lua player 脚本实战！！npc自动行走函数

以下是npc自动行走函数(局部): 问题:多个npc时运行速度会很慢,请求指教:

核心原理:

当move==2时(NPC范围移动):

用随机取数,让npc自动选择运动方向,之后让npc按每步smallstep长度走长为steplong的一段距离,

然后休息长为stoptime的一段时间,休息完后重复以上动作......

变量说明:

pstop:主角运动情况(1值为不动,0值为动)

npcn:npc总数

npc[i]:第i个npc数组

具体:

npc[i]=

{

stop=(0值为npc不动,1值为npc动)

linekg=(npc路线开关,无视它)

direction=(npc运动方向:1,下移;2,左移;3,右移;4,上移)

p=(地图上现示的npc图片)

right1,right2,right3,left1,left2,left3,up1,up2,up3,down1,down2,down3=(地图上现示的每个方向的npc 3张图片,以达动态效果)

movemanwallkg=(npc路线挡路开关,无视它)

move=(NPC运动模式 0:NPC不动,1:NPC只动双脚,2:NPC范围移动)

tt=(NPC停止时的等待时间)

stoptime=(NPC停止时间1000=1秒)

count=(NPC时间计时器)

ran=(随机取数,让npc自动选择运动方向)

x,y=(NPC在地图上的坐标)

smallstep=(NPC移动速度)

steplong=(NPC一次运动的长度)

stepnow=(NPC已经运动的长度)

walktime=(借助主循环npc 3张图片变换计时器)

time1,time2,time3=(借助主循环npc 3张图片变换频率)

}
