pgzrun 拼图游戏制作过程详解（6，7）

6. 检查拼图完成

• 初始化标记成功的变量Is_Win

Is_Win=False

• 当鼠标点击小拼图时，判断所有小拼图是否都在正确的位置，并更新Is_Win。

def on_mouse_down(pos,button): # 当鼠标被点击时# 略is_win = Truefor i in range(6):for j in range(4):Square = Squares[i * 4 + j]if not (Square.left == Square_size * j and Square.top == Square_size * i) :is_win = Falsebreakif is_win:Is_Win=True

• 在draw()绘制函数中加入成功判断，并在窗口打印出成功信息。

 def draw():# 略if Is_Win:screen.draw.text("游戏胜利！",(WIDTH/2-100,HEIGHT/2-50),\fontsize=50,fontname='s',color="blue")

执行效果如下图所示：

7. 添加游戏提示线

• 当拼图未完成时，为每一个小拼图绘制黑色边框，用以区分每一个小拼图的边界。

def draw():# 略for i in range(5):screen.draw.line((i*Square_size,0),(i*Square_size,HEIGHT),"black")for i in range(7):screen.draw.line((0,i*Square_size),(WIDTH,i*Square_size),"black")

• 当拼图未完成时，为当下鼠标点击的小拼图绘制红色边框。

def draw():# 略if clickID_1!=-1:screen.draw.rect(Rect((Gird[clickID_1].left,Gird[clickID_1].top),\(Square_size,Square_size)),"red")

执行效果如下图所示：
