Game Overview

BumperCars is an example of a small mini-game using vehicles.

It contains the basic elements for creating mini-games, such as player equipment restrictions, vehicle management, Ready Up, game status, and UI display.

Main Topics

• Game initialization, AutoSpawn settings, and InteractPoint control at OnGameModeStarted.
• Remove weapon and limit fire input at OnPlayerDeployed.
• Add spawned vehicles to game management at OnVehicleSpawned.
• Receive Ready Up and debug operations at OnPlayerInteract.
• Track progress with GameState and HoH_GameHandler.
• Manage the state of each player at PlayerProfile.
• Manage countdown, winner display, and scoreboard in UI class.

Reading Order

1. Check entrance events

First, read only the event function at the beginning of the file.

OnGameModeStarted, OnPlayerDeployed, OnVehicleSpawned, OnPlayerInteract are the entrances to game progress.

2. Check GameState

GameState represents what stage this mode is currently in.

Is it during Ready Up, during the starting countdown, or during the match? Looking here tells you which state each event should be allowed to pass through.

3. Check PlayerProfile

Each player's state is collected in PlayerProfile.

In games where players join, leave, die, or respawn, collecting player information in one place makes it easier to track.

Small Tips

Importantly, OnPlayerDeployed removes the weapon and limits fire input.

In vehicle mini-games, if normal FPS operations remain, the gameplay will be broken. It is safer to first erase inputs and equipment that are not needed for the mode.

Conclusion

BumperCars is a sample that shows the skeleton of the mini-game Portal mode.

It is worth reading when you want to learn about vehicles, Ready Up, state management, UI, and player management all at once.
