DSB/Subrenderers

A subrenderer is a special Lua function that renders the large area in the lower-right corner of the inventory screen. In the default code provided in base/, subrenderers are used to create the chest and scroll, and concievably about anything else could be built.

See the stats and inventory screen renderers in base/render.lua for more information on subrenderers. (Another place to look is the implementation of chests and scrolls in base/objects.lua)

By default, a subrenderer is called 6 times a second, as well as any time it is clicked or interacted with.

Any efforts to reconstruct the Amiga CSB magic map are quite welcome.

Callbacks

Some callback hooks that may be useful while working with subrenderers:

inst_outgoing

something gets removed from a container

inst_incoming

something gets added to a container

on_unlook

called after an item is removed from the hover-on-eyeball examination

after_from_r_hand

called after an item is removed from the active hand, which will close those subrenderers
