Clean Input Debugger Tool for Unity Mobile Devs

After slamming my head into the wall for the 37th time while debugging mobile input, I decided I was done. I needed something dead simple that could just show me what the hell the player was actually doing—touches, key presses, input phases, whatever.

So I built one. And now it’s up for anyone else dealing with the same nonsense.

🧰 What It Is

Input Debugger is a drop-in prefab that logs your mobile touch input and keyboard input in real time. It’s a clean, lightweight tool built specifically for Unity URP (2022.3.6f1+) and designed to just work—no fluff, no bulky setup.

✅ Shows touches (with position, phase, and delta)
✅ Logs key presses from a configurable list
✅ Displays in UI or logs to console (toggleable)
✅ URP-ready, mobile-tested, touch-safe
✅ One script, one prefab, one job done right

🧪 Why I Built This

When you're developing mobile-first, Unity makes it surprisingly annoying to debug touch input. Half the time you're just guessing if a tap even registered. Unity's Input Debugger (the window) isn't much help in builds, and the new Input System? Great—but overkill for quick prototyping or small tools.

So I made a barebones visual logger that gives clear, actionable feedback on input as you play—especially useful for:

• 🔧 Debug builds during mobile testing

• 🧪 QA workflows

• 📱 Fast prototypes or UI testing

• 👀 Showing clients/devs what’s being triggered

💡 How to Use It

1. Import the .unitypackage

2. Drag the InputDebuggerCanvas prefab into your scene

3. Press Play

4. Profit (or at least, sanity)

Want console logs too? Flip a checkbox. Want to change which keys to watch? Edit a list. Done.

🧼 Clean Code Promise

I made this for people like me—who hate messy scripts, unfinished junk, and guessing games.
The code is clean. Commented. Easy to tweak. No trash or "TODO" comments.

🔜 What’s Next?

If folks find this useful, I might add:

• Toggle key

• Auto-hide mode

• Color-coded phases

• Touch trails (visual feedback for swipes)

Let me know if you use it. Or break it. Or improve it. I’ll gladly update the package with fixes or extras if it helps other devs save time and debug faster.

Built on Unity 2022.3.6f1, URP, tested on Galaxy S23 FE.
No BS, no license drama. Use it however you want.
