Raycast not working

Questions & Answers

void Update()
{
Ray ray = GetComponent().ViewportPointToRay(new Vector3(0.5F, 0.5F, 0));
RaycastHit hit;
if (Physics.Raycast(ray, out hit))
{
print(hit.transform.name);
if (hit.distance <= 20 && hit.transform.CompareTag(“Interactable”))
{
text.text = hit.transform.GetComponent().GetDescription();
actionGfx.SetActive(true);
print(“hit”);
}
else
{
actionGfx.SetActive(false);
text.text = “”;
}
}
}

Code looks fine to me, but for some reason it is creating some issues.
The Raycast is fine, and can hit objects and retrieve their names.
Line 7 runs, and prints the correct name of the object. However, for some reason nothing else runs inside the if condition. I even replaced the “hit.distance <= 20 && hit.transform.CompareTag(“Interactable”)” with “5 < 7” and the results are the same. Does anyone have any idea why everything is being ignored? Comment/reply for any questions regarding this, thanks.

also print the distance on the same line as print(hot.transform.name) and print hit.transform.tag and you’ll have a lot more information to figure out what is going wrong.
Even easier… use the debugger and put a breakpoint on the print(hit.transform… line, and then just look at all the variables in the debugger and you’ll see what it hit, how far, etc…
You can also step through one line at a time, to see if it goes inside the If… or not
Check your tag name matches a real tag also (check the case sensitivity)

Extracting the body of the Physics.Raycast conditon to a seperate method fixed the issue.
Here’s what it looks like now:

    // Update is called once per frame
    void Update()
    {
        Ray ray = GetComponent<Camera>().ViewportPointToRay(new Vector3(0.5F, 0.5F, 0));
        RaycastHit hit;
        if (Physics.Raycast(ray, out hit))
        {
            CheckRayValues(hit);
        }
        else
        {
            point.SetActive(false);
            description.text = "";
        }
    }

    // Raycast function
    private void CheckRayValues(RaycastHit hit)
    {
        if (hit.distance <= 1.5 && hit.transform.CompareTag("Interactable"))
        {
            point.SetActive(true);
            description.text = hit.transform.GetComponent<Interactable>().GetDescription();
            print(hit.distance);
        }
        else
        {
            point.SetActive(false);
            description.text = "";
        }
    }

Not sure what the difference between extracting the method and not makes, but I guess it was needed here.
