|
| Recently, many AI researchers working on interactive storytelling systems have turned to off-the-shelf game engines for simulation and visualization of virtual 3D graphical worlds. Integrating AI research into game engines can be difficult due to the fact that game engines typically do not use symbolic or declarative representations of characters, settings, or actions. This is particularly true for interactive storytelling applications that use an AI story controller to subtly manipulate ... |
