Physics Joint fixed problem

cocos2d-x C++
#1

Hi,

i just wanted to try the joints with physics world,
so i created two physics body and tried the PhysicsJointFixed class.

but when I run it,the app crashes.what’s wrong with it? :pensive:

here’s the code:

    circle = Sprite::create("cir.png");
    circle->setPosition(winSize.width/2 , winSize.height/2);
    auto circleBody = PhysicsBody::createCircle(circle->getContentSize().width/2 , PhysicsMaterial(0,0,0));
    circle->setPhysicsBody(circleBody);

    enemy = Sprite::create("cir.png");
    enemy->setPosition(winSize.width/2, winSize.height/2);
    auto enemyBody = PhysicsBody::createCircle(enemy->getContentSize().width/2 , PhysicsMaterial(0,0,0));
    enemy->setPhysicsBody(enemyBody);

    PhysicsJointFixed* joint = PhysicsJointFixed::construct(circle->getPhysicsBody(),enemy->getPhysicsBody()  ,Vec2(winSize.width/2 , winSize.height/2 ));
    this->getScene()->getPhysicsWorld()->addJoint(joint);
    addChild(enemy);
    addChild(circle);
#2

What method does it crash in? What method is the one you show?

I am pretty sure you’ll have to call joint->createConstraints() right after creating it.
