A sandbox game created from Bullet physics - Dapenter

Hi guys, This is a game that I started off in my first project and using Bullet 2 years ago, and constantly updating it and finally come to the prototyping demo release. Just want to say thank you for all community in Bullets, you guys awesome! It is still in early dev, so be sure to give some feedb...

btManifoldPoint::getDistance() penetration question

Happy New Year guys, Sorry that I have a simple question regarding btManifoldPoint::getDistance(), from what i know is that if the distance is less than 0, the penetration happens. My question now is that, how do i determine which direction of distance is it giving? For e.g, I have a point, and with...

Compound Shape's children with different Friction ?

It seems like Bullet does not support Compound Shape with different friction children.

How do i achieve this ?

Re: btColllisionObject wobbling left and right plus in and o

Hi could you illustrate the situation more in detail? Because there can be many factors such as the shape of your object, the collision surface angle, collision surface friction, the collision target type (non-movable / movable), object's DISABLED_DEACTIVATION flag etc, all of these can affect the c...

Re: use btAlignedObjectArray<myObj *> to create new object

Thank you bro!
I changed to other style so to avoid complicated delete heap memory process.

and thanks for your answer =)

use btAlignedObjectArray<myObj *> to create new object ?

Hi guys, I am using btAlignedObjectArray<myObj *> to create new object, but when i try to remove it, i have problem. My code is below : class myObj { int index; myObj(int index) ... ~myObj() ... }; btAlignedObjectArray<myObj *> myArray; myArray.push_back( new myObj(1) ); myArray.push_back( new myObj...

Compound Shape Children Ray Test ?

Hi guys, bullet doesn't seem to return the collision shape of the children of compound shape, how do i determine which children object is being ray tested?

Thanks.

(Urgent) Loading Skeletal Animation with Bullet?

Hi guys,

I am trying to load the skeletal animation from (.b3d) or (.x) or (.dae) files,
but having no clue how to load them into bullet engine and manipulate the joints.

May i know if someone has a sample / guide for me?

Thank you, need it urgently. :oops:

Trying to glue 2 objects together but it offset from origin.

Greetings, I am facing some problem with gluing two objects together at a fixed orientation. The problem is that, when i had multiple constraints applied (I'm using hinge) the objects started to decay from its original positions . I had increased setOverrideNumSolverIterations to 1000 times iteratio...

How to obtain impulse / force ?

hi guys,

how do I obtain impulse / force value without letting bullet actually apply the forces on the body? (upon collision)

Thanks =)

How to avoid large impulse due to overlapping?

My objects are overlapping and suddenly it spike up and jump into sky due to large impulse,
how do I handle the impulse response so that I can limit the large impulse / discard the incredibly large impulse before it applied?

Thanks guys!

Bullet Constraint Bug Report.

Hi guys, I would like to report a bug since I have been asking around about this question few weeks ago but no solution to work out. So I am guessing it could be a bug or so (I am not sure), hopefully someone could also try this out and let me know if I am the only one or it is really a bug and hopi...

Re: FPS dropped significantly after adding Constraints

Tried the featherstone multi-body or dantzig solver? They help keep iterations low, though dantzig with 50 objects might not give that great of results (speed wise) as it's currently set up. You can also try just overriding the joint iterations, rather than all constraints. It'll improve speed a bi...

Re: FPS dropped significantly after adding Constraints

Upss sorry, i mean i tested with 100-500 iterations range, all are dropping significantly after first constraint. :lol:
Plus, if i don't set the iterations high enough, the objects are like swinging and fall off from its original pivots, which looks ugly ;'O
