It should be possible, as long as I can find which velocities/forces/torques? are needed to make the object behave the same as it did before saving its values. Now I only have position rotation saving, though it should be fine for a level editor, it might not be enough if I plan in game level saving...

Hey dphil, wow, thank you very much! It works like a charm... You're right, I know the body->activate() method, but I've no idea what it's actually doing and why I sometimes need it and sometimes don't need it. You need them when rigid bodies get deactivated (they get in some sort of sleep state, w...

How do I get all velocities applied to rigid body? I need them all so I could save them to xml and load them back when I need them. I know theres a serializer, but it won't do what I need. What data do I need to get in order to get the body move the same as before saving to xml? I tried just getting...

I think I found whats causing it, though I don't really understand why its causing it.. What I had before in my scene was one box rigid body, two sphere rigid bodies and one trimesh rigid body. Once I removed trimesh rigid body and tested the app it didn't crash as much as I've tried. Do I need to p...

:? Hm, perhaps you could make sure you are cleaning up your memory in the right order. Take a look at the Hello World example as a guide. Yeah, still the same behaviuor: if(m_world) delete m_world; if(m_solver) delete m_solver; if(m_collisionConfiguration) delete m_collisionConfiguration; if(m_disp...

bump. I need to know whats causing this, because I can't continue working on my project :oops: The only problem now is that my application sometimes crashes(segfaults) at exit while deleting btSoftBodyRigidBodyCollisionConfiguration. Maybe its a bug with 2.78 bullet? Here's my constructor,destructor...

whoa, nice spam bot

How do I actually use the btSoftBodyWorldInfo? What do I need to do with it when I Initialize my physics, and when I destroy my physics world? I can't really tell whats needed to be done with it from SoftBody samples as it is poorly commented, and api doesn't have comments at all on this. EDIT: Hm, ...

My app is crashing at application exit, and it seems to be something with bullet because the last calls on call stack are made by bullet.


I'm using bullet 2.78, on linux.

Any hints on what could be wrong are more than welcome

do you really need the height, or you just need a way to calculate damage?

If you need to calculate damage you should get the velocity of impact.

If you need the height of the fall I think you should track it manually.

just search the forum, I have seen some similar threads that were answered.

Blender? I don't know what the blender is. Can you explain to me? I like to learn bullet physics engine and how to use the engine. but I cannot understand it by myself. I hope there is some teacher or guider for me. You can't understand it because: 1) You haven't learnt how things in c++(or any oth...

Don't have the code at the moment, but it's a normal kinematic body (look at the wiki for a hint or two how they work with motionstates, which will also answer your question about how to set their position correctly), and a "default" sphere, default gravity. Okay I'll have a look when I g...
