尝试对本地变量'g2'（一个函数值）进行索引。

我使用的程序叫做 Oxidizer，是一款 fractal flam3 编辑器。基本上，为了制作这些美丽的数字艺术作品，我使用了 .lua 脚本。

我正在使用的一个脚本叫做 algorhythm.lua，它调用其他脚本以使之正常运行。其中一个脚本是控制脚本 cs_temp.lua，另一个是 utils.lua。而我收到错误的地方是在 utils.lua 的第 1399 行，也就是下面代码的第二行。

function alignx(g1,g2)
   local x1,x2 = #g1.xforms,#g2.xforms
 -- Align xforms for final-x, pad if necessary
local fx1,fx2 = 0,0

for x=1,x1 do
      if g1.xforms[x].is_finalxform == "Y" then fx1 = x end
   end
   for x=1,x2 do
      if g2.xforms[x].is_finalxform == "Y" then fx2 = x end
   end
   if fx1>0 or fx2>0 then

  -- case 1: both have finalx - reorder g2

  if fx1>0 and fx2>0 and fx1~=fx2 then
 print('case 1')
 if fx1>x2 then              -- pad g2 with sufficient xforms
    for i=1,math.abs(fx1-x2) do
       table.insert(g2.xforms,newx())
       print("adding xform to genome 2")
    end
    x2 = #g2.xforms
 end
 x2ind = agen(x2,1,x2)
 x2ind[fx2] = fx1
 x2ind[fx1] = fx2
 xforms2 = ordx(g2.xforms,x2ind)
 g2.xforms = xforms2
  end

  -- case 2: g1 has finalx but not g2 - xpad and reorder g2
  if fx1>0 and fx2==0 then
 print('case 2')             -- pad g2 with final xform
 local xtmp = newx(1)
 xtmp.is_finalxform = 'Y'
 xtmp.symmetry = 1
 table.insert(g2.xforms,clone_genome(xtmp))
 print("adding final xform to genome 2")
 x2 = #g2.xforms
 fx2 = x2
 if fx1>x2 then              -- pad g2 with sufficient xforms
    for i=1,math.abs(fx1-x2) do
       table.insert(g2.xforms,newx())
       print("adding xform to genome 2")
    end
    x2 = #g2.xforms
 end
 x2ind = agen(x2,1,x2)
 x2ind[fx2] = fx1
 x2ind[fx1] = fx2
 xforms2 = ordx(g2.xforms,x2ind)
 g2.xforms = xforms2
  end

  -- case 3: g2 has finalx but not g1 - xpad g1 and reorder g2
  if fx1==0 and fx2>0 then
 print('case 3')
 local xtmp = newx(1)
 xtmp.is_finalxform = 'Y'
 xtmp.symmetry = 1
 table.insert(g1.xforms,clone_genome(xtmp))
 print("adding final xform to genome 1")
 x1 = #g1.xforms
 fx1 = x1
 if fx1>x2 then              -- pad g2 with sufficient xforms
    for i=1,math.abs(fx1-x2) do
       table.insert(g2.xforms,newx())
       print("adding xform to genome 2")
    end
    x2 = #g2.xforms
 end
 x2ind = agen(x2,1,x2)
 x2ind[fx2] = fx1
 x2ind[fx1] = fx2
 xforms2 = ordx(g2.xforms,x2ind)
 g2.xforms = xforms2
  end
 end
end

我知道这很多，但我尽可能具体。
