entity and particle functions and physics are stopped,
causing the level to
freeze completely. Resetting the variable to 0 will cause
all stopped functions to resume at the point when freeze_mode
0 - All functions are running normally (default).
1 - Entity functions (my != NULL) and particle
functions are paused.
2 - All functions are paused,
except those that had proc_mode set to PROC_NOFREEZE.
4 - Particle
functions are paused and particle lifespan does not count down. 8.50
