BodyPath Class

This class represents a path along which an arbitrary rigid body can be moved. For example, it allows for creation of a physically simulated train moving along the railtrack. BodyRigid and BodyPath should be connected together with JointPath.

Notice
The path is a spline along which an object can be moved.

BodyPath Class

Members


BodyPath ()

Constructor. Creates a path with default properties, along which a rigid body is moved.

BodyPath (const Ptr<Object> & object)

Constructor. Creates a path with default properties for the given object. Along this path a rigid body is moved.

Arguments

  • const Ptr<Object> & object - Object represented with the new path body.

Math::Vec3 getClosestPosition (const Math::Vec3 & position)

Finds the point on the path which is the closest to the given reference point.

Arguments

  • const Math::Vec3 & position - Coordinates of the reference point.

Return value

Coordinates of the reference point, if the path exists; otherwise, the (0 0 0) vector is returned.

void setPathName (const char * name, int dynamic = 0)

Reloads the internal path transformation.

Arguments

  • const char * name - Path to the path file to be set.
  • int dynamic - The dynamic flag:
    • 0 - If the reloaded path is changed in run-time, paths loaded from the same file will be also changed.
    • 1 - If the reloaded path is changed in run-time, paths loaded from the same file won't be changed.

const char * getPathName ()

Returns a name of the path along which physical objects are moving.

Return value

Path to the path file.

Ptr<Path> getPath ()

Returns the path along which physical objects are moving. By using this function, you can change velocity of the objects moving along the path, their transformation, etc.

Return value

Instance of the Path class.

Math::quat getClosestRotation (const Math::Vec3 & position)

Finds the point on the path which is the closest to the given reference point and returns rotation set by the path in this point.

Arguments

  • const Math::Vec3 & position - Coordinates of the reference point.

Return value

Rotation set by the path in the found point, if the path is exists; otherwise, the (0 0 0 1) quaternion is returned.
