     * 注册方法同上，最大的区别在于这个数组的顺序必须保持好。如果随意调换其中的顺序，或注销不在数组末尾的图片，就会导致地图上最终呈现的素材发生错位。因此，新勾选的图片总会被自动追加到数组的末尾。
     * 比起常规素材，额外素材最大的好处有几点：
-        1. 图片没有数量限制。常规素材的总数量最多只允许不到一万个，而额外素材每张图片上的图块数量最多允许一千个。
+        1. 图片没有数量限制。常规素材的总数量最多只允许不到10000个，而额外素材每张图片上的图块数量最多允许3000个。
         2. 查看和绘制更为方便。常规素材每个图块独占一行，每列为一帧，导致不方便观察，且用多个图块拼图必须逐图块绘制。额外素材都是静止的，所以每个图块只占一格，多个图块可以在准备素材时就直接以相邻的样子绘制在同一张图片上，绘制地图时直接从素材区拖动来批量框选，再在地图区单击成片绘制或拖动平铺。
         3. 批量替换也更为方便。譬如您如果想制作形如“一场大战/天灾过后/多年以后，村庄/城镇化为了一片废墟”的效果，可以预先准备两张甚至更多张相同规格的额外素材图片，然后在适当的时候遍历某个/某些楼层的图块ID，将以“X1”开头的图块统一替换为“X2”开头等。发布单机版游戏时，您也可以提供多张相同规格的额外素材图片供玩家直接替换皮肤风格。
 5. **使用动画：**`project/animates`文件夹中的文件名（不含后缀，请注意与`animates.png`相区分）。
