How would I start making a custom pathfinding system?

[richithebest123 (Alternative)]

Hello there fellow developers, I am having problems with pathfinding in my path less tower defence game. As lots you may know that the pathfinding system in roblox is very bad and does not work with coroutines and task.spawn() or it doesn’t work in my case.

So I would like to know how would I start off with in creating the ai system. The ai doesn’t need to jump. Can work with multiple enemies at the same time. It also has to be able to change its target midway through it way. And I don’t want to use raycast as it would lag the game alot and another person said it’s inefficient.

I would like to discuss this topic.
