Chaser: Setting color of one spot without changing color of the other ones

[Codeman]

Hi all,

I am new to QLC+ and I think I have some lackage of knowledge of the whole system - sorry for that!

I have a simple problem and don't know how to solve it:
I have four RGBW spots for a showcase lightning and I want to change the color of only one spot at a step, e.g.

1. Spot1, Spot2, Spot3, Spot4: fade to white
2. Only Spot1 fade to a random RGB color - all others have to stay white
3. Now additionaly Spot3 fades to a random RGB color
4. Spot1, Spot2, Spot3, Spot4: fade to white
5. Only Spot2 fade to a random RGB color
6. Now additionaly Spot4 fade to a random RGB color
7. Goto Step1

I tried to do this with a chaser with scenes and scripts. The only way for random colors seems to use a script. So I made 4 scripts - one for each spot e.g.:

Code: Select all

setfixture:1 ch:0 val:255 // 1R, Dimmer
setfixture:1 ch:1 val:random(0,255) // 1R, Red
setfixture:1 ch:2 val:random(0,255) // 1R, Green
setfixture:1 ch:3 val:random(0,255) // 1R, Blue
setfixture:1 ch:4 val:0 // 1R, White

Also I made scenes for every spot showing white color. The problem is that every step of the chaser sets all other values to 0 - so all white spots from the previosly step (which were white) are sudenly black.

A solution may be to set all other spots in the script to white color but this is not very comfortable when adding more elements to the chaser. Is there another solution for this problem?

Another question: Is there a way to automatic fire up concurrently changes to spots, e.g. starting changing the color of two spots to a random color at the same time but with different fade times? With fixed colors I think this can be done in a scene. But how do I do this with random colors?

Thanks a lot,

Holger
