C# Object instantly rotates instead of rotating slowly

What gives? I added a float speed and the Time.deltaTime

The idea is for it to rotate 90 degrees every click on the X axis. I want it to happen fast but not instantly.

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class RotObject : MonoBehaviour {
6.     public float speed = 1f;
7.     void OnMouseDown () {
8.         transform.Rotate((90f),(0),(0) * (speed * Time.deltaTime));
9.     }
10.  
11. }
12.  
13.  

 

I can't check as I have no PC at the moment but try putting the vector stuff in brackets rather than each vector #

1. transform.Rotate((90f,0,0) * (speed * Time.deltaTime));

 

Hi,

I'm not sure i understand your purpose but i will try to respond...

1) In your exemple the object will turn instantly for 90°. This is why you saw no rotation.
2) Why this " (0)*(speed*Time.deltaTime) " ? you know 0 * X will always give you a 0 as result, this operation is useless.


if you want to rotate your object slowly use the Update loop, like this

Code (CSharp):

1.  
2. public float speed = 0.1f;
3.  
4. void Update()
5. {
6. transform.Rotate((5f),(0),(0));
7. }

or if you want to rotate your object when the player click, use this code

Code (CSharp):

1.   public float speed = 1f;
2.     void OnMouseDown () {
3.         transform.Rotate((30f),(0),(0));
4.     }

Sorry for my bad english

 

Thank you Karl, but I get "the reference script for this behavior is missing".

Why do you think I don't see the rotation? I do. My object rotates fine, just instantly.

Why this " (0)*(speed*Time.deltaTime) " ? you know 0 * X will always give you a 0 as result, this operation is useless.

That's why I have the "90" there

transform.Rotate((90f),(0),(0)*(speed*Time.deltaTime));

. If I could isolate the "90" it would be great.

I don't want it to rotate instantly, I want it to rotate slowly till it reaches its "destination angle".

 

I think Kemars point is, its happening instantly, you are not seeing a transition from start to finish as you want, and this is because you are just setting the rotation to 90f and multiplying the last value (which will have no impact)

 

That's exactly my question...how is it possible to make it slowly rotate?


Karl.Jones...THANK YOU VERY MUCH! I just had the name of the class wrong. Your script works I'll need to learn how you did it now ^^

 

Yea I just figured it makes more sense to do it without animation, so that's why I just prefered to use the inherit unity transform functions.

Although it seems the second click I do rotates the cube back and it strangely becomes -5.008956e-06 degrees. I can't really understand from your code where it's coming from, but I did add a modulus so it will rotate if it's divisible by 90 degrees (otherwise I can mess the rotation up by clicking on it before it finishes the 90 degrees rotation). I also changed the "var" from "Vector3"... "var" seems a pretty weird choice when you're coding in C#.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Rot : MonoBehaviour
5. {
6.     public float speed = 1f;
7.     public Vector3 rotAmount = new Vector3(90,0,0);
8.    
9.     IEnumerator OnMouseDown () // A couroutine can be run each frame so we can do animation.
10.     {
11.         if (transform.rotation.eulerAngles[0] % 90 == 0) {
12.             float endTime = Time.time + speed; // When to end the coroutine
13.             float step = 1f / speed; // How much to step by per sec
14.             Vector3 fromAngle = transform.eulerAngles; // start rotation
15.             Vector3 targetRot = transform.eulerAngles + rotAmount; // where we want to be at the end
16.             float t = 0; // how far we are. 0-1
17.             while (Time.time <= endTime) {
18.                 t += step * Time.deltaTime;
19.                 transform.eulerAngles = Vector3.Lerp (fromAngle, targetRot, t);
20.                 yield return 0;
21.             }
22.         }
23.     }
24. }
