Rotate in place

Unity Engine
1

Hello. I am attempting to use a script tin order to make the blade on my Helicopter spin 360* with a modifiable speed var.

I have done quite a bit of searching but i can only get info on spinning and rotating AROUND the origin point such as this for example:

using System;
using UnityEngine;
 
[AddComponentMenu("Scripts/Quests/SpinningSymbol")]
public class SpinningSymbol : MonoBehaviour
{
    private void Update()
    {
        transform.Rotate(Vector3.forward * Time.deltaTime * 100);
    }
}

If possible, can i get some assistance with this. Thank you.

What exactly is the issue?

I need the helicopter bade to spin in place using script.

And what is wrong with your code? It should rotate the object it is attached to.

5

I need it to spin like a helicopter blade, not move outwards around in a circle

What do you mean, move outwards in a circle? Can you describe what is happening? Also, be aware, you are using the forward vector, perhaps up, would be better.

Edit.
Also, make sure, if you have a child which is the art, to the transform you are rotating, make sure the child is at local position, Vector3.zero.

Not working.

Is there a better method to animate a mesh to simply spin in place?

EDIT
I found a way. i simply change the code line to this:

transform.Rotate(Vector3.down * Time.deltaTime * 100);

and attached the blade to a parent object to act as a roter

thanks for your input

No worries.
