Please tell me how to put the strings obtained from the text file into the array

Armory Engine Logic Nodes

Hello. please tell me.
I got a string from a text file using the following logical node.

1

This string is separated by spaces or newlines.
I want to put in the array as follows
Input0 = L2
Input1 = R2
Input2 = U’
…

Thank you.

There isn’t a way to do that in nodes right now. If you write just a little Haxe and Python you could make your own node that does it though. Here is an example of a logic_node pack that you could use as a reference if you wanted to make your own node.

If you don’t want to write it yourself, you can open a feature request on GitHub for it.

… and, as various of us solve practical problems that [all of us] face, don’t forget that a “feature request” can certainly include: “and now, here (for better or for worse) is what I wrote …” Who knows, you just might become a Contributor.

Thank you for answering.

I am not good at English so I may not understand exactly what you are saying.
Are you saying that there may be no one to respond to a feature request?
I think that is a matter of course.

Nodes is not my forte, so I did a quick solution in Haxe, you may “port” it to nodes. It manually finds the substrings separated by a space with an iterator. Also take into consideration that this function expects “perfect input” (e.g. a space at the end of the string) so if you don’t add any checks, that may cause some trouble when debugging later.


// https://haxe.org/manual/lf-iterators.html
class MyStringIterator {
  var s:String;
  var i:Int;

  public function new(s:String) {
    this.s = s;
    i = 0;
  }

  public function hasNext() {
    return i < s.length;
  }

  public function next() {
    return s.charAt(i++);
  }
}

function stringDecomp(longString:String){
	// longString = "ab bc cd ef gh ij kl mn op qr st uv wx yz "; example
	var inputs = [];
	var myIt = new MyStringIterator(longString);
	var counter = 0;
	var strAccum = "";
	for (c in myIt)
	{
		if(c != " ")
			strAccum += c;
		else
		{
			// additional checks could be added here to verify that the string retrieved format is correct
			inputs[counter] = strAccum;
			strAccum = "";
			counter++;
		}
	}
	return inputs;
}

I was very helpful for your polite response and I studied. Thank you.
I will try to create a logic node.
