Asteroids game implemented in Unity

asteroids-game's Issues

Teleport to other side of the screen

• When a game actor crosses a side of the screen, it will appear on the opposite side.
• A game actor can be:
  - Player spaceship
  - Asteroid
  - Bullets
  - Enemy spaceship

Player death

• The player dies when it is hit by an enemy or bullets
• When it dies it will disappear from the screen for a while and reappear (possibly blinking while returning to the game) at the center.
• It will always receive points
• It will decrease one life from its current life amount
• When the life amount achieves zero, it is game over

Fire bullets when Ctrl key pressing

• The bullets should be pooled.
• They return to their pool when hit target or after some seconds without hitting anything.
• They aways are spawned in front of the ship

Asteroids behavior

• Spawn initial asteroids at different places on the screen
• They will move in a constant direction (change this behavior later, if there is time)

Hit enemy with bullets

• When an asteroid is hit, it will return to its pool. If it is the bigger asteroid it will also spawn small ones in different directions.
• If an asteroid hits the player, it will die.
• If an enemy is a spaceship, it will just return to its pool
• Every enemy gives a specific amount of point to the player when dying

Sound control

Add and control music and sound effects

Score system

• Implement UI
• Increase player score every time it hits an enemy, including when it hits with its spaceship

Decouple Speed control from Movement control

Currently, speed and movement control are in the same place. Mostly game objects only need motion control. Separate the speed control to a difference Component.

Game over and game start

• On game start, all game actors are spawned
• On game over, the scene is loaded again
• There will be a UI for game start and over.

Destroy effects

Implement visual effects of objects destroying when they die.

Implement rotation according to keyboard horizontal pressing

Make spaceship rotate to the direction of horizontal key pressing

Spaceship movement

• The ship moves always towards the direction it is pointing.
• When pressing the Up key the ship will receive a force towards its direction
• If It does not receive movement it will gradually lose speed until it stops.
• When holding the Up key it will increase its speed until a maximum speed when it stays at this maximum speed until the player releases the button.

Enemy spaceship behavior

• There is at least one type of enemy spaceship
• It will shoot bullets in different directions at the same time while moving on the screen
• There may also have an enemy who shoots towards the player's position
