[传奇技术]mir2res人物或怪物移动
mir2res优秀的地方之一:精灵移动
尽管有很多人说它是拉几,但我从来都相信mir2从coderes到picres都是一个优秀的游戏,超越同类mmrpg很多,下面谈谈它的一个方面
:精灵移动
因为对这个的讨论涉及到地图格及地图单元,先在头脑中想象一下地图格,这里不打算讨论地图单元
这里仅讨论actor.pas中跟动作有关的函数,,验证它的优越之处,,
现在开始,,下面是从mir2res中提取的源程序片断,,正是它们构成了精灵移动的基础

if min(1,max())= 取max then，，max只能取0,,负数,,因此在max内部,,要么为0，不能是-1(为0时,此时x-mapx=-1,x=mapx-1),,要么为负(此时x-mapx<-1,,x<mapx-1)
也即x<=mapx-1
实际意义就是用户点了(这里只讨论x方向)人物当前x坐标前一个方向
if min(1,max())= 取1 then, , max内部只能取2,,或2以上(max不能是1),,因此x-mapx是,,即x>=mapx+2,,此时x在水平方向总是要比mapx大二个或二个地图格以上
即(实际意义):用户在水平向上点击了比mapx大二个或二个的地图格以上的地图位置，，此时movx被计算出来,为>=2
以上讨论水平方向，这里讨论垂直方向，二个方向共同作用，，确定movx,movy,,注意到在上面的过程中，min()只能取1,,或>=2的数值max(),,
下面讨论竖直方向的情况,同一个道理
MovY := Min(1, Max(-1, Y - MapY));
三种情况,,,1,,y=mapy 2,,y<mapy 3,,y>=mapy+2
设想一下,y仅仅>mapy,,而不规定y>=mapy+2时，比如y=mapy+1时也就是用户点击人物当前位置竖直方向再往下一个伴置，此时
y>mapy,,但y不>=mapy+2,（至少要3个地图格）,此时不满足上面三种情况的任何一种情况
if (MovX = 0) and (MovY = 0) then Exit; 用户点了站立的位置，，相当于不走，exit,,即walk()函数不发挥作用

if not CurrentMap.CanMove(MapX + MovX, MapY + MovY) then Exit; //如果地图不能走当然也就不能继续walk()了
CurrentAction := HUMANACTION_WALK;
