Why are my angle calculations not working properly?

Question

I am using this code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class HARcieveAngleChanger : MonoBehaviour
{
    private float ha;
    private float HAZ;
    public ConfigurableJoint CJ;
    public Vector3 newanchor;
    public Vector3 newaxis;

    public void OnValueChangedHA(float newValue)
    {
        ha = (HAGrab.HAUpdate);
        UnityEngine.Debug.Log("ha WHAT YO DOING = " + ha);
        HAZ =(float)0.8 * (Mathf.Tan(ha))  ;
        UnityEngine.Debug.Log("HAZ WHAT YO DOING = " + HAZ);
        transform.position = new Vector3(0,0, HAZ);
        newanchor.y = (float)-8;
        newanchor.z = -HAZ;
        newaxis.y = (float)8;
        newaxis.z = HAZ;
        CJ.connectedAnchor = newanchor;
        CJ.secondaryAxis = newaxis;


    }

}

From the debug.log(ha), I am getting 45 when I enter a 45 value into the input UI. The HAGrab code gets this. However, the value outputted for HAZ always comes out incorrect (i.e. using trig TOA, tan(angle)*length of alternate side = opposite side, with a 45 degree angle it should come out as 0.8)...

Does anyone have any ideas for why this is the case?

Answer 1

To convert degrees to radians, you need to multiply the angle in degrees by Mathf.PI / 180.0f.

HAZ = (float)0.8 * Mathf.Tan((ha * Mathf.PI) / 180.0f);
