我用的是cocos2d-x 3.0
auto stencil = DrawNode::create();
static Point triangle;
triangle = Point(-40, -40);
triangle = Point(40, -40);
triangle = Point(0, 40);
static Color4F green(0, 1, 0, 1);
stencil->drawPolygon(triangle, 3, green, 0, green);
auto clipper = ClippingNode::create();clipper->setAnchorPoint(Point(0.5, 0.5));
clipper->setPosition( Point(100, 100) );clipper->setStencil(stencil);
clipper->setInverted(true);
// containerAddedAsChild->addChild(clipper, 20); // 工作正常
containerRenderedToTexture->addChild(clipper, 20); // 异常，画出来整个的未clip的素材，并且周围都是纯白色
auto img = Sprite::create(“test_sprite.png”);
img->setAnchorPoint(Point(0.5, 0.5));
clipper->addChild(img);
试过了autodraw，visit，加在一个node上再visit等等
总之，clippingnode和rendertexture一起用，就不正常了，求解答。
