Ifcansee
If condition returning true if there is a line of sight between the current actor and the player.
The difference with ifcanseetarget is that ifcansee actually verify if the player can see any actual part of the current actor tile (and basically would be hard to the player say how an enemy looked alike while standing except if he use F7 view mode), while ifcanseetarget verify if the current actor has "eye contact" with the player (and in result the player is capable of viewing a arm or a litoral part of an enemy without it targeting the player).
