endPoint);

end

Soldier_SetPath(userData.agent, path, false);
userData.agent:SetTarget(endPoint);
userData.movePosition = endPoint;

Once a valid target position and path is found, the flee action acts very similar to a move
action with one exception, which is health. As our flee action continues to move our agent
until it reaches the target position, we must check whether the agent is still alive; other-
wise, we have to terminate the action early:

SoldierActions.lua :

function SoldierActions_FleeUpdate(deltaTimeInMillis,
userData)
-- Terminate the Action if the agent is dead.
