I mentioned in earlier posts that I am teaching myself how to program so I can play this game.
I taught myself basic on a TI82 more than 10 years ago, well enough to make a little game for myself, so I know how to use booleans, logic and math. I don't feel like I am a lost cause. I do feel like I hit a wall though, in that things are getting complex enough that I can't wrap my mind around it all at once. The whole point of Object Oriented is to make things simple by encapsulating. I understand that, but I am having trouble putting that into practice.
I am hoping that someone will volunteer to help me. I would share a bot I have that is about 225 lines, and they would point out how I could break it down into seperate classes and assign them appropiately. It is functionally similar to the Herd example, with a bit more complexity in grouping up. I'd be in for alternative lessons, but the only context in which I have used programming is this game. I've read the Sun tutorials, but they just aren't sticking.
Struggling with learning concepts.
My thought is have one class for "master" behavior, one for "servant", and this as the default. I can pick out what code belongs to which, but I can't figure out how to make each bot into one or the other.

}The easiest way to do this is probably...
Code: Select all

return myClass.think(etc);
} else {

} else {

}
}
}
// And make these classes
//class Commander extends MasterAndServant { }
//class Servant extends MasterAndServant { }
