新的物理引擎叫physicsBody

创建物理scene

auto scene = Scene::createWithPhysics();

添加调试信息 这样可以让刚体附加方框显示出来

 scene->getPhysicsWorld()->setDebugDrawMask(PhysicsWorld::DEBUGDRAW_ALL);

void Stage::addEdgeBox()
{
	auto visibleSize = Director::getInstance()->getVisibleSize();
	//建立刚体
	auto edgeBox = PhysicsBody::createEdgeBox(visibleSize);
	//创建图形
	auto shape =Node::create();
	//刚体附加到图形
	shape->setPhysicsBody(edgeBox);
	this->addChild(shape);
}

</pre><span style="color: rgb(51,51); font-family: sans-serif; font-size: 24px;">shape的默认位置是（0,0），但是这个是node的中心位置，我们把它设置到屏幕中心</span><br style="Box-sizing: border-Box; color: rgb(51,51); font-family: sans-serif; font-size: 24px;" /><p style="Box-sizing: border-Box; margin-top: 0px; margin-bottom: 0px; padding-top: 0.2rem; padding-bottom: 0.3rem; font-family: Arial,'Microsoft YaHei'; font-size: 0.7rem; color: rgb(51,51); line-height: 0.875rem; word-break: break-all;"></p><pre name="code" class="cpp" style="Box-sizing: border-Box; font-family: Arial,245);">shape->setPosition(visibleSize.width/2,visibleSize.heigh

设置好了世界，现在把精灵player变成刚体，只需要一句话

player->setPhysicsBody(PhysicsBody::createBox(player->getContentSize()));
