t include some of the great additions.)

@charlie I found informations on RayCast

And AS3 application in : http://personal.boristhebrave.com/project/box2d-raycasts

Tanks for your interesting comment !

Il will add notes and schema in this post to explain difficulties to render a good explosion (Point of application, center mass, density 0 bodies …)

Following on from the previous message it’s possible to use b2Segment to do a “ray-trace” from the origin of the explosion.
From that it’s possible to determine the density of any shape in between the the explosion and the object being moved…

That’s very good, I was just about to start working on something very similar…
But, can you adapt it so that the force doesn’t pass through objects which have density = 0??
