random move in a grid
i have a square shape 40 by 40.
i want it randomly appear inside my grid, my composition is 1080px by 200px.
the grid is a by multiple of 40.the random function will generate multiple of 40.
at the moment it appearing with no order.
holdTime = .3; //time to hold each position (seconds)
minVal = [0 , 0];
maxVal = [1080, 200];
seed = Math.floor(time/holdTime);
seedRandom(seed,true);
random(minVal,maxVal); -

This should work:
holdTime = .3; //time to hold each position (seconds)
numCols = 27;
numRows = 5;
seed = Math.floor(time/holdTime);
seedRandom(seed,true);
col = Math.floor(random(numCols));
row = Math.floor(random(numRows));

i want to be able to customize it for other size
1-
example change the code for comp size of 40×40
and a grid of 10 pixel
2-
be able to control the section of the random exaple bettween the col 10 and 15
it not working
what did i do wrongv = 40; //grid size
a = 2; //mincol 0
b = 3; //maxcol 27
c = 2; //minrow 0
d = 3; //maxrow 5
num = random ( 0.1, 0.5); //speedholdTime = num; //time to hold each position (seconds)
seed = Math.floor(time/holdTime);
seedRandom(seed,true);
col = Math.floor(random(a,b));
row = Math.floor(random(c,d));
[col*v+(v/2),row*v+(v/2)] -
Like this, I think:
v = 40; //grid size
a = 2; //mincol 0
b = 3; //maxcol 27
c = 2; //minrow 0
d = 3; //maxrow 5
seedRandom(index,true);
holdTime = random ( 0.1, 0.5); //speed
seed = Math.floor(time/holdTime);
seedRandom(seed,true);
col = Math.floor(random(a,b+1));
row = Math.floor(random(c,d+1));
