Post Re: RCX TTT Player
How good is the code? Is it unbeatable but imperfect (i.e. it doesn't win every time it can) or is it still beatable?

Um yeah totally beatable. Plus there are several glitches such as: if you win it still keeps playing.

:) That's just like some of my friends! They are totally beatable AND they keep playing after I win!

Post Re: RCX TTT Player
I rewrote the code. I also got rid of the Arduino circuit in favor of an autovalve. Current code here:

Code:
#pragma config(Sensor, S1, LhtLmt, sensorReflection)
#pragma config(Sensor, S2, xPos, sensorTouch)
#pragma config(Sensor, S3, yPos, sensorTouch)
#pragma config(Motor, motorA, PneumSwch, tmotorNormal, openLoop)
#pragma config(Motor, motorB, xAxis, tmotorNormal, openLoop)
#pragma config(Motor, motorC, yAxis, tmotorNormal, openLoop)

It's some 200 lines shorter than my original code and performs better. I'm testing it as the human player in a supposedly unbeatable TTT program I found. :lol:

Post Re: RCX TTT Player
Just a question: Have you considered rewriting the board as a 2-dimensional array? Of course with the right code 1-D's are just as good as 2-D's.

Post Re: RCX TTT Player
RCX no support 2D array. :(

That's why I have a 9-cell array and address it like so:
Code:
Board[x + y * 3] = 1;

Ends up working just like a 2D array, with just that little bit of extra maths when addressing it.

Post Re: RCX TTT Player
Yeah. I once wrote the bones of a maze solving robot w/ a 1D array, then realized that robotc supported 2D's, so I rewrote all 800+ lines...... tiring.

Post Re: RCX TTT Player
Yeah... :|

800+ for a maze solving robot sounds a bit excessive though. I did one that solved a physical maze, like it actually followed the lines that the maze was made out of, and it was less than 400 lines including victory music. :P

Post Re: RCX TTT Player
Well actually, over half was the extremely user-friendly interface. That might be why it was long. You could select start, finish, mode(there, there & back, or find exit), direction robot originally faces, and save or erase the known data of the walls. It was nice.

Well there's your problem! :lol: Although mine didn't do a wall maze, it was a maze made out of tape on floor tiles.

So when you say it performs better, how much better? Can you still beat it?

Yeah I can still beat it. I improved it a bit today, but still trying to find the level of unbeatableness that I've seen in other things. It's less susceptible to forks now, but there are still a few bugs.

Post Re: RCX TTT Player
I found a seemingly unbeatable TTT strategy in an old book of mine. I'm gonna try to implement it and see if the performance improves. Work is gonna halt on this for a bit as I'm working on another flexpicker. :mrgreen:

Probably. Although that kinda defeats the purpose of doing it with just an RCX.
