Finish your scene!
Storyboard
Here is the scene we are working on
Arranging items with rotation
The items that just require translation and scaling are already in place. Now you can add items that also require rotation. Again, once you are happy with the scene, submit it for the director's final approval.

Does anyone have a good way of remembering the order of Scaling, Rotation, and Translation? I have a really hard time recalling the order and would love any suggestions on ways you remembered it.(21 votes)
One way might be the mnemonic SORT, since you have to sort the transformations into the right order (and ignore the O). Personally I would just think what would happen if I rotate and then scale (it would scale along the wrong axis), or translate and then rotate (it will move away from the point I translated to), and so on. That way the order should make sense.(40 votes)
I can't move the screen, so I'm unable to translate, rotate, or scale. Does anybody have a way to solve this?(9 votes)
From my point of view, it depends on your computer speed. I have a slow computer and a fast one, and it wont work on my slow one but with on my new one. I suggest buying a faster computer...(2 votes)

- You can't in this version, it's already in the scene. To move it you have to go to the Scaling items in a scene program.(6 votes)
Can I save this?(7 votes)
Yes. You have to click on submit score and then it automatically gets saved(6 votes)
why not have the arows to translate right and left point right and left?(6 votes)
The arrows to translate are up and down to help you infer that they are to increase or decrease the amount to translate by. I'm sure this is to emphasize that we are in fact only increasing a variable, which then is plugged into a formula for us to memorize.(4 votes)
- The Bo Peep won't go any farther and it will not let me pass unless she moves more to the right.(5 votes)
Try doing the transformations in the order: scale, rotate, translate. I had the same problem until I followed this order.(3 votes)
Why does the objects move zigzag when i translate after rotating? Is this a bug? (i've not seen this in 2d and 3d programs that i have used)(3 votes)
You are translating in the direction of the current orientation of the object. If Bo Peep's head is at an angle, translating in the y direction will move her at the same angle.(4 votes)
Why does it not show the entire picture? At least for me it doesn't on any of the practice.
How am I supposed to practice if I can't do anything?(3 votes)
wow this is old some of these comments from six years! SIX YEARS! That lady on the video is probably old!(3 votes)
