I’m in trouble. There is a problem when the flipper rebounds the ball. When the flipper is raised, the ball will sink into the flipper. Please tell me how to resolve.

// ball material setting
ballBody = MyBodyParser::getInstance()->bodyFormJson(ballSpr, “ball”, PhysicsMaterial(0.2f, 0.0f, 0.0f));

if (ballBody != nullptr)
{
    ballBody->setMass(10.0);
    ballBody->setMoment(100.0f);
    ballBody->setDynamic(true);
    ballBody->setRotationEnable(true);
    ballBody->setCategoryBitmask(ball_MASK);
    ballBody->setCollisionBitmask(flipper_MASK);
    ballBody->setContactTestBitmask(true); 
    ballSpr->setPhysicsBody(ballBody);
}

Try updating physics step manually. Search into docs or forum you will find solution for same.
