Color array
Sep 2nd, 2009, 11:05am  
well i've been trying to make a Color array and i've searched in this forum and i got to this:
Code:

 color[] mycolours = {color(215,161,44),color(11,17,3),color(32,75,8),color(86,138,20),color(56,108,12),color(247,94,43),color(150,105,17),color(44,45,9),color(236,59,25),color(246,130,49),color(114,59,13),color(97,100,25),color(146,133,23),color(127,160,40),color(173,70,16),color(203,90,27)};
 
 void setup(){
   smooth();
   size(800,600);
 }
 
 void draw(){


   println(cor);
//   fill();
   rectMode(CENTER);
   rect(width/2,height/2,400,400);
 }


so what i want now is to apply colors randomly to the fill. I tried to make the array a string array, I tried color cor =  mycolours[(int)random(mycolours.length))]; i tried a lot of things :S can someone explain to me how to do this?

Looks like you were more or less on the right track.  The array works fine, so must have been something to do with how you tried referencing it:

Code:
 color[] mycolours = {color(215,0,0),color(11,17,3),color(32,75,8),
					  color(86,138,20),color(56,108,12),color(247,94,43),
					  color(150,105,17),color(44,45,9),color(236,59,25),
					  color(246,130,49),color(114,59,13),color(97,100,25),
					  color(146,133,23),color(127,160,40),color(173,70,16),
					  color(203,90,27)};

 void setup(){
   // size should always be the first statement in setup
   // it wasn't a problem in this case but it's a good habit to get into
   size(800,600);
   smooth();
   // slow things down a little so you can see changes happening...
   frameRate(1);
 }
 
 void draw(){
   // You can pass the colour direct to fill like this
   // fill(mycolours[(int) random(mycolours.length)]);
   // or to make it a little clearer:
   color myColour = mycolours[(int) random(mycolours.length)];
   fill(myColour);
   rectMode(CENTER);
   rect(width/2,height/2,400,400);

 }
