....[2] In character based systems, narrative knowledge is not explicitly represented, and the development of the story line is within the responsibility of autonomous agents. In order to insure narrative control, autonomous) characters behavior is described in terms of roles (Cavazza et al. [16]) For an extensive discussion of competing approaches to interactive narrative, the reader is kindly referred to the paper of Spierling et al. 46] 7. Conclusion Recent years have witnessed a growing interest in lifelike, believable characters as a crucial component of enhanced learning, ....

....mechanism so as to obtain a real time version interleaving planning and execution. HTN implements forward search from the goal state which brings the unique property that during planning itself the state of the world is known at all times. We have given several descriptions of our HTN planner [2] [3] [4] and will rather concentrate in the next sections on the representational aspects. Fig. 1. HTN representation of lead character behaviour. Authoring an HTN can be seen as the description of a character s role in a traditional sense. Its actions have to be decomposed into lower level ....
....that the plan is compiled but that its higher level goals are fixed, flexibility and generativity taking place at the lower levels. As discussed in section 2, narrative interest comes from action failure within this pre defined plan, either due to user intervention or interference by other agents [3]. Conversely, with HSP planning, the agent is generating its own plan from a single narrative drive equivalent to the HTN s top level goal. Under these circumstances narrative interest can derive, not only from external interaction but also from the qualities of the plan assembled. Basically, ....

....the use of planning systems to control characters behaviours. Geib [5] has proposed the use of refinement planning following a detailed study of animation requirements [5] 8] Funge has used situation calculus to generate intelligent behaviours for virtual actors [4] and Cavazza et al. 2][3] have approached this problem with Hierarchical Task Networks (HTNs) for storytelling, considering the knowledge intensive nature of this kind of applications. The planning requirements for virtual actors depend on the specific application, however we can identify these essential requirements: ....
....to investigate with a non decomposable, non empty deletelists planning problem on a similar application unlike the second example. The second example provided introduces the potential of HSP as a technique for story dramatisation, which is based upon earlier work into interactive storytelling [3]. In the story presented, the lead male character is attempting to ask the lead female character on a date his plan should take him through the appropriate set of actions to achieve this goal (e.g. acquiring her gift preferences, getting the gift, getting her alone, etc. Because the various ....
