Tank-Game

You and a friend fight in an arena to the best of 3! Player 1 uses WASD to move and F to shoot and player 2 uses IJKL to move and H to shoot.

Game States:

Intro Screen:

• Show Instructions
• Start Button (Start game)
• Quit Button (Exit game)

Game Play:

• Show predetermined map
• Give each user a score of 0
• Every hit to the other player increases the other's score by one
• Each hit moves hit player to opposite side of the screen from attacker
• First to 3 points wins (shows winner screen when player hits 3 points)

Game Over:

• Declares winner

• Shows play again btn (starts game over)

• Quit button shown

  Player win screen:

• Shows "Player [winner] Wins!" in text box

• Play again button (starts from Game Play screen)

• Quit button (goes to home screen)

Sprites:

Player1:

• User-controlled green tank sprite

• Rotate tank with A and D

• Move forward with W

• Backwards in facing direction with S

• Shoots with F in the directions the barrel is facing

• Cant pass through outer barrier or cover barriers

• Starts on left screen

  Player2:

• User-controlled red tank sprite

• Rotate tank with J and L

• Move forward with I

• Shoots with H in the direction the barrel is facing

• Cant pass through outer barrier or cover barriers

• Starts on right screen

  Bullets:

• Shoots in direction of barrel on either tank sprite

• if bullet on one player hits other player while their bullet is in motion, it resets the hit players bullet as well - Gets rid of simultaneous hits

• Sound effects from firing of bullet and colliding of bullet

  Barriers:

• Stops bullets

• Stops tank movement

• Keeps sprites from moving off the screen or through cover barriers

• Placed in predetermined locations

• Moves tank sprites to keep from going through barriers

  Player win screen:

• Shows "Player [winner] Wins!" in text box

• Play again button (starts from Game Play screen)

• Quit button (goes to home screen)

UI Components

• Background - Rocky - Contrasts well with tanks and barriers
• LblScore - Adds a score for each tank - Adds by one for each hit on the opposing tank -
• LblStart - Starts game when clicked - Appears on title screen and win screen
• LblQuit - Quit the entire game when clicked - Appears on title screen and win screen

Reflection

Goals

• To create a simple yet elegant 2d tank game
• Figure out how to code barriers
• Gain a better understanding for the SimpleGE game engine
• Make a game compatible with the class arcade machine

Technologies and techniques used

• Referenced professor's code in multiple instances such as bullet behaviors and creating working sprites and barriers
• SimpleGE and Pygame

My Process

I learned that such a simple looking game on the outside can be very challenging and complex to make

• It makes you appreciate how hard people work on games and how complex their code must be

I got stuck when trying to create barriers

• It is difficult to check the angle of the tank sprite while colliding with a barrier
• Any angle outside of a 45 degree span of a direction would confuse the collision point of the barrier
• Solution: Create 4 different barrier sprites to isolate the collision checking for the sprite
  • Each barrier side will only check one side for collision, giving a whole 180 degree angle for the tank to collide with

I would like to decorate the home screen and win screens a bit

• Plain black with white buttons
• Could be more decorative

I would take more breaks while coding

• A lot of the struggle in coding barriers came from overthinking about the problem
• Breaks would allow me to think in much more simple terms to help me solve the problem

I did not allow for a custom map selection in my final product

• My original game document called for that
• Put much more focus on mechanics than bells and whistles

Each class period I would have at least one new feature added to my game

• This allowed me to stay on track and complete my game on a good timeline
• One week would be focused on sprites and another focused on barriers, for example
