Author Topic: GridWars game - going to add AI to it. (Read 4178 times)

Dav · « **Reply #15 on:** November 03, 2021, 09:17:56 pm »

I haven't been able to work on this as much as I would like, but I have done something new with it and would like some testing on this version please.

This new version auto-scales the puzzle board based on your current desktop size. Hopefully the puzzle will now look and play the same regardless of your screen size. (That means it won't look like an icon on Steves super duper laptop!)

Instead or hard-coding the pixel size with everything, all the graphics are scaled based on _DESKTOPHEIGHT now, the font is too. The only thing I have found is that on large screens (over 2000 desktopheight) the game plays sluggish.

After doing all this changing, it then hit me that I really should have tried to add @SMcNeill autoscale thing first. Anyway, I've tried this in 4 different screen sizes and the puzzle fills the screen pretty nicely. How does it display on yours?

'Coded by Dav NOV/2021
 
'NEW FOR v0.4:
'  * Board auto sizes based on users desktop settings.
'    Game should look and play same on any screen size now.
'  * Randomized AI so game doesn't always start playing same way.
'    (AI scans board from top OR bottom now - not always from top)
'  * Random player starts - not always human goes first now.
 
'TO DO: Make if player doesn't have a move, but other player does,
'       auto-fill in rest of board with the movable players color.

Your AI plays "too good!", it makes a move and suddenly half my pieces are it's color. I go,"What?!" If it made a jump, I swear the place it jumps from is not leaving a hole that it occupied, maybe not?

Is it possible to highlight the last move AI made with it's piece, from and to? I don't want to accuse it of cheating simply because it doesn't care! (My tendency would be just to quit playing with it.)

PLUS for extra bonus, when showing legal moves show by color difference which are jumps that should leave hole and which are "clones" (good name, and maybe something I am not use to playing with/against).

How does it display on yours?

Pretty much the same as before which was already fine.

@Dav ...

Game looks great! Played 2 games, won both, the second one by a large margin. I am not going to dive into the AI at this time, you must have something going on - it appears that the AI looks for the move with the biggest piece turnover, and takes it, without considering position, especially along the sides.

A couple of things I noticed...

When the game ends and the winner is announced, the score is not updated, the game just moves on to the next game.

Also, sometimes there is a big delay between selecting a piece with the mouse, and the piece becoming "active" and ready to move.

But your game is coming along nicely! Like the sound effects!

@bplus: Hmm, I haven't caught it cheating yet, but perhaps I made a mistake in the change sub, an it's flipping squares wrong somewhere. I will double check that. Maybe I can add a tracer to see what happened at last move. Was thinking of adding a UNDO last move thing. I may add difficulty levels, easy, medium, hard. Where it is now would be the hard one. Thanks for telling me how it displays on your system!

@Statsman1. Thanks! You have a keen eye. You are correct, the AI takes the move that gives it the most gain for that move. I need to do a look ahead - see if the next best for the human would result in less pieces after all, or something. Thanks for catching the score not being updated at the end. I hadn't noticed it. About the delay, yeah it happens to me when the window is larger than 1400 pixels high, I'm not sure how to fix that but will investigate. Thanks for trying it out!
