Delay in Generating Moving Boxes

Processing Coding Questions
21

Oh, okay. Thank you very much! That solution seems to have worked.

I have one more question. Is there anyway to delete a previous box?

EDIT: Nvm, I figured it out.

EDIT 2:

New question. Sorry.

Why is it that with this code, my framerate isn’t bumping like it is supposed to.

import java.util.*;
import processing.serial.*;
float x, y1;
float y;
Random ran = new Random();
int pOrM, score = 0;
float fr = 30;
String st = "Press Any Key";
final int stateWaitBeforeProgram = 0;
final int stateNormalProgram = 1;
int state = stateWaitBeforeProgram;

void setup() {
  frameRate(fr);
  size(600, 600, P2D);
  strokeWeight(4);
  if (state == stateWaitBeforeProgram){
    x = -3;
  }
  y1 = ran.nextFloat();
  y = ran.nextFloat() * 570;
}

void draw() {
  if (state == stateWaitBeforeProgram){
    text(st, 260, 290);
  } else {
    noCursor();
    background(204);
    fill(0);
    text(score, 15, 30);
    textSize(26);
    line(mouseX, mouseY, pmouseX, pmouseY);
    rect(x, y, 30, 30);
    if (x < mouseX && x + 30 > mouseX && y < mouseY && y + 30 > mouseY){
      System.exit(0); 
    }
    if (x + 15 > 601){
      if (x < 597){
        score++;
        x = -100;
        fr += 5;
        setup();
      }
    }
    translate(x, y1);
    x += 10;
  }
  
}

void newFunc(){
    fr += 10;
    setup();
}

void keyPressed(){
   if (state == stateWaitBeforeProgram){
      state = stateNormalProgram; 
   }
}

Within the for loop where I bump fr and recall setup(), the first two lines of code initiate. However, neither the frame bump nor the call for setup() work. Why is this?

You shall not call setup ().

Especially the size command does a lot behind the scenes

Instead increase the speed of the ball

This is my current program:

import java.util.*;
float x, y1, x1;
float y;
Random ran = new Random();
int pOrM, score = 0, rectX, rectY;
float fr = 30;
String st = "Press Any Key";
final int stateWaitBeforeProgram = 0;
final int stateNormalProgram = 1;
int state = stateWaitBeforeProgram;

void setup() {
  frameRate(fr);
  size(600, 600, P2D);
  strokeWeight(4);
  if (state == stateWaitBeforeProgram){
    x = -3;
  }
  y1 = ran.nextFloat();
  y = ran.nextFloat() * 570;
}

void draw() {
  if (state == stateWaitBeforeProgram){
    text(st, 260, 290);
    x1 = 0;
    rectX = 30;
    rectY = 30;
  } else {
    noCursor();
    background(204);
    fill(0);
    text(score, 15, 30);
    textSize(26);
    line(mouseX, mouseY, pmouseX, pmouseY);
    rect(x, y, rectX, rectY);
    if (x < mouseX && x + 30 > mouseX && y < mouseY && y + 30 > mouseY){
      System.exit(0); 
    }
    if (x + 15 > 601){
      if (x < 601){
        score++;
        x = -100;
        y = ran.nextFloat() * 570;
        x1 += .5;
        rectX += 2;
        rectY += 2;
      }
    }
    translate(x, y1);
    x += 10 + x1;
  }
  
}

void keyPressed(){
   if (state == stateWaitBeforeProgram){
      state = stateNormalProgram; 
   }
}

My program, however, freezes after 16 points. Is there any way to fix this??

Sure.

This is causing the sketch to exit: System.exit(0);

Your sketch stopped to show rects

Also, even without this line, your sketch stopped to show rects.

That was because :

 if (x + 15 > 601) {
      if (x < 601) {

because when x1 was quite high, this line: x += 10 + x1; led to a jump when increasing x that x was beyond 601. So the condition was not met anymore.

So better :

 if (x + 15 > 601) {
      // if (x < 601) {

Full sketch:


import java.util.*;

float x, y1, x1;
float y;
Random ran = new Random();
int pOrM, score = 0, rectX, rectY;
float fr = 30;
String st = "Press Any Key";
final int stateWaitBeforeProgram = 0;
final int stateNormalProgram = 1;

int state = stateWaitBeforeProgram;

void setup() {
  frameRate(fr);
  size(600, 600, P2D);
  strokeWeight(4);
  if (state == stateWaitBeforeProgram) {
    x = -3;
  }
  y1 = ran.nextFloat();
  y = ran.nextFloat() * 570;
}

void draw() {
  if (state == stateWaitBeforeProgram) {
    background(204);
    text(st, 260, 290);
    x1 = 0;
    rectX = 30;
    rectY = 30;
  } else if (state == stateNormalProgram) {
    background(204);
    fill(0);
    text(score, 15, 30);
    textSize(26);
    line(mouseX, mouseY, pmouseX, pmouseY);
    rect(x, y, rectX, rectY);
    if (x < mouseX && x + 30 > mouseX && y < mouseY && y + 30 > mouseY) {
      // System.exit(0);
    }
    if (x + 15 > 601) {
      //if (x < 601) {
      println("here"+millis());
      score++;
      x = random(-120, -80);
      y = ran.nextFloat() * 570;
      y = random(570); 
      x1 += .5;
      rectX += 2;
      rectY += 2;
      //  }
    }
    //  translate(x, y1);
    x += 10 + x1;
  } else {
    // Error
    println("Error 317"); 
    exit();
  }//else 
  //
}

void keyPressed() {
  if (state == stateWaitBeforeProgram) {
    state = stateNormalProgram;
    noCursor();
  }
}
