Class LabyrinthGraphics2D

java.lang.Object

net.regsirius06.engine.core.graphics.labyrinth.default2D.LabyrinthGraphics2D

All Implemented Interfaces:

Drawable2D

public class LabyrinthGraphics2D
extends Object
implements Drawable2D

The LabyrinthGraphics2D class provides the logic for rendering a 2D labyrinth with ray casting effects, simulating what the player sees, including light sources, reflections, and walls.

This class visualizes the labyrinth and displays the player's perspective on the surrounding environment, taking into account factors such as lighting, intersections with objects, and reflections.

It implements the Drawable2D interface, which allows the labyrinth to be drawn on a 2D canvas.

Constructor Details

LabyrinthGraphics2D

public LabyrinthGraphics2D(int width,
 int height,
 Labyrinth2D labyrinth,
 Player player)

Constructor that initializes the LabyrinthGraphics2D instance.

Parameters:

width - The width of the canvas for rendering.

height - The height of the canvas for rendering.

labyrinth - The labyrinth instance representing the environment.

player - The player instance determining the position and direction.

Method Details

getVisibleLightSources

public final Set<Wall> getVisibleLightSources()

Returns the set of visible light sources.

Returns:

A set of light sources that are visible to the player.

draw

public final void draw(Graphics2D g2d)

Draws the 2D visualization of the labyrinth and what the player sees.

Specified by:

draw in interface Drawable2D

Parameters:

g2d - The Graphics2D object used for drawing the scene.

visualize

protected void visualize(Graphics2D g2d)

Visualizes the labyrinth, including walls and light sources.

Parameters:

g2d - The Graphics2D object used for rendering the scene.

claimAngle

protected static double claimAngle(double angle)
