Unity添加组件(三角形)不工作

下面的代码应该为三角形添加一个3d对象,但我收到错误
Assets/Scripts/MakeTriangle.cs(6,28):错误CS0120:需要一个对象引用来访问非静态成员' UnityEngine.GameObject.AddComponent(System.Type)'
using UnityEngine;
using System.Collections;
public class MakeTriangle : MonoBehaviour {
void Start(){
GameObject.AddComponent<MeshFilter>();
GameObject.AddComponent<MeshRenderer>();
Mesh mesh = GetComponent<MeshFilter> ().mesh;
mesh.Clear();
mesh.vertices = new Vector3[] {new Vector3(0,0,0), new Vector3(0,1,0), new Vector3(1,1,0)};
mesh.uv = new Vector2[] {new Vector2(0,0), new Vector2(0,1), new Vector2(1,1)};
mesh.triangles = new int[] {0,1,2};
}
}
将GameObject小写为GameObject。GameObject是一种类型,GameObject是对附加GameObject的引用。
你还添加了两次网格过滤器,这是一个错误。缓存您的组件,以便以后可以像这样使用它们:
编辑:认为你的"GetComponent"是另一个"AddComponent"。所以我收回我上次的声明,说那是个错误。
using UnityEngine;
using System.Collections;
public class MakeTriangle : MonoBehaviour {
MeshFilter filter;
MeshRenderer renderer;
Mesh mesh;
void Start(){
filter = gameObject.AddComponent<MeshFilter>();
renderer = gameObject.AddComponent<MeshRenderer>();
mesh = filter.mesh;
mesh.Clear();
mesh.vertices = new Vector3[] {new Vector3(0,0,0), new Vector3(0,1,0), new Vector3(1,1,0)};
mesh.uv = new Vector2[] {new Vector2(0,0), new Vector2(0,1), new Vector2(1,1)};
mesh.triangles = new int[] {0,1,2};
}
}
你应该将MeshFilter添加到gameObject而不是gameObject类中,而且你没有在任何地方使用MeshRenderer,所以为什么要添加它
MeshFilter filter;
MeshRenderer renderer;
Mesh mesh;
void Start(){
gameObject.AddComponent<MeshFilter>();
Mesh mesh = gameObject.GetComponent<MeshFilter> ().mesh;
mesh.Clear();
mesh.vertices = new Vector3[] {new Vector3(0,0,0), new Vector3(0,1,0), new Vector3(1,1,0)};
mesh.uv = new Vector2[] {new Vector2(0,0), new Vector2(0,1), new Vector2(1,1)};
mesh.triangles = new int[] {0,1,2};
}
