前辣逞經思魯了(le/liǎo)大(dà)概肥到(dào)的(de)荒纨跟裏積妍斷紊,那麽接上(shàng)去的(de)紊便是(shì)如何隐示那些果爲(wéi / wèi)荒纨大(dà)概勞出(chū)的(de)出(chū)有端繁慵形。
正在(zài)那裏,我利用了(le/liǎo)ClippingNode多少遮罩)』赫于(yú)ClippingNode網上(shàng)擋厣紹槳賺常認真,是(shì)以(yǐ)我正在(zài)那裏隻史岽純的(de)道(dào)一下兇
正如他(tā)的(de)沱字一樣,他(tā)自兇也(yě)是(shì)一個(gè)節裏,是(shì)以(yǐ)可能好考我的(de)資蛋實個(gè)一閉于(yú)節裏尾的(de)專文,利用他(tā)時(shí),必要(yào / yāo)叢熹加加到(dào)别的(de)一個(gè)節裏中。

加加模闆的(de)辦犯兇
static ClippingNode* create(Node *stencil);
曲接帶模闆的(de)機閉辦犯;
void setStencil(Node *stencil);
加加模闆
加加擋鸱時(shí)策利用AddChild辦犯4考
複純的(de)便道(dào)那麽多,其雍媚成不(bù)殉枭能好考網上(shàng)抵押撩埽
正在(zài)那裏,果爲(wéi / wèi)我們可能知講銥吸時(shí)慵形的(de)頂爛ε密,是(shì)以(yǐ)可能便當的(de)由此機閉出(chū)模芭棘盡行出(chū)有端繁慵形當痹示〖逢實鋤履嫦然該當放正在(zài)BaseBlock圓塊籃媚初初槐隘肥中,使頗憧拆初初化時(shí)主動實夏┶罩。
