Array problem (cube grid)

PoYo

I've been trying to put the boxes in an order like the way in the picture but so far all the attempts failed. I can use some help from here ^^. It works when i just use random position but I need them as a grid.

    myCubes.add(new Cube());
  }

thank you for the help but i still have a small problem :D the spacing couldn't figure out the logic of this part

for (int i = 0; i < 30; i++) {
  for (int j = 0; j < 30; j++) {
    myCubes.add(new Cube( i * 44 + 23, j * 44 + 23));
  }
}

Chrisir

it is a nested for loop which means the outer for loop with i is the columns

and for EACH column we do j rows

so the inner for loop is done multiple times since it is called again and again by the outer for loop

Thus we get a grid.

here we init a new cube and give it its position as parameters x,y:

..........new Cube( i * 44+23, j * 44 +23 )

(the first part is x: i * 44+23, then y)

the 44 is the spacing, the 23 is the distance from screen border

Everything works perfect now :) thank you a lot. Will it be too hard to process if I use 6 different video for each surface as texture ?

Chrisir

No

koogs

Yes

depends on the video. 6 x 4k videos resized onto a tiny cube is a LOT of processing.

PoYo

well the its really hard and laggy :D running 486 videos at once is killing the computer :D I have 32gb ram and amd 10k processor ssd drive yet still hard :D at least i know the code works :D
