As with most people (such as http://forum.unity3d.com/threads/175348-Stuck-in-tutorial-Stealth-Project) I’m attempting to do this tutorial before spending $1500 on new software. The tutorial uses the Pro feature Directional Lightmaps, which seems like a very strange decision in an ultra-basic tutorial. I was able to use Dual Lightmapping, and it doesn’t really affect any of the underlying game mechanics, so I’m able to ignore that pretty much. However, with the newly-posted tutorials, it calls for baking a Nav-Mesh, which I discover is also a Pro feature. As a total Unity newbie, I don’t yet understand what the Nav Mesh is, let alone how it really works. Before I go any further with these tutorials, I was wondering if anyone would be able to tell me if the lack of meshes would totally break the enemy AI, making the game fundamentally broken? Or if there’s some form of workaround for Free users?
Obviously, the ideal solution would be a beginner tutorial which was aimed more squarely at actual beginners(!) Especially given the quality of the videos and assets. It seems a shame, as they’re otherwise very good. Failing that, however, an idea of how to work around the lack of a Navigation tab would be appreciated.
A navmesh is an invisible mesh that is laid over walkable areas that help an AI to keep from doing things like trying to walk into a wall. Haven’t watched the tutorial in question so I have no idea if there is a free solution. Look into A* or RAIN. I believe both of those offer a free version.
