Help with complicated "Blink Without Delay"

Projects Programming

Not sure if this will work (I am at a work computer) but I'm going to try it when I get back.

//Setup the timing variables
long onInterval = 250;
long offInterval = 100;
long interval = onInterval;

//Track the last time the time was updated
long lastMillis = millis();

//Variable to track where in the pattern we are
int flashPatternStepper = 0;
//Variable to track which pattern is being used
int flashPatternSelect = 0;

//Array of possible flash patterns
int [][] flashPatterns = {{1, 0, 2, 0},
			  {1, 2, 1, 2}};

//Variables to track color selection
char color1 = 'r';
char color2 = 'b';

//Pins for the RGB LED
int redPin = 9;
int greenPin = 10;
int bluePin = 11;

//Normal setup just setting pin modes
void setup()
{
	pinMode(redPin, OUTPUT);
	pinMode(greenPin, OUTPUT);
	pinMode(bluePin, OUTPUT);
}

//loop() only calls the handleLEDs function for now
void loop()
{
	handleLEDs();

	//Code to change values of flashPatternSelect, onInterval, offInterval, color1, and color2
}


void handleLEDs()
{
	//Check to see if lights should be on or off
	if(flashPatterns[flashPatternSelect][flashPatternStepper] == 0)
	{
		interval = offInterval
	}
	else
	{
		interval = onInterval;
	}

	//Check if we need to advance flashPatternStepper to the next place in the sequence
	if(millis() - lastMillis > interval)
	{
		lastMillis = millis();
		flashPatternStepper++;
	
		if(flashPatternStepper > flashPatterns.length-1)
		{
			flashPatternStepper = 0;
		}
	}

	//colorSelect decides which LED Pins should be active, if any
	colorSelect();
}

//Control the colors
void colorSelect()
{
	char colorChoice;

	///Set colorChoice based on where we are in the sequence
	switch (flashPattern[flashPatternSelect][flashPatternStepper])
	{
		case 1:
			colorChoice = color1;
			break;

		case 2:
			colorChoice = color2;
			break;

		case 0:
			colorChoice = 'o';
			break;
	}

	//Actually turn on/off the LED pin(s)
	switch(colorChoice)
	{
	    	case 'y':     
      			digitalWrite(redPin, LOW);
      			digitalWrite(greenPin, LOW);
	      		digitalWrite(bluePin, HIGH);
      			break;

    		case 'w':     
      			digitalWrite(redPin, LOW);
      			digitalWrite(greenPin, LOW);
      			arduino.digitalWrite(bluePin, LOW);
      			break;

    		case 'r':     
      			digitalWrite(redPin, LOW);
      			digitalWrite(greenPin, HIGH);
      			digitalWrite(bluePin, HIGH);
      			break;

    		case 'g':     
     			digitalWrite(redPin, HIGH);
      			digitalWrite(greenPin, LOW);
      			digitalWrite(bluePin, HIGH);
      			break;

    		case 'b':     
      			digitalWrite(redPin, HIGH);
      			digitalWrite(greenPin, HIGH);
      			digitalWrite(bluePin, LOW);
      			break;
	
    		case 'p':     
      			digitalWrite(redPin, LOW);
      			digitalWrite(greenPin, HIGH);
      			digitalWrite(bluePin, LOW);
      			break;

    		case 'c':     
      			digitalWrite(redPin, HIGH);
      			digitalWrite(greenPin, LOW);
      			digitalWrite(bluePin, LOW);
      			break;

    		case 'o':
      			digitalWrite(redPin, HIGH);
      			digitalWrite(greenPin, HIGH);
      			digitalWrite(bluePin, HIGH);
      			break;
  	}
}

Hopefully I can build from this to what I need.
