One thing you might add is that when you are in the hiding spot and think you are safe, a switch to scatter mode can get you eaten. Clyde can get you if he reverses while in his vertical loop by coming across where the fruit appears. Inky can get you if he loops around the lower right energizer area. This has happened to me when I've left a game to go do something else and it waits long enough for the 4th scatter. Great video! Usually, though, if I have Clyde in his horizontal loop, I make it through fine--probably because the 4th scatter is too short for Inky to do anything harmful.

Its not to complication, the ghosts don't see cordores, it sees collision. it will update its target, then check for tiles that count for collision around it as per normal (down and left is blocked, must move up. left, up, and right is open, check target, take closest path). only wildcard would be a dead end. edit, remembered this article, blog.danielwellman.com/2008/10/real-life-tron-on-an-apple-iigs.html same thing happens kindof, a light cycle escapes into "memory" and starts driving by weather or not random bits of memory looks like a wall or not and navigates that way. of course, that guy had the added quirk of rewriting whatever code it drove over.

@Justin-TPG 4 жыл бұрын
For anyone coming here wondering why the game counts tiles from the top right instead of the usual top left (and therefore why moving in a positive horizontal direction is calculated with a -1), this is because Pac-Man is a game which has the monitor rotated 90 degrees clockwise, making it vertically oriented. This provided a ‘vertical’ resolution of 288 rows instead of the 224 this hardware was capable of, allowing for the production of a tall maze. Internally, the game logic doesn’t change and the hardware operates as if the screen was in horizontal orientation, so when you move right, you’re really moving upwards. Conversely, when you move left, you’re really moving down the screen, hence this is calculated with 01 rather than -1.

The enemies' AI from 40+ years ago was already more complex than in most of the current games. Not even kidding. There are exceptions, sure, but how many times have we seen those cannon fodder cookie-cutter enemies that have two behaviors: 1. Hiding/shield up and 2. Shooting/shield down, most of them have literally nothing more in their virtual brains.
@WaxxyOne 4 жыл бұрын
The restrictions imposed by older hardware forced game developers to think outside the box and find creative solutions to gaming problems. By doing some very simple calculations, they were able to come up with four very different AI behaviors that made the ghosts seem smarter and less predictable as a result.

to simplify the ghosts’ chase behaviors, blinky simply targets the tile pac-man is on, pinky targets the tile four tiles in front of pac-man, inky works like blinky does except his target tile is affected by the location of blinky and clyde works like blinky too but he only chases pac-man if he is not within an eight-tile radius around pac-man
@astral2048 4 жыл бұрын
Really comprehensive! I'm going to try to make my own version of Pac-Man with the same mechanics now. I might leave the Pinky targeting offset bug but in all existing game-engines, it'll probably already be fixed (since they won't be using 2 bytes only and interpreting them as one 16-bit number). Also, most engines have pathfinding functions built-in to it. So I'll have to make that bug into a deliberate feature.

@danhouse1989 4 жыл бұрын
They did not fix Pinky for Ms Pac. The rest behave in a similar fashion but the programming issue wasn't fixed between the games since MS Pacman was a daughter board that was added on to a Pac Man. If you take off the daughter board and put a Z80 I think it was in its place, you can deconvert it back to Pacman.

Just a random connection I made... in PAC-MAN 99, about halfway through each match, arrows appear above the ghost house and the spawn area. I never knew what these meant until watching this, but it seems that they appear to signify that the intersection turn restrictions mentioned at 13:12 are disabled in order to eliminate the ability to exploit the ghost/jammer AI. I may be completely wrong about that, but if that is the case then that's pretty cool.

It's impressive that even if you don't know exactly how the AI works, they gave the ghost's their own personalities that sort of help you understand how they're gonna try and come at you. Pac-Man really was one of the first games with character and it ties in directly to the gameplay.

Great explanation of the artifact that I saw when writing pacman for the BBC micro. I implemented the pathfinding from a doc I found explaining it, so didn't have the overflow and always got the calculation "correct". John Studley, one of the perfect pacman players played my version and before long had found a place where you can sit and no ghosts will get you. I checked the original code and found the maths was "wrong" but have left it "as planned" in my version. Who would have thought a simple optimisation would have caused such a useful "bug". Maybe they knew, we may never know!
