Using the Comet.ana file as a reference, you are to try your best to create your very own movie clip symbol

I can do that — but first a quick question: which authoring environment do you want instructions for (Adobe Animate / Flash Professional for ActionScript 3.0, Adobe Animate HTML5 Canvas / CreateJS, or something else)? Also: do you want only the visual symbol (timeline/tweens) or a symbol you can control with code?
Below are two compact, ready-to-follow workflows (one for Adobe Animate → HTML5 Canvas / CreateJS, one for Adobe Animate → ActionScript 3). Each produces a reusable movie-clip symbol of a comet (head + trailing tail + sparkle) and shows how to place and animate it on the stage.
If you tell me which environment you prefer I can tailor further or produce a downloadable .fla/.an file structure.
Workflow A — Adobe Animate (HTML5 Canvas / CreateJS)
1. Create symbol
- Draw comet head (small circle/ellipse) on the Stage using the Oval tool. Fill with a radial gradient: bright white/yellow center to orange edge.
- Draw tail: a tapered polygon or long ellipse behind the head, filled with a linear gradient from semi-opaque yellow to transparent.
- Select head+tail, right-click → Convert to Symbol → Movie Clip. Name it “Comet_mc”. Set Registration to center.
2. Edit symbol timeline (double-click Comet_mc)
- Create 3 layers: Body, TailGlow, Sparks.
- Body: put the head graphic on frame 1.
- TailGlow: put the tail shape on frame 1, apply a blur filter (Properties panel → Filters → Blur) for glow.
- Sparks: create a small star-shaped graphic; convert it to a nested movie clip “Spark_mc” with a short self-animating timeline (e.g., scale/fade over 8–12 frames and then stop). Place several instances, staggered frames for subtle sparkle animation.
- Extend symbol timeline to, say, 24 frames and if you want looping inside the clip, place keyframes and add slight motion (like tail sway). Otherwise keep it single-frame; movement will be done via main timeline/code.
3. Back at the main Stage
- Drag Comet_mc to the Stage. Give it an instance name (Properties panel) like cometInstance.
- Animate across the stage:
- Option A: Motion tween — place the comet off-stage left on frame 1, Insert Keyframe at frame 60, move the comet off-stage right, right-click between and Create Motion Tween. Add easing (Ease In/Out) in Properties for natural motion.
- Option B: Code (CreateJS): in the Actions layer add:
var comet = exportRoot.cometInstance; // if using exported root
comet.x = -100;
createjs.Tween.get(comet, {loop:true})
.to({x: canvas.width + 100}, 2500, createjs.Ease.quadInOut)
.wait(200)
.to({x: -100}, 1); // restart quickly (or use yoyo loop)
- Alternatively, use an enterFrame update to move and reset.
4. Export
- Test (Control → Test) — if HTML5 Canvas, Animate publishes a createjs-based HTML + JS. The comet will move across the stage with its internal sparks animating.
Workflow B — Adobe Animate (ActionScript 3.0)
1. Create the symbol as above: draw head, tail, sparks. Convert to Movie Clip symbol; linkage/class name: Comet (or default). Set Registration = center. Make nested Spark movie clips that animate internally (scale & alpha fade).
2. Place instance on stage, give instance name comet_mc.
3. Simple AS3 code to move and loop:
- On the Document class or in frame 1 actions:
import flash.events.Event;
comet_mc.x = -100;
comet_mc.y = 150;
addEventListener(Event.ENTER_FRAME, onEF);
function onEF(e:Event):void {
comet_mc.x += 10; // speed
// optional: slight vertical sine for swoop:
comet_mc.y = 150 + Math.sin(comet_mc.x / 20) * 8;
if (comet_mc.x > stage.stageWidth + 100) {
comet_mc.x = -100;
}
}
4. Filters & blend
- In Properties for Comet_mc or inside symbol: add Glow filter or Blur for trail glow; set blend mode to ADD (in Properties) for bright additive tail effect.
Practical tips and polish
- Registration point: use center so rotating/scaling/position is predictable.
- Keep the tail a separate layer so you can tween its shape for a trailing wobble if desired.
- For many comets on screen, convert repeated tail shapes to bitmap cached assets (Properties → Cache as Bitmap) to improve performance.
- For HTML5 Canvas, you can create a reusable factory (new lib.Comet()) and spawn many with different random speeds/angles.
- Want parallax or depth? Make 3 sizes of comet symbols: small/fast, medium, large/slow, and vary alpha and blur.
If you want, I can:
- produce step-by-step screenshots,
- provide a ready-to-import .fla/.an file structure with a Comet symbol,
- or give a complete sample HTML5 Canvas createjs snippet that spawns multiple animated comets.
