how to STOP forces (delete them) ???

hi,
I wanted to know if there si some kind of method
for stopping the forces instantly, or deleting them from an object.

You just need to apply an equal and opposite force!

is there not like another way?
like a function that says "object.stopForces();"
its an physic emulation world not a real one.

iits an physic emulation world not a real one.The point of the physics emulation is to as closely simulate the real world as possible. Otherwise, what would be the point?

ok,
I have thi problem ,
how can I delete,erase,stop and Y axis force inmedietly, OK with opposing forces but how?

although you shouldnt really do it, you could use

Ogre::Vector3 noforce (0.0, 0.0, 0.0);
body->setVelocity(noforce );
body->setOmega(noforce );

that would kill all forces.

combined with

body->getVelocity()
and ->getOmega();
you can work out which part of the current volcity to remove

you should be able to do something like// Get current velocity
Ogre::Vector3 oppositeForce = body->getVeolcity();
// Reverse it
oppositeForce = Ogre::Vector3::ZERO - oppositeForce;
// Apply it
body->addForce(oppositeForce);

Is it just gravity that you want to turn off?

If that is the case, just change the callbacks to include/exclude the downward gravity force for the objects you wish to turn the gravity on/off for...
