一个令商品价格改变的脚本，加入事件里：
变量操作：[001]=$"价格变动脚本" #“价格变动脚本”= "x" 是给予100~300不同比率令商店操作价格全部变动的脚本
变量操作：[001]=随机数(100..300)
商店处理：[恢复剂]
以上操作无效果，是否变量不能这样操作
而同样是事件操作：
脚本：$"价格变动脚本" = 300
商店处理：[恢复剂]
这样就成功了令商品以%300价格买卖，为何之前错误？小白求点化

错了错了，LZ你错了喵~

应该是这样：
[001]=随机数(100..300)
脚本：$"价格变动脚本" = $game_variables[1]

理解，谢谢

不过出错了， “$game_system.tax.percent ”这是我脚本， $game_system.tax.percent = 120 为 120%价格

#============================================================================
# Shop Taxes V1.6 (VXA version)
# By Emerald
#----------------------------------------------------------------------------
# Originally made by Falcon for RMXP
# Edited by Emerald to fit the RMVX and now also RMVX Ace
# You're free to use the script for any game, as long as you give credits
#----------------------------------------------------------------------------
# Version History
# 0.5 -> Script ported to RMVX Ace with minor edits to avoid errors
# 1.0 -> Further edits due to problems with percentage taxes
#             Added possibility to easily configure x/y position of tax information
#             and a value to configure if it will even be shown at all.
# 1.5 -> Again, further edits due to slight problems. But aside from that,
#             you can use <tax key item> again. Also added possibility to create
#             items which alter taxes. DRASTICALLY changed Instructions, be sure to
#             read it thoroughly.
# 1.6 -> Added Sell taxes and item Sell Tax changes.
#----------------------------------------------------------------------------
# With this script, you can almost fully control prices for VX Ace. You can
# normally set prices and prices unique per shop, and this script adds the
# possibility to make taxes. With these taxes, you can easily change prices of
# all items in a shop, either higher or lower.
#
# Instructions:
#
# Just as always, put this script between ▼ Materials and ▼ Main. If the
# information about the taxes is not shown correctly in shops, you can change
# it below.
# 就像往常一样，把这个脚本▼材料和▼之间。如果信息无法正确显示在商店的税收，你可以改变它下面
#
# In order to add taxes, use the call script method within an event. Use
# the following codes codes:
#
# $game_system.tax.percent = x
# Where x > 100 results in a tax with x% the normal price
# 其中，x> 100结果在一个纳税X％的正常价格
# Where x < 100 results in a discount with x% the normal price
# 其中，x<100 X％的正常价格折扣
#
# $game_systeme.tax.direct = y
# Where y > 0 results in a tax which adds y to every price
# 其中y> 0，y为每一个价格在一个纳税
# Where y < 0 results in a discount which subtracts y to every price
# 式中，y<0的结果中减去y为每一个价格的折扣
#
# WARNING
# For n = the price of an item,
# If n - y equals 0, the item becomes free
# If n - y < 0, the item becomes free AND you GET money (why doesn't that happen
# in real life)
# If x = a negative value then you'll GET money (x% the normal price)
# 对于n =一个项目的价格，
#  如果n -  y等于0时，该项目成为自由
#  如果n -  Y <0时，该项目成为自由，你会得到钱（为什么不发生在现实生活中）
# 如果x =负值，那么你会得到钱（X％的正常价格）
#
#
# ALWAYS!!, unless you're SURE the player can't have any items which alter taxes,
# add $game_system.tax.perbon to percentage taxes and $game_system.tax.dirbon to
# direct taxes. Else, the changes of the items ARE NOT APLIED!!
# ALWAYS！，除非你确定玩家可以没有任何改变税收的项目，
# $ game_system.tax.perbon的百分比税和$ game_system.tax.dirbon到
# 直接税。否则，不APLIED项目的变化！
# END WARNING
#
# $game_system.selltax.percent = x
# $game_system.selltax.direct = y
# $game_system.selltax.perbon = x
# $game_system.selltax.dirbon = y
#
# Exact same story as above, only these are hidden and for items being sold.
# 精确上述同样的故事，这些都是隐藏的，正在出售的物品。
#
# <tax key item>
# Use the above tag if you don't want that the price of that item can be changed
# by taxes. Useful for items which the player may not buy/sell. 使用上面的标签，
# 如果你不希望这样的价格，该项目可以改变税收。有用的物品，玩家可以不买/卖。
#
#
# <tax +/-x>
# Use the above tag to make items which will alter direct taxes. Use + to make
# it higher, - to make it lower. Enter a value for x. 使用上面的标签，这将改变
# 直接税。高，使用+ - ，使其低。输入x的值。
#
# <tax +/-x%>
# Use the above tag to make items whcih will alter percentage taxes. Use + to
# make it higher, - to make it lower. WARNING!! The value you enter for x will
# be ADDED or SUBSTRACTED of the current tax.percent!! 使用上面的标记，让项目的
# 酦将改变比例税。高，使用+ - ，使其低。警告！您输入的x的值将被添加或中减去目前
# 的tax.percent！！
#
# Examples:
# $game_system.tax.percent = 150 & an item with <tax +20%> will result in a tax
# of 170%. “150”项目与<tax+20%>将导致在一个纳税170％。
#
# $game_system.tax.percent = 100 (/no value set) & an item with <tax -42%> will
# result in a tax of 58%.“100”（/没有价值的）一个项目，<tax-42%>导致58％的税。
#
# NOTE that if the player gets any items with these tags, the amount he/she has
# of the item determines how many times the taxes will be altered! Two of the
# same items in Example 1 will result in a tax of 190% instead of 170%.
# Also, if the player gets any items with these tags, the changes to taxes will
# be stored in $game_system.tax.perbon and $game_system.tax.dirbon for
# percentage and direct taxes respectively. Always add these variable to
# $game_system.tax.percent and $game_system.tax.direct respectively if changes
# to these two are made. Don't change perbon and dirbon as they only handle the
# changes made by items. 需要注意的是，如果玩家获得这些标签的任何项目，该项目确定
# 他/她有多少次税将改变！例1在同一项目中的两个将导致190％，而不是170％的税。
# 此外，如果玩家获得这些标签的任何项目的税收，将，在$ game_system.tax.perbon美元和
# 百分比game_system.tax.dirbon和直接税分别存放。一定要添加这些变量$ game_system.
# tax.percent的美元和game_system.tax.direct如果这两个分别。，不要改变perbon和dirbon，
# 因为他们处理的项目所做的更改。
#
# <selltax +/-x>
# Exact same effect as <tax...> but this one changes the prices of sold items.
# 精确相同的效果<tax...>但这个变化的价格出售项目。
#
# <selltax +/-x%>
# Same story as above.上同
#
# Use $game_system.selltax.perbon and $game_system.selltax.perbon for the above
# two tags.

