Bounce

A 2D clicking game built in C++ with Raylib. Click the right balls, avoid the wrong ones, and beat the clock.

---

Gameplay

You have 30 seconds. Colored balls appear and disappear on screen:

Ball Color	Effect
🟢 Green	+1 point
🟡 Gold	+2 points
🔴 Red	-1 point

Click as many green and gold balls as you can. Avoid red ones. The game gets harder over time — balls flash faster as the clock runs down.

Controls: Mouse click only. Press R to restart after game over.

Features

• Game state machine — clean transitions between START, PLAYING, and GAME OVER screens
• Dynamic difficulty — three phases that progressively shorten ball visibility duration
• Random spawning with overlap prevention — balls reposition without clipping into each other
• Frame-rate independent timing — smooth behavior at any FPS using GetFrameTime()
• Score feedback — point value displayed on click at ball position
• OOP design — Ball and Game classes encapsulating state, logic, and rendering

Ball class manages position, radius, color, score value, active state, and drawing.

Game class owns the ball pool, score, elapsed time, game state, and difficulty phase logic.

Building

Requirements

• C++ compiler (g++15 recommended)
• Raylib installed
• Make
• pkg-config

Linux / macOS

make run

Technical Highlights

• Custom rand<T>() wrapper around mt19937 for clean random number generation
• Collision detection using Raylib's CheckCollisionCircles and CheckCollisionPointCircle
• Object pooling pattern — 10 pre-allocated Ball objects reused across rounds
• Three-phase difficulty engine adjusting show and hidden timers dynamically
