Question

我正在pygame中制作平台游戏。我正在为这个关卡添加暴民。我认为这与添加平台相同，但事实并非如此。我不断收到此错误： “ TypeError：'Mob'对象不可下标”。（底部的完整错误）。谁能解决这个问题并解释？注意：我要导入很多文件，所以会有很多导入。

GridBagLayout layout = (GridBagLayout)panel;
Component[] components = panel.getComponent();

for (each component in the array)
{
    GridBagConstraint gbc = layout.getConstraints( component )

    if (gbc.gridX == ?? && gbc.gridY = ??)
    {
        // remove the component from the panel
    }
}

panel.revalidate();

Answer 1

# Array with type of mob, and x, y location of the mob
level_enemies = [mobs.SLIME_WALK, 100, 400]

# Go through the array above and add mobs
    for enemy in level_enemies:
        enemy = mobs.Mob(enemy[0])
        enemy.rect.x = enemy[1]
        enemy.rect.y = enemy[2]
        enemy.player = self.player
        self.platform_list.add(enemy)

在此代码块中，enemy指的是mob.SLIME_WALK，100，然后是400。它们是ints，不能下标。

也许您打算将level_enemies声明为：

level_enemies = [[mobs.SLIME_WALK, 100, 400]]

如何解决：Pygame中的“ TypeError：'Mob'对象不可下标”？
