Help Wanted - Trying to replace text but stuck at returning it

[AyProductions]

I tried using the Java String Replace() function to replace some text. But I can't return it because it is a function. I tried returning it anyway but it didn't compile. I tried looking at the Builtin Text blocks source, but it was in JS. I am having trouble returning the replaced text.

This is a test extension I am making to test some things out...

So my question how do I return it. I apologize if this is a really basic question...
I am still a novice in Java...
Thanks in advance.

Show your java code what you are trying to do.

[AyProductions]

@SimpleObject(description = "Replaces text")
    public void ReplaceText(String txt, String fr, String to){
        return txt.replace(fr, to).toString();
        // return added for testing, and to return the text
        // tostring added for debugging
    }

It does not return, probably because it is a function, so main goal is how to return it?

@SimpleFunction(description = "Replaces text")
    public String ReplaceText(String txt, String fr, String to){
        return txt.replace(fr, to).toString();
        // return added for testing, and to return the text
        // tostring added for debugging
    }

Ok and one more thing, how do I put the text in a label or variable or textbox?
That's why I tried using @SimpleObject.

[Patryk_F]

@SimpleFunction(description = "Replaces text")
    public String ReplaceText(String txt, String fr, String to){
        return txt.replace(fr, to);
        // return added for testing, and to return the text
        // tostring added for debugging
    }

To return something from a function, use the return type of the object instead of "void". In your case it is String. And you don't have to use toString(). because replace() returns String.

Understood. Thanks for the advice.

Also, now this error

@AyProductions

how do I put the text in a label or variable or textbox?

?

[Patryk_F]

@SimpleFunction instead of @SimpleObject. I copied your code for editing purposes and did not correct it.

[AyProductions]

That would've been the case, if I could compile the extension
Now it won't compile, and I've posted the log

@Patryk_F

@SimpleFunction instead of @SimpleObject

Why do I need to do that? I want to put the text in a label, textbox, or variable, like the replace block in the Blocks Editor.

If I use @SimpleFunction I can't put any text objects like labels textboxes and variables, etc...

I want a block like this

@AyProductions

I want a block like this

@SimpleFunction(description = "Replaces text")
    public String ReplaceText(String txt, String fr, String to){
        return txt.replace(fr, to);
        // return added for testing, and to return the text
        // tostring added for debugging
    }

The block will be purple, just like Tim showed.
There is no @SimpleObject annotation for functions. You can only use @SimpleFunction, @SimpleProperty or @SimpleEvent. @SimpleObject is something completely different.

Thank you for the solution Patryk! It worked, and I actually learned something today.
