Here is some of those threads

<md..a thread on DIYC will probably cause me to do a new effect class for chases.

The thread was here: http://doityourselfchristmas.com/forums/showthread.php?21168-Question-on-using-Nutcracker-to-animate-a-single-strand-of-pixels/page2

it was started by people who want to have a single string along their roofline and be able to get nutcracker effects.

I tried that' date=' still got "division by zero". Screenshot attached, am I doing something wrong? Thanks.[/quote']

DennyMo; you are right it gives an error.

I will look into this.

For now, a workaround is this, if you want a 1x50 roofline, create this:

1 string x 200 pixels

in the effect set display window as 90 degrees

Now it generates 1 string with pixels 1-50 as you desire without giving a divide by zero

I created a rgb target in your account called LINE_SEAN

and an effect called meteors1_sean

here is the result

I was testing this some last night with a single strand (roof line element) with the butterfly effect and it worked great. Didn't think about using the meteor effect for chasing sequences until Sean posted.. very cool!

yep' date=' i think just meteor and butterfly would be good for a single string.

I will build the new effect class called chase and get a dozen or so options on it.

I am thinking

chase with 1,2,3 colors?

color1?

color2?

color3?

how many pixels per color (default 1)? ( I am thinking of things like grouping colors as 3 pixels each, 5 pixels .etc.)

direction? Allow chase to go left to right or right to left

speed? (1=normal speed, .5 twice as slow, 3 = 3 times faster.)

sparkle percentage? (0-100, indicates random pixels set to white)

solid color fades? (Y or N, take color 1 and fade to color 2 over fade duration)

fade duration? (Enter seconds for fade, this is used with the above question)

well, that is just a start for chases

Some more single string effects. Target is 1x200, 4 folds, 90 degree window. This will produce a 1x50 single string

[b']GARLAND effect:

and some more discussion

I few I think would be cool:

Double chase where the chase goes from both ends to the middle and then out to the ends.

Multiple chases where the string is divided up into sections with each section doing the same chase' date=' or different if you like to add that as well. I'd like to specify the break points so they don't all have to be the same length but they stay in sync. This allows an effect on your eves but keeps the different sections of eves doing their own chase in sync with the rest.[/quote']

double chase i was thinking about, i will add it.

multiple chase by dividing into sections sounds cool, ill look into it. shouldnt be hard.

i am thinking of something else.

a batch capablity. You have say 5 strings around your house. You want a different effect on each string (or maybe the same), fill in a table

Batch# target Effect

1 chase garland1

2 chas2 garland1

3 chase3 garland3

4 chase5 fly

now press a button and i will generate 4 runs of nutcracker and then merge the 4 into one output file.

i am working on the target generator where u can change the starting pixel (right now it is always 1). This way if 30 pixels is one eave and 20 is the next you create two targets

chase1 string 1 pixels 1-30

chase2 string 1 pixels 31-50

now you can do things like the butterfly effect on the two and they will be exactly synced in color even though they have different pixel count

seems single string effects could get better and better.

oh well, now i think i need rgb on my eaves.

Always more neat things coming out of the skunkworks. Anyway you can setup a horizontal line configuration for the matrix

Great idea on the roof line and windows!!

(now if there was an easier way to set it up/look at it in Visualizer....)

Great Work Sean!!
