AnimeSpeedLines
by 2Retr0
AnimeSpeedLines adds a screen effect of speed lines drawn over the view, with the lines' opacity tuned to how bright the current image is.
What it does
Opacity follows the brightness of the image on screen, so the lines stay visible at night and fade in daylight, keeping them from covering the scene the same way in every environment. Velocity correction compares the direction the player is moving with the direction the camera faces, so the lines still read correctly when moving sideways, for example while looking to the side from a moving boat.
The effect is an exaggerated demonstration; in actual gameplay it is slightly less obtrusive. The author used the Complementary Shaders pack for the demo footage. The mod was first made as a way to learn and practice GLSL, and the author shares it for others to try.
The mod is a client-side only Fabric addition that needs Fabric API. It is released under the MIT License and is open source, with the source code and an issue tracker public. Satin API is bundled inside the file, so no separate install is needed for it. Files target 1.20.2 – 1.20.4.
Key features
Brightness-based opacity
Line opacity is adjusted according to the brightness of the current image, reducing obtrusiveness.
Velocity-corrected direction
The lines account for the difference between the player's movement direction and the camera direction.
Uniform contrast
The effect keeps a more even contrast across different environments such as day and night scenes.
Bundled Satin API
Satin API is included inside the mod file, so the mod does not ask players to install it separately.

Vehicle travel
Moving sideways while in a vehicle, such as a boat, is one case the velocity correction handles.
Who it’s for: Players who want a visual speed effect on their own client, and people who want to study or adapt a GLSL post-processing effect built on Fabric.

What the author says
*Effect is exaggerated in the demo—it's slightly less obtrusive in-game! Shaders used in demo are Complementary Shaders. Originally, I made this mod just to learn/practice glsl, but I figured some may find it fun to use. If you have any suggestions, please let me know!
