Goal
I want to achieve something similar to this animation:
What I have
My project tree looks like this:
Control > Panel > Path2D > PathFollow2D > Node2D > Sprite & (Node > Line2D)
The Panel
is the green background. The Path2D
together with the PathFollow2D
move the Sprite
along the desired route.
My idea is to draw the pattern using multiple Line2D
nodes. First I tried to just use one single long line for the full path but after adding ~5100 Vector2
objects to the Line2D.Points
property, the line stopped working. Some of the first few points (except the very first one) disappear and adding new points to the Line2D.Points
property has no effect at all.
I also ran into the error ERROR: _draw_polygon: Condition ' buffer_ofs > data.polygon_buffer_size ' is true.
a couple of times.
Question
What other options are there to achieve something similar to this?
I think you can use sprites of those 2 stripes and use shaders to make them visible when that machine moves over them.

Hi @supper_raptor, thanks for your answer. Unfortunately I have no clue about shaders… Can you recommend any resources to get started?
