Random scene example
The following example should be placed inside a resident script. Sleep time defines scene keep
time (at least 1 second).
1.
-- number of steps to use, e.g. 3 steps = { 0, 127, 255 }
2. steps = 5
3.
-- number of channels to set
4. channels = 3
5.
-- first channel number
6. offset = 1
7.
8. for i = offset, channels do
9. v = math.random(0, (steps - 1)) * 255 / (steps - 1)
10. DMX.set(i, math.floor(v))
11. end
