游戏内clickpower变量无法通过升级按钮提升，求代码修正

问题出在变量更新的代码逻辑上：你仅执行了算术运算，但未将运算结果重新赋值给变量，导致clickpower和puan的数值始终没有实际变化。

修复后的完整代码片段 #

clickpower = 1

def on_mouse_down(button,pos):
    global puan, clickpower
    if button == mouse.LEFT:
        if upgbutton.collidepoint(pos):
            if puan >= 10:
                upgbutton.pos = (744,80)
                animate(upgbutton, tween= "bounce_end", duration = 1, x = 744, y = 100)
                clickpower += 1  # 修复：将运算结果赋值回变量，实现数值提升
                puan -= 10       # 修复：将运算结果赋值回变量，实现数值扣除
            else:
                upgbutton.pos = (734,80)
                animate(upgbutton, tween= "accel_decel", duration = 0.3, x = 744, y = 100)

关键修改说明 #

• clickpower += 1是clickpower = clickpower + 1的简写，能真正将点击力数值加1并更新变量
• puan -= 10是puan = puan - 10的简写，会正确扣除10点puan并更新变量
