Pause Game for Multiplayer , Video Animation

PAUSE GAME

How I did it:

Server-Client Signal System: Players send a pause request to the server using C# network messages. The server validates the request and broadcasts it to all connected clients in real-time.
Voting UI: Designed a dynamic UI showing all players and their votes, including a live vote tally, so everyone can track progress toward pausing.
Majority Decision Logic: The server counts votes, freezes the game state once the majority threshold is reached, and prevents any player from bypassing the pause or resume process.
Real-Time Feedback: Implemented instant vote updates.
Block Manager UI: Implemented a UI blocking system to prevent the pause menu from closing or being interrupted when players interact with other in-game actions. This ensures the pause process remains stable and user-friendly, even during concurrent interactions.

VIDEO ANIMATION

Video files are stored in the Resources folder, and I wrote a system that searches for videos containing the word “Landing” and automatically assigns them to the corresponding player (e.g., CNSA, NASA).
Each player has their own color and assigned video.

HandleResumeRequestServer

Purpose: Processes a player’s request to resume the game after a pause.

How it works:

Receives a request from a client when a player wants to resume gameplay.
Records the player’s vote and checks whether the majority has agreed to resume.
If the majority is reached, it triggers the game to resume for all players.

VoteResumeServerRpc

Purpose: Handles individual player votes for resuming the game.

How it works:

Each player’s vote is sent to the server in real-time.
Updates the vote tally and propagates changes to all clients.
Provides immediate feedback to players via UI updates, keeping everyone informed about vote progress.

Skills & Impact

Networking & Server-Client Synchronization: Implemented server-authoritative control using ServerRpc, ensuring consistent game state and preventing premature game resumption.

Multiplayer Vote Tracking: Managed real-time voting logic for pause/resume, updating vote tallies and UI dynamically across all clients.

UI Feedback & Player Engagement: Designed responsive UI to display live vote counts and feedback, keeping all players informed.

Technical Skills: C#, Unity UI, event-driven design, networked game logic, multiplayer system design.

Character System & AI

Unreal Enigne / Blueprints:

Combat and Shooting
- Shooting, aiming, damage, and character/AI reactions
Crouch, Climb, Stealth, Locomotion
- Full control and smooth character movement
Animations and Motion Capture
- Sign language for the protagonist, cutscenes, and short films
Dialogue and RPG System
- Player choices affect story and NPC/AI reactions
- Created interactive dialogues and NPC responses based on player decisions
Character AI
- Patrolling, responding to player crimes, attacking, conversing, and performing tasks
- Behavior Trees control NPC decision-making based on environment, player interactions, and situational context
- Day/Night NPC awareness: NPCs see the player only at close range at night, but detect from a distance during the day
Camera System
- Area patrol and environmental interaction
Puzzles and Interactive Mechanics
- Require logical thinking and strategy from the player

C++ – Drone AI System

Patrols environment when the player is not visible
Searches for a few seconds if the player disappears from sight, then returns to normal patrol
Triggers alarm and shoots when the player is detected

Technologies & Tools

Unreal Engine 5 (Blueprints & C++) – all gameplay logic and AI systems
Motion Capture – animations for movement and sign language

Results / Achievements
- Comprehensive character system with wide range of movement, combat, and interactions
- Dynamic AI reacting to player actions and decisions within the RPG system
- Smooth sign language animations integrated into cutscenes
- Game prototype combining RPG, stealth, puzzles, and combat systems, entirely created in Blueprints

Patrol Drone AI

Unreal Engine / C++

I created drone behavior in the game based on patrol logic and player detection.
I implemented a decision tree controlling the drone's behavior:
- Player detected → drone interrupts patrol, stops, and shoots.
- No player in sight → drone returns to patrol points.
This allows the drone to react dynamically, making its behavior both realistic and predictable for the player.

NPC Behavior (Behavior Trees & AI Systems)

NPC AI: I designed neutral and hostile NPCs that patrol the environment, respond to the player’s presence, and interact with their surroundings.
Behavior Trees: Control NPC decision-making based on environmental conditions, player interactions, and situational context, enabling complex, adaptive behaviors in real time.
Interactive Reactions: NPCs can respond to player actions in various ways, such as evading, attacking, or engaging in dialogue, enhancing game immersion.

Wingman

Unity / C#

I was responsible for several key game elements: audio, UI, and plane control.

Audio Design – created and implemented sound effects and the game’s music track.
Checkpoint Development – developed a system of checkpoints that the player must pass through, including collision detection and level progression.
Plane Movement UI – designed the interface for controlling the plane, including:
- Plane rotation and flips in response to player input.
- Touchscreen button layout that is intuitive for the player.

Montion Capture

I am creating a character of a young girl from scratch, from the 3D model to animations in sign language. The project is still in development – I am refining the details of hand movements and facial expressions to make the sign language fully natural and readable

What has been done

3D character modeling and skeleton rigging in Blender.
Initial motion capture recordings using Rokoko integrated for sign language gestures.
Basic character animations and interactions with the environment.

Work in progress

Refining facial expressions to realistically convey emotions and intentions.
Improving hand and arm movements to ensure sign language gestures are accurate and natural.
Optimizing animations for smoothness and synchronization with Rokoko motion capture data.

Project goal
- Create a realistic animation of a character using sign language.
- Showcase the process of motion capture and character animation from scratch using Rokoko → Blender workflow.
- Final product: Animations for a December calendar — not primarily for a game, though the character could potentially be used in a game in the future.
