This is great man I'm currently making a 2D platformer Roguelike and I thought this method would be best but I couldn't properly visualize it in my head, this helps a lot with proof of function and I will use this method and expand on it, great work!

Hi great solution I creating a side scroller platformer as well and I was wondering how did you implement this?

Hey ! Great video, I'm subscribing right now! May I ask how you overcame the middle knot path? Let me explain, I'm trying to implement your "all in one path" and I tried to start at the terminal nodes, but there are some nodes in the middle that are not on the best path depending on where the player starts. Did you run a* on all nodes in the grid? If you start with the terminals too, how did you solve this problem in the middle?

@Atrejooo

I can’t really help you with that because I don’t understand it. The video is very old and not well explained. It’s not A*. You can imagine the path go from everywhere to a specific goal. If you imagine the nodes as a maze on the ground. You can get the path by spilling water on the goal and write down the direction the water goes.

Possibly yes. I mean it isn’t really an ai. It’s more of an algorithm. But if you want

Hello, I'm a gamedev currently developing/playing around with a platformer idea. I love to make interesting AI for my games, however although I've never touched A* pathfinding I've developed other kinds of AI such as steering behaviours, etc. The thing is, when I got to implement it, I was surprised by the great tank in performance a SINGLE unit in my game produced by calling the algorith on every Update. Since you are one of the few that has implemented it on a platformer game in a flexible manner I wanted to discuss with you some fix I can make to boost the performance on my game. Since it appears that you feature MULTIPLE enemies at once on screen with their own brain. How can I get to tell you further details? Discord? Thank you for reading my comment btw.

I sent you a link to our sever. if you want we can talk over discod. But basically the performance can be improved by only calling the pathfinder everey few seconds. My techique is so fast becasue it just needs one path per target and not one per agent (if you know what I mean).

I assume enemies don't have infinite vertical movement, they can just jump and maybe double jump So why not close off paths that ask for too much vertical movement? Like with the diagram at 1:50 say a trail of red nodes that's more than some threshhold gets deleted because no enemy will be able to jump that high That would force enemies to take longer paths that are actually accessible

@Atrejooo

Good question. Each vertical waypoint which is directly above the ground stores the required Hight for the jump. Each agent the checks if there jump Hight parameter (its just a manual approximation) is enough. If not the agent doest jump. 👍✨

smart, I don't think this would extend super well to a level where you have 1 way platforms though or where multiple paths exist to get to the same place. Which is a shame... because I really don't like the typical enemies in most platformer games. Have you ever played sundered? I feel like figuring out what they did for their enemies that can climb walls would be a pretty useful thing for your game if you plan to add one way platforms.

@Atrejooo

Жыл бұрын

Nope no one way platforms. The system is best for my game in specific and can’t be expanded hugely.

so you loop through all the path node every frame or is there another way of it ?
