C++ (Cpp) InitializeJointDef Examples

Example #1

b2JointDef* ConstraintRope2D::GetJointDef()
{
    if (!ownerBody_ || !otherBody_)
        return 0;

    b2Body* bodyA = ownerBody_->GetBody();
    b2Body* bodyB = otherBody_->GetBody();
    if (!bodyA || !bodyB)
        return 0;

    InitializeJointDef(&jointDef_);
    jointDef_.localAnchorA = ToB2Vec2(ownerBodyAnchor_);
    jointDef_.localAnchorB = ToB2Vec2(otherBodyAnchor_);

    return &jointDef_;
}

Example #2

File: ConstraintRope2D.cpp Project: Gotusso/Urho3D

b2JointDef* ConstraintRope2D::CreateJointDef()
{
    if (!ownerBody_ || !otherBody_)
        return 0;

    b2Body* bodyA = ownerBody_->GetBody();
    b2Body* bodyB = otherBody_->GetBody();
    if (!bodyA || !bodyB)
        return 0;

    b2RopeJointDef* jointDef = new b2RopeJointDef;
    InitializeJointDef(jointDef);

    jointDef->localAnchorA = ToB2Vec2(ownerBodyAnchor_);
    jointDef->localAnchorB = ToB2Vec2(otherBodyAnchor_);
    jointDef->maxLength = maxLength_;

    return jointDef;
}

Example #3

b2JointDef* ConstraintGear2D::GetJointDef()
{
    if (!ownerBody_ || !otherBody_)
        return nullptr;

    b2Body* bodyA = ownerBody_->GetBody();
    b2Body* bodyB = otherBody_->GetBody();
    if (!bodyA || !bodyB)
        return nullptr;

    if (!ownerConstraint_ || !otherConstraint_)
        return nullptr;

    b2Joint* jointA = ownerConstraint_->GetJoint();
    b2Joint* jointB = otherConstraint_->GetJoint();
    if (!jointA || !jointB)
        return nullptr;

    InitializeJointDef(&jointDef_);
    jointDef_.joint1 = jointA;
    jointDef_.joint2 = jointB;

    return &jointDef_;
