    pub base: B2jointDef<D>,
    pub ground_anchor_a: B2vec2,
    pub ground_anchor_b: B2vec2,

}

Pulley joint definition. This requires two ground anchors, two dynamic body anchor points, and a pulley ratio.

Fields

base: B2jointDef<D>

ground_anchor_a: B2vec2

The first ground anchor in world coordinates. This point never moves.

ground_anchor_b: B2vec2

The second ground anchor in world coordinates. This point never moves.

local_anchor_a: B2vec2

The local anchor point relative to body_a’s origin.

local_anchor_b: B2vec2

The local anchor point relative to body_b’s origin.

length_a: f32

The a reference length for the segment attached to body_a.

length_b: f32

The a reference length for the segment attached to body_b.

ratio: f32

The pulley ratio, used to simulate a block-and-tackle.

Implementations

impl<D: UserDataType> B2pulleyJointDef<D>

pub fn initialize( &mut self, body_a: BodyPtr<D>, body_b: BodyPtr<D>, ground_anchor_a: B2vec2, ground_anchor_b: B2vec2, anchor_a: B2vec2, anchor_b: B2vec2, ratio: f32 )

initialize the bodies, anchors, lengths, max lengths, and ratio using the world anchors.
