Solved, after the contact test I was deleting the object incorrectly which caused an unexpected situation.

No exception occurs, it just say that "The application has stopped working".

Hello, I have tried using contactTest with collision objects and it didn't work as expected, it crashed my application on the second call whereas contactTest worked well with rigid bodies. Object Creation: btCollisionObject* col = new btCollisionObject(); col->setCollisionShape(shape); col->setColli...

Solved it, there was a mistake on my side related with structs.

Hello, I have been trying deleting rigid bodies during simulation and it always crashes my application. I followed the below code. void destroyBodies(btDiscreteDynamicsWorld* dynamicsWorld, btRigidBody* body) { dynamicsWorld->removeRigidBody(body); delete body->getMotionState(); delete body; }

trying

Code: Select all

btGhostObject* test()
{
	btGhostObject* ob = new btGhostObject();
	return ob;
}

error C2143: syntax error : missing ';' before '*'

trying

Fixed it.

For Deactivation:

Code: Select all

object->setActivationState(DISABLE_SIMULATION);

For Activation:

Code: Select all

object->forceActivationState(DISABLE_DEACTIVATION);

Hello,

When I try to activate a deactivated body it still remains deactivated.

For deactivation:

Code: Select all

object->setActivationState(DISABLE_SIMULATION);

For activation:

Code: Select all

object->activate();

Hello,

As far as I know, Bullet3 resolves collision and handle rigid body dynamics through GPUs. My question is:

Is bullet3 fit for online games (server-sided) ?

I am asking this because some of the hosting services only care about RAMs and CPUs instead of GPUs.

Thank you

Hello,

My question is, How to get the vertices(or transformed vertices) of a compound shape ?

I have searched a lot but no luck.

Thank you.

I do not want them to stop while in air. By the way, can they be stable on land if friction is applied to them.

I set the linear and angular velocity to 0.0 and they are working as I wanted them to work. Thank you.
I'll look into the flags.

Use btRigidBody::setSleepingThresholds() to set the linear and angular velocity thresholds for "slow". Thank you for your reply. What values are fit for linear and angular velocities? EDIT: What is the difference between world gravity and rigid body gravity ? Does rigidbody gravity gets a...

By the way, I have this problem too, after removing the body I can still get its position and rotation.

Hello Bullet Physics Community, I am new to Bullet and as well as this forum, too. I am facing a major problem with the behaviour of spheres when colliding with each other in mid air. There are 2 spheres with their own gravity and restitution. When they fall, Sphere 1 collides with Sphere 2 and Sphe...
