yeah the thing is with param_equal, it can do strings or actions, so while param_bigger doesn't need `` [but still can use] because it can't deal with strings and it uses '' or "" to encapsulate actions that include a space like

param_bigger 'get_var a' 'get_var b'

because param_equal can do strings, then it needs the action to be specified as an action, by wrapping in `` and strings wrapped in "" or ''
It's a little messy as a rule set but to clean it up would remove capabilities.
...script, it's a language, and languages have these weird nuances that a first are confusing but there's usually a reason as to why.
 
Hi. Can a script count the number of letters in a string?
set_var 'a' "text"

How many letters are there in the variable 'a'?
 
setting another var to your first var with param_cast 'text' X, [X being the number of chars to cast] then comparing for equality.
set_var 'a' "text" & set b `get_var a & param_cast 'text' 1` & 
var_equal "a"  "b" ? SIZE OF 1 : 
set b `get_var a & param_cast 'text' 2` & 
var_equal "a"  "b" ? SIZE OF 2 : 
set b `get_var a & param_cast 'text' 3` & 
var_equal "a"  "b" ? SIZE OF 3 : 
set b `get_var a & param_cast 'text' 4` & 
var_equal "a"  "b" ? SIZE OF 4 :


truth be told you don't even need a 2nd var, same sort of idea but with param_equal
param_equal `get_var a` `get_var a & param_cast 'text' 1` ? SIZE OF 1 : 
param_equal `get_var a` `get_var a & param_cast 'text' 2` ? SIZE OF 2 : 
param_equal `get_var a` `get_var a & param_cast 'text' 3` ? SIZE OF 3 : 
param_equal `get_var a` `get_var a & param_cast 'text' 4` ? SIZE OF 4 :

 
Perfect!!!

Thank you !
 
Someone asked for a midnight countdown video effect, but I was thinking that it would maybe be simpler to add it to a video skin
But that will need some scripting
I assume the value could then be taken from comparing 23:59:59 to get_clock cast to maybe an integer, then param_multiply -1 and param_add to get the difference, maybe adding the missing second, and then showing the value?
But I can only figure out how to do the first few steps...
 


I've done it, I just need to remember how I did it.

*edit, I found it and I remember the problem now. It needs to be started at a known time.
[it monitors saved clock state v current clock and if different, -1 from the countdown, some maths, and resave new clock state]
Problem root is, get_clock, it returns a string so it will only cast the hour value as an int [the : breaks it]. And we've got nothing for casting substrings.

get_clock 'hour'
get_clock 'min'
get_clock 'sec'

would be one fix, for this specific problem, but that isn't real script currently.

param_cast 'text' SIZE INDEX

would be another more round about fix, it would have other uses too, but again doesn't exist.

I suppose it could be brute forced to get the time in a usable form but that would be pretty ugly.
[I'll see how it looks]

Or windows I could make a plugin
 
I'll add a countdown script to make this easier
 
thanks that would be good, I've just done the script way anyway.
not easy I suppose I'll post it here in the off chance I need it in the future,
plus to remind myself how to do stuff

I played with it a little bit just see second by second changes, this uses text presets for size font & position, so it will only work if you have them saved ["time","number","message" in my case]
this bit replaces the end bit

( var $showCount 1 ? effect_string text 3 "time" & 
get_var $time3 & param_cast & deck master effect_string 'text' 2 :  ) & 
param_equal `get_var $time3` "00:00:10" ? set $showCount 0 & effect_string text 3 "number" & effect_string text 2 "10" : 
param_equal `get_var $time3` "00:00:09" ? set $showCount 0 & effect_string text 2 "9" : 
param_equal `get_var $time3` "00:00:08" ? set $showCount 0 & effect_string text 2 "8" : 
param_equal `get_var $time3` "00:00:07" ? set $showCount 0 & effect_string text 2 "7" : 
param_equal `get_var $time3` "00:00:06" ? set $showCount 0 & effect_string text 2 "6" : 
param_equal `get_var $time3` "00:00:05" ? set $showCount 0 & effect_string text 2 "5" : 
param_equal `get_var $time3` "00:00:04" ? set $showCount 0 & effect_string text 2 "4" : 
param_equal `get_var $time3` "00:00:03" ? set $showCount 0 & effect_string text 2 "3" : 
param_equal `get_var $time3` "00:00:02" ? set $showCount 0 & effect_string text 2 "2" : 
param_equal `get_var $time3` "00:00:01" ? set $showCount 0 & effect_string text 2 "1" : 
param_equal `get_var $time3` "00:00:00" ? set $showCount 2 & effect_string text 3 "message" & deck master effect_string 'text' 2 "Happy New Year!" &

don't mind me I was just making an edit.

Crazy stuff!
Here is my video on it:

And... we may also need a script that turns it off again, so that the text fx returns to normal :)
 
fast video work :),

yeah I'll make a change or two, one to make on/off on button press & two I'll add a message for Happy new year or whatever,

because we've got everything as variables now, it's a 2nd event scheduler of sorts.

little changes made, I could go mad with this but for actual midnight you want to use the real event scheduler, too many variables of user workflows to have something off the peg suit everybody.
but it can do stuff at any second, the countdown runs in the back ground.
 
Cool!
So it will say Happy new year?
... and if I want something more spectacular, I should use the Event scheduler
 
Hmmm The new script doesn't seem to work.
The text isn't changing
 
sorry. I'll check it

*edit, found it an errant quote and used a local var instead of a global var.
I added a place near the start so when it is running you can change between countdown showing and a generic message,
plus at the end I left a space to have a message after happy new year, [but the effect is turned off then and text effect use is back to normal].

when it's initialising it takes a couple of seconds to brute force the time [it's garbled for a few seconds], so it just says "COUNTDOWN" until it's ready to run smoothly.

I could add stuff to this for days but really it's a case by case, for what people need
 
just consider this a visual count down, it can do stuff for automation like show the counter for a minute every 15 minutes, probably some radio applications too, but the real event scheduler is a bit easier.
 
True, and thank you
I've now replaced the downloadable script in the video
 
Cool
I've updated the script linked in the video
 
Hi
I have always used the "comment" field for remix info because originally VDJ didn't have a 'remix' field to use & I was happy to continue in that vein, however now I am using online content I need the remix field visible.

I have worked out that
browsed_song 'remix' `get_browsed_song 'comment'`
will successfully copy the comment over to the remix field but this only works 1 file at a time.

Is there a quick way I can change, either selected files or all files in a folder, in 1 go.

Basically I need a script to recurse through the list of files & copy the comment field to the remix field.
Any pointers would be appreciated. If this has been covered elsewhere I apologise.
Thanks
 
That would be a repeat_start script [a.k.a. rsi, repeat_start_instant]

probably best if you start out of a filter [advanced] to get all files, something like
filter
Length > 60 and Comment is not ""

button script
browser_scroll 'top' & repeat_start_instant scroller 25ms & browsed_song 'remix' `get_browsed_song 'comment'` & browser_scroll 'bottom' ? repeat_stop scroller : browser_scroll +1



or this to also clear the comment field after it copies over

browser_scroll 'top' & repeat_start_instant scroller 25ms & browsed_song 'remix' `get_browsed_song 'comment'` & browsed_song 'comment' "" & browser_scroll 'bottom' ? repeat_stop scroller : browser_scroll +1


either will take a little while, it processes about 2000 tracks a minute
