Ok I plsyed with the a * pathfinding system a little.
And now I am learning rain.
My question is if I use the third party system do I need unity pro ?
I been reading a lot about pathfinding and I am finding that navmesh seems to be the way to go.
Another side note… why did unity lock down key gameplay features in free vs pro ?
I think they should of locked down shaders and things that polish the game not key game function s like nav meshes.