错了错了，LZ你错了喵~
应该是这样：
[001]=随机数(100..300)

谢谢你的帮忙，

我的事件写法是:
变量操作:[0001:某某] = 随机数( 50..120 )
脚本:$game_system.tax.percent = $game_variables[1]
商店处理:某某......

而后当主角与事件角色一对话就出错
342行:NoMethodError
undefined method `>' for #<Game_Variables:0x76e004 @data=[nil,nil,105]

当前出错在此脚本“ if $game_system.tax.percent > 100 ”

xixifilm 发表于 2013-2-20 17:30
理解，谢谢

不过出错了， “$game_system.tax.percent ”这是我脚本， $game_system.tax.percent = 120 ...

是我脚本内

#============================================================================
#
# Window_ShopStatus
# Handles information of taxes shown in shops.在商店的税收处理信息。
#============================================================================

以下
“ if $game_system.tax.percent > 100 ” 出错

xixifilm · 发表于 2013-2-20 20:12:11

那个看似只是显示问题，
我取消了信息显示
# CONFIGURATIONS下
class Window_ShopStatus < Window_Base
TAX_INFORMATION = false 取消显示
就会发生:
227行：发生 TypeError
Game_Variables can't be coerced into Fixnum

感谢~!

我找到我自己的一个问题，不知道是否bug:

不是我的游戏版本问题，你的脚本也无错，我也照你的脚本写了，
问题是执行脚本事件时，由于$某某某=某某某[x] 这行太长了，超出了执行脚本的填写框，导致换行了，所以脚本出错

真是太感谢了，我现在商店终于可以随机价格

xixifilm · 发表于 2013-2-21 21:12:44

protosssonny 发表于 2013-2-20 21:03

对了，有没有留意，比率并没有把卖出价格计算在内，请问能帮手看看脚本，是另外有指令，或者要怎么写?
