Detailed Description
Priority queue of timed callbacks. Drives all game timing.
Every action duration (movement, incantation, starvation...) is a scheduled callback. The server feeds msUntilNext() directly to poll() so the process sleeps exactly as long as needed: no busy-waiting.

◆ clear()

Here is the caller graph for this function:◆ msUntilNext()
| int Scheduler::msUntilNext | ( | ) | const |
Milliseconds until the next event. Pass directly to poll() as timeout. Returns -1 if the queue is empty (poll blocks until I/O arrives).

Here is the caller graph for this function:◆ rescale()
| void Scheduler::rescale | ( | float | ratio | ) |
Rescale all pending fire times by ratio.
Called when the GUI sends sst T to change frequency. Pass oldFreq / newFreq. O(n log n) heap rebuild – acceptable since sst is infrequent.
