I want to do the mileometer calculation with on a mouse.

I want to do the mileometer calculation with on a mouse.

Hello. English is cramped because it is not good.
I'm sorry.
Please explain Japanese can be spoken in Japanese.

It is a situation that is shining at random now though I want to make the dot that shines reacting on the mouse extend like the ripple.
I want to calculate the distance with a present mouse cursor.
It shines frequently, it shines few when it is far, and I want to make it to feeling of disregard when it is further if the position of the cursor is near.
Such tentative present ↓ ..feeling it..

---------------------------------

void setup() {
size(800, 800);
colorMode(RGB);
background(20,1,55);
noStroke();
smooth();
frameRate(16);
}

void draw() {
int box_height =20;
int box_width = 20;
int base_color = 100;
int y_color = 100;

for(int i=0;i<50;i++){
for(int j=0;j<50;j++){
int e = int(random(5));
switch(e){

case 2:
float r_color = random(8,y_color);
fill(base_color + r_color,10,40);
ellipse(j*box_width, i*box_height, box_width, box_height);
break;
}
}
}
}

Try this.

string

void draw()
{
int box_height =20;
int box_width = 20;
int base_color = 100;
int y_color = 100;

for(int i=0;i<50;i++)
{
    for(int j=0;j<50;j++)
    {
      float distance = dist(j * box_width, i * box_height, mouseX, mouseY);
      fill(255 - distance, 10, 40);
       //fill(base_color + r_color,10,40);
      ellipse(j*box_width, i*box_height, box_width, box_height);
    }
}
}

Thank you for answering my question.

I changed your program a little in my own way.
In addition, do not you not come to shine from the center like circle?
It doesn't move well though it wants to shine at random, and the character of random was put.
The picture is an image.

--------------------------------------------------------------------

void setup() {
size(800, 800);
colorMode(RGB);
background(20,0,55);
noStroke();
smooth();
frameRate(24);
}

void draw()
{
int box_height =20;
int box_width = 20;
int base_color = 800;
int y_color = 800;

for(int i=0;i<50;i++)
{
    for(int j=0;j<50;j++)
    {
       int e = int(random(5));
       float r_color = random(8,y_color);
      float distance = dist(j * box_width, i * box_height, mouseX, mouseY);
      fill(250 - distance, 10, 40);
       //fill(base_color + r_color,10,40);
      ellipse(j*box_width, i*box_height, box_width, box_height);

      }


}
}

I think you want something like:

int box_height = 20;
int box_width = 20;
int base_color = 50;
int y_color = 200;
int row_nb, col_nb;
float max_dist;
void setup() {
size(800, 800);
colorMode(RGB);
background(20, 1, 55);
noStroke();
smooth();
frameRate(16);
row_nb = height / box_height;
col_nb = width / box_width;
max_dist = sqrt(width * width + height * height);
}
void draw() {
background(0);
for (int c = 0; c < col_nb; c++) {
for (int r = 0; r < row_nb; r++) {
float e = random(1);
float distance = dist(c * box_width, r * box_height, mouseX, mouseY) / max_dist;
if (distance < 0.2 && e < 0.5) {
fill(base_color + random(8, y_color / 2) + 2.5 * y_color * (0.2 - distance), 10, 40);
ellipse(c * box_width, r * box_height, box_width, box_height);
}
}
}
}
