Warp Triggers
Overview
When the player steps in a specific coordinate in the map, he is transported in a new map with new coordinates.
Offsets
| Description | Value |
|---|---|
| Base offset (SNES) | $DFBB00 |
| Block size | $02 |
| Number of blocks | $01A0 |
| Total size | $0340 |
The structure is a sequence of two-byte pointers. The index of the pointer is relative to the map number.
The actual offset of the appointed data is the pointer value plus the base offset.
The game system checks the actual pointer and the next pointer to determinate the amount of data to read. It can include multiple data blocks.
Data
| Offset | Mask | Description |
|---|---|---|
| $00 | $FF | x position, actual map |
| $01 | $FF | y position, actual map |
| $02 | $FF | new map, low byte |
| $03 | $01 | new map, high bit |
| $02 | ? | |
| $04 | ? | |
| $08 | display location name | |
| $30 | direction facing | |
| $40 | ? | |
| $80 | ? | |
| $04 | $FF | x position, new map |
| $05 | $FF | y position, new map |
Notes
The coordinates of the new map must be valid. Otherwise, the player can be stuck in a no-walkable tile and unable to move. Also, the warp system won't work correctly if the new coordinates bypass the new map maximum coordinates.
