The npc-wander demo uses a simple node base path where the position is used as a destination and turning is based on move direction. This produces a very linear path which is not good for situations such as camera fly through and cinematics.
The new path action uses a time base system in the same way a mesh animation works. This enables the path to be worked out in ms between way points providing control over movement such as walk then run and back to walk, also fun when showing a vehicle cinematic where you can go slow then acceleration or even pull a drift!
here is the dev area so far:
So far the action is following the arrows with the correct speed and orientation.
