## DDGame structure access
The main game state is a 0x98B8-byte (39KB) monolithic object allocated by
`DDGame__Constructor` (0x56E220). It is wrapped by DDGameWrapper (0x56DEF0).
### DDGameWrapper offsets (from wrapper base)
- +0x488 → DDGame pointer (the allocated 0x98B8-byte object)
- +0x4C0 → GfxHandler 0 (vtable 0x66B280)
- +0x4CC → PCLandscape pointer
### DDGame offsets (from DDGame base)
- +0x0024 → Game state pointer
- +0x0028 → Constructor param
- +0x11B0 → Task state machine pointers (5 entries)
- +0x3548 → Display mode
- +0x354C → Display width
- +0x3560 → Display center X
- +0x3564 → Display center Y
- +0x3578 → HWND
- +0x358D → Palette (0x400 bytes)
- +0x3D98 → Gfx object pointers (4 entries)
### WormKit-convention offsets (DWORD-indexed)
These offsets are from the DDGameWrapper base, as used by WormKit mods:
- DDGame+0x08 → TurnGame object
- DDGame+0x488 → Game global state
- DDGame+0x4CC → PC_Landscape
- DDGame+0x510 → Weapon table
- DDGame+0x548 → Weapon panel

## Fixed-point convention
All coordinates, velocities, and physics values use 16.16 fixed-point:
- `0x10000` = 1.0
- `0x20000` = 2.0
- `0xCCCC` ≈ 0.8
- Positions stored as Fixed at CGameTask offsets 0x84 (X) and 0x88 (Y)
- Velocities stored as Fixed at CGameTask offsets 0x90 (X) and 0x94 (Y)
