Untitled Godot Project

Background:
  • Project is currently under development
  • These are my current prototypes
  • First time in Godot
  • Tasked with creating NPCS and Dialogue System
NPC Behaviors
NPC States

  • Follow Path

  • Follow

  • Random Position

  • Idle

Follow Path
  • Gets points from a Curve3D node and moves to those points
  • Has 3 different methods to traverse
    • Once - traverse path then stop​
    • Loop - continuously traverse path
    • Reverse - loops path forward and back
  • Can also modify:​
    • Movement - speed of NPC​
    • Distance - The min distance to reach point

Follow Path State Variables

Follow
  • Moves toward the selected target
  • Can modify NPC movement speed

Follow State Variables

Random Position
  • Gets a random point within a circle and moves toward that position
  • ​Can modify:
    • Movement - speed of NPC​
    • Time out - max time until new position is given​
    • Radius - radius of the sphere​

Random Position Variables

Changing States
  • Need script to tell State Machine to go to another state
    • gets rid of states being tied together​
  • For now I use an enum to go to a specific state​​​

Example Test Code

NPC Head Rotation
  • Need NPC to rotate head towards the player when they are close to them
  • Used dot product and distance checks to make fov
  • Can modify:
    • ​Head Rotation - activate head rotation​
    • ​Target - the target to look at
    • ​Rotate Speed - speed of head rotation
    • ​Vertical Angle - min vertical angle to clamp to
    • View Width - min horizontal angle to clamp to
    • View Dist - max distance from target to start looking at
    • Debug - show debug lines

NPC Dialogue
  • Can interact with NPC and pop-up a Dialogue Box
  • Each Dialogue can have its own audio

Dialogue Example

Unmute to hear audio
