说明：这是milk前辈从X大写的效果移植过来的，用了种子填充算法，正好应Alex的要求。
具体见脚本，就不解释了（我也还没看）。
用TCAS生成了，渲染效率高点。
附上工程，可以 prase 看看。附件去掉了片源和字体，体积太大就不放了。

如果有疑问，直接跟帖。

##### 基本函数库, 必须包含 #####
from tcaxPy import *
##### 额外的一些库 #####
from collections import deque
def RandomDouble_Gauss(l, h):
return RandomDouble_Gauss_(l, h, 6)
def RandomDouble_Gauss_(l, h, g):
sum = 0
for i in range(g):
sum += RandomDouble(l, h)
return sum / g
def RandomDouble(l, h):
return l + (h - l) * random()
##### 初始化函数, 用于设定一些全局变量 #####
def tcaxPy_Init():
##### 声明全局变量 #####
global _FontFileName # 字体文件名
global _FaceID # 字体Face序号
global _Fs # 字体大小
global _TextWidth # 文字宽度
global _TextHeight # 文字高度
global _TextLength
global _TextAdvDiff
global _ResolutionX
global _OffsetX
global _FD # 一帧的持续时间, 40毫秒
global Font # 首要字体
global FontOut # 字体边框
##### 获取预定义的值 #####
_FontFileName = GetVal(val_FontFileName)
_FaceID = GetVal(val_FaceID)
_Fs = GetVal(val_FontSize)
_TextHeight = GetVal(val_TextHeight)
_TextWidth = GetVal(val_TextWidth)
_TextLength = GetVal(val_TextLength)
_TextAdvDiff = GetVal(val_TextAdvanceDiff)
_ResolutionX = GetVal(val_ResolutionX)
_OffsetX = GetVal(val_OffsetX)
_FD = 1000 / GetVal(val_FXFPS)
##### 设置自定义变量的值 #####
Font = InitFont(_FontFileName, _FaceID, _Fs, GetVal(val_Spacing), GetVal(val_SpaceScale), 0xFFFFFF, 0, 0) # 0xFFFFFF为16进制表示的白色
FontOut = InitFont(_FontFileName, _FaceID, _Fs, GetVal(val_Spacing), GetVal(val_SpaceScale), 0xFFFFFF, 4, 1) # 最后一个参数置为1表示只提取边框
##### 结束函数, 用于一些收尾工作 #####
def tcaxPy_Fin():
##### 清理一些全局变量 #####
FinFont(Font)
FinFont(FontOut)
##### 脚本主函数, 会对每个文字执行一次 #####
# _i 第_i句, 即当前操作的文字所在的句子序号
# _j 第_i句中的第_j个文字, 即当前操作文字的序号
# _n 第_i句中有_n个文字, 即当前句子所包含的文字数
# _start 句子的开始时间
# _end 句子的结束时间
# _elapk 到第_j个字经过的时间, _start + _elapk 到 _start + _elapk + _k 即为当前文字的存在时间
# _k 第_j个文字的卡拉OK时间
# _x 第_j个文字的水平坐标
# _y 第_j个文字的垂直坐标
# _a 第_j个文字的水平跨距, 可以看作文字的宽度, 同样_Fs也可近似看成文字的高度
# _txt 第_j个文字的内容
