How to make an object roate 180 on Z axis on each mouse click
I'm working on a project for school and I need an object to rotate 180 degrees when selected with the mouse. The first attempt only got the object to rotate a little each time however with some assistance I came up with the code below. The issue however is that while it rotates the first time 180, every other time it rotates 360. How do I correct my script so that it is operating properly (rotating 180 each time it is selected - basically flipping to upside down) Below is the code I currently have that is giving me the issue.
Many thanks,
Chris
using UnityEngine; using System.Collections;
public class Select3 : MonoBehaviour { float speed = 0;
void Start ()
{
}
void Update ()
{
transform.Rotate(0, 0, Time.deltaTime*speed);
Debug.Log (gameObject.transform.rotation.z);
Debug.Log (gameObject.transform.rotation.z *180);
if (Mathf.Abs(gameObject.transform.rotation.z)*180 >= 179.995)
{
speed = 0;
}
}
void OnMouseDown()
{
speed = 100;
}
}
transform.rotation.z return a "Rotator" not a float, please use transform.rotation.eulerAngles.z
void Start () {
}
void Update () {
alpha += speed ;
alpha = Mathf.Clamp(alpha, 0, 1) ;
transform.rotation.eulerAngles.z = Mathf.Lerp(0, 180, alpha) ;
}
void OnMouseDown(){
speed*=-1 ;
}
"speed" variable must < 1 or you will see the instantly change, suggest 0.05
I'm sorry I tried it and I get a lot of errors. I tried as new code and also put it in to my existing code. The big errors that I get are that
"The name 'alpha does not exist in the current context"
Cannot modify a value type return value of "UnityEngine.Quaternion.eulerAngles". Consider storing the value in a temporary variable
Cannot modify a value type return value of "UnityEngine.Transform.rotation'. Consider storing the value in a temporary variable
Those are the errors I get if it's a new script and if it's compiled with the original. I appreciate the help in suggesting a code, just not sure why I get the errors.
$$anonymous$$any Thanks

You need to define the variables alpha and speed as well as another variable of type Vector3 which you should save transform.rotation.eulerAngles to, then modify, then set transform.rotation.eulerAngles to. Perhaps do a few tutorials first if you don't understand variables :)
thank you Scribe. I have been doing tutorials. I'm just not picking it up that easily. However I just didn't understand what alpha meant. I'll go back over the tutorials.
Sorry about unclear code. And Thank for Scribe's comment.
alpha means the value's position "property" between two float.
If alpha = 0, the value will return the first value in $$anonymous$$athf.Lerp(first,second,alpha) . If alpha=1, return second value.
So if alpha =0.5, it may be 90, the average.
