TMP variable to TEXT

Unity Engine
1

Hi all,

I am trying to set a TMP object to the same value as an INT. When the player collides with an object, this value will rise and will be seen on screen as the TMP element.

public class TRIGGERENTER : MonoBehaviour
{
    public TMP_Text TEXT;
    public int valueNumber;



    // Start is called before the first frame update
    void Start()
    {
    

        TEXT.text = TEXT.ToString();
    }

    // Update is called once per frame
    void Update()
    {
   
    }

    private void OnTriggerEnter(Collider other)
    {
      
        TEXT.SetText(TEXT.ToString());

       
 
    }
}

any help is greatly appreciated

thank you

When I collide with the object, the TMP does update but to 'Text(TMP)(tmpro.textmeshProUGUI)

Shouldn’t you be setting it to valueNumber instead of TEXT.ToString()?

TEXT.text = valueNumber.ToString(); does not work either?

Is my namespace correct or is the variable wrong or something perhaps?

What does your code look like now? You were extremely close in your original post.

public class TRIGGERENTER : MonoBehaviour
{
    public TMP_Text TEXT;
    public int valueNumber;
    // Start is called before the first frame update
    void Start()
    {
  
        TEXT.text = TEXT.ToString();
    }
    // Update is called once per frame
    void Update()
    {
  
    }
    private void OnTriggerEnter(Collider other)
    {
    
        TEXT.SetText(valueNumber.ToString());
      
    }
}

I have cut away most of the other code that is in this script to it is easier to see.

What does it do? And what do you want it to do?

If you want it to increment, you need to add to your valueNumber, and then re-update the text to match the new value.

Basically, the script acts as a way for me to load certain panels and text upon collisions (I have removed this). What I want it to do is every time the player collides with the trigger (this script is applied to the trigger) the TMP element should update, 1,2,3 - I know how to do that, but I can’t seem to get the variable to show in the TMP element (for example when it is set to 1, the text should be 1 too).

And what does it do right now?

When I collide with the object, the TMP does update but to 'Text(TMP)(tmpro.textmeshProUGUI)

Even after you changed to the new code, saved your file, and recompiled your scripts?

Yes, it still says that. I’m not sure how to proceed!

The above makes no sense.

Don’t you mean:

TEXT.text = valueNumber.ToString():

??

Be sure you spend the time to do Step #2 below, otherwise you’re just a monkey typing random stuff on the keyboard.

Tutorials and example code are great, but keep this in mind to maximize your success and minimize your frustration:

How to do tutorials properly, two (2) simple steps to success:

Step 1. Follow the tutorial and do every single step of the tutorial 100% precisely the way it is shown. Even the slightest deviation (even a single character!) generally ends in disaster. That’s how software engineering works. Every step must be taken, every single letter must be spelled, capitalized, punctuated and spaced (or not spaced) properly, literally NOTHING can be omitted or skipped.

Fortunately this is the easiest part to get right: Be a robot. Don’t make any mistakes.
BE PERFECT IN EVERYTHING YOU DO HERE!!

If you get any errors, learn how to read the error code and fix your error. Google is your friend here. Do NOT continue until you fix your error. Your error will probably be somewhere near the parenthesis numbers (line and character position) in the file. It is almost CERTAINLY your typo causing the error, so look again and fix it.

Step 2. Go back and work through every part of the tutorial again, and this time explain it to your doggie. See how I am doing that in my avatar picture? If you have no dog, explain it to your house plant. If you are unable to explain any part of it, STOP. DO NOT PROCEED. Now go learn how that part works. Read the documentation on the functions involved. Go back to the tutorial and try to figure out WHY they did that. This is the part that takes a LOT of time when you are new. It might take days or weeks to work through a single 5-minute tutorial. Stick with it. You will learn.
Step 2 is the part everybody seems to miss. Without Step 2 you are simply a code-typing monkey and outside of the specific tutorial you did, you will be completely lost. If you want to learn, you MUST do Step 2.

Of course, all this presupposes no errors in the tutorial. For certain tutorial makers (like Unity, Brackeys, Imphenzia, Sebastian Lague) this is usually the case. For some other less-well-known content creators, this is less true. Read the comments on the video: did anyone have issues like you did? If there’s an error, you will NEVER be the first guy to find it.

Beyond that, Step 3, 4, 5 and 6 become easy because you already understand!

Neither are we.

Sorry, couldn’t resist :smile:

I’d guess your OnTriggerEnter() is never executed and you have not updated your code in your OnEnable(). Thus no change is visible. Try what Kurt and RadRedPanda suggested. It will help :wink:

Thank you, everyone, for your help - I decided to change the mechanic but your tips have been really useful!

Stay Safe.
