Detailed Description

with the methods from this class you can set the behavior of each contac-point

this class is for creating custom behavior between material GroupIDs. this class must not be inherited or instantiated directly in any way, you can obtain an object of this class in the contact-callback from the contactJoint and iterate through all contacts using the getNext-function

Member Function Documentation

◆ _getNewtonMaterial()

NewtonMaterial * OgreNewt::Contact::_getNewtonMaterial ( )
inline

get the NewtonMaterial from this callback.

Definition at line 199 of file OgreNewt_ContactJoint.h.

◆ getBody0()

OgreNewt::Body * OgreNewt::Contact::getBody0 ( ) const
inline

get the first body

Definition at line 96 of file OgreNewt_ContactJoint.h.

◆ getBody1()

OgreNewt::Body * OgreNewt::Contact::getBody1 ( ) const
inline

Definition at line 97 of file OgreNewt_ContactJoint.h.

◆ getFaceAttribute()

unsigned OgreNewt::Contact::getFaceAttribute ( ) const
inline

get the face ID of a TreeCollision object

Definition at line 100 of file OgreNewt_ContactJoint.h.

◆ getForce()

Ogre::Vector3 OgreNewt::Contact::getForce ( ) const

force of the collision

only valid for objects in a stable state (sitting on top of each other, etc)

Definition at line 60 of file OgreNewt_ContactJoint.cpp.

◆ getNext()

Contact OgreNewt::Contact::getNext ( ) const

get the next contact from the parent contact-joint

Definition at line 54 of file OgreNewt_ContactJoint.cpp.

◆ getNormalSpeed()

Ogre::Real OgreNewt::Contact::getNormalSpeed ( ) const
inline

get the Collision ID of a body currently colliding

speed of the collision

Definition at line 106 of file OgreNewt_ContactJoint.h.

◆ getPositionAndNormal()

void OgreNewt::Contact::getPositionAndNormal ( Ogre::Vector3 &  pos,
Ogre::Vector3 &  norm,
OgreNewt::Body *  body 
) const
inline

get positoin and normal of the collision

Definition at line 115 of file OgreNewt_ContactJoint.h.

◆ getTangentDirections()

void OgreNewt::Contact::getTangentDirections ( Ogre::Vector3 &  dir0,
Ogre::Vector3 &  dir1,
OgreNewt::Body *  body 
) const
inline

get the tangent vectors of the collision

Definition at line 131 of file OgreNewt_ContactJoint.h.

◆ getTangentSpeed()

Ogre::Real OgreNewt::Contact::getTangentSpeed ( int  index) const
inline

get tangent speed of the collision

Definition at line 148 of file OgreNewt_ContactJoint.h.

◆ operator bool()

OgreNewt::Contact::operator bool ( ) const
inline

return true, if this is not a valid contact (end of the contact-list!)

Definition at line 88 of file OgreNewt_ContactJoint.h.

◆ remove()

void OgreNewt::Contact::remove ( )

removes the contact from the parent contact-joint, this means newton doesn't process this contact

use this function, when you want to ignore this specific contact, but you need to get the next contact before, because this will invalidate this class (set all pointers to zero!)

Definition at line 67 of file OgreNewt_ContactJoint.cpp.

Ogre::Real  kinetic,
int  index 
)
inline

set static friction for current contact

Definition at line 163 of file OgreNewt_ContactJoint.h.

◆ setFrictionState()

void OgreNewt::Contact::setFrictionState ( int  state,
int  index 
)
inline

set friction state of current contact

Definition at line 160 of file OgreNewt_ContactJoint.h.
