text: I am making something to automatically cast spells at enemies on League of Legends.
  
  I am able to get the 100% precise interpolated position of the enemy where he'll get hit by my spell, if he stays on his path, and if i cast my spell towards this position.
  
  In order to not waste my spell i want to create a hitchance system.
  
  Enemy hitbox are a circle and have a radius always lower than my spell hitbox.
  My spell hitbox can be either a rectangle or a circle.
  This information can be used to get the time the enemy has to be able to dodge my skillshot, once he notices that it's coming towards him.
  
  I have informations about enemy current and old paths. A path is an array of vector2d, those vector2d are basically just waypoint that the enemy will follow.
  The hitchance system should be a system that tell me how likely the enemy is gonna stay on this current path.
  This shouldn't use artificial intelligence or machine learning.
  The start position of my spell cannot change, it is fixed.
