Array of Colors?

beginners
#1

In my first oF app, I’ve got a pool of colors that I’d like to pull from at random. It was super easy when I stored them as hex ints (0xff0000), but I need to fade them out as well, so I had to switch to (255, 0, 0, 127) style.

Coming from AS3, I imagined an array of custom rgbColor objects. Structs in C++ seemed similar to this, so I found an example that I thought would work:

in header:

  
  
struct rgbColor { int r; int g; int b;};  
rgbColor colors[3];

in setup function:

  
  
colors =   
{  
     {65,255,245},  
     {62,192,197},  
     {248,5,96}  
}

This fails with: Expected primary-expression before ‘{’ token
at the opening bracket.

This is the only way I could get it to work:

in header:

  
  
struct rgbColor { int r; int g; int b;};  
rgbColor colors[3];

in setup function:

  
  
rgbColor color0 = {65,255,245};  
rgbColor color1 = {62,192,197};  
rgbColor color2 = {59,129,150};  
  
colors[0] = color0;  
colors[1] = color1;  
colors[2] = color2;

Appreciate any help!

You could try using the ofColor class which has r, g, b and a vars.

In header

  
ofColor colors[3];

**In setup function **

  
  
colors[0] = ofColor(65,255,245);  
colors[1] = ofColor(62,192,197);  
colors[2] = ofColor(59,129,150);
