Using two different readStringUntil "characters"

Processing Electronics (Arduino, etc.)
5

Well, I was lost after the first 3 replies, however I think I can use an array and index the place of it

Like maybe:

float val[2];
int index = 0;

//given that we are already reading from serial port called "port"...
...
void func(){  //not sure which real function to put in the real code
  input = port.readStringUntil('\n');
  val[index] = input;
  index = index + 1;
  input = port.readStringUntil('\n');
  val[index] = input;
  index = index + 1;
   if (index > 1){
    index = 0;
  }
  pxval = val[0];
  pyval = val[1];
}

...
//another external function here
void draw(){
  background(1);
  stroke(255);
  line(pxval, pyval, val[0], val[1]);
}

Note: being new to Processing and coming from a slight Arduino background, I am still learning.

Another note: I had no time to read the reply you gave, as well as the whole question, due to me having a load of schoolwork. Apologies for any incompetence.

EDIT: I have read a bit of the link within the one you sent me:

I think within my arduino code I should output the accelerometer values with a [0] or [1] appended to it, and from there use readStingUntil. I hope this is solved; I will do some testing but for the meantime if there are any errors you can see, please get back to me

Thank you
