Timing Globals

​
Delta Time

Base: 0x00480840 (delta_time)
Type: float Frame delta time in seconds (typically 1/60 ≈ 0.0167). Usage: Multiply by this value for frame-rate independent movement:

​
RNG State

Type: u32 CRT rand() state. Updated by crt_rand() @ 0x00461746: 
int crt_rand(void) {
    rng_seed = rng_seed * 214013 + 2531011;
    return (rng_seed >> 16) & 0x7fff;
}
Seeding: Initialized with time(NULL) or explicit seed for deterministic replays.
