Any progress?

Great result ! Any plan to merge it?

呃对，这样改动是最小的。 其实我直接在start里面x2 = x1; y2 = y1了。暂时我只用到单指，多指逻辑还没考虑。 我是想问把start作为move的上一次事件有什么问题吗？觉得这样更顺一点。还不用null判断。 另外看到 https://github.com/AlloyTeam/AlloyFinger/blob/4a34955d672dd1f3477b8ccaa60dfe5bec2e35db/alloy_finger.js#L163 这个在end时候置0，实际也只有第一次跳过null了，null判断也比较多余。 https://github.com/AlloyTeam/AlloyFinger/blob/4a34955d672dd1f3477b8ccaa60dfe5bec2e35db/alloy_finger.js#L257 所以想问，把start作为move上次事件写是不是更好？或者多指有什么考虑？
