Hi.


i have just made my first AI EVER!!

But it is still really good(i think).

*Controls* :

Control the green box using:

Upkey = move forward
downkey = move backwards
leftkey = move left
rightkey = move right

And then a red box will follow you!


If you wanna try it then here is the code:
(compressed version) :



Here is the version with comments:




Hope you all like it

I hate to tell you that this can be done in about 10 lines...



I wouldn't really count this as AI either. Anyway, it is definately a useful technique for getting one object to follow another.

Good point for discussion, though - what is AI and what isn't? I would have said this isn't AI, because I think AI means it has to have the appearance of some form of intelligence. And something that follows something else (like for example a caravan on the back of a car) doesn't to me display 'intelligence' - it is merely a physical process.

If you could get it to follow you whilst avoiding obstacles - then that would be AI in my book, because it would have the appearance of making decisions - ie which is the best way around the obstacle.

AI is basically anything where the computer reacts intelligently to an event. Now the question is "Define intellegence". In the context, The Nerd's code is very much AI. As it turns out, the computer doesn't have to react that intellegentally (see I can't spell, but I'm intelligent!) to be considered AI. Btw The Nerd, coming from a background of QBASIC, that code would have been a LOT harder to have accomplished. So be happy that the world is more simple now and AI is easier to obtain .

The following object is not attached to the player object so it is not just a physical motion. Therefore, the computer is working out where the player is and making the other object follow it; AI.

Ric, your right. AI is more like that object(characters) can think and make decissions.

If you give a character the command to follow (in-game) then the character needs to make a decission to follow you or not. Or in a deathmatch game, the bots needs to decide wich other player/bot they want to attack.

Thats real AI.

Even better is, that your program can learn from itself. I'm trying that too, its a bit hard though.

I agree with Ric, if the Nerd can make it dodge obsticles (can't spell) or work out the quickest route to the object then I'll be more impressed (seeming as I don't know how to do that )

Point taken, although I don't think AI is anything to do with how the computer is working something out - it's only to do with how it's behaviour appears on the surface. We all know that under the surface, there is no intelligence there. But if it appears to a human observer that it is behaving in an intelligent way, then it has AI (The same sort of principle as the Turing test for intelligence).

In this case, it appears to be a physical process, as it follows the other object no matter what. If this is AI, then so would a train be said to possess AI, as it follows the direction of the track. The way they work is different, but on the surface, the two things are the same to an observer

p.s. I watched IRobot, so I'm an expert.

@Ric: lol.Nice. Ghosts in the code.

@nerd: Hey I see that your learning well. Keep it up.

For obstacle avoidance and stuff check out IanM's A* routines and my version that I ported to make it DBC compatable
