CDecor

Header: include/decor.hpp (~642 lines)
Implementation: Split across 8 source files

CDecor is the central game engine class in Free Eggbert. It manages the entire game world — the 100×100 tile grid, all moving objects, the player character, game logic, rendering, save/load, networking, and the level editor. Everything that "is the game" lives here.

Player State Model

Unlike the Planet Blupi engine which uses a Blupi[100] array for up to 100 simultaneous characters, Free Eggbert stores the player state as individual member fields directly in CDecor:

In multiplayer, up to 4 players are tracked through the NetPacket stream; each player sends their own position and state each game tick.

Moving Object System

The moveObject[200] array (type MoveObject[MAXMOVEOBJECT]) tracks all active enemies, bombs, vehicles, collectibles, and effects in the level. This array is managed primarily in src/decmove.cpp.

See Object Types Reference for all TYPE_* values.

Save/Load

src/decio.cpp serializes the complete game state — including the world grid, all moving objects, and player status — into a DescSave struct (~56KB). Up to 6 save slots are supported.

Level Editor

src/decdesign.cpp implements the built-in level editor. Activated via WM_PHASE_BUILD.
