Re: Soft Body, joint

It seems to me that: m_softBodyWorldInfo.m_maxDisplacement = 0; has solved my problem.
but after the collision soft object is broken into pieces.

Re: Soft Body, joint

Here is a short video: https://www.dropbox.com/s/dg41r9ok67k5gvk/softbody_fly.mov?dl=0 Thus, I created the Soft Body object: m_softBodyWorldInfo.air_density = (btScalar)1.2; m_softBodyWorldInfo.m_gravity = btVector3(0, 0, 0); //_world.world->getGravity(); m_softBodyWorldInfo.m_dispatcher = _world.di...

Soft Body, joint

Hi, all. I want to create the simple deformation object. It will look like the wall which is deformed by shells. Thus, it must be static soft body object. Here is I'm creating Soft Body: - (id) initMeshToSoftBodyConverter:(BOOL)_static World:(ibWorld*)_world Name:(NSString*)_name SceneNode:(iSceneNo...

Re: Drag force, skid

Frankly speaking,
1) I haven't managed to setup right params for:

Code: Select all

setFriction ,setRollingFriction, setAnisotropicFriction
2) As for the method which will compensate for centrifugal force. I did my best, but there was no result.

Maybe you can help me to implement neither 1) or 2). Thanks.

Drag force, skid

Hi, all. There is an object which is controlled with applyCentralForce. All parameters like setFriction, setRollingFriction, setRestitution, setDamping are defined by default (thus, I changed nothing). Except for setAngularFactor, I setted up it like vec(0, 0, 0); My problem is when I want to turn t...

Re: Ice, hockey player

For controlling the Player I use the applyCentralForce, thus when the joystick was touched, the method is working: - (void) joystickManagerDidUpdate:(CGPoint)position Angle:(iDegree)angle Right:(BOOL)bRight Sharp:(BOOL)bSharp { [mBody applyCentralForce:iVector3(position.x * 1000000.0, 0.0, position....

Limit of force

Hi, all. Is it possible to set the limit of force? I'm meaning that there is any rigid body, that the user will be controlling it by applyCentralForce. Can I limit (set the max) force? For example, by tapping on button "W" the object receives the appCentralForce(5,0,0); And I want the rigid body to ...

Re: Collision between Soft Body and Rigid

Also what param is necessary to set up for rigidity/inflexibility/hardness? I mean if I need to create Soft body for very easy deformation? Thanks.

Re: Odd behavior for dynamic objects - sliding ignoring fric

Hi,

Have you managed to solve this problem? The thing is that I'm working on the same task: trying to make the hockey player.
If I'm using the applyCentralForce, it looks terrible. It seems to me that I can't set up correct parameters for Friction, etc.

Maybe you can help me :) Thanks.

Hi, all. I'm facing the trouble of creating the Real Hockey Player: there is simple game scene: floor: it's the ice; player: it's the hockey player. I need to control this player via keyboard. Before I worked on PhysX Ageia and I solved this task in the following way: mFloor->setFriction(0.2); mFloo...

Re: [Solved] High friction, objects sliding like on ice

Hi,

I'm facing with task - creating of hickey simulator. Could you help me?
What params(setFriction, setRollingFriction) are for plane and object?
What are you controlling the object(force or linearVelocity)?

It will be great if you could share this fragment of code. Thanks a lot.
