EVIL ROBOTS: CITY INVASION

As this was one of my first experiences creating a game, I focused on level design and game mechanics for my game, Evil Robots: City Invasion. The game begins in the outskirts of the city and progresses through to the final level set in a carpark where the player fights the boss enemy. I chose the carpark as the final location because it offered gameplay opportunities for the player to approach the enemy from different directions while providing cover to protect themselves.

​

The win condition of the game is to defeat the final boss and save the city, however if the player loses all five lives they will be presented with a "Game Over" screen. To keep the gameplay engaging, I included two enemy types that get progressively harder to defeat, with each new type introduced at each level. Below are the stats I chose for the player and various enemy types.

​

• Player:

  • Begins with 1000 health and 5 lives

  • Each bullet does 50 damage

  • Each mine does 100 damage to enemies

• Soldier enemy type:

  • Bullet does 25 damage

  • Health value of 400

  • Explodes upon death, doing 100 damage to the player if within range

• Turret enemy type:

  • Bullet does 50 damage

  • Health value of 500

  • Explodes upon death, doing 100 damage to the player if within range

• Boss enemy type:

  • Does not shoot the player directly

  • Spawns smaller soldier enemies with 10 health every 5 seconds

  • Has a health value of 1000

​

During the development process, I faced a few challenges that required some creative problem-solving. One recurring issue was the disappearance of scripts from the soldier and soldier bullet prefabs. I discovered that removing and reattaching the component solved the problem. For the proximity mines, I struggled with getting them to damage both players and enemies. To resolve this, I created a trigger sphere around the explosion prefab and attached a script to it, specifying the damage and lifespan. Using the OnTriggerStay function, I made it so the script would call the TakeDamage method for any game object with the player or enemy tag that collided with the sphere. Additionally, implementing a game over screen proved to be tricky. I needed to show the death of the player's droid before transitioning to the "Game Over" scene. To achieve this, I created a separate function that, when called by the PlayerHealth script, set a boolean to true. This boolean initiated a timer that, when it reached zero, called the method to change the scene.

Creating Evil Robots: City Invasion was an interesting and challenging experience. I faced a number of difficulties and had to overcome many obstacles along the way. However, my passion for the project kept me motivated and I felt a great sense of accomplishment when I finally completed the game.
