hi there i have trying to figure out how to add neopixels to the line of code i have 60 leds and i have in the code i want them to flash random number in code then it will move to my dfplayer to play a random sound i have everything else running expect for the neopixels could anyone help me out or figure this out for me

What exactly is it that needs to figured out? Adafruit NeoPixel is one of (very) few well documented libraries with a liberally commented header. Have you read these? It's often useful to understand how a library works before using it.
Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, 5, NEO_GRBW + NEO_GRBW);
^^^^^^^^^^^^^^^^^^^^
Shoudn't that be NEO_GRBW + NEO_KHZxxx (xxx = 400 or 800)?
yes i have read it i am trying to figure out how to flash the strip to a random flash any number i just cant seem to figure out the code to make them flash in the code when i need them to flash
i have this original code that i am trying to switch out to use neopixels right after the serial.println of flash count is where i am tring to add the neopixels to flash when the serial shows howmany flashes and then i need the neopixels to then flash i hope this is clear
void loop()
{
int flashCount = random (3, 15); // Min. and max. number of flashes each loop
int flashBrightnessMin = 10; // LED flash min. brightness (0-255)
int flashBrightnessMax = 255; // LED flash max. brightness (0-255)
int flashDurationMin = 1; // Min. duration of each seperate flash
int flashDurationMax = 50; // Max. duration of each seperate flash
int nextFlashDelayMin = 1; // Min, delay between each flash and the next
int nextFlashDelayMax = 150; // Max, delay between each flash and the next
int thunderDelay = random (500, 3000); // Min. and max. delay between flashing and playing sound
int thunderFile = random (1, 17); // There are 17 soundfiles: 0001.mp3 ... 0017.mp3
int loopDelay = random (5000, 30000); // Min. and max. delay between each loop
Serial.println();
Serial.print(F("Flashing, count: "));
Serial.println( flashCount );
for (int flash = 0 ; flash <= flashCount; flash += 1) { // Flashing LED strip in a loop, random count
analogWrite(ledPin, random (flashBrightnessMin, flashBrightnessMax)); // Turn LED strip on, random brightness
delay(random(flashDurationMin, flashDurationMax)); // Keep it tured on, random duration
analogWrite(ledPin, 0); // Turn the LED strip off
delay(random(nextFlashDelayMin, nextFlashDelayMax)); // Random delay before next flash
}
Serial.print(F("Pausing before playing thunder sound, milliseconds: "));
Serial.println(thunderDelay);
delay(thunderDelay);
Serial.print(F("Playing thunder sound, file number: "));
Serial.println(thunderFile);
myDFPlayer.playMp3Folder(thunderFile);
delay(1000); // Give the DFPlayer some time
while (digitalRead(busyPin) == LOW) { // Wait for the DFPlayer to finish playing the MP3 file
}
Serial.print(F("Pausing before next loop, milliseconds: "));
Serial.println(loopDelay);
delay(loopDelay);
}
as of right now i can get the neopixels to turn on run program but the pixels dont flash random they just turn on one after the other there suppose to flash random amount of flashes then turn off the code here is what i have now can someone plz help me out
