判定点
判定点是用来确定是否中弹的设定。在弹幕游戏中,它比角色图像要小很多,所以玩家可以让子弹从角色身上的大部分区域穿过而不必担心中弹。
游戏
子弹有各自的判定,普遍的规则是大的子弹有小的判定,小的子弹有大的判定(或者说,大的子弹,安全区也大)。另外,头目的判定区一般比显示的更大,允许玩家更容易地攻击。
角色判定点
在东方系列游戏中,角色的判定点是一个小圆在腰部附近。在东方妖妖梦及之后的游戏中,按住低速键就能看见判定点。
Delving further into specifics, the general size of a Touhou character's hitbox is around 5 pixels in diameter (the actual shape seems to be a rotating square with rounded corners). Starting in Perfect Cherry Blossom, Reimu traditionally has a smaller hitbox, measuring about 4 pixels in diameter.
Even without going into focused mode, however, it is generally possible (and quite easy once you get the hang of it) to give a decent approximation of a hit box's size and location by taking a look at the characters; usually, a small design on their clothing around the character's waist usually can point out where it is.
Additionally, a snowflake or spell circle will also surround the character. These represent the graze hitbox and the item collection hitbox, respectively.
