So I think you could help me
.Thing is: I want to make a game with Ants and because I love these Animals and they seem to be perfect to implement to a Game, because ( until now ) there are only 20 known Operations they can do and they are quiet easy to implement ( I had c++ at the university, but only console-applications ).
Problem:
Ants leave a smell while looking for meal or something ( 20 operations ). I wanted to implement that by leaving parts of the PlayBoard behind the Ants "shine". But if they overlap the Shine is brighter ( hard to explain with words but really simple ).
I had two Ideas:
1: I define squares over the whole Playboard, so I can define the Strenght of smell by an intended Value, or
2: I use the defined Line-Method and calculate by distance.
I want the Program to work mostly efficient, and depending on the Size of the PlayBoard both seem to have their Advantage.
What would you prefer or do you have a better Idea of making it?
Whatever... Thanks Dude
p.s.: Why don't you include "string" or something from the "stl"? I know you are going Step by Step, but if you dont include them because of any Problems ( like Runtime ) I just have to know
.
), for that you'd need a line drawing function that takes that into account
