Hi, I was wondering if the AI interface (specifically the Java interface), had a callback for when an enemy unit enters a given units range (either reclaim or attack). I know this event happens internally (for instance, when an enemy enters the range of a LLT, it fires on the enemy), but it would be cool to program an AI where builders automatically reclaim nearby enemies. Specifically, this would make sense for nano towers, since you would want them to reclaim nearby enemies. Any idea how to achieve this behavior?

there's an widget for that, maybe see how it does it (was it smart nanos?)

In case anyone else wants to know: the widget "Smart Nanos" does this and can be found here: http://www.springfiles.com/show_file.php?id=1011

In each Update() call it scans units in a range. It does not use any specific event (if would exist).

In the Spring Engine and Skirmish AI world:
Callback: AI ----requests-something-from----> Engine
Event: Engine ----sends-to----> AI

There were events for enemy unit entered radar and entered LOS in the legacy AI interface, there should be events in the other APIs too

But there are no events for unit entered attack or reclaim range.

If an enemy unit is not in LOS then the information should not be available anyway, thus the events would be pointless, as it would require a set of calculations be done. The whole point of the events is to avoid these calculations, but if they're done anyway then that defeats the point
