Fully integrated in the 2D URP scene, like a sprite

Effects are applied per pixel distance, not per actual distance

Starting at one endpoint of the line, color patterns progress one pixel at a time towards the other endpoint.

Thickness can behave in 2 different ways

It can be constant on the screen disregarding the orthogonal size of the camera.
Or it can adapt to it.

Reduced pixel vibration when moving the camera

The camera's imaginary grid where the line is drawn does not exactly match the screen's grid, and the position of each point in the line does not coincide with the center of each cell in that grid either. That produces imprecisions when either points change their position or the camera moves.
Adding some adjustments to the position of each point before drawing prevents that from happening and let us move lines smoothly, no matter their thickness.

Editor preview of the line

You can add, remove or move points of the line strip in the scene view, and see a preview of it, including its visual effects. It will not match the actual rendering of the line because it uses the editor's camera.

Visual Effects

Dotted lines

You can choose the length, in pixels, of the dots and the length of the space between them.
An offset can be applied to achieve interesting effects.
When dotted lines use textures, colors are applied to each dot, in order, no matter the dot length.

Textured lines

Define color sequences that will repeat along the entire line strip, starting at one endpoint.
Color sequences can be stored in textures.

Color gradients

Lines can be colored using a 2-colors gradient whose length and starting position can be defined as desired. Texture and gradient colors are mixed.
Enable the adaptive gradient length if you want the color gradient to extend along the line regardless of its length.

Bounds offset

A line strip is defined by a set of points, but you can choose at which pixel the line starts and how many pixels will be drawn from there.
Changing the start point may affect the offset of the other visual effects, optionally.

Overlay texture

A texture can be projected on the line. The position of the texture does not depend on the position of the line. This can be used to achieve the effect of a laser ray that goes through the smoke of a room, for example.
