Topic: Location Triggers - Decoded

[Grimoire LD]

These past few days have been spent completing the Location Triggers.txt created by Yousei and improved upon by Phoenix. In this there is every treasure, map loading, and event in the game for simple and easy modification without having to use external tools to find addresses and the like. The addresses are all present right there, but you will need to use a tool like FFIV Tools to move treasure chests to their new location.

In finishing up this project I used Zyrthofar's map viewer Extensively, since it shows you what is inside each treasure chest and what (hex number) map tiles lead where. In addition to discovering all of the Location Trigger Events and other assorted things was done through FF4kster so I could easily change events and add flags and the like to test certain Required Event Flag - Tile Events.


If you have any questions I'll do the best to answer them, but in the meantime here it is. I hope that this will be of help to PinkPuff in creating a comprehensive and well detailed FFIV Editor.

Oh, before I forget here are the Location Trigger Event Order (since they differ substantially from the normal event order).

Some tile events require Event Flags to activate, as such I'm not sure what each event flag corresponds to, therefore many of these will likely incorrectly remain "Nothing?")
14 -(47)Yang joining, Mombomb Battle

That first part of the post isn't very accurate. It turns out that Phoenix also knocked those out of the way with a much more empirical method than "Test and see" but by finding the data. So here's a more accurate portrayal of tile events and what and when they link to their tiles.


Phoenix's Info on Event Triggers

(*REF - Required Event Flag)

======================================================================================
Event Triggers                                             Phoenix Hacks
                                                   12/22/09

======================================================================================

Map tile triggers reference event triggers. The pointers for these triggers are
located from 97460 to 9765F. To find where these point, reverse the bytes and
add 0x97660. The event trigger data is located from 97660 to 9785F.

======================================================================================
FFxx = Load event xx
FEaa = If event flag aa is set...
aa = If event flag aa is clear...

Examples:
aaFFxxFFyy = If event flag aa is clear, then load event xx, else load event yy
FEaabbFFxxFEccFFyyFFzz = If event flag aa is set and bb is clear, then load event xx,
          else if event flag cc is set, load event yy, else load event zz

The event trigger data, like the NPC speech data, utilizes events numbers 01-03,
which are EE message calls: "Show message [hex data xx following event call] (from bank 2)"
For example, the Old Man wandering in the town of Baron has the following data (at 99EDE-99EEA):
   FE 06 FF 03 FE 0B FF 02 FF 01 03 04 05
This translates to:
   Data      Meaning
   --------   ------------------------
   FE 06      If event flag 06 is set,
   FF 03      load event 03 (i.e. message call EE 02 = message 05 of bank 2)
   FE 0B      (else) if event flag 0B is set,
   FF 02      load event 02 (i.e. message call EE 01 = message 04 of bank 2)
   FF 01      (else) load event 01 (i.e. message call EE 00 = message 03 of bank 2)
   03 04 05   [Hex data following event call]
