Lua:Callins

Lua Callins

This page is future looking to unified widget/gadget (aka "addon") handler, which may yet be some way off, c.f. the changelog.

Some functions may differ between (synced) gadget and widgets; those are in the #Synced_-_Unsynced_Shared section. Essentially the reason is that all information should be available to synced (game logic controlling) gadgets, but restricted to unsynced gadget/widget (e.g. information about an enemy unit only detected via radar and not yet in LOS). In such cases the full (synced) param list is documented. <a href="http://imgur.com/Gr5qnAx"><img src="" title="source: imgur.com" /></a>
