这个脚本为什么不能随机更改战斗背景图 - Project1

#==============================================================================
# 随机渐变,区域控制战斗背景图 by 沉影不器
#------------------------------------------------------------------------------
# 功能描述: ① 使用区域名称定义不同的战斗背景图
# 如果没有找到背景图,则使用RMVX默认眩晕背景
# ② 进入战斗时,随机使用渐变效果
# 使用方法: ① 复制脚本,插入到Main之前
# ② 在Graphics文件夹下新建Battlebacks文件夹用于存放战斗背景图
# 您也可以在脚本第16行自行设定路径
# ③ 准备与区域名称相同的战斗背景图到您设定的战斗背景图文件夹内
# ④ 在Graphics文件夹下新建Transitions文件夹用于存放渐变图
# 您也可以在脚本第17行自行设定路径
# ⑤ 在脚本第18行设定战斗背景图的后缀名
# ⑥ 在脚本第19行设定是否直接用地图做战斗图
#------------------------------------------------------------------------------
B_PATH = "" # 设定战斗背景图存储路径
T_PATH = "" # 设定渐变图存储路径
EXTNAME = ".jpg" # 设定战斗背景图后缀名
DIRECT_MAP = false # 设定是否直接用地图做战斗图
