我已经实施了 BXGY 自定义促销。为了简化我的情况，假设您的购物车中有 X 个产品后，您将获得 Y 个免费产品。
如果我在购物车中有 2*X 符合条件的产品，则预期行为是获得 2*Y 免费产品。
我的问题是多次解雇该促销活动。如果我将多重射击的最大计数设置为 4，那么尽管我在购物车中有 2*X 产品，但动作（获得免费产品）会被激活 4 次。
所以我的结论是，我需要消费符合条件的产品（该产品的条目），比如用户获得的免费产品被消费，因此他们无法参与另一次促销的资格。
我的研究结论是我需要消耗 (YFreeGift)RAOAction 中的条目，但是我需要检索所有有条件的产品，我觉得这不是正确的方法（条件在行动）。
有人知道如何消费符合条件的参赛作品吗？
