Goal Provide a simple visual tool that

enables a game designer to generate a complex story for a computer role-playing game (CRPG)

These games are the next generation technology for interactive entertainment

They transform linear written stories into 3D interactive adventures

Step 1: Aurora Toolset – Create the World The module is created using the

Aurora toolset We create a room, we place a chest, a

tree, a non-player character (NPC), a cold damage source, a tree light, a chest light, a chest

Any other suggestions?

Manual Scripting vs. ScriptEase CRPGs involve large virtual worlds

with thousands of characters Designers often need programmers to

write their scripts We provide designers with a visual

scripting tool based on patterns: ScriptEase

Example: pull lever - open door

10

ScriptEase Abstraction Patterns are recurrent themes in stories They are re-usable and independent of a

particular story Each pattern has options (a specific lever, a

specific door) The designer only chooses the pattern and

picks the desired options relevant to the particular story

ScriptEase generates the code automatically

11

Sample Patterns Encounter Patterns

Item Container Barrier Perimeter Damage Source Use Placeable Open Container

Behavior Patterns: Guard Bar Scene – (work in progress)

Plot Patterns Dialog Patterns

12

Step 2: ScriptEase – Write the Story The module is scripted, i.e., the story

is written We add several patterns, such as

open chest – spawn creature, enter/exit trigger - barrier

Any other suggestions?

Step 3: NWN - Play!

Conclusions The stories are created by game

designers, not only by programmers using ScriptEase

ScriptEase provides the means to write stories in a non-linear manner
