DDGame structure access

The main game state is accessed through the DDGame pointer:

• DDGame obtained via ConstructDDGameWrapper (0x56DEF0) parameter
• 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)
