Nate wrote Are the differences in accuracy meaningful? I would expect that not to matter most of the time, though I don't remember exactly how 3.5 behaves.
Since our characters can emit projectile from spine' bone,the accuracy may cause projectile hit target early or late one or two frame,It's do meaningful for our games.
I finally decide to use GUI to output all .spine projects,by using script record mouse operation and replay it :lol:
Thanks a lot!
