A force generator that applies spring forces to 2d rigid bodies. One instance may be used for multiple rigid bodies, if they are connected to the same anchor point in the world via the same spring.
| virtual bl7::rigidbodies2::AnchoredSpring::~AnchoredSpring | ( | void | ) | [inline, virtual] |
Destructor.

| const float | d, | |||
| const float | s0, | |||
| const ml7::Vector2 & | local_point = ml7::Vector2(0.0f) | |||
| ) | [inline] |
Explicit constructor with parameters specifying the anchor point in world coordinates on the other side of the spring, the spring constant d, the rest length of the spring s0 and, finally, the local connection point of the the rigid body to apply the force to.
| const ml7::Vector2& bl7::rigidbodies2::AnchoredSpring::get_anchor | ( | ) | const [inline] |
Returns the anchor point of the spring in world coordinates.
| const ml7::Vector2& bl7::rigidbodies2::AnchoredSpring::get_local_point | ( | ) | const [inline] |
Returns the local connection point of the rigid body to apply forces to.
| float bl7::rigidbodies2::AnchoredSpring::get_rest_length | ( | ) | const [inline] |
Returns the rest length of the spring.
| float bl7::rigidbodies2::AnchoredSpring::get_spring_constant | ( | ) | const [inline] |
Returns the spring constant.
| void bl7::rigidbodies2::AnchoredSpring::set_anchor | ( | const ml7::Vector2 & | anchor | ) | [inline] |
Sets the anchor point of the spring in world coordinates.
| void bl7::rigidbodies2::AnchoredSpring::set_local_point | ( | const ml7::Vector2 & | local_point | ) | [inline] |
Sets the local connection point of the rigid body to apply forces to.
| void bl7::rigidbodies2::AnchoredSpring::set_rest_length | ( | const float | s0 | ) | [inline] |
Sets the rest length of the spring.
| void bl7::rigidbodies2::AnchoredSpring::set_spring_constant | ( | const float | d | ) | [inline] |
Sets the spring constant.
