Attraction to planes

Postby immibis » Sat Oct 17, 2009 10:32 am

Objects with an attraction value which is not 0 are not attracted to planes. However, if the plane's attraction is not 0 then objects are attracted to it.

Another attraction-related bug is that attraction is towards the center of the object, where I think it should be (or there should be an option for it to be) in the direction of the normal at the closest point.

The attraction towards the center is not a bug (I'm pretty sure it at the center of gravity though) In most practical things (like a circle) this isn't a probleam but in complex polygons this can become an issue.

And I'm having trouble replicating this bug (0 percent success)

1. Make a plane facing sideways
2. Make a circle, or another object
3. Set the plane's attraction to 100
4. Run the scene
5. Notice the object falls normally and isn't attracted to the plane.

Objects aren't attracted to planes they're not meant to be, that would be extremely annoying and ruin almost every scene with attraction in it.
Planes can attract/repel objects to them selves but not the other way around.

Isn't the power of the attraction affected by the weight/whatever of the object? Then what kind of attraction would an infinite plane produce?

I would expect it to ignore the plane's weight and use the object's weight instead, probably. Although if this was fixed it would probably break existing scenes.
