Paper Abstract:
|
The main concept behind Role-Playing Games (RPGs) is to provide the user with a wide variety of decisions so that a single problem can be approached in different ways. The choices present for the Non-Playable Characters (NPCs) are however quite limited and their actions are mostly dependent on the actions done by the user. The NPCs do not normally have their own objectives to complete, therefore their actions do not appear natural. The do not have objectives to complete which limits their interaction thus reducing their impact on the overall game world. The authors propose a system where every character has some specific objectives which can be achieved by formulating a plan. The successful application of the plan is dependent on the ability of the NPCs to perform the actions contained in that plan. For the achievement of the objectives a multi-step decision making process is used which evaluates the possibility of performing actions at every level of the graph. Depending on the actions that a character can perform and the orientation that the character has, the outcome can be different under the same circumstances. This in turn causes the game world to change not only due to the actions of the user, but also due to those done by the NPCs. |
