Add Some Colour To My Life Apr 7th, 2010, 3:17pm   The following code will generate a random circle in a random position, but won't seem to add a colour to the circle. Can anyone help in doing this? Code: boolean paused = true; float x1; float y1; float c1; void setup() { size(400,400); background(255); smooth(); x1 = random(400); y1 = random(400); color c1 = color(102, 102, 0); } void draw() { fill(c1); background(255); ellipse(x1,y1,20,20); } void keyPressed() { paused = !paused; if(paused) noLoop(); else loop(); }

Re: Add Some Colour To My Life Reply #1 - Apr 7th, 2010, 8:02pm   That's because you declared c1 as a float and then later on tried to declare it as a colour. I'm surprised the compiler doesn't pick this up. Here's the amended program: Code: boolean paused = true; float x1; float y1; color c1; void setup() { size(400,400); background(255); smooth(); x1 = random(400); y1 = random(400); c1 = color(102, 102, 0); } void draw() { fill(c1); background(255); ellipse(x1,y1,20,20); } void keyPressed() { paused = !paused; if(paused) noLoop(); else loop(); }

I think its being overridden by the declaration in setup() and then its discarded as soon as setup ends. So then you have yet again the global unassigned float value. So technically it's legit.
