SNAKE - Add different game modes

[neur0n-7]

Game has only one mode

Description:

• What should happen:

  • We can modify the game mode in settings. For example, the Google Snake version has hundreds of possible ways you can play the game

    

  • Potential game modes:

    • Candied Apples: After every apple that you eat, your speed increases.
    • Brick Drop: Obstacles randomly appear on the grid, making the game harder. (If we have enough time)
    • Golden Apples: Yellow apples occasionally appear on the course, which give you triple points. (If we have enough time)

• What actually happens: Game has only the game modes of classic and "walls disabled".

• Steps to reproduce: Launch the game then select settings

Acceptance Criteria:

• We can go into settings and modify the game setting.
• Add at least Candied Apples in addition to the Classic game mode.
• Test cases for Candied Apples:
  • Make sure snake speed increases after each apple.

Debug Strategy:

• For Candied Apples game mode:
  • Take the game speed given by the settings selection and increase the variable every time an apple is collected.
  • Optional: show a multiplier counter, starting at 1x and grows continuously

This was by far our biggest change.

For Candied Apples, we had a variable representing acceleration, that would let the snake become exponentially faster every time it ate an apple.

Fruit Frenzy was more complex. We at first had an issue where the golden apple phased through the snake, but then we fixed it. Essentially, it has a random x velocity and y velocity on spawn (40% chance). If it hits something vertically or horizontally, then we reverse the x velocity or y velocity.

Also, we originally planned to have the golden apple be 3 points. But when we played the actual game, 3 points felt unrewarding. We made it 10 points to make it worth it to spend your time hunting down that gosh darn apple.
