Character driven by a curve.
Now, the moving along the walk cycle (LocX Loc Z ipos) is supported by the reference object instead of the character himself. This reference object moves along a curve allowing to create individual curved trajectories for the character.
This method shows that only 3 simple objects are necessary to make a walking character :
2-The reference object (a small triangular face).
3-The curve used as trajectory.
One curve can support as many character as you wish.
The characters can all follow the curve une after the other, or walk all in the same direction in straight line. In this case, they can be everywhere, not only on the curve.
