2D Ghost Trail Spawner - Unity

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.
• 🤖 Auto Start/Stop: Trails can automatically start and stop based on speed, time, or distance, no code is needed. Of course, your can your own auto-start and stop logic in case the built in ones don't fit.
• 💥 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:

• 💨 Trail Movement: The trail can move to a specific direction or a random direction within a range.

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