A* Pathfinding question

#1

Hello there,

I’m trying to implement the A* plugin into this tutorial since you suggested it.
However, I cannot for the life of me get the Unit’s to stop walking through my walls.
I did follow the level creation and object implementation tutorials to make sure things were set properly.

I did make sure to follow the quick start tutorial on A*s site as well as using CodeMonkey’s tutorial.

I’m assuming all I need are the scripts from A* and nothing from here.
I have no pathfinding scripts made up from this tutorial btw, so Im hoping that doesn’t matter.

Make sure you’re using the right graph, that asset has tons of graph types, from 2D to 3D. I included a quick getting started guide in the end of my review video The PERFECT Pathfinding! - Code Monkey
Basically you just need the Grid in that tool to be with the exact same shape/size as the GridSystem in the game.
That tool uses the same logic for identifying walkable and unwalkable areas as I used in the course code, it does a Raycast, so it should work pretty much exactly the same.

So I’ve been trying everything, they still walk through walls and the grid we made here still shows up and such. What would I need to do for a 3D top down game like this?

Do the walls have Colliders? Are they inside the A* Pathfinding bounds? What happens when you click on Scan? Look at the video I posted at 04:00
That’s really all you need to do, that and make sure the grid shape matches.
