Area3D

Area3D detects when things enter and exit it

Use it when

You want to create a space that warns you when objects enter or exit it

Examples

  • Attaching a hurt box to a character so it can take damage
  • Attracting coins to the player when in range
  • Opening a chest when standing next to it and pressing a button

Path3D

Path3D and PathFollow3D constrain the movement of child nodes

Use it when

You want to constrain movement or rotation of objects along a smooth curve in 3D space

Examples

  • Moving units along paths generated by A* pathfinding
  • Moving cards from the player hand to the game board along randomly generated paths
  • Designing moving platforms that follow complex paths
  • Creating vector force fields that affect rigid bodies
  • Making a character grind on rails in a 3D environment

RayCast3D

RayCast3D detects bodies along a line in 3D space

Use it when

You want to check for objects along a line in 3D space

Examples

  • Detecting if an AI turret has line of sight to the player
  • Checking for platforms and ledges a character can climb
  • Firing bullets or laser beams at targets
  • Creating enemy pathfinding systems

Camera3D

Camera3D allows you to see in 3D space

Use it when

You want to see and manipulate the view in 3D environments

Examples

  • Creating a first-person camera that follows player movement
  • Making a third-person camera that orbits around the player
  • Increasing field of view when the player sprints
  • Smoothly moving the camera between different targets
  • Adding screen shake effects to increase impact

CharacterBody3D

CharacterBody3D lets you code custom 3D movement

Use it when

You want to create a player or AI-controlled entity that interacts with the physics environment

Examples

  • Creating a 3D platform character that can walk, jump, and stomp enemies
  • Designing a first-person controller for an FPS game
  • Making characters stick to and climb walls with wall jumping
  • Walking on rotating and moving platforms
  • Pushing rigid bodies with your character
