so i am trying to write a code i want to move squares in other squares randomly,there is 10x10 squares. squares move but i dont know my code is true can you help? i cant share the whole code, because its a school project, i just want to know if this makes sense, its something like this (i added particle poisitons because i think thats the whole point and i forgot)
particle_positions = ones(num_of_particles, 2) * num_of_cells / 2 + 0.5
...
move_x = randi([-1, 1]);
...
if xnew < 1
xnew > num_of_cells ;
move_x = -move_x;
end

This doesn't make any sense:
if xnew < 1
xnew > num_of_cells ;
move_x = -move_x;
end
It should be something like
if xnew < 1
% Don't let it go from 1 to 0
xnew = 1;
elseif xnew > num_of_cells
distancePast = xnew - num_of_cells;
xnew = num_of_cells - distancePast;
end

I want the squares to match the squares in the grid.. I used xline yline but its still the same

Then you need to make sure the centers are on the 0.5 locations and go from the integer less than that to the integer more than that.
