Nov 2, 2018 · I'm trying to make a grid of squares that change their fill (from black to white and vice-versa) when clicked. I'm able to turn the entire grid on or off currently, but I'm unable to figure out how to specify which particular square should be …

Jul 16, 2021 · I get it to make each row of tiles appear one by one by a combination of frameCount and modulo in the nested loop.... but how to let each tile appear after another? I've tried using the same method on the x-axis loop - this makes the grid appear from LEFT/UP to RIGHT/DOWN....

Here is code that draws the rectangle in red by changing its coordinates, then draws it in blue by moving the grid. The rectangles are translucent so that you can see that they are (visually) at …

I'm wanting to create a grid where each square is clickable, however there are a few features that I'm not sure how to implement. Firstly, when a square is clicked I want it to change to black, then the squares that surround the coloured square to change to yellow - kind of like edge detection.

class Pacman { // ... void move(){ float px = x, py = y; x+=dx[direction]; y+=dy[direction]; if( onBarrier() ){ x = px; y = py; } } boolean onBarrier(){ // Check your grid. Is the position (x,y) on a barrier?

Hi, I'm new to processing and I'm trying to create a grid of rectangles that flash different colors at random intervals. Here's my code: size(size, size); for (int i = 0; i < tileNumber; i++) { for (int j = 0; j < tileNumber; j++) { tileField[i] = new tile(i * tileSize, j * tileSize, 255, 255, 255, 5); background(0);

Mar 14, 2021 · By default 0,0 is the top left corner. X increases as you go right, Y increases as you go down. You can move the origin with translate. You can flip the values using scale.

Oct 3, 2013 · I am trying to create a Cartesian Grid using a for loop. Below is part of my code so far; when I run it, it does not make a series of lines, but rather it produces a window that has what appears to be a white panel and it slows down my computer considerably.

Jul 15, 2020 · This was a little project to generate arragements of tiles on a grid - think placing tetris blocks down in endless random arrangements, without having anything overlap. I used Java / Processing, and this involved implementing a grid-based procedural generation algorithm.
