Are you building a 2D side-scroller, endless runner or a platformer? This is how you make your worlds even more immersive. Let's design and implement seamless endlessly scrolling backgrounds that move at different speeds, creating an illusion of depth in a 2D space. This is how to make parallax background Unity 2d.

Endlessly Scrolling Parallax backgrounds in 5 simple steps:

1) Create a new 2D project in Unity 6 (universal 2D render pipeline)
2) Import background images that will represent different layers (e.g., foreground, midground, and background).

3) Create and organize layers: Place each image into separate GameObjects, ensuring they are positioned at different depths on the Z-axis using "Sorting Layers" and "Order in Layer" fields.
4) Write the parallax script: Implement a C# script to adjust the movement speed of each background layer. Faster movement for foreground, slower for background.
5) Test and refine: Attach the script to your layers, play the scene, and tweak the speed values until the desired parallax effect is achieved.
