Problem in LERP Rotaion Based on InputField Value

Question

Hi All,

I am trying to do Lerp rotation animation in x axis by getting values from InputField. During runtime, Everytime I type a value in InputField and press Enter, I call a function to update the latest Value to the class. The GameObject should rotate and stop as per the value. Here's how I coded. Not works as expected. Could you Help me:

public class getInputFocus : MonoBehaviour {

 public GameObject rotPlate;
 private float inputValue;
 private Vector3 rotateTo;
 private float rotSpeed = 2.0f;

 void Update () {
 
     if (rotPlate.transform.eulerAngles.x != rotateTo.x) {
             rotPlate.transform.eulerAngles = Vector3.Lerp (rotPlate.transform.eulerAngles, rotateTo, Time.deltaTime*rotSpeed);
     } 
 }

 public void getInput(string UserInput) // From InputField
 {
     Debug.Log (UserInput);

     inputValue = float.Parse (UserInput);
     //User values should be within 0 to 100
     if((inputValue <= 100) && (inputValue >= 0))
     {
         //Convert values into Angle Because roation angle should be 0-90
         float newValue = (inputValue / 100) * 90; 
         rotateTo.x = newValue;
     }
 }

}

I think this is the problem of gimbal lock. Maybe you can try Quaternion.Lerp as follows:

 void Update ()
 {
     Quaternion targetRotation = Quaternion.Euler(rotateTo); 
 
     if (!Mathf.Approximately(Quaternion.Angle(rotPlate.transform.rotation, targetRotation), 0))
     {
         rotPlate.transform.rotation = 
             Quaternion.Lerp(rotPlate.transform.rotation, targetRotation, Time.deltaTime * rotSpeed);
     }
 }
