Title: Roche Limit/ Explode Bug
Post by: vh on June 01, 2011, 04:43:38 PM
Hi, i was trying to "simulate" the roche limit by seperating an object into 13 sections by exploding at 0m/s I set the collision mode to bounce, so that i would have 13 sections that could be pulled apart by Jupiter's gravity. However, when i blow up any object (at 0m/s or not) inside the roche limit, it just immediately freezes. According to the interface, it's still traveling 36 m/s but it is completely still on screen. When i attempt the same with an object outside of Jupiter's gravity, it suddenly flies off. I don't understand, I didn't add or subtract mass. Didn't change speed.

I doubt you're doing anything wrong. This is a likely a bug in the way bounce mode is implemented. If you move the moon further away from Jupiter before exploding it, you might have better success.

Well i'm trying to simulate the roche limit by turning a moon into a couple of pieces to see if Jupiter will rip it apart. Is there another way?

Roche Limit effects aren't implemented yet.

if I attempt to spawn a object inside, or partially inside, another object with collide mode on I get a crash.  perhaps something similar is occuring here?  maybe a small explosion velocity will help.

This is my fault. This shouldn't cause a crash.

try turning it off of bounce mode for the simulation first
