About
Junkyard Bash is a physics based racing game for 1-4 people where players race through a scrappy junkyard full of traps and junk.
This was the first project we did at Futuregames in two weeks where our theme was Physics and Goofiness. So we made a racing game with goofy characters and where the vehicles were all driven by physics.
Game Play Programming
I made all the Game Play Programming such as Input Handling, the Camera and the different Physics-Based Vehicles that are made completely from Scratch.

Back-End Programming
PlayerController, GameMode & GameInstance
I made all the Back-End Programming such as Character Select Screen, Checkpoints, State Machine and the different Multiplayer Setup with Spawning, setting the cameras, clearing up Player Controllers etc.
You can play the game with 1-4 players but I made it comfortable to pickup and play so for example controller 1 and controller 4 could join a game and it would be a 2 player game with the split screen adjusted for the amount of players joined.

States
I make good use of States to determine where in the game the player is, for example At Menu, At Sub Menu or At Race, depending on which the Input could execute different things. There is so much more I could write about the Back-End but for readabilities sake I'm gonna present the most notable below.
Input & Use of States
Level Streaming
The game's level is split up into several sub levels so each designer and artist could work on different one without conflicts. The Main menu uses the same level to make the transition from Character Selection Screen to Race quick.
After the Levels have been loaded it checks what State the Game is in, for example if it was AtIntroLogos it means the game has been just Booted, If it was Debugging then it will call Debugging and spawn the characters that's been chosen to debug with right away.
