Vision2D

A Godot plugin (version 4.x) for rendering 2D fields of vision, inspired by Teleglitch.

The plugin renders a number of polygons covering up parts of the screen that are outside the observer's field of vision.

The field of vision can be blocked with a VisionOccluderLine node or a VisionOccluderPolygon node:

• VisionOccluderLine - Represents a line that blocks the field of vision. Extends Line2D.
• VisionOccluderPolygon - Represents a polygon that blocks the field of vision. Extends Polygon2D.

Both nodes have the following properties:

• observer: Node2D - A Node2D representing the position of the observer.
• shadow_color: Color - Color of the shadow that covers up the screen.
• size: float - Size of the shade that covers up the screen.
• penetration: float - Determines how deep the vision can penetrate this occluder.
• max_segment_size: float - Max. size of the segment that casts the shadow (smaller segments -> more detail).
