Player movement forms the foundation of the gameplay experience, allowing players to navigate the environment, interact with vehicles, and engage in the game's core systems. Player movement is integral to transitioning between on-foot exploration and vehicle-based gameplay. This feature includes walking, running, interacting with objects (e.g., vehicles), and animations for entering/exiting vehicles.
The player movement system is implemented using Unreal Engine's Character Class, which provides built-in tools for character locomotion and physics-based interactions. Locomotion Configuring inputs for movement to ensure responsiveness and accessibility, Using a blend space to dynamically swich between idle., walking and running animations based on the players speed. Interaction with Vehicles Interaction are triggered with collision boxes when the player is near the vehicle door. Using a animation montage when the player interacts with the vehicle e.g. opening the door. Swapping the input controls from the player character to the vehicle actor once the interaction is complete.
The design of the player movement system focuses on delivering fluidity, realism, and functionality to ensure the player feels connected to the game world.

Vehicles are the backbone of the game, serving as the primary tool for players to immerse themselves in the game world and complete their objectives. Each vehicle is equipped with a range of dynamic components and interactive features, designed to enhance realism and gameplay functionality. These include togglable indicators, functioning headlights, responsive door animations, and physics-driven driving mechanics.
All vehicles inherit from a single base class, enabling shared functionality such as lights, doors, and driving systems.
Every vehicle feature is designed to reinforce immersion, their was also a heavy focus on scalability through the modular vehicle framework which allows for the addition of new vehicles or features without significant rework. For example, new car models can inherit core systems while introducing unique capabilities.

Job preparation is a critical system that ensures smooth gameplay flow by dynamically spawning and assigning passengers to the player. This feature prevents invalid spawn points, generates randomized passenger data, and presents a clear UI for players to accept or decline jobs, adding realism and interactivity. When the player is without a passenger, the system spawns a new passenger at a valid location along predefined pathways. Passengers are dynamically generated with attributes like name, fare, and difficulty level. A seamless UI system introduces the job to the player, providing all necessary details, and allows the player to either accept or decline the request.
Passenger Spawning - When no passenger exists, a passenger actor is spawned using a predefined class. - The mesh initially set to be invisible and non collatable. - A random spawn location is selected from a designated pathway collision boxes. - Collision boxes validate the location using a Boolean flag. if invalid the, location is reset until valid. Passenger Attributes - Upon spawning, passenger's attributes such as name, fare, difficulty and time estimates are generated and assigned. Job UI Prompt - Once a valid location is confirmed a UI element appears on the screen including, passengers name, estimated fare. time to pickup and drop off along side the jobs difficulty level. Job Handling - Players can then choose to accept or decline the job, if declined the passenger actor is destroyed and the system restarts the loop to generate a new passenger.
By using collision pathway boxes and continuous checks, the system ensures no passenger spawns in invalid areas for example in the middle of roads or other obstacles. This avoids immersion-breaking glitches. Randomized passenger attributes add variety, making each job unique. Including factors like difficulty level and time constraints allows for scalability in gameplay. Players can make strategic decisions based on their preferences and vehicle capabilities.

The job acceptance feature is a crucial part of the gameplay loop that allows players to decide whether to accept or decline a passenger’s request. Upon accepting a job a pointer system guides the player to the passenger's location. If the player declines, the passenger is removed, and the system generates a new job.
Picking up Passenger - Once the job is accepted a timer to pick up the passenger is started to keep track how long it takes for the player to reach the passenger. - The player is directed to the passengers location through the use of a UI arrow which points in the passengers direction. - The passenger will be seen waiting with a golden aura and pointer which helps make them stand out against the map. - Once the player has found the passenger they will drive close to the pavement and stop, once stopped the passenger will walk towards the vehicle and choose the closest available door and open it. Dropping off Passenger - Once stopped on the spot the door the passenger is in will open they will get out and the job will be completed. - A HUD panel will appear showing the details of the drop off displaying the time it took the player to drop off and pick up the passenger. These aspects will also directly impact the rating of the job which impact the tip the player can receive.
The feature can easily be expanded to include more complex job scenarios or passenger traits without overhauling the core mechanics. Randomization in job generation ensures variety without redundancy, keeping the system computationally efficient.

