Physics with bitmap images?

[benecosse]

In AS pro 7, does the new Physics engine work with bitmaps or is it just vectors?

Just tried it and no, not with just a bitmap layer.
You'll have to bind it to bones, but then it won't react according to the shape of the bitmap, just the bone.

I don't have ASP7 but physics was probably implemented without a limitation on opacity, so try adding a vector layer, tracing around your bitmap, and then setting the opacity to 0.

You can use an image texture in a vector shape and then, yes, images will work with physics.

I've been playing with this a bit over the weekend.

I wanted to take an illustration of a 50lb weight, and drop it on a see-saw type device with boxes on the other end. Now I could trace it, but I would looses the textures and the look I wanted.

I tried image textures, but had trouble lineing the up correctly and was unable to find a way to adjust the points with out distorting the contained texture.

What I ended up doing is, binding an image layer to a bone, and then binding a vector layer to that same bone as a bounding box, in ruffly the shape of my illustration. Then I simply turn off the bouding boxes visablity. Tada I could have my ACME style 50lb wieght drop on the See-saw, catapulting whatever I placed on the other end.

It's sort of a variation on the bonding box method used in games.

I haven't done much testing yet, but it appears to work best, if the bounding bone is small, pointing strait up and placed at the center of gravity of the bonding box.

I think that Member States have the legal right to cover your ass and tell you to ensure the authorization obtained. If you find a license that says its OK to share with the entire font as a bitmap and you are good.
