This repository holds a sample project showing how to create a dynamic rainbow trail that follows the player character. This visual is inspired by the classic game Bit.Trip Runner.

This demo utilizes a technique with Line2D nodes to draw points at the top_level so that each point exists in the top-level space. This allows points to trail off from their parent element.
This GDScript is the most important part of this project.
extends Node2D
var lines: Array[Line2D]
@export var max_points := 100
func _ready() -> void:
for node in get_children():
if node is Line2D:
# allow each line to set position based in scene
node.top_level = true
# ignore the initial points because
# things are about to get really weird :)
node.clear_points()
lines.append(node)
func _physics_process(delta: float) -> void:
var point = global_position
for line in lines:
line.add_point(point)
if line.points.size() > max_points:
line.remove_point(0)This technique can be used in many 2D games for tire tracks, space laser trails, or wavy scarves.
Enjoy!
