Roblox's Pathfinding Sucks...

Yeah, stuff like the crappy random zombies in games where you mass kill things such as enemies. (such as survive and kill the killers in Area 51) They simply just walk to the nearest players direction and that’s it, so idiotic, can’t even avoid obstacles.

[@pwf2k]

Roblox engineers have to make a lot of generalizations. One example I can see is how the custom characters are walking horizontally. Roblox assumes the character is effectively a cylinder with whatever height and width given by the developer, so it doesn't find the path in that scenario. Not to mention the custom pathfinding is a snail compared to the built-in nav mesh to generate. It takes skill to optimize something like that to be that fast well.

[@Minecraft-hb1su]

Roblox definently could fix it, they just choose not to.. as doing so would not result in a profit.. and thats why I stopped using it as a game engine.. so much more freedom and control with unity and C#

@@Minecraft-hb1su they don't need to do a lot of the things they do just for a profit, in fact it frequently results in problems for them when they try to revamp something, like the Talent Hub or the Developer Docs. People said that the original versions of those 2 were better than the current one, and Roblox sure as hell isn't making any money by making mistakes by trying to modernize. What does Unity's built-in navigation do better than Roblox's? And "Roblox is a terrible game engine"? Unity doesn't have Humanoids, data storage, free online servers and all, so Roblox is better than Unity in many ways. I have yet to see a game that can't be recreated in Roblox.

Honestly the PathfindingService is one of the most confusing APIs I've ever tried using. I mean I could wrap my head around it eventually but it just feels like such a pain to do every time I have to deal with it. But that doesn't mean it's less efficient than this video's way. I'd rather figure out a way by spamming raycasts and then hoping it would be a more versatile system while hopefully being just as efficient

You can edit the player module to make it climb.

[@verygood2236]

Roblox pathfinding is really designed for common and generic cases, it also saves a lot of process because they clearly chose a more amplified grid that does not allow it to be precise, there is no perfect pathfinding, you can do it to your liking, make a 3D pathfinding that is compatible with everything is expensive, but if your game is only handled in X and Z you can do a much simpler 2D path finding.

[@gsck5499]

The issue with roblox's pathfinding is it uses a pretty crappy low-resolution navmesh, each vert is on a 4x4 grid. Idealy, and how every other game engine ever does it, it should just get the level geometry removing any faces that are at too steep an angle and connecting any islands where possible. Your method, although it works is a pretty poor implementation, using a basic grid-based flood fill algorithm which is less precise only being able to go to specific points and is slow.

[@UltimaDoombotMK1]

And even though it's a bad implementation it's better than Roblox's in built one. Really speaks to the quality of their game, huh?

[@gsck5499]

@@UltimaDoombotMK1 not really, just because this guys implementation works doesnt make it any better that Roblox's built in one. They are for 2 very different use cases, Roblox's is good for generalised open world pathfinding. This guys is for tight maneuvers nothing more.

Dang how did you get it that fast? I was working on a 3D flood fill for reasons and I couldn't get it faster than render stepped (or heartbeat I forget which one is server side) Is it just because you are using 2D and so its faster due to that?

[@eleos5]

Yes, one of the reasons is because I was using 2d, but you can actually be faster than heartbeat. If you count each time you loop in your while loop, you can check if the count is divisible by 5, and put the wait in there. Every 5 loops you will wait instead of every loop. You can do this by doing (if n % 5 == 0 then). % is like / but it just returns the remainder.
