The editor camera provides free-flight navigation through the 3D viewport. It uses an acceleration-based movement model with mouse-driven rotation.

​
Controls

​
Movement Model

The camera uses a physics-inspired movement system:

​
Acceleration

When an arrow key is held, acceleration is applied in the corresponding direction. The acceleration magnitude is controlled by _accelerationMod.

​
Velocity

Velocity accumulates each frame based on acceleration. It is clamped to _maximumMovementSpeed to prevent extreme movement.

​
Deceleration

When no acceleration is applied (key released), velocity decays toward zero using _decelerationMod. This creates smooth stopping behavior.

​
Rotation

Mouse movement rotates the camera:
  • Horizontal mouse movement rotates around the world Y axis (yaw)
  • Vertical mouse movement adjusts the local pitch
  • Pitch is clamped to _maxXAngle (default: 80°) to prevent flipping
The rotation is stored as a Vector2 (pitch, yaw) and applied as local Euler angles.

​
Input States

​
Camera Enabled

When InputEnabled = true:
  • Mouse cursor is hidden and locked
  • Arrow keys move the camera
  • Mouse rotates the camera

​
Camera Disabled

When InputEnabled = false:
  • Mouse cursor is visible and unlocked
  • Arrow keys have no effect
  • Mouse movement has no effect
  • Used when menus are open

​
Position and Rotation Persistence

The camera’s position and rotation are saved between sessions:
  • Stored in EditorPersistentState.CameraPosition
  • Stored in EditorPersistentState.CameraRotation
  • Restored when the editor loads

​
Technical Details

  • The camera is an EditorController component attached to the main camera
  • Movement uses transform.Translate() in local space
  • Rotation uses transform.localEulerAngles
  • The camera maintains a Vector3 _moveSpeed for velocity tracking
  • Deceleration uses Mathf.MoveTowards for smooth decay
