  • Build a paper prototype before client meeting on Wednesday Feb 14
  • Try to combine the tool feature and vehicle movement before end of the week
  • Build a playable prototype in Unreal

After last week’s meeting, we decide to build a paper prototype for client to experience our game. Our prototype will mainly focus on let players can experience 1 task and explore inside the heart. Programming wise we need to combine the vehicle’s air mode’s feature and spray feature and build a playable prototype.

The feedback from the client after the playtest praised our game experience, finding it very engaging and in line with the “Driving wit care” theme.

After playtesting, the client suggested that we need to pay attention to the scope like limiting the features of vehicles to 1-2 types, also addressing scaling issues and keep researching on the “obstacles and terrain” in the heart.


  • We simulated the internal environment of the heart using 4 boxes: the ventricles and atria.
  • The sticky notes on the boxes were used to simulate viruses on the walls of the heart.
  • The columns suspended in the air represent “obstacles” within the heart, and we placed rubber bands to simulate a feedback system: if the player collides or acts too aggressively, the rubber bands will fall off, indicating damage to the human body.
Client learning how to control the vehicle

The small white box is the robotic vehicle that the player needs to control. It is suspended in the air by two thin strings for maneuvering.

  • Speed and collision detection
    • When the vehicle hit the heart slowly, it will be fine but if drive too fast, it will hurt the heart.
  • Spray Features implement
  • Bacteria effects implement

Spray function

The UI of the steering wheel and pedals are complete. This UI will help players to understand how to control the vehicle.

The poster of the team was also completed.
