卡拉OK内联特效

卡拉OK inline-fx(内联特效)可以用来给打过k的时间轴的不同部分分配不同的特效。

inline-fx标记本身并不会有任何影响,只有当应用可以识别它的卡拉ok特效脚本时才会应用于打了k的轴。

标记

内联特效标签是一个(无效的)ASS特效标签,格式是\-特效名,其中 特效名 是内联特效所定义的。

和普通特效标签一样,内联特效标签同样只会影响其后的音节,直到下一个内联标签为止。

一行的开始会重设为无内联特效。

Example

这是一行带内联特效标签的卡拉OK字幕:

{\k40}zu{\k20}t{\k42}to {\k32\-paint}e{\k17}ga{\k45}i{\k32}te{\k26}ta {\k24\-cloud}yu{\k55}me

这些音节会被分配如下的内联特效:

Syllable Inline-fx
zu (blank)
t (blank)
to (blank)
e paint
ga paint
i paint
te paint
ta paint
yu cloud
me cloud

卡拉OK模版执行器中的用法

如果你用卡拉OK模版执行器来制作特效,你可以在模版上使用 fx 修饰语来指定其仅对特定的内联特效生效。这种方式无法(直接)匹配无内联特效标记的音节。

Example

接着之前的卡拉OK行的例子,你可以写出下面的模版:

template syl: {对所有音节生效的默认效果}
template syl fx paint: {仅对“paint”音节叠加生效的效果}
template syl fx cloud: {仅对“cloud”音节叠加生效的效果}

这里的想法是先有一个基本的效果,然后为某些音节设计更多的效果。

Example

通过使用一个基于内联特效而启用或禁用的 fxgroup,可以在卡拉OK模版执行器中匹配空白内联特效的音节。 您也可以使用多个 _fxgroup_来执行多个内联特效的模板。

code syl: fxgroup.blankfx = (syl.inline_fx == "")
template syl fxgroup blankfx: {仅对空内联特效音节叠加生效的效果}

重要的是,code行在每个音节都会执行,并且会在每个需要使用它的对音节生效的模版之前执行。

Lua脚本中的用法

The inline-fx tags are parsed by `karaskel.preproc_line_text` so they will only work if you have applied at least that much karaskel pre-processing on your subtitle lines.

The inline-fx for a syllable is then available as syl.inline_fx, which you can compare to a string to conditionally apply effects.

Example

In some code that runs per-syllable in your script:

if syl.inline_fx == "" then
    apply_base_effect(subs, meta, line, syl)
elseif syl.inline_fx == "paint" then
    apply_paint_effect(subs, meta, line, syl)
elseif syl.inline_fx == "cloud" then
    apply_cloud_effect(subs, meta, line, syl)
end

Simply compare the inline-fx name to the various possibilities and run the right effect code.

Example

In some code that runs per-syllable in your script: At top-level of your script:

effects = {}
effects[""] = function(subs, meta, line, syl)
    -- base effect code here
end
effects.paint = function(subs, meta, line, syl)
    -- paint effect code here
end
effects.cloud = function(subs, meta, line, syl)
    -- cloud effect code here
end

Then later, in some per-syllable processing code:

effects[syl.inline_fx](subs, meta, line, syl)

First, a table is created and filled with functions for applying the different effects. The keys used for the table are the names of the possible inline-fx. When the effect has to be applied, the right function is looked up in the effect table and then called.
