Okay so it's actually an echo effect and not a syllable that repeats.

You need something completely different for that, the furigana/multi-highlight syntax isn't designed for that.

Last time I needed to do one, I made a copy of the source line, without any repetition of words in, and timed the duplicate of the line to the echo, then I marked the line so it would get a different effect. It's important here to note that the line with the echo timing still needs to have all of the original line's text in, even if it isn't timed in detail, but the text needs to be there for the positioning to work correctly.

I made up some random timings for the echo text here. The rest is mostly based on the examples from the Inline-fx page in the manual.

Those are just empty syllables inserted to delay things.

I read through this forum and Aegisub and didn't see anyone having this same problem, I apoligize if I missed it.

I've been banging my head against the wall all morning. I'm trying to do a simple rotation effect, which I've done several times before without any trouble. For some reason today it just won't rotate. I've tried everything I could think of, so I'm here to plead for help.

{\alpha&Hff&\an5\t($start,$start,\1a&H00&)\t($start,$end,\frz360)\t($end,$end,\alpha&Hff&)}

It appears and disapears like I want, but no rotation. I've tried it without the alpha effects, adding pos and org tags, and using different rotation values. The most I get is the whole line rotates at the beginning. Thank you for reading this.

[jfs]

Maiku2:
Is that a "line" or a "syl" template? Also, are you doing any retiming?

[Maiku2]

Thanks for getting right back to me jfs.

It's a template line and I've checked the timing, there's nothing wrong with it that I can find.

Edit: The timing is right, but I'd copied the line above and it was a template line and not a template. I changed it to a template and it turns now. Though it's a bit distorted, not just a rotate like I wanted. I'll have to figure what I did to cause that and figure out where my border went.

Thanks again! I knew it was something stupid I just couldn't think of it.

[jfs]

If you want a syllable to rotate around its own centre you must use a "syl" template. If you use a line template as you do now, the centre of rotation for everything on the line will be the origin point of the line, i.e. the middle of the line, which makes for a rather strange effect for the rotation, probably not what you want.

[jofori89]

How can i repeat \t() syl.n times or 10 times for once lines, increase in startadjust & endadjust
Some thing like this
time = line.duration/syl.n
{\frz0\t(0, !1*time!, \frz-5)\t(!1*time!, !2*time!,\frz0)\\t(!3*time!, !3*time!,\frz-5)...}

I mean i want to join all lines (10 lines or more) of the loop to only once line.

code line: rotz = -math.random(1,4)*0.1
template syl loop 10: !retime("preline", (j-1)*(line.duration/10), j*(line.duration/10))!{\k$skdur}{\frz!((j%2)*2-1) == -1 and rotz or -rotz!\fry!((j%2)*2-1) == -1 and rotz*3+10 or -rotz*3+10!\t(\frz!((j%2)*2-1) == 1 and rotz or -rotz!\fry!((j%2)*2-1) == 1 and rotz*3+10 or -rotz*3+10!)\pos($scenter, $smiddle)}

You need to create a helper function in a code line to do that, that's the only way you can use a "for" loop directly, which is what you need to.

I tried this fucntion, it does not work but i dont know how to fix it, what's wrong with the loop?

code line: rotz = -math.random(1,4)*0.1; wind_offset = line.duration/(line.kara.n); function turn() for r=1,line.kara.n do turn = turn .. string.format("\\t(%d,%d,\\frz%d\\fry%d)",wind_offset*(r-1),wind_offset*r,rotz,rotz*3+10) if rotz < 0 then rotz=0 else rotz=-math.random(1,3)*3 end end return turn end; wind = "{"..turn.."}"

template syl: {\an5\pos($scenter, $smiddle)}!wind!

Error

Runtime error in template code: [string "template code"]:1: attempt to concatenate global 'turn' (a function value)
Code producing error: rotz = -math.random(1,4)*0.1; wind_offset = line.duration/(line.kara.n); function turn() for r=1,line.kara.n do turn = turn .. string.format("\\t(%d,%d,\\frz%d\\fry%d)",wind_off set*(r-1),wind_offset*r,rotz,rotz*3+10) if rotz < 0 then rotz=0 else rotz=-math.random(1,3)*3 end end return turn end; wind = "{"..turn.."}"

[jfs]

You're forgetting to put function call parentheses onto the function name, so you're concatenating a function with a string, instead of concatenating the result of calling the function.

template syl: {\an5\pos($scenter, $smiddle)}{!turn()!}

template syl: {\an5\pos($scenter, $smiddle)}{!turn()!}

It's still not working, i think is has some error in do and return?

