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 = True
    for 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 = False
                break
    if 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：
