单例值变量 - 域未定义

Question

我一直在尝试制作游戏。游戏包括9件带点的游戏。该片的每个面都有0,1或2个点。

[2,2,0,0,1,0] 

这是一件作品。这件作品，看起来像这样：

 [[2,2,0,0,1,0], %%peca1
           [2,1,0,0,1,1], %%peca2
           [2,0,0,0,1,1], %%peca3
           [2,0,0,0,0,0], %%peca4
           [1,0,0,0,1,0], %%peca5
           [1,0,0,0,0,0], %%peca6
           [1,0,0,0,0,0], %%peca7
           [0,0,0,0,1,0], %%peca8
           [0,0,0,0,0,0]]), %%peca9

这些都是件。 （正面，右面，bacl，右，顶部，下面）

这是，当我运行它时，我收到消息

[V2,V5,V7,V11,V12,V16,V17,V18,V19,V23,V26,V29,V31,V35,V41,V47,V53] - singleton variables

任何帮助或建议？

致以最诚挚的问候，

Luis Costa
