Lecture Notes: Camera Manipulation in Roblox

Introduction

• The lecture discusses camera manipulation in Roblox, focusing on:
  • Camera properties
  • Scripting to manipulate the camera

Spectate Mode Example

• The game allows spectate mode, moving the camera to a specific position.
• Example: Holding left shift to "Sprint" zooms the camera out, releasing it zooms back in.

Camera Manipulation in Roblox Studio

• Camera changes should happen on the local side for each player.
• Properties to Change
  • Starter Player Camera Properties
    • Zoom distance:
      • Max Zoom Distance: Default 128 (e.g., change to 20)
      • Min Zoom Distance: (e.g., change to 10)
    • Camera Mode Options:
      • Classic or Lock First Person
    • Camera Occlusion Mode:
      • Default vs. Invisicam (makes objects semi-transparent if obstructing view)

Camera Object in Workspace

• Located inside workspace with key properties:
  • Camera Subject: Reference part, default is player’s humanoid
  • Camera Type: Determines camera behavior (e.g., custom, attach, fixed, orbital)

Scripting Camera with Local Script

• Current Camera vs. Camera:
  • Use CurrentCamera to manipulate player's view.
• Script Example: Moving Camera CFrame
  • Set CameraType to scriptable to prevent Roblox from overriding script changes.
  • Use Tween Service for smooth transitions between start and end points.

Rendering Properties

• Field of View (FOV): Determines extent of visible world on screen.
  • Increase FOV to see more, decrease to zoom in.
• Focus: Point in the world for rendering priority.

Raycast Methods

• Get Parts Obscuring Target: Detects instances blocking a position from the camera.
  • Use ignoreList to specify parts to ignore in detection.

World to Screen Point Method

• Converts a 3D position to a 2D screen position relative to the camera.
• Practical Example: Displaying a coin image on the screen when collected.

Spectate Mode GUI System Challenge

• Create a GUI to change camera perspective between players.
• Use buttons to cycle through players and view their perspective.

Conclusion

• Encourage practice with camera manipulation and scripting.
• Mention Patreon for access to scripts and early video access.
