create an array of predefined colors
Mar 20^th, 2007, 2:12pm

I know this might be done thousand times before, but I didn't found something helpful while searching the discourse and website.

I have 5 predefined rgb color values that I like to use for a particle system.
How can I store them into an array and call them when using fill(); ?

Edit:

I got a basic varaint to work, but I'm not sure if it's the most elegant way.

Code:


    int col;
	
    color[] colarray = new color[5];
 
    colarray[0] = color(100,255,35);
    colarray[1] = color(220,200,85);
    colarray[2] = color(185,65,200);
    colarray[3] = color(0,145,35);
    colarray[4] = color(245,35,200);
	  
    col = color(colarray[(int)random(0,4)]);

    fill(col);

The only excess I can see in it is that you don't need the extra call to colour when extracting info from the array: Code: col = color(colarray[(int)random(0,4)]); // could just be col = colarray[(int)random(0,4)];
