The specific issue centered around creating multiple keyframes, but only changing the original drawing.具体的问题围绕创建多个keyframes ，但不但改变了原始绘图。 The result was an animation that didn’t change at all over time, since each keyframe only contained the same identical drawing.结果是一动画并没有改变在所有随着时间的推移，由于每个关键帧仅载有相同的相同的绘图。

The confusion lies in the fact that Toon Boom (correctly) treats frames differently from the objects within the frame, just like Flash.混乱，关键在的事实，香椿繁荣（正确）对待不同的框架从物体内部的框架，就像闪光。 Kroaky meant to copy and paste the objects in the frame, but instead copied the frame itself, which lead to frustration. kroaky意味着复制并粘贴的对象框架，而是复制的框架本身，从而导致沮丧。 I attempted to show fast and efficient way of creating the scenario Kroaky describes with a simple 16 frame animation containing seven drawings.我试图表现出快速和有效率的方式建立的情况kroaky介绍了一个简单的16帧动画载有7图纸。 Here are the steps I took (click on each image to enlarge it).这里是我的步骤（点击每个图像放大） 。

I started by creating the glass drawing element, and then drew a basic window using the pencil tool and line tool.我开始创造玻璃图形元素，然后提请一个基本的窗口使用铅笔工具和线工具。 Notice how in the timeline at the bottom the “glass” element spans 16 frames.通知，如何在时间线在底部的“玻璃”分子跨越16张。

I then used the pencil tool with the smoothness level turned all the way down to one to start creating my initial cracks in the glass on a new drawing element, on the first frame.然后我用铅笔工具，具有光滑的水平把所有的方式下降至一开始创造我初步的裂缝在玻璃上一个新的图形元素，对第一帧。 With the smoothness practically turned off, we’ll get some random jaggedness in our line shapes, which will help the believability of our cracked lines.与光滑几乎关闭，我们会得到一些随机jaggedness在我们的线形状，这将有助于我们的可信度破获线。

Then, instead of adding a new keyframe, I used the drawing select tool (indicated here with a red arrow ), to choose the drawing I just created (not the frame itself).然后，而不是加入一个新的关键帧，我用了绘图选择工具（在这里表示，与一个红色箭头 ） ，选择绘图我刚才创建的（而不是框架本身） 。 I copied that, moved to the next frame, then pasted the drawing. i复制，转移到下一帧，然后粘贴绘图。

If you were to look at the Exposure Sheet right now you would see that there are two drawings (as Ugo stated in the forums), as well as two frames in the “crack” level in the animation (indicated here with a red arrow ).如果你看看曝光表的权利，现在，您会看到有两个图纸（ ugo说明，在论坛中） ，以及2帧，在“裂缝”的水平，在动画（表示在这里与一个红色箭头 ） 。

The remainder of the animation is simply repetition: add a bit more cracking glass to the current frame, select everything you just drew, copy, move to the next frame, paste.其余的动画是简单的重复：添加多一点打击玻璃到目前的框架，选择一切你刚才提请，复制，移动到下一帧，粘贴。 On the seventh frame I decided the point was made and simply extended the final frame out over the remainder of the animation (’R’ is the keyboard shortcut to do this by default).关于第七框架，我决定有人指出，简单地延长最后帧以上的其余部分，动画（ '是键盘快捷键来做到这一点，默认） 。

And here is the final product:这里是最后的产品：
