Re: Preparing Bullet 2.83 and 3.x at github, clone an test!

Is it possible to have an approximate date for Bullet 3 ?
Kinematic character controller will works correctly using capsule on Bullet 3 ?
Bullet 3 will be as stable as PhysX ?

Bullet 3

Hi,
We are on the second month of 2014 and I would know if a release date is know for Bullet 3 ?
I would know if Bullet 3 is more stable than Bullet 2, for example Kinematic Character Controller.
Does it works like Bullet 2 or it's completly different ?
Thanks

Issue Found : btkinematiccharactercontroller

Hi all,
I've found an issue when I use btkinematiccharactercontroller and a Capsule.
If the start transform is inside the btTriangleMeshShape, I got a crash of bullet physics.
That should not happen I guess, the only way is to set the start transform a bit upper.

btkinematiccharactercontroller capsule offset

Hi all,
using btkinematiccharactercontroller you need to set to it a btConvexShape but I need an offset on the capsule to have it good.
The offset needs to be the half of the height on the y, because my character mesh has foot at 0.
There is a way to achieve that ?
Thanks

Big value crash

Hi all, When using bullet with big values (using units and not meters, so 1.75 is like 50), I got a crash when enter in collision using a capsule. It's funny because I don't have a crash using a sphere as collision shape. I got very bad result too on the update of the physic, maybe Bullet become mad...

Kinematic Character Controller

Hi,
I would to know the advance of the kinematic character controller in Bullet Physics.
is it still experimental ?

Thanks

Scaling the world And Stairs

Hi, I'm using bullet on my game, all is working fine at this moment. My first question is about the scaling.I must scale my objet 0.02f on each axis to not have slow motion. Do It has one way to change the scaling ? My second question is about character controller. I have done a character controller...

Using Bullet for collision in ParticleSystem

Hi,
currently working on a particle system, i would use bullet to manage collision.
What is the best solution to do this ?
Is-it correct to use box shape for each particle ?

Thanks

Re: Can't Move rigid body / Apply force

Can't Move rigid body / Apply force

Hi, I have bullet correctly initialized and have 200 sphere who collide, all works fine but when i want apply force to a rigid body he doesn't do anything or if i use translate( vec3 ) on a simple sphere on a plane, he moves but don't update his position with gravity. Do I have forget something ? Th...

Dynamica CompoundShape / multiSphereShape

Hi,
I would have informations about implementation of compound shape into dynamica plugin and if multiShapeSphere will be implemented too, because rigid body sphere shape don't allow to use non-uniform scalling factor.

Thanks to answer

Re: Compound collision shape using .bullet binary file

Ok, i have a solution (don't have try it for now) :
Using btBulletWorldImporter and set a NULL pointer at the constructor and get the collision list.

btCompoundShape, sphere shape scaling.

Hi,
Using a btCompoundShape to set a list of collision shape, btSphereShape is scaled when
SetLocalScaling is used or it need to use a btMultiSphereShape with just 1 sphere ?

Thanks to answer

Compound collision shape using .bullet binary file

Hi, I have used maya dynamica plugin, all working good when a play animation, this plugin is good ! My question is simple, when I export to .bullet binary file, i suppose he exports all structure data with name all that. Is it possible to import this .bullet file just for one objet into a btCompound...
