AutoTags 原始函数代码

function AutoTags(Intervalo,Dato1,Dato2) --Intervalo为时间间隔，Dato1/2为变化的内容
    local RESULTADO=""  --初始化 RESULTADO为输出结果
    local SUERTE = 0 --初始化局部输出存储器
    local CONTADOR = 0 --初始化计数器
    local ARREGLO = 0 --初始化表，用于存储前后变换的两个标签
    local count = math.ceil(line.duration/Intervalo) --总的变换次数
    ARREGLO = {Dato1,Dato2} --把两个变换的状态写入ARREGLO表，方便奇偶调用
    for i = 1, count do --核心循环
        CONTADOR = i --重复计数器数值
        if Dato1 and Dato2 then --拒绝Data1和Data2为空时的无效变换？

            if  CONTADOR%2 ==0 then --从默认变成Data1，再变成Data2
                SUERTE = ARREGLO[1] --将标签写入临时的输出
            else
                SUERTE = ARREGLO[2]
            end

        end
        RESULTADO = RESULTADO .."\\t(" ..(i-1)*Intervalo.. "," ..i*Intervalo.. ",\\" ..SUERTE..")".."" --从0开始输出并叠加变换
    end
    return RESULTADO --返回最终结果
end

如上，在使用函数时，传入值的Dato1和Dato2应当为字符串，固用' '框起来。
函数返回值无{}，固应当在template行中写类似{AutoTags(Timeinterval,'fs50','fs20'}

因为是写在代码当中，所以如果要有多个变化同时发生，需要用\来写后续的特效标签。例如{AutoTags(Timeinterval,'fs50\\frz90','fs20\\frz0'}

变种[2]

AutoTags1 (with pause):停顿

可以让每个变换之间有时间间隔/停顿。

function AutoTags1(Intervalo,Dato1,Dato2,Pause)  local RESULTADO=""  local SUERTE = 0  local CONTADOR = 0  local ARREGLO = 0  local count = math.ceil(line.duration/(Intervalo+Pause))  ARREGLO = {Dato1,Dato2}  for i = 1, count do          CONTADOR = i          if Dato1 and Dato2 then                  if  CONTADOR%2 ==0 then                  SUERTE = ARREGLO[1]                  else                  SUERTE = ARREGLO[2]                  end          end          RESULTADO = RESULTADO .."\\t(" ..(i-1)*(Intervalo+Pause).. "," ..i*Intervalo+Pause*(i-1).. ",\\" ..SUERTE..")"..""  end  return RESULTADO  end

AutoTags2 (with Delay):延迟

可以让变换有不同的开始时间。可以配合$si等使用。

function AutoTags2(Intervalo,Dato1,Dato2,Delay)            local RESULTADO=""     local SUERTE = 0     local CONTADOR = 0      local ARREGLO = Layer                            local count = math.ceil(line.duration/Intervalo)                                         ARREGLO = {Dato1,Dato2}                                          for i = 1, count do               CONTADOR = i                                            if Dato1 and Dato2 then                                             if  CONTADOR%2 ==0 then                                                                    SUERTE = ARREGLO[1]                                            else                                                                    SUERTE = ARREGLO[2]                                            end                            end                                                 RESULTADO = RESULTADO .."\\t(" ..(i-1)*Intervalo+Delay.. "," ..i*Intervalo+Delay.. ",\\" ..SUERTE.. ")"..""                                  end                              return RESULTADO                                             end

AutoTags3 (Different Intervals):不同的时间间隔过渡

AutoTags3(第一次变化用时,最终变化用时,”标签1″,”标签2″)
即，每个\t变换的时间，会从Interval1逐渐过渡到Interval2

function AutoTags3(Intervalo1,Intervalo2,Dato1,Dato2)  local RESULTADO=""                 local SUERTE = 0                 local CONTADOR = 0                 local ARREGLO = 0                               local count = 2*math.ceil(line.duration/(Intervalo1+Intervalo2))            local d=math.ceil((Intervalo2-Intervalo1)/count)  local t={}  ARREGLO = {Dato1,Dato2}                                                      for i = 1, count do                                   CONTADOR = i  t[1]=0  t[i+1]=t[i]+Intervalo1+(i-1)*d  if Dato1 and Dato2 then            if  CONTADOR%2 ==0 then                                                                                        SUERTE = ARREGLO[1]            else                                                                                        SUERTE = ARREGLO[2]                                                        end            end                                                             RESULTADO = RESULTADO .."\\t(" ..t[i].. "," ..t[i+1].. ",\\" ..SUERTE..")"..""                                              end                                          return RESULTADO                                                         end

自用流水灯效果函数：colorTag

在制作「派对浪客诸葛孔明」的OP特效时，遇到了需要彩色流水灯效果的需求。

因为AutoTags（好像）不支持多个状态循环的变化，于是重写了一个用于生成循环变色效果的代码。

colors = {"&H003202C7", "&H0015CCD7", "&H0092321E", "&H0004C026", "&H0096C121", 
    "&H009C8CCC", "&H00AB4EB8"
}
colorNum = 7 -- 总的颜色数，即colors表的元素数
function colorTag(sylNum, timeDuration, timeGap)
    currentStart = 0
    currentEnd = 0 + timeGap
    currentColorNum = sylNum % 7 + 1 -- 当前选定的颜色
    colorResult = "" -- 输出结果
    colorResult = colorResult .. "\\3c"..colors[currentColorNum] -- 添加初状态
    while timeDuration - currentEnd > -timeGap do
        currentColorNum = (currentColorNum + 1) % 7 + 1
        colorResult = colorResult .. "\\t(" .. tostring(currentStart) .. "," .. tostring(currentEnd) ..",\\3c" .. colors[currentColorNum] .. ")"
        currentStart = currentStart + timeGap
        currentEnd = currentEnd + timeGap
    end
    return colorResult
end

colorTag(5, 2000, 120)
>>> \3c&H009C8CCC\t(0,120,\3c&H003202C7)\t(120,240,\3c&H0092321E)\t(240,360,\3c&H0096C121)\t(360,480,\3c&H00AB4EB8)\t(480,600,\3c&H0015CCD7)\t(600,720,\3c&H0004C026)\t(720,840,\3c&H009C8CCC)\t(840,960,\3c&H003202C7)\t(960,1080,\3c&H0092321E)\t(1080,1200,\3c&H0096C121)\t(1200,1320,\3c&H00AB4EB8)\t(1320,1440,\3c&H0015CCD7)\t(1440,1560,\3c&H0004C026)\t(1560,1680,\3c&H009C8CCC)\t(1680,1800,\3c&H003202C7)\t(1800,1920,\3c&H0092321E)\t(1920,2040,\3c&H0096C121)

函数说明：sylNum为当前音节的序数，配合计数器使用，用于产生颜色错位。timeDuration为当前行的时间长度。timeGap为渐变间隔时间。

应用举例（line）

如果希望结果只有一行显示（而不是每个syl各一行），只要把修饰语改为template line，并调整（删除）定位标签。
