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.
