Ignoring grouped objects
-
So here I am making something with sketchy physics and I cant figure out how to make something be ignored (so that it has no weight and does not collide) while grouped to some active things , not even a simple edge. This seems very weird but when I have several grouped objects and then add a simple edge to them, the edge passes straight through stuff but has some incredible weight for something mathematically thin! even if I try to make the only group it is in ignored.

I am not sure I understand. Could you post an example?

Here's an example. What I want to happen is the edge (I want it weightless) gets whipped around by the box, not visa-versa.

Ah, you need to make the box and the line 2 separate groups. Make the line its own group, flag it as ignore and then group with the box.

That does make the edge fly straight through stuff, but it still outweighs the box. I think the problem might be that when I group them, the group that they are in has weight to it even though it has no geometry directly inside it. If this is the problem I have no idea how to fix it.

Congratulations, You found a bug. It looks like the center of gravity is at the center of the object even tho part of it is set to ignore. I am surprised no one has found this before. Ill fix in the next release.

Crazy, I'm surprised also. Thanks!