The Red Light Fine system is a core mechanic that adds realism and challenge to the gameplay by enforcing traffic laws. When the player drives through a red traffic light, they incur a monetary penalty. This system encourages players to adhere to realistic driving behaviour, adding depth to the simulation and increasing the difficulty of managing their in-game finances.
The system uses collision boxes or trigger zones at intersections to detect if the player’s vehicle crosses the line while the traffic light is red. When a violation is detected, a penalty is applied to the player's current balance. An alert is displayed on the HUD, notifying the player of the fine, including the amount deducted.
The system aims to create a realistic traffic environment where players must abide by traffic laws. Fines act as a soft punishment, pushing players to consider the financial impact of reckless driving. The design allows for easy expansion, such as implementing additional traffic rules.

The job acceptance feature is a crucial part of the gameplay loop that allows players to decide whether to accept or decline a passenger’s request. Upon accepting a job a pointer system guides the player to the passenger's location. If the player declines, the passenger is removed, and the system generates a new job.
A collision event checks if the player's vehicle intersects with other valid objects it then takes the speed of the player to decide how bad of a impact the collision was.
The system incentivizes cautious driving, adding a layer of realism and responsibility to gameplay. By tying the fines to monetary consequences, players are encouraged to minimize reckless behaviour, balancing fun and strategy.

The Vehicle Management system is a core gameplay mechanic, enabling players to oversee and optimize their fleet of vehicles. This system provides options for purchasing new vehicles, inspecting the fleet, and managing repairs. It ensures that the player’s fleet remains functional and competitive, adding a strategic layer to the game.
Purchasing Vehicles: Players can access a "Garage Menu" to view available vehicles with varying stats. A vehicle purchase triggers a reduction in the player's balance and adds the selected vehicle to the garage. Inspecting Vehicles: The player can view each vehicle's current condition, including metrics like durability, mileage, and fuel levels. This information is displayed using a UI panel, dynamically updated based on gameplay events. Repair System: Vehicles degrade over time or take damage during collisions. Repairing involves deducting repair costs from the player’s balance while restoring the vehicle's stats.
The system incentivizes players to maintain their fleet, balancing gameplay resources like earnings from jobs and repair costs. Modular blueprint structures allow for easy additions to the fleet management system.

The upgrade system allows players to improve aspects of their gameplay by reducing operational costs and enhancing rewards. Players can unlock upgrades that decrease vehicle repair costs, reduce fines for violations, and increase the experience points (XP) earned from jobs, creating a sense of progression and efficiency in their operations.
Reduce Fines: Lowers the penalty amounts for infractions such as running red lights or collisions. Increase XP Gains: Multiplies the XP earned per job, allowing faster levelling and access to advanced content. Reduce Vehicle Repair Costs: Decreases the amount deducted from the player’s earnings when repairing vehicles.
Upgrades cater to different playstyles cost-conscious players might prioritize reducing repair or fine costs. Players focused on progression could prioritize increasing XP gains. Present the upgrades as meaningful choices that impact long-term gameplay.

The hiring and inspecting employees feature is a management aspect of the game where players can recruit and manage a team of employees to expand their taxi business. Each employee comes with unique stats this system allows players to strategically grow their fleet and optimize revenue by assigning employees to specific vehicles. Players can inspect employees to view detailed information about their attributes, providing insights into how they might perform and helping with decision-making for task assignments or improvements.
Employees are generated dynamically with random stats such as name, potential, and experience.
The system incentivizes players to maintain their fleet, balancing gameplay resources like earnings from jobs and repair costs. Modular blueprint structures allow for easy additions to the fleet management system. Hired employees are added to the player’s roster and linked to the fleet management system.

The employee assignment system allows players to manage their workforce by assigning hired employees to specific tasks, such as driving vehicles. This feature enables strategic gameplay, where players maximize profits and efficiency by choosing the right employee for the right job based on their stats.
A list of available vehicles is displayed, along with details such as their condition and upgrades. Once an employee is selected and assigned to a vehicle, their unique identifier (ID) is linked to the vehicle object, activating it as "in use." The system dynamically updates the employee's status to "Assigned." A check prevents assigning the same employee to multiple vehicles. The game logic tracks the employee's performance during jobs, updating their attributes or earning experience based on outcomes. A feature allows players to "recall" an employee from a job, returning them to the management pool and marking their vehicle as available.
Intuitive UI layout to simplify navigation. The design uses clear panels showing employees and vehicles side-by-side for seamless selection. The assignment system is modular, enabling future expansion to include additional roles or dynamic events affecting employee availability.

The HUD is a multifunctional interface that provides players with essential game information at a glance, enabling efficient gameplay without obstructing the driving experience. Key features are strategically placed to ensure visibility and accessibility during intense gameplay moments.
