Unable to setRotation to PhysicsBody::createBox in cocos2dx - cocos2d-x

Question

I'm able to rotate the sprite 90-degree angle but unable to change the angle of the physics body. My purpose is to connect multiple sprites with createBlock() to make a breakable tower object. I want to add setRotation() to PhysicsBody::createBox but error showed up and was unable to implement what I want to do. I googled for some solutions but wasn't able to find a helpful solution to my problem. I would love to hear some tips or examples from you!
Here is the function to create a Block sprite. Added 90 so that the sprite will be rotated to 90 degrees.
createBlock(BlockType::Block1, Point(586, 150), 90);
↓
void GameLayer::createBlock(BlockType type, Point position, float angle)
{
std::string fileName;
switch (type)
{
case BlockType::Block1:
fileName = "block1.png";
break;
case BlockType::Block2:
fileName = "block2.png";
break;
case BlockType::Roof:
fileName = "roof.png";
break;
default:
fileName = "stone.png";
break;
}
auto block = Sprite::create(fileName.c_str());
block->setPosition(position);
block->setRotation(angle);
block->setTag(T_Block);
PhysicsBody* body;
switch (type)
{
case BlockType::Block1:
case BlockType::Block2:
{
body = PhysicsBody::createBox(block->getContentSize(), PhysicsMaterial(0.5, 0.5, 0.3));
body->setDynamic(true);
body->setContactTestBitmask(0x01);
break;
}
case BlockType::Roof:
{
Point points[3] = {Point(-50, -25), Point(0, 25), Point(50, -25)};
body = PhysicsBody::createPolygon(points, 3, PhysicsMaterial(0.5, 0.5, 0.3));
body->setDynamic(true);
body->setContactTestBitmask(0x01);
break;
}
default:
{
body = PhysicsBody::createBox(block->getContentSize(), PhysicsMaterial(0.5, 0.5, 0.3));
body->setDynamic(false);
break;
}
}
block->setPhysicsBody(body);
addChild(block, Z_Block);
}

If you want to rotate not only the sprite but also physics, we must call setRotation(angle) after calling block->setPhysicsBody(body).
So, please fix code like below...
1st: block->setPhysicsBody(body);
next: block->setRotation(angle);
last: addChild(block, Z_Block);
I know your code and have experienced same problem before! I have this text book, too.(^ ^)
