Need help inserting a strobe effect into the beginning of an existing neopixle code

[tiogar]

Greetings,

Making a super saiyen effect for a costume, so id like the neopixles I'm using to do a strobe effect when they first come on, then repeat a chase code indefinitely. I had c+ 20 years ago...but my coding is made of rust. lol

This is the code I found for the chase effect...I thought about just putting the strobe in setup, but it just made everything stop working.

#include <Adafruit_NeoPixel.h>
#define PIN 6
#define NUM_LEDS 60
// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
//   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
//   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
//   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products)
//   NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  strip.begin();
  strip.show(); // Initialize all pixels to 'off'
}

void loop() {
  RunningLights(0xff,0xff,0x00, 50);
}

void RunningLights(byte red, byte green, byte blue, int WaveDelay) {
  int Position=0;
 
  for(int j=0; j<NUM_LEDS*2; j++)
  {
      Position++; // = 0; //Position + Rate;
      for(int i=0; i<NUM_LEDS; i++) {
        // sine wave, 3 offset waves make a rainbow!
        //float level = sin(i+Position) * 127 + 128;
        //setPixel(i,level,0,0);
        //float level = sin(i+Position) * 127 + 128;
        setPixel(i,((sin(i+Position) * 127 + 128)/255)*red,
                   ((sin(i+Position) * 127 + 128)/255)*green,
                   ((sin(i+Position) * 127 + 128)/255)*blue);
      }
     
      showStrip();
      delay(WaveDelay);
  }
}

void showStrip() {
 #ifdef ADAFRUIT_NEOPIXEL_H
   // NeoPixel
   strip.show();
 #endif
 #ifndef ADAFRUIT_NEOPIXEL_H
   // FastLED
   FastLED.show();
 #endif
}

void setPixel(int Pixel, byte red, byte green, byte blue) {
 #ifdef ADAFRUIT_NEOPIXEL_H
   // NeoPixel
   strip.setPixelColor(Pixel, strip.Color(red, green, blue));
 #endif
 #ifndef ADAFRUIT_NEOPIXEL_H
   // FastLED
   leds[Pixel].r = red;
   leds[Pixel].g = green;
   leds[Pixel].b = blue;
 #endif
}

void setAll(byte red, byte green, byte blue) {
  for(int i = 0; i < NUM_LEDS; i++ ) {
    setPixel(i, red, green, blue);
  }
  showStrip();
}

Does this do what you want? It compiles, blinks on-board LED but otherwise untested:

#include <Adafruit_NeoPixel.h>
#define PIN 6
#define NUM_LEDS 60
// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
//   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
//   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
//   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products)
//   NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)

I can see the video, but please tell me in actual words what you want. Just saying "strobe" doesn't tell me anything.

@Blackfin It did! a few quick tweeks and it worked perfectly. Wasnt ready for the con, but that was an unrelated issue.
