Question about box() and movement

in Programming Questions • 1 year ago

Hello,

I wrote a sketch which draw a box consist of boxes, here is my code (do not pay attention to comments in russian)

import processing.opengl.*;
int boxSize = 40; //размер кубика
int boxCount = 10; //Кол-во кубиков на сторону
int[] k = {0,0,1,2,3,4,5,6,7,8,9}; //хитрые коэф для ебаного транслэйта
int wndW = 800; //Ширина окошка
int wndH = 800; //Высота окошка
void setup()
{
size(wndW, wndH,OPENGL);
background(0);
smooth();
frameRate(10);
noFill();
stroke(255);
// noStroke();
}
void draw()
{
background(0);
translate (wndW/2-boxSize*boxCount/2,wndH/2-boxSize*boxCount/2,0); //Центруе кубик в окне
for (int x=0;x<boxCount;x=x+1)
{
translate(x*boxSize-k[x]*boxSize,0,0);
for (int y=0;y<boxCount;y=y+1)
{
translate(0,y*boxSize-k[y]*boxSize,0);
box(boxSize);
}
translate(0,-1*(boxSize*boxCount-boxSize),0);
}
//boxSize=boxSize+1;
}

Next I want animate random box in this big box, for example it will fly away in any direction. I can`t imagine how I can do so only with translate function, is there any way how I can draw boxes setting it coordinates like a 2D rectangle? I really stuck.

You should create an array to store boxes coordinates (PVector[] or float[][]) . That will allow you to act on single boxes and will improve performance, because you won´t need to calculate the position in every frame of the main loop. Then create a method to modify the movement of a random box, acting on the position stored in this array.

Thanks for the answer. Array is a good idea, I will use it, but my main prolem is how can I draw boxes using coordinates?
Can you give me small example of sketch which draw two boxes using coordinates?
