How to create endless background in a 2d top down game?

Question

I have a seamless background sprite, and I do not want the player to be able to reach the edge of the background.

Setting huge width and height in tiled drawmode doesn't sounds like a solution. How can I make something like this?

I want the background to appear outside the camera in the direction the player is moving.

I think instead of instantiating and destroying background panels every time I should once create them and then change their position.

It sounds like you have two valid solutions: making a huge sprite with tiling draw mode, or spawning panels of the image at a time and repositioning them as needed. Where do those solutions fall short of what you need? — DMGregory, Commented Oct 27, 2021 at 16:23
@DMGregory I don't know how to create a script that will reposition panels, that's what I'm asking. Does creating a huge sprite affects performance? If not then I'll just make a huge sprite. — tevse, Commented Oct 27, 2021 at 16:33
"Does X affect performance" is something you can answer more conclusively by measuring it. That way you don't have to worry about Internet hearsay giving you the wrong info — you can access the truth of the matter directly. — DMGregory, Commented Oct 27, 2021 at 16:35
You could also attach your background sprite to your camera, and use a shader to tile the texture in worldspace, so it automatically maintains a fixed relationship to the world even as the sprite/camera moves. — DMGregory, Commented Oct 27, 2021 at 16:38
Looks like you forgot to set the wrap mode on your texture in the import settings to "repeat". — DMGregory, Commented Oct 27, 2021 at 18:37

Attached background sprite to camera and then used that shader

Remember to set the sprite wrap mode to "repeat"
