Member Function Documentation

◆ any_cast()

static T any_cast ( const boost::any &  _value)
inlinestaticinherited

Helper function for performing any_cast operations in SetParam.

This is useful because the PresetManager stores the output of sdf::Element::GetAny as boost::any values in its parameterMap and calls SetParam with these values. Prior to libsdformat8, the GetAny function returned boost::any, but it now returns std::any. This helper is used in SetParam to first check if a boost::any value contains a std::any, and if so, perform a std::any_cast<T>. Otherwise, it returns boost::any_cast<T>.

Parameters
[in]_valueValue to cast to type T.
Returns
Value cast to type T.

◆ UpdateCollision()

virtual void UpdateCollision ( )
virtual

Update the physics engine collision.

This function works in tandem with PhysicsEngine::UpdatePhysics() to update the world. This function will be called even if the physics is disabled (when World::PhysicsEnabled()) returns false). Which updates are done in which of the two functions PhysicsEngine::UpdateCollision() and PhysicsEngine::UpdatePhysics() is to some extent left to the implementing physics engine. The intention is that PhysicsEngine::UpdateCollision() will update the collision states of the world, including contact information, and PhysicsEngine::UpdatePhysics() will update the dynamics of the world, i.e. advance the world and react to the collision state. However for some physics engines, both is done in one step, or providing the contact information separately in UpdateCollision() would mean double work, as it can't be avoided to be done again in PhysicsEngine::UpdatePhysics() - in this case it is better that PhysicsEngine::UpdateCollision does not actually update collision and contact information, and instead leaves it to UpdatePhysics(). There should be one exception however when it still does make this update: If World::PhysicsEnabled() returns false, and therefore PhysicsEngine::UpdatePhysics() will not be called in the update step, then PhysicsEngine::UpdateCollision will need to ensure that collision and contact information will still be updated.

Implements PhysicsEngine.

◆ UpdatePhysics()
