I'm generating a grid of hexagons by using a for loop and I'm having some issues      for (var i=0; i <= rows; i++) {         for (var j=0; j <= cols; j++) {             ctx.save();             ctx.translate(0+i*distX, 0+j*distY);...
Apologies for my complete lack of javascript intuition, but I was wondering if it is possible to change properties of a particles.js object dynamically:  I'm using jQuery to detect when a user moves a slider on the screen (successfully). However,...
