| ## 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) |
