2D Pathfinding help

Hi, I'm interested in integrating pathfinding into a 2D rpg game I'm making. Now, I don't really want to just use an asset that someone has made; I want to learn how to do it myself So, where would I go about learning how to do this with Unity specifically? I know how to make a pathfinding/search algorithm (I had to trundle through a D1 module in Further Maths AS) but I just don't know how I would implement it into Unity. It's nice and easy to write it in Pseudocode ("Compare the distance from the objects current position to Node A and Node B") but it's a lot harder to do that when you're creating worlds with 1000s of tiles that each act as separate nodes :/

Thanks!

 

So each of your tiles are "nodes" right? In that case, you should know which ones are passable and not. Look up A* or Astar path finding algorithm for how you would make effective pathfinding. Create a script that contains all the functionality and send in your tiles/nodes for reference. If implemented correctly, you can tell the algorithm to say "hey, I'm at node 0, I want to go to node 3298", and the algorithm finds the "path", each node it has to pass through to get from node 0 to 3298. Then it's just a matter of moving your object towards the node position, and when your object gets close to it, change to the next one in the list until you're done.

 

@ElAshtonio I have implemented just that for our game. Hopefully my video of it could help you out. You are free to use any code I have in the video or in any other videos.
