回答1:

You can use void drawRect( Point origin, Point destination ); declared in CCDrawingPrimitives.

Call this method inside draw() method of any subclass of CCNode like:

void TestNode::draw() {
    drawRect(Point::Point(10,10), Point::Point(40,40));
}

回答2:

You can try

DrawPrimitives::drawRect(const cocos2d::Point origin, const cocos2d::Point destination);

回答3:

You can also use this code snippet:

auto rectNode = DrawNode::create();
Vec2 rectangle[4];
rectangle[0] = Vec2(-50, -50);
rectangle[1] = Vec2(50, -50);
rectangle[2] = Vec2(50, 50);
rectangle[3] = Vec2(-50, 50);

Color4F white(1, 1, 1, 1);
rectNode->drawPolygon(rectangle, 4, white, 1, white);
this->addChild(rectNode);
