Unity 绘制线条

1、Debug.DrawLine

public class Test : MonoBehaviour
{
    Vector3 end = new Vector3(10, 10, 10);

    // Update is called once per frame
    void Update()
    {
        Debug.DrawLine(Vector3.zero, end, Color.red);
    }
}

2、Debug.DrawRay

void Update()
{
    Debug.DrawRay(Vector3 start, Vector3 dir, Color color);
}

3、Gizmos.DrawLine：不用运行就可以直接在Scene窗口看见，白色的

private void OnDrawGizmos()
{
    Gizmos.DrawLine(camera.position, point);
}
