Parallel animation and move not working with waypoint networks (prob my fault!)

[tapticcParticipant]

Hi, I am having trouble using a waypoint network and animating using a mecanim parameter for speed which increases over time, rather than jumping from zero to one.

Basically my “Nerd” is supposed to move near to one of the network points in a random path. This works fine. The Nerd is also animated by setting a mecanim parameter to 1 with a damp time. I can’t get the damp time to trigger multiple times in the tree even though I am using a parallel action. If I set the animation speed to repeat the move only fires once so the smooth acceleration works but the character stands still. Am I using the wrong approach entirely?

I have no idea why the links to screen shots, xml and .cs file are not showing by the way!

}

public override void Start(AI ai)

}

return ActionResult.SUCCESS;
}

public override void Stop(AI ai)

base.Stop(ai);
}
}

Not sure I can tell what’s up without seeing a bit more. If you have a way to share a sample project, that’s usually most helpful.

RAIN 2.1 supports damping of speed directly in the Mecanim Motor. So, you could just set the damping there and then use a Move node directly.
