2D Trail Effect (Pro)

Want to make your dashes look cooler, attacks fancier, or projectiles more dynamic? This tool makes it easy and super customisable!

🚀 Why Use This Tool?

✅ Quick Setup: Just 2 simple steps (technically 1), and you're ready to start spawning different types of trails.

✅ Accurate Gaps: Trail positions are precisely calculated to stay consistent even at inconsistent frame rates.

✅ Fully Customisable: Control colours, sizes, lifespans, sprites, spawn intervals, easing, and more.

Check out the example scene and documentation (available in English & Traditional Chinese) to get started.

==============================================

🆓 What You Get in both the free and Pro version:

🎯 Easy trail spawning with 1 line of code

⚙️ Customise order in layer, gradient colours, size settings, lifespan, gap interval condition

🌀 4 built-in easing equations (Sine, Exponential, Circle, Elastic) that you can also use in your own project

🧠 Accurate trail spacing even with inconsistent frame rate

🔍 Debugging tools that display trail info in the inspector and the hierarchy

🔒 What You Unlock in the Pro version:

🔁 Profiles: Create profiles and reuse trail settings, saving your time copying and pasting. Switch profiles at runtime, allowing a game object to easily spawn different types of trails.

🎨 Override Sprite Colour: Choose to fully override or just tint the sprite.

🖼️ Custom Sprites: Use specific trail sprites, cycle or randomise them, not just limited to the sprite of the game object.

📈 Animation Curve: Full control over scale changes beyond easing presets.

💥 Physics Trails: Enable collisions for interactive trail effects, they are not just visual effects anymore!

📣 Events: Subscribe to profile change, trail start or stop, object init or destroy events, and more.

🔧 Extension Methods: Cleaner and shorter code for spawning and managing trails.

🔬 Experimental features in the Pro version:

🤖 Auto Start/Stop: Trails can automatically start and stop based on speed, time, or distance, no code is needed, unless you want...

🧩 Custom Conditions: Write your own auto-start and stop logic in case the built in ones don't fit.

==============================================

This is the Pro version. The Free version gives you the core features with basic customisations, whereas this version unlocks the full toolkit.
