Option 1 : Book1 This book is made by the author of the tutorials I did and I think is good but might not be advanced enought.
Option 2 : Book2 Its an advanced book but not sure if its good since it could be too advanced for me
Option 3 : Book3 It seems good enough.
There is more books for Unity scripting languages but these 3 I think are the best. Please tell me which one you think is the best and link me to some other one if you think its better than any of these.
