Bevy resource providing facilities to draw lines.

Usage

use bevy::prelude::*;
use bevy_prototype_debug_lines::*;

// Draws 3 horizontal lines, which disappear after 1 frame.
fn some_system(mut lines: ResMut<DebugLines>) {
    lines.line(Vec3::new(-1.0, 1.0, 0.0), Vec3::new(1.0, 1.0, 0.0), 0.0);
    lines.line_colored(
        Vec3::new(-1.0, 0.0, 0.0),
        Vec3::new(1.0, 0.0, 0.0),
        0.0,
        Color::WHITE
    );
    lines.line_gradient(
        Vec3::new(-1.0, -1.0, 0.0),
        Vec3::new(1.0, -1.0, 0.0),
        0.0,
        Color::WHITE, Color::PINK
    );

Implementations

impl DebugLines

pub fn line(&mut self, start: Vec3, end: Vec3, duration: f32)

Draw a line in world space, or update an existing line

Arguments

• start - The start of the line in world space
• end - The end of the line in world space
• duration - Duration (in seconds) that the line should show for – a value of zero will show the line for 1 frame.

pub fn line_colored( &mut self, start: Vec3, end: Vec3, duration: f32, color: Color )

Draw a line in world space with a specified color, or update an existing line

Arguments

• start - The start of the line in world space
• end - The end of the line in world space
• duration - Duration (in seconds) that the line should show for – a value of zero will show the line for 1 frame.
• color - Line color

pub fn line_gradient( &mut self, start: Vec3, end: Vec3, duration: f32, start_color: Color, end_color: Color )

Draw a line in world space with a specified gradient color, or update an existing line

Arguments

• start - The start of the line in world space
• end - The end of the line in world space
• duration - Duration (in seconds) that the line should show for – a value of zero will show the line for 1 frame.
• start_color - Line color
• end_color - Line color
