New BUILD map format

This page serves to collect and discuss ideas about a potential future map format for the BUILD engine.

Proposals

map-ng (helixhorned)

That is, pretty much the same thing as now, but with some fields rearranged for convenience, and others added.

• sector[] .ceiling*, .floor* --> sector[].cf*[2], indexed by YAX_CEILING (0) or YAX_FLOOR (1). So that less code is almost-duplicated. Downside: worse readability?
• sector[].cfbunch[2], to keep xpanning free

• Support for additional information (author, per-map settings, ...). The most general way of accomplishing that is packing scripting code that would be run on map entry (near/similar-to EVENT_ENTERLEVEL) into the map

map-text (TerminX)

Purely textual format, similar to the "Universal Doom Map Format" (UDMF).

Behavior of the editor

We'd still want to save old map formats on occasion, like when making test maps that need to be opened in e.g. Duke3D 1.5.
