Jason Patrol
| Address | Description |
|---|---|
| 0xB62F | Multi-byte list containing Jason’s patrol route |
Most of it is a sequence of 2-byte pairs. If the first byte is 0xFF, that’s a special case.
Byte 1 & 0xF0: Id of zone
Byte 1 & 0x0F: ‘Section’ of zone. Sectioning of zones is TBD. There’s logic in the game (0xBA3A) which determines if the counselor meets Jason in the same section which can be used to flesh this out.
Byte 2 & 0x1F: ID of cabin Jason will enter (or 0 if no cabin)
Byte 2 & 0xE0: Dwell time of Jason at location (number of 0x50F ticks to countdown)
The major pointer into this address is the 0x50D-E pair.
When first entering the game proper, the frame counter 0x31 is used to ‘randomly’ initialize where 0x50D-E initially points.
That pointer is updated each time Jason moves.
If Byte 1 is 0xFF, then the next two bytes are used to update the value of the 0x50D-0x50E pointer.
