在Unity中,获取Mesh对象上第一个顶点(Vertex)和最后一个顶点的代码通常涉及使用`Mesh`组件提供的数据访问功能。这里是一个简单的示例:
```csharp
using UnityEngine;
using System.Collections.Generic;
public class MeshPointGetter : MonoBehaviour
{
public Mesh mesh; // 将要操作的网格
void Start()
{
List<Vector3> vertices = mesh.vertices; // 获取所有顶点
if (vertices.Count > 0)
{
Vector3 firstPoint = vertices[0]; // 第一个顶点
Vector3 lastPoint = vertices[vertices.Count - 1]; // 最后一个顶点
Debug.Log("First point: " + firstPoint);
Debug.Log("Last point: " + lastPoint);
}
else
{
Debug.LogError("Mesh is empty or no vertices found.");
}
}
}
```
在这个脚本中,首先从`Mesh`组件中获取所有顶点(`vertices`),然后分别取第一个(索引为0)和最后一个(索引为`vertices.Count - 1`)。记得给`mesh`组件绑定到游戏物体上。
