Foil Effect Plugin - Construct 3

✨ I made a foil effect for my game and decided to share

⚠️ This is a Construct 3 effect addon — it only works with the Construct 3 game engine.

Add that premium trading card shine to any sprite. Cards, UI buttons, loot drops, buildings, resources, characters. If it's a sprite, it can shimmer.

🎮 Interactive Demo

The playable demo above is a real-time parameter tester. Every slider value you see matches exactly what you'll use in Construct 3. Find your perfect look, note the numbers, and copy them directly into your project.

🚀 Features

6 Noise Pattern Types

• Simplex — smooth, organic flow
• Value — fastest performance
• Worley — cellular/bubble patterns
• Voronoi — crystalline edges
• Turbulence — fiery, chaotic
• Cellular — complex cell structures

Dual Color Modes

• 🌈 Rainbow Mode — full spectrum holographic
• 🎨 Custom Gradient — pick any two colors (gold/pink, cyan/purple, etc.). Not included in the demo, but you can see example colors below and find random combinations using the "Random Colors" button.

Full Control

• Intensity — subtle sheen to maximum bling
• Speed — static (0) to fast-moving animation
• Scale — smooth gradients to visible noise texture

❓ Why Free?

I searched for this effect in Construct 3 and couldn't find it. Barely found equivalents for other engines either. So I made it myself for my own game and figured the Construct community (something I am actively a part of) deserves nice things too.

🦝 See It In Action

I use this effect in my own game for buildings, resources, buttons, and loot drops, not just cards!

Note: Currently, only Demo #1 is available.
You'll be able to see the Foil Effect in action when Demo #2 or the full game is released!

📝 Disclaimers

• Construct 3 only — this addon does not work with Unity, Godot, Unreal, or any other engine. Construct 3 exclusively.
• Vibe coded — I'm not a shader expert. This was built through experimentation and iteration until it looked and felt right.
• Marketing exercise — honestly, this page is partly me practicing my marketing skills. I could have just dropped an empty half-assed page with a link to download, but I wanted to exercise my sales "bone" and make something that is not only useful, but very friendly and understandable.
