Scrolling UVs

Scrolling UVs

Overview

A C# script that smoothly scrolls a material's UVs in an arbitrary direction/speed given by "Uv Animation Rate". Supports changing which material index and texture name, but the defaults will work with single material, single texture renderers.

C#

using UnityEngine;
using System.Collections;
 
public class ScrollingUVs : MonoBehaviour 
{
    public int materialIndex = 0;
    public Vector2 uvAnimationRate = new Vector2( 1.0f, 0.0f );
    public string textureName = "_MainTex";
 
    Vector2 uvOffset = Vector2.zero;
 
    void LateUpdate() 
    {
        uvOffset += ( uvAnimationRate * Time.deltaTime );
        if( renderer.enabled )
        {
            renderer.materials[ materialIndex ].SetTextureOffset( textureName, uvOffset );
        }
    }
}
