A* Pathfinding Project with composite colliders.

Question

I have no experience in A* AI creation so I found this asset that does the A* work for me. The problem is after some testing, the composite collides that I work with do not register to the A* grid generator. This is most likely due to it being new but I was wondering if anybody had some alternative or could link me to site that could teach me basic grid A* for a beginner.

Thanks ahead of time, this community is wonderful.

The trick is to set your composite collider to be of type polygon, not bounds. For some reason Bounds doesn't work with A* Pathfinding Project (Solution from https://old.reddit.com/r/gamedev/comments/o5v0ki/solution_regarding_the_usage_of_a_star/ ).
