配置，按该shader新增材质
Outline Width控制描边
Line Speed控制闪光速度
当然，还可以修改对应的颜色
代码控制物品描边显示隐藏
csharp
using UnityEngine;
//拾取脚本
public class PickUpController : MonoBehaviour
{
public float maxDistance = 3f; // 最大检测距离
public LayerMask layerMask; // 检测层级
public GameObject uiText; // 显示物品名称的 UI 文本组件
Transform lastHitInfo;
void Start()
{
uiText.SetActive(false); // 初始状态下 UI 文本组件不可见
}
void Update()
{
// 从相机屏幕中心向前发射一条射线
Ray ray = Camera.main.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0f));
RaycastHit hitInfo;
if (Physics.Raycast(ray, out hitInfo, maxDistance, layerMask))
{
lastHitInfo = hitInfo.transform;
uiText.SetActive(true);
//设置物品描边
SetOutline(lastHitInfo, 0.01f);
//hitInfo.transform.CompareTag("PickUpItem") 需要的话可以再加标签判断
if (Input.GetKeyDown(KeyCode.E))
{
PickUpItem(lastHitInfo);
}
}
else
{
uiText.SetActive(false);
if (lastHitInfo != null) SetOutline(lastHitInfo, 0f);
}
}
// 拾取物体逻辑
void PickUpItem(Transform item)
{
//。。。
}
//设置物品描边
void SetOutline(Transform obj, float width)
{
Renderer renderer = obj.GetComponent<Renderer>();
if (renderer != null)
{
Material material = renderer.material;
material.SetFloat("_ASEOutlineWidth", width);
}
foreach (Transform child in obj)
{
SetOutline(child, width);
}
}
}效果演示
