Is there a way to import .txt text to RG.getText (Geomerative)?

in Programming Questions • 2 months ago

This is the example code:

Copy code

grp = RG.getText("Hello world!", "FreeSans.ttf", 72, CENTER);

and I would like to replace "Hello world!" with text from a .txt file.

Is this possible?

Take a look @ loadStrings()'s reference:

thanks for the answer,

I've tried it already and I understand, that loadStrings(); would be the perfect solution.

But when I try to use it with text(); or RG.getText(); it's not working.

this is a simple loadStrings code:

Copy code

String[] txt = loadStrings("/Users/rjth/Desktop/data.txt");
println("there are " + txt.length + " lines");
println(txt);

when I add text(); to this, error message comes up:

Copy code

String[] txt = loadStrings("/Users/rjth/Desktop/data.txt");
println("there are " + txt.length + " lines");
println(txt);
text(txt, 1, 1);

error: The method text(char[], int, int float, float) in the type PApplet is not applicable for the arguments (String[], int, int)

maybe I misunderstood something completely fundamental, but I just don't get it.

what am I doing wrong?

Function loadStrings() gets us not a single whole String, but an Array of String -> String[].
Re-read its reference to grasp it better.

Now, if you wanna glue a String[] into 1 String; use function join().
This way, you can use it directly in text() w/o accessing each String element of an Array 1 by 1.
