Five timeline habits that keep Animate files tidy
A timeline is a shared workspace, even when you are the only person using it. These habits make a file readable six months later.
1. Name every layer
"Layer 14" tells nobody anything. Name layers after what they hold: hero-body, shadow, hit-area.
2. Group with folders
Put related layers in a folder and collapse it. A character with twelve layers becomes one line you can lock, hide or move as a unit.
3. Use frame labels, not frame numbers
Scripts that say gotoAndPlay("walk") survive edits. Scripts that say gotoAndPlay(47) break the first time someone inserts a frame.
4. Set registration points on purpose
Decide where a symbol rotates and scales from before you animate it. A door should pivot at the hinge, a wheel at its centre.
5. Keep code in one place
Scatter frame scripts across a hundred keyframes and nobody can find the bug. Prefer a single code layer, or better, a document class that owns the behaviour while the timeline owns only the drawing.
Bonus: save a short "read me" text layer on the first frame with the file's purpose, frame rate and the date of the last major change.
