Captain Stealth

2D Top-down stealth game developed in C++. Switch between two characters to work together to escape the prison. As the technical lead of a team of 4 programmers, I was responsible for designing and implementing the core architecture of the game. Download and play it here (installer).

Theme

Prison break.

Gameplay

• Get to the end of the level while avoiding detection by the guards.
• Switch between two characters.
• Players need to find keys to open the door to the next area.
• Hide in vents to temporarily evade guards
• Interact with objects to distract guards.
• Enter stealth mode to sneak past guards.

Architecture and Features

I was responsible for building the following systems.

Component System

Really simple component based system inspired by Unity’s scripting system (MonoBehaviour). At this point in time I did not have a clear idea on what Entity Component Systems (ECS) really were.

Hence, I decided to go with a inheritance based component system. Components inherit from a base component class, and override behaviours on functions such as Start(), Update(), etc. As a side note, the CRTP C++ pattern was used for deep cloning.

Scripting

Scripting is a loose term here, mainly used to seperate engine and gameplay code. Scripts are functionally identical to components, just with a different class name and updated in a seperate loop.

Audio

Fmod.

Game State Manager

Simple GSM using function pointers to invoke behaviours for each scene.

Message Bus

Simple Event System using listeners and inheritance.

Level Editor

Edits tile maps and saves them on the disk.

Tile Map

Tile map is tile map.

Camera

View Matrix does view matrix things.

Graphics

Simple wrapper that calls AlphaEngine rendering code. All graphics in the game uses 2D quads for rendering.

Other Features

These are some of the other features that were not implemented by me.

• Pathfinding
• Physics
