unity背景滚动

背景滚动其实就是滚动模型的纹理Offset而已，修改Renderer组件下的Material的贴图的偏移即可。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;


public class Texturescorll : MonoBehaviour {
    public float speed = .5f;
    Renderer renderer;
    float offset;
    void Start()
    {
        renderer = GetComponent<Renderer>();
    }
    void Update()
    {
        // Increase offset based on time
        offset += Time.deltaTime * speed;
        // Keep offset between 0 and 1
        if (offset > 1)
            offset -= 1;
        // Apply the offset to the material
        renderer.material.mainTextureOffset = new Vector2(0, offset);
    }
}

放在3d视角里就是3d视角的滚动
