Here's a more simple way: dl.dropbox.com/u/52670878/CheckValues.cap

Here you go: dl.dropbox.com/u/52670878/example.cap

Make the objects herosprite and hero non-global, and copy>paste them in the other layout. That worked for me.

If it's colliding with a wall set the ship's angle to 2*wall's angle - ship's angle.

here's a picture explaining the maths:

If it's colliding with an asteroid, you can first get the b angle, by using the system angle between points expression.

I'm not sure if that's the kind of "bounce" you wanted though.

Sometimes when physics objects collide at low speed they don't bounce, but stick with each other, no matter how much their elasticity or linear damping is.I'm not sure if this is a bug, or something i don't understand yet.

Here's what i'm talking about: dl.dropbox.com/u/52670878/bug.cap

How can i fix this, so that the objects always bounce off, no matter how slow they move?

Aha it seems something is wrong with the bounce action.It picks all instances of the sprite instead of one.

The best workaround i can think of.Let me know if you can't figure out how it works.

Aah ok.Thanks again for the help rojohound, you're a pro.

Have you tried adding loop for each Family Member on top of all that?

And if that doesn't work you could try on collision with family member instead of overlaps family member.

That's an excellent example(idea) rojohound,thank you very much. One last question: how can I load the canvas' frame into a sprite object frame?

I don't know python, so i'll try to use the custom movement behavior to recreate the physics behavior somehow, as a workaround for the collision masks.

Thanks for replying rojohound but for those tutorials the problem is that i don't have lines intersecting, but an object and a line...

How can i use the canvas plugin to make two different objects? I don't see a way to load animation frame from canvas.

No one? Ah, well i guess i should be proud i discovered something that's impossible to do in construct...

Isn't random(250)+random(250) the same as random(500), lol??
