Basic AI Pathfinding

[JJJohan]

After spending more time than I'd like to admit figuring out the entity and object linkage was a little broken (Basically had to use the same label 'decoding' process as described on That Tony's blog), I managed to get a basic version of the AI pathfinding working.

Video of the exciting stuff in action:

There's a few little nitpicks I'll just mention up front:

• In the original game, AI follow paths through the road network. In this version, the AI only use the paths with no interaction with the roads themselves yet.
• Because of the above, the two cars that spawn on the cliff will helplessly drive off the cliff not long after spawning.
• The AI driving is a bit of a "this seems to kind of work" implementation 😉.
• You'll notice the Piranha jittering a bit in the video - this is simply from the FixedUpdate physics and the Camera Update not really syncing together well, but appears fine in the Scene view.

There's a few miscellaneous tidy-ups sadly the file count got a bit out of hand after enabling text serialisation for Unity project settings, the commits themselves are still small enough to review individually.

Quick update - pathfinding now uses the road system. New video showing cars being able to handle corners and recovering somewhat after colliding with each other.

I'm trying really hard to contain my excitement here.. Wow! This is awesome!! I'm sure it's fine but just gonna test it out anyway before merging it.

I'll try to at least keep future pull requests from changing half the project's files so it's a bit easier to see what I've done 😛 .

That's awesome! Very exciting stuff. :)
