Why is rotating an 360 degrees over 1 second so difficult

The code is not rotating right 360
It rotates in a chunky fashion each time the BarrelRight(); is called. The rotation amount is far less than 360 as well. I don't get it.
I just want 1 smooth rotation over 1 second and I do not understand why it doesn't function.

Code (CSharp):

1. void Update(){
2.           if (Input.GetKeyDown(KeyCode.RightArrow)) {
3.  
4.             if (buttonPressTimer > 0) {
5.                 BarrelRight();
6.             }
7.             else {
8.                 buttonPressTimer += 0.5;
9.                 print(buttonPressTimer);
10.             }
11.            
12.         }
13. }
14.     void BarrelRight() {
15.         transform.Rotate(Vector3.up, 360f * Time.deltaTime / 1f);
16.     }

 

take a look at this post

It probably has to do with your timer code, which we don't see. Try not using the timer code at all and it should rotate smoothly.

 

My player is kinetic not physics controlled.

The button timer is just to detect if the button was double tapped or not.

 

This code in update will rotate smoothly:

Code (csharp):

1.  
2.  transform.Rotate(Vector3.up, 360f * Time.deltaTime / 1f);
3.  

Try it.

 

You are using GetKeyDown which only fires once per held keypress. use GetKey if you want to rotate each frame while holding the key. Also I don't get what you are doing with buttonPressTimer.
