When I played Isaac years ago as a kid, I was amazed by how enemies try to surround you. I thought they had some kind of advanced AI, but this algorithm is so simple! I hope to see more videos like this :)

Damn, didn't realize simple things could seem so magical to people, haha. guess I should explain more things in other games as well. but it was a pretty good solution for trying to surround the player.

I recently decided from all my years of programming, protoyping, etc to commit myself to completing a game. I just happened to stumble across this, not only is isaac one of my favorite games but knowing how it works is going to be a valuable resource. Thanks for your videos, I look forward to future ones!

This series is actually helpful for game design in general. What happens when two numbers are the same? Which path is chosen?

@HimslGames 4 жыл бұрын

I guess it probably picks an arbitrary one, so you can probably see that there is on direction they would prefer if the paths are the same. maybe they always go up in doubt.

@Snaps12345 4 жыл бұрын

@@HimslGames You said if an enemy is there the number gets lowered even more but the number then was the same as the neighbor ones. Doesnt that still make the tile with the enemy on it a possible path?

The flies are quite interesting. I noticed in rebirth that it was quite easy to kill a whole swarm of flies by directing them into fires. They way they move in Rebirth is quite a bit different to the original.

so which is better? haha well guess flies going into fires is fun anyways.

If you were to re-program pathfinding for Binding of Isaac what names of techniques would you use instead?

@HimslGames 4 жыл бұрын

I guess I d have to see if A* can do the thing I mentioned about enemies being able to avoids paths other enemies are on. I guess the way I did it works fine actually. if it was in a more powerful engine it would not cause any lag at all.

If I could only play one flash game it would be Isaac so thanks for making it and would love to know what your interpretation of a sequel wouldve been if you had been in control

@HimslGames 4 жыл бұрын

I would ve liked to make a sequel where Isaac goes to hell and has to fight demons in a mashup between isaac and dark souls lol. probably not the best idea.

@@HimslGames That would be cool would it be a souls like or just in aesthetic? My vision for the future of isaac was one where he flies out of a chest as a demon confirming Isaacs mom's beliefs in a shocking twist.

Interesting. If you really wanted high performance which you might for a game you could try a threaded approach if the system ut's running on supports it. Multi-agent path planning algos can be complicated but the case here is relatively simple. What was written in?

@HimslGames 4 жыл бұрын

it was written in Adobe Flash XD. so no way to make it run much better. ^^

If the player breaks blocks with, say, bombs, will it update the map in each of the zombies' instance?

@HimslGames 4 жыл бұрын

only when it would normally... which is like once a second, so they wont instantly come after you. if I remember it right.

@johnmallard1910 2 жыл бұрын

According to what you said, the enemies would never surround the player, as they check only the surrounding tiles. (If their enemy buddy is further away, they don't see him and so enemies will group and go on the same path). Unless they plot a course beforehand?

@HimslGames 2 жыл бұрын

They see through each other, they just avoid walking the same way if they can.

@@HimslGames Thanks for the answer, but what exactly do you mean by "see through"?

@Legolegger 4 жыл бұрын

If I'm not mistaken, when enemies are packed together they will repell each other and Isaac so they don't overlap, similar to the flies but to a lesser extent. Is that the same principle the flies use?

@HimslGames 4 жыл бұрын

if we re talking physics, they are the same for every object yes. I don't know if zombies would avoid each other using AI tho.
