Overview

500 spaceship entities, 4 planets, thousands of bullets with solid performance

• Spaceship Generation: Spaceships are dynamically spawned in large quantities. The number of spaceships is customizable within the editor.
• Spaceship Behavior:
  • Upon spawning, each spaceship identifies the nearest planet.
  • The spaceship then proceeds towards that planet.
  • As the spaceship approaches a specified distance from the planet, it begins firing at it.
  • Once the spaceship is in close proximity to the planet, it reverses its course and repeats the entire process.
• Camera Interaction:
  • Initially, the camera automatically tracks one randomly selected spaceship.
• Players can switch the camera's focus to another spaceship by pressing the Space key.
