drawing a predefined shape every x amount of pixel Oct 23rd, 2007, 1:21am   hi, in effect i would like to create a grid that contains a predefined shape (a conversion of a cross). how do i set processing to draw this shape / cross for example every 100 pixels across and every 100 pixels down? sorry, i know this should be easy but i am a complete beginner. any help would be greatly appreciated thanks

Re: drawing a predefined shape every x amount of p Reply #1 - Oct 23rd, 2007, 8:28am   a very basic way to achieve this is to use 'for' loops : http://processing.org/reference/for.html Code: void setup() { size(400, 400); background(255); for (int x = 50; x < width; x+= 100) { for (int y = 50; y < height; y+= 100) { drawCross(x, y); } } } // draw a cross at (x, y) : void drawCross(int x, int y) { line(x-2, y, x+2, y); line(x, y-2, x, y+2); }
