Peer-Review for Programming Exercise 2

Peer-reviewer Information

Solution Assessment

Stage 1: Initialization and Setup

  • Great
  • Perfect
  • Good
  • Satisfactory
  • Unsatisfactory

Justification

The initialization and setup logic is generally well-handled. The target, dist_above_target, and other variables are well-defined and logically grouped. dist_above_target is used to set an initial camera height relative to the target.

To improve this, I recommend adding a check to confirm target is assigned before accessing target.position in _process. If target is null, this could lead to runtime errors.

Stage 2: Camera Controls

  • Perfect
  • Great
  • Good
  • Satisfactory
  • Unsatisfactory

Justification

The camera zoom controls are implemented well, with the zoom_in and zoom_out functions properly clamping dist_above_target between min_zoom and max_zoom values. The toggle for draw_camera_logic is also clear and functional.

However, consider enhancing user experience by adding smooth zoom transitions, which could be done using interpolation (e.g., lerp). This would make zoom adjustments feel more gradual and less abrupt.

Stage 3: Optional Camera Tilt

  • Perfect
  • Great
  • Good
  • Satisfactory
  • Unsatisfactory

Justification

The commented-out tilt functionality is a solid foundation, and the logic for gradual re-centering of _camera_tilt_rad is an excellent touch. However, the code could benefit from implementing a maximum tilt angle to prevent the camera from rotating too far left or right. You could achieve this by clamping _camera_tilt_rad within a defined range.

Stage 4: Camera Following Logic

  • Perfect
  • Great
  • Good
  • Satisfactory
  • Unsatisfactory

Justification

The camera's position is set to follow the target based on its Y position, which is effective for a basic follow system. One enhancement could be to add a smooth follow effect (e.g., using lerp), which would create a lag effect for a more natural camera movement.

Stage 5: Placeholder Draw Logic

  • Perfect
  • Great
  • Good
  • Satisfactory
  • Unsatisfactory

Justification

The draw_logic function is currently a placeholder. It's clear this could be expanded with debugging or visualization logic if necessary. This could add value by visualizing the camera's position and target alignment, particularly for debugging purposes.

Code Style

Description

The code generally follows GDScript conventions, with clear variable names and logical grouping of functions. However, a few minor style improvements could be made.

Style Guide Infractions

  • Unnecessary comments - There are several commented-out lines related to camera_tilt which can be removed or replaced with active functionality. Consider keeping comments that explain complex logic, rather than entire blocks of unused code.

Style Guide Exemplars

  • Consistent variable naming - Variables such as dist_above_target and zoom_speed are self-explanatory and follow GDScript's naming conventions.

Best Practices

Description

The code is close to following best practices, though a few modifications could enhance maintainability and readability.

Best Practices Infractions

  • Null check for target: Before accessing target.position, add a check to ensure target is not null. This will prevent potential runtime errors.
  • Smooth transitions: Implementing lerp for smoother camera transitions would be a useful enhancement, especially for zoom and follow functions.

Best Practices Exemplars

  • Effective use of clamping: The clampf function for zooming in and out is a good use of clamping to maintain values within the defined range.