[jfs]

Oh, I didn't notice you were abusing the function name that much.
Actually you probably won't need a callable function at all and can just do it directly in a code line... of course that will need to be a "code syl" line if you want it to update for every syllable.

Note that you're using the same name, "turn", for two different things. You're using it as the name of the function, but you're also using it for the name of the value the function calculates. Because the function is the first thing defined, it's the first thing that goes into the global variable by the name "turn" (in Lua, functions don't really have a name, their names are just variables that point to the function code) and after the function name has become valid, you start trying to treat the function value as a string.

Can you give me a example? I don't really get whats you say

I dont sure about the return command

function turn() for r=1,line.kara.n do b_turn = turn .. string.format("\\t(%d,%d,\\frz%d\\fry%d)",wind_off set*(r-1),wind_offset*r,rotz,rotz*3+10) if rotz < 0 then rotz = 0 else rotz = -math.random(1,3)*3 end end return b_turn end;

[jfs]

code syl: turntags = ""; for T = 1, line.kara.n do turntags = turntags .. string.format("\\t(%d,%d,\\frz%d\\fry%d)", wind_offset*(T-1), wind_offset*T, rotz, rotz*3+10); rotz = math.max(0, -math.random(1, 3)*3); end
template syl: {\an5\pos($scenter, $smiddle)}{!turntags!}

The code neatly formatted:

turntags = ""
for T = 1, line.kara.n do
    turntags = turntags .. string.format(
        "\\t(%d,%d,\\frz%d\\fry%d)",
        wind_offset*(T-1), wind_offset*T,
        rotz, rotz*3+10)
    rotz = math.max(0, -math.random(1, 3)*3)
end

The code will simply run once per syllable, before the template is processed, and build the "turntags" variable (resetting it to blank first). The value of that variable is then included in the template text.
Though, I'm not sure why the number of syllables in the line should determine how much the shaking/rotating is done, and why the timings of the syllables isn't used either when you're essentially doing the same thing for each syllable.
Another thing, this will obviously make each syllable get a different sequence of rotations, since the "turntags" is calculated once for every syllable, but you can easily change that to be once per line instead.

When I use code syl and wind_offset = syl.duration, the rotation of all characters are not synchronic, so I must to change to code line, wind_offset = line.duration/line.kara.n

Thanks you so much, this code'll help me for a lot of other karaoke FX

hello jfs can you explain mathrandom and to take me a sample exemple please

Returns the largest integer smaller than or equal to x.

math.fmod (x, y)

Returns the remainder of the division of x by y that rounds the quotient towards zero.

math.frexp (x)

Returns m and e such that x = m2e, e is an integer and the absolute value of m is in the range [0.5, 1) (or zero when x is zero).

math.huge

The value HUGE_VAL, a value larger than or equal to any other numerical value.

math.ldexp (m, e)

Returns m2e (e should be an integer).

math.rad (x)

Returns the angle x (given in degrees) in radians.

math.random ([m [, n]])

This function is an interface to the simple pseudo-random generator function rand provided by ANSI C. (No guarantees can be given for its statistical properties.)

When called without arguments, returns a uniform pseudo-random real number in the range [0,1). When called with an integer number m, math.random returns a uniform pseudo-random integer in the range [1, m]. When called with two integer numbers m and n, math.random returns a uniform pseudo-random integer in the range [m, n].

Sorry i wrong, I dont know how to call this.

code once: code_a = {"a", "b", "c"}
!code_a[math.random(3)]!

And i have a other question, how to set fx group for some syllables in once line, something like this,

fxgroup.ginkgo = (line.actor == "ginkgo" and syl.i == 1); fxgroup.ginkgo = (line.actor == "ginkgo" and syl.i == 5); fxgroup.ginkgo = (line.actor == "ginkgo" and syl.i == 9);
