Wow! This is useful!
Wow! Everyone should read this! This useful stuff! Especially the camera tricks, those are awesome. All I can say is I'm extremely impressed. By the way, I do know another way to do the camera pan thing. I you have the same set of objects that are rushing by repeatedly (like turrets on a gunship as a character runs through the ship) you can put them on a movie clip, tween them to move inside the clip, then simply have two or copies of this on separate layers. However, this has very few applications and is slightly noobish, but it does the job a lot more quickly then your method when appropriate. The line proportioning thing for camera pans was genius, I will likely find this to be very useful. Thanks for your efforts to help the NG population with useful advice! This is simply outstanding. Can't wait for the sequel! But please, for loading times' sake, please don't combine this and the new one together... Just provide links in the Author's Comments. Plus, we can all get more experience that way!
Basically, my opinion says that this tutorial is simply awesome! Keep it up! :D
