Basically I wanted to add a function to look at a shape the player will draw with whatever means of input they are using and check it for accuracy with pre-defined shapes. I’m sure you’ve seen games like this. Stuff like Okami, or Magic Touch on droid.
Without giving too much away, cause I’m not asking for code, I’m just asking how does this get done. If this was asked before, please be patient with me, I didn’t see any question like that when I posted. 
Thanks for reading.

This link might help you. In the comments there is a scientific paper someone’d suggested but failed o implement it, however, it is very interesting. Otherwise if you want an out-of-the-box solution I highly suggest checking out the market place and the keywords “Glyph Recognition”
I am just about to buy this one because I am very lazy, might try implementing it myself though.
