Blizz did do something very smart with his ABS, and that was provide information to the community so others could expand on his battle system.
The sensors that I used are almost the same as Little Drago's sensors, but without all the rest of the stealth and view related stuff. It is possible that Blizz ABS could be expanded to work with a Blizz ABS specific type of Sensor. All Sensors really do is enable a Game Switch that causes the Event to change Pages. Like you said, I dont have any experience in scripting for Blizz ABS, but ten bucks says that Page Changing can probably be compatible with Blizz ABS for causing different types of behaviors.
If Little Dragos Simple Event Sensors scripts works okay with Blizz ABS, it is probably a better foundation to build on than mine, as it was never designed for Combat, but only to trigger the default or other non map related types of combat systems.
Just so everyone knows this...
