Chasing-Enemy: Dynamic Obstacles & Items

A survival game built with Pygame, where you must outmaneuver a sword-wielding enemy while navigating dynamic obstacles, collecting coins, and avoiding bombs. The goal is simple: survive as long as possible while maximizing your score.

🎮 Gameplay Overview

You play as a terrified character constantly chased by a dangerous enemy.

Use arrow keys (or WASD) to move around the screen.

Survive as long as you can while dodging:

Obstacles that spawn dynamically and block paths.

A relentless enemy wielding a sword.

Bombs that penalize your score if collected.

Collect coins for bonus points.

The longer you survive, the higher your survival score.

✨ Features Player

Smooth movement with collision detection.

Always confined within the game window.

Enemy

Constantly pursues the player using a basic AI.

Adjusts pathfinding slightly when blocked by obstacles.

Sword animation dynamically points toward the player.

Items

Coins (+5 points): Spawn randomly, despawn after 15s.

Bombs (-5 points): Trap items that decrease your score.

Smart spawn system ensures items don’t appear too close to the player or inside obstacles.

Obstacles

Dynamic rectangular blocks appear randomly.

Despawn after 10s.

Maximum of 8 obstacles at any time.

Carefully placed to avoid unfair spawns on top of the player.

Scoring System

Survival Time: 1 point per second survived.

Item Score: Collect coins and avoid bombs.

Total Score = Survival Time × Multiplier + Item Score.
