3DBuzz TP Camera ERRORS

Unity Engine

The name `Helper’ does not exist in the current context

TP_Camera = TheCamera

TheCamera Script

Helper script

using UnityEngine;

public static class Helper
{
    public static float ClampAngle(float angle, float min, float max)
    {
        do
        {
            if (angle < -360)
                angle += 360;
            if (angle > 360)
                angle -= 360;
        } while (angle < -360 || angle > 360);

        return Mathf.Clamp(angle, min, max);
    }
}

What is wrong with it.

There’s no actual reference to helper.
Unity only knows you want to use a function called Helper, but has no idea what or where this ‘Helper’ is.

Also, the script file helper resides in is incomplete, try creating an empty script to see the structure and elements unity requires. (Mainly line 4 :wink: )
