鼠标点住了图片，打开了某个窗口退出来时，人物竟然行走到图片的位置那了。能不能让鼠标点击图片的时候不让人物动？

这个是鼠标

#==============================================================================
# ■ 完整鼠标系统(四方向)
#------------------------------------------------------------------------------
# 　使用时务必配合专用寻路算法
# By whbm
#==============================================================================
#下面做一下介绍与使用说明：
# 在屏幕上单击鼠标的时候，会自动进行寻路，这里为了速度更快并且为了进行迷
#宫时的难度寻路被限定在当时的屏幕内部。（否则玩家直接点到终点，呵呵....知道
#后果了吧）
# 在角色移动过程中再次单击鼠标（即双击）并在单击第二次鼠标的时候不松手，
#角色将会跟随鼠标方向移动。（这个应该好理解，不用多说吧）当角色贴着欲被启动
#的事件的时候，单击NPC即可启动事件。若未贴着，将会产生自动寻路到NPC附近的某
#点，那时在单击NPC即可。
# 当鼠标停在某些事件上时候会发现有不同的图标，设置方法为：宝箱事件请在事
#件的执行内容中添加注释，注释内容为 Item 注意大小写。NPC事件请在事件的执行
#内容中添加注释注释内容为 NPC 注意大小写。若不箱改变某事件的图标，则不要写
#那两个注释。
# 当把脚本转到您工程的时候千万别忘了那个寻路用的脚本。
