This line should set the background colour:
ledData += bytearray((0, 0, 0))
I think I have a modified version somewhere which once the leds were mostly full would then randomly set them back to the background.
Unfortunately I have not made it yet ... if you still have a template, that would be great!

Thanks for the replay...
I will try it if it works ...
Hello everybody
Maybe someone can help me here. I'm trying to adjust the effect sparks.py. I would like a static color as a background and single points which light up randomly. Unfortunately I had no success so far.
Can someone give me a hint?
Thank you very much...
The original sparks.py:
import hyperion, time, colorsys, random
# Get the parameters
rotationTime = float(hyperion.args.get('rotation-time', 3.0))
sleepTime = float(hyperion.args.get('sleep-time', 0.05))
brightness = float(hyperion.args.get('brightness', 1.0))
saturation = float(hyperion.args.get('saturation', 1.0))
reverse = bool(hyperion.args.get('reverse', False))
color = list(hyperion.args.get('color', (255,255,255)))
randomColor = bool(hyperion.args.get('random-color', False))
# Check parameters
rotationTime = max(0.1, rotationTime)
brightness = max(0.0, min(brightness, 1.0))
saturation = max(0.0, min(saturation, 1.0))
# Initialize the led data
ledData = bytearray()
for i in range(hyperion.ledCount):
ledData += bytearray((0, 0, 0))
# Start the write data loop
while not hyperion.abort():
ledData[:] = bytearray(3*hyperion.ledCount)
for i in range(hyperion.ledCount):
if random.random() < 0.005:
if randomColor:
rgb = colorsys.hsv_to_rgb(random.random(), 1, 1)
for n in range(3):
color[n] = int(rgb[n]*255)
for n in range(3):
ledData[i*3+n] = color[n]
hyperion.setColor(ledData)
time.sleep(sleepTime)
