一个技能关于数学的问题

frozenleave

我做了个技能，其中伤害部分的触发注册是这样的注册事件是单位接近指定单位80范围，条件无，动作伤害触发单位。指定单位呢，我用timerstart把她沿一条直线运动，是每0.01秒时间，每次移动距离为50，技能设定是点目标或单位目标，而当我用这个技能点一个敌方单位时，却有一定的概率会伤害不到，而根据数学，目标单位在那条直线上，而每次移动距离50是小于触发事件中的范围直径160，就是所目标单位一定会进入这个范围，所以这个伤害的触发理应可以触发，但为什么却有一定的概率不触发呢？而当我把范围调成300的时候，伤害就是100%了，从不丢失，对于这一点我十分的迷惑，哪位高人出来指点一下迷津？
