DrawField is a variant of DrawDungeon. Unlike the first-person
perspective of DrawDungeon, DrawField uses a third-person, bird's-eye
view camera.
Key features include:
- Character Rendering: A new system to render up to 256 billboarded
sprites (characters, enemies, etc.) in the 3D world. The renderer
supports controlling position, sprite animation, and visibility for
each character.
- DrawField HLL API: Functions for loading assets, managing characters,
and manipulating dungeon properties like door locks.
- Renderer: The core renderer is updated to support the DrawField mode.
This includes disabling fog, handling sprite sheets via UV
manipulation, and rendering ceilings as billboards.
- Map: The 2D map has been updated to reflect the DrawField style,
including colored door lock indicators.
* Cells loaded from walk-data are half-transparent.
* The player symbol is half-transparent when showing different floors.
* Clear the texture before drawing a small map so that no garbage is
left when the drawing is clipped.
Major differences from DrawDungeon.hll are:
- DGN, DTX, TES are loaded from individual files, not from a DLF archive
- 2D map functions are not used
- (unimplemented) Spinning motion of event markers
- (unimplemented) Additional 3D object types (polygon models and roofs)
