Scrolling Background in Unity

Scrolling Background in 2D

1. Select the original Texture (not the GameObject).
2. Change Texture Type to Sprite (2D and UI).
3. Change Wrap Mode to Repeat.
4. Click Apply.
5. Create a Quad object: GameObject -> 3D Object ->Quad.
6. Scale the Quad to the size you want.
7. Create a light: GameObject->Light->Directional Light.
8. Adjust the light intensity to whatever you like.
9. Drag your Texture/Sprite to the Quad in the Scene View.

Now, create your script:

public class OffsetScrolling : MonoBehaviour {
    public float scrollSpeed;

    private Renderer renderer;
    private Vector2 savedOffset;

    void Start () {
        renderer = GetComponent<Renderer> ();
    }

    void Update () {
	float x = Mathf.Repeat (Time.time * scrollSpeed, 1);
	Vector2 offset = new Vector2 (x, 0);
	renderer.sharedMaterial.SetTextureOffset("_MainTex", offset);
    }
}

Note: For 2D, you can also use a Plane and the code above should work fine.

Thank you very much for sharing!

@offbeatside I'm glad it was helpful for you 😄

Thank you, just used it in a project, very useful 👍

@teo-sk 🙌

it diden worked pls help

thank u

Thank you! Works great with a Quad and Plane in 2D scenes.

Nice, thank you! Exactly what I needed. Quick note: you can change the direction of the moving texture by giving it a negative scrollSpeed.

On URP, the Lit shader main texture map is called "_BaseMap" btw.
