Detailed Description

This class represents a ball joint, which is simply fixed connection in one point where the rotation around this point is not limited. It can be defined by an Anchor-point.

Member Function Documentation

void BallJoint::attachJoint	(	dBodyID	obj1,
		dBodyID	obj2
	)			[protected, virtual]

This method is called if the joint should be attached. It creates the ODE-joint, calculates the current anchor-position and attaches the Joint.

Parameters:

	obj1	first ODE-object to attach with
	obj2	second ODE-object to attach with

Implements Joint.

void BallJoint::detachJoint

(

)

[protected, virtual]

This method is called if the joint should be detached.

Implements Joint.

void BallJoint::getMemberValue	(	std::string	type,
		void *	result
	)			[virtual]

This method copies the value of the field with the passed name to the result-pointer. It is a little helper to avoid type-casts when accessing joint-pointers.

Parameters:

	type	name of the field
	result	destination where the value should be stored

Implements Joint.

void BallJoint::setAnchor	(	float	anchorX,
		float	anchorY,
		float	anchorZ
	)

This method sets the Anchor of the Joint in OBJECT-COORDINATES!!! This means that the Anchor is relative to the position of the main EntityTransform. Take care that the Anchor-offset is also scaled by the scale-Value of the EntityTransform. The reason for using object coordinates is because modelers can easily read the offset out of the modelling application.

Parameters:

	anchorX	X-position of the Anchor
	anchorY	Y-position of the Anchor
	anchorZ	Z-position of the Anchor

void BallJoint::setMemberValue	(	std::string	type,
		void *	source
	)			[virtual]

Implements Joint.
