1. In the project, sometimes it is necessary to display the product and let the model rotate automatically
The following code is the automatic rotation of the model
public class AutoRotationModel : MonoBehaviour
{
public float speed = 25;
void Update()
{
transform.Rotate(0, speed * Time.deltaTime, 0, Space.Self);
}
}
2. There is automatic rotation, there must be manual rotation to view the model
The following code will show the manual rotation of the model
public class RotateTest : MonoBehaviour
{
float h;
float v;
float Xspeed = 20.0f;
float Yspeed = 1.0f;
public float xMin;
public float xMax;
public float distance = 10.0f;
public Camera cam;
public bool isVectore = true;
public float camSpeed;
public bool isRotate = false;
public bool X;
public bool Y;
public bool Z;
void Start()
{
cam = GameObject.Find("Camera").GetComponent<Camera>();
}
void Update()
{
if (Input.GetMouseButton(0))
{
if (!isRotate)
{
return;
}
h = Input.GetAxis("Mouse X");
v = Input.GetAxis("Mouse Y");
if (Mathf.Abs(h) >= Mathf.Abs(v))
{
if (h < 0)
{
transform.Rotate(0, -Time.deltaTime * Xspeed * 100.0f * -h, 0);
}
if (h > 0)
{
transform.Rotate(0, Time.deltaTime * Xspeed * 100.0f * h, 0);
}
}
else
{
if (!isVectore)
{
return;
}
if (v < 0)
{
transform.Rotate(Time.deltaTime * Yspeed * 100.0f * v, 0, 0, Space.World);
}
if (v > 0)
{
transform.Rotate(-Time.deltaTime * Yspeed * 100.0f * -v, 0, 0, Space.World);
}
}
}
}
bool isEnlarge(Vector2 oP1, Vector2 oP2, Vector2 nP1, Vector2 nP2)
{
float leng1 = Mathf.Sqrt((oP1.x - oP2.x) * (oP1.x - oP2.x) + (oP1.y - oP2.y) * (oP1.y - oP2.y));
float leng2 = Mathf.Sqrt((nP1.x - nP2.x) * (nP1.x - nP2.x) + (nP1.y - nP2.y) * (nP1.y - nP2.y));
if (leng1 < leng2)
{
return true;
}
else
{
return false;
}
}
}
