Aim Up (Reaction Race)

A lightweight aim + reaction training web app.

Click the moving target as quickly and accurately as you can. The app tracks your accuracy, misses, reaction time, and precision (how close your click was to the target center). You can run it in a normal 2D grid view or switch to a 3D arena.

• Moving target practice (2D)
• 3D arena view (3D)
• Modes

How to Run

Option A: Open the file

Open index.html in your browser.

Option B: Run a local server (recommended)

Some browsers restrict certain features when opening files directly. A simple local server avoids that.

Python:

python -m http.server 5173

Then visit:

• http://localhost:5173

How to Play

• Click Start to begin.
• Click the dot/target as it appears.
• Clicking anywhere else counts as a miss.
• Choose a Race Mode to play for a click count or a time limit.
• Use the sliders to adjust Dot Speed and Dot Size.
• Change Dot Color and Dot Shape to vary visibility.
• Use Arena View to toggle the 3D arena.

Project Structure

• index.html — UI markup
• styles.css — styling (responsive layout included)
• script.js — game logic + stats + 2D/3D/WebGL target handling
