🚀 Getting Started

This project contains submodules and requires --recurse-submodules when cloning:

git clone --recurse-submodules https://github.com/JanSeliv/Bomber.git

If already cloned without submodules, you'll find empty folders in Bomber\Plugins and error on project startup. To download submodules separately, run:

git submodule update --init --recursive

🛠 Key Features

This project could be useful for learners, demonstrating next features:

• Multiplayer
• Procedurally generated playfield
• Challenging AI
• Enhanced Input
• Modular Game Features
• Complex cinematics (Level Sequences)
• Data-Driven Design (Data Assets, Data Tables, Data Registries, see below)

Despite this project is fully written in C++, it's extremely blueprint-friendly:

• Data-Driven Design: No hardcoded values. All data can be tweaked via Data Assets in editor as well as accessed in blueprints [doc].
• Fully Exposed: Every class, property, and function is exposed to Blueprints allowing for heavy changes the logic with no code.
• Well-Commented: Every class, property and function is well-commented for easy understanding.
• Utility Libraries: Core static functions are accessible globally like Cell Utils [doc]. See more in the Source\UtilityLibraries folder.

Next plugins were developed for this project, but could be useful for other developers:

• ⚙️ Settings Widget Constructor
• 🔄 Pool Manager
• 🎭 Morphs Player
• ƒ Function Picker
• >_ Meta Cheat Manager

🎮 Overview

The level camera that moves and zooms lens depending on the distance between players:

Level actors

• Items that affect the abilities of a player during gameplay:

Skate: Increase the movement speed of the character.

Bomb: Increase the number of bombs that can be set at one time.

Fire: Increase the bomb blast radius.

• Bombs: are left by the character to destroy the level actors. Triggers other bombs and prevents players from moving through the bomb after it has been left behind.
• Walls: are not destroyed by a bomb explosion and stop the explosion.
• Boxes on destruction with some chances spawn an item.
• Players and AI - characters whose goal is to remain the last survivor for the win.

Game interface

The number of items that are shown at the left side of the player’s avatar, the timer that is placed under and at the right side is shown the number of alive players:

The game menu is shown the result of the games match (win, lose, draw). If the match has not yet finished, it could be minimized or opened out by ESC button in order to continue watching the game or restart the play, or to return to the main menu:

• Shows the win notification when there is one character left:

• Shows the draw when the last players are killed at the same time or at the end of game timer:

• Shows the lose when the player was killed:

Procedural generation

• Symmetrical regeneration for each new game:

• Scaling sides sizes in the editor or sizes selection in the start menu:

Cells Data Structure

• Actors snapping to the center of the cell:

• Searching of the nearest cell to an actor:

The Map Component

These components manage their owners and update this level actors in case of any changes on the map that allow to:

• Prepare in advance the level actors in the editor time:

(Dragged from the Content Browser the wall, the character, the item, the box, and the bomb, that correctly exploded due to Maps Components)

• Free location and rotation of the level map in the editor time:

Artificial Intelligence

Bots behave like players with no use of the Unreal NavMesh:

• They can find items even around the corners and are able to manage their priorities correctly:

(There are three items: A - the nearest under the bomb explosion, B - the item that is placed around the corner near the enemy character. C - the farthest safe item. The bot does not risk and chooses to move to the C)

• Emergency Priority Change:

(The bot runs for the item, the player otherwise set the bomb. Meanwhile, the bot changes direction and runs off the bomb)

• The bots even survive through in the midst of explosions:

• The editor preview visualization for selected bot automatically updates upon any changes on the map including addition from the Content Browser or drag-and-drop.

Where is :

Green +: a safe crossway.

Red +: crossway which has at least one enemy character.

Yellow F: filtered cells for moving.

Grey Х: the selected cell on which the bot moves to.
