Newbie Question - Neopixel Direction

[mooseload]

New to Arduino and neopixels. I have been using the example sketches in the adafruit.neopixel library and reading online to learn, but this is stumping me and its probably something easy.

All I want to do is reverse the direction of the "simple" neopixel example that lights them from 0 to the end of the strip. I took this :

// The first NeoPixel in a strand is #0, second is 1, all the way up
// to the count of pixels minus one.
for(int i=0; i<NUMPIXELS; i++) { // For each pixel...

// pixels.Color() takes RGB values, from 0,0,0 up to 255,255,255
// Here we're using a moderately bright green color:
pixels.setPixelColor(i, pixels.Color(0, 150, 0));

pixels.show();   // Send the updated pixel colors to the hardware.

delay(DELAYVAL); // Pause before next pass through loop

and changed it to what made sense to me:

for(int i = NUMPIXELS-1 ; i >= 0; i--) { // For each pixel...

but it is not working. Can someone explain/teach a newbie how to fish?

Thank you!

@mooseload

for(int i=0; i<NUMPIXELS; i++)

for(int i = NUMPIXELS - 1; i >=0;i = i-1)

@mooseload

for(int i = NUMPIXELS-1 ; i >= 0; i--)

That should work, you did something else (or didn’t do)

That'll do it. THANKS!
