I am trying to build a square that collapses in on itself. I have used beginShape as the means of building a square that when a mouse is pressed will fold its corners down to the center, that is the goal.

I have a button created that when pressed is supposed to create a number of iterators in the draw loop which pull the corners in slowly right now.

i am getting an error that my arguments are not applicable to my method and i could use some clarity as to how to build this function so that when the mouse is pressed the corners converge ... i will take care of stopping them at the center later but if you could help me bring the corners in i would appreciate it.

float x1 = 25;
float x2 = 250;
float x3 = 475;
float x4 = 475;
float x5 = 475;
float x6 = 250;
float x7 = 25;
float x8 = 25;
float y1 = 25;
float y2 = 25;
float y3 = 25;
float y4 = 250;
float y5 = 475;
float y6 = 475;
float y7 = 475;
float y8 = 250;
boolean square = true;




void setup() {
  size(500,500);
}

void draw() {
  mousePressed();
 squareText();
verticeSquare();
}

void squareText(float x1, float y1,float x2, float y2,float x3, float y3,float x4, float y4, float x5, float y5,float x6, float y6,float x7, float y7,float x8, float y8){
  if (square) {
   
float x1 = 25;
float x2 = 250;
float x3 = 475;
float x4 = 475;
float x5 = 475;
