2D Chicken Shooting

I have developed multiple 2D shooting games, including chicken shooting and multi-level gameplay. Each level is designed with new challenges and mechanics, providing players with an immersive and exciting experience.

Challenges

Creating an engaging 2D shooting game requires more than just fast-paced action; it involves solving various technical and design challenges to ensure smooth gameplay and replay value. From handling multiple bullets efficiently to keeping the visuals dynamic, every aspect needs careful consideration. The goal was to make the game feel fluid, visually appealing, and challenging without overwhelming the player. Here are some key challenges encountered during development and the solutions implemented to overcome them.

  • If too many bullets appear on the screen at the same time, collision detection can slow down, causing FPS drops
  • 2D shooting games can feel visually flat and repetitive if the background remains static.
  • Simple shooting mechanics can feel repetitive, so balancing weapon upgrades and power-ups was a challenge.
  • If enemies follow fixed patterns, the game becomes predictable.
  • If the player or bullets move outside the screen, it can cause gameplay issues.

Solutions

In 2D shooting games, maintaining smooth performance, engaging visuals, and dynamic gameplay is crucial for an immersive experience. Without proper optimization, issues like frame rate drops, repetitive gameplay, and predictable enemy patterns can negatively impact player enjoyment. To tackle these challenges, various techniques were implemented to enhance performance, improve mechanics, and ensure a balanced and engaging experience.

To optimize bullet collision and performance, an object pooling technique was implemented to reuse bullets instead of continuously instantiating and destroying them. This significantly reduced memory allocation and improved FPS stability. Additionally, layer-based collision and raycasting were used to make collision detection more efficient, preventing unnecessary physics calculations and ensuring smooth gameplay even during intense shooting sequences.

To enhance the visual appeal and make the game world feel dynamic, a parallax scrolling system was introduced. Multiple background layers were designed to move at different speeds, creating a sense of depth despite the 2D environment. This helped prevent visual monotony and added an engaging, immersive experience. Alongside this, a balanced weapon and power-up system was developed using Scriptable Objects, allowing for easy addition of new weapons with distinct properties. Cooldown mechanics and damage variations were fine-tuned to ensure fair yet exciting gameplay progression.

Enemy spawning and behavior were designed to be unpredictable, preventing repetitive gameplay. A randomized spawning system was implemented, ensuring that enemy types, speeds, and attack patterns varied in every session. To maintain smooth camera movement and avoid off-screen gameplay issues, camera boundaries were set, and a bullet destruction system was introduced. This ensured that bullets and enemies that moved beyond the screen were removed efficiently, preventing unnecessary resource usage and maintaining optimal game performance.
