Support for record / playback #192

Open Raincloud7 opened 5 years ago

Raincloud7 commented 5 years ago

I could not find any information on the new record playback commands.

Looking at the decoded file (and identifying the ids) i see this:

  3290:  // record
  - $0==1? $2:=3290 $4:=0
  - $0==2?
  - $0==3?
  - $0==4?
  - $0==5?
  - $0==6?  
  3291:  // play
  - $0==1? $2:=3291 $4:=0
  - $0==2?
  - $0==3?
  - $0==4?
  - $0==5?
  - $0==6?

which does not make sense to me. Variables $2 and $4 are not used otherwise as it seems. Did anyone manage to build custom books with recording / playback.

There are quite a few holes in at least Die verrueckte Weltreise.gme(meaning parts of the file that are not understood by tttool):

My guess would be, that tttool does not understand the new record and playback commands, so they don't appear in the exported file.

Here are some OIDs that record and play back in that file (first code for recording, second one for playback), if that helps with examining the file:

* `3218`, `3219` sorcerer, record slot 0001 * `3221`, `3222` sorceress, record slot 0002 * `3226`, `3227` bird, record slot 0003 * `3237`, `3238` unicorn, record slot 0005 * `3245`, `3246` sheep, record slot 0006 * `3248`, `3249` ear, record slot 0007 * `3252`, `3253` owl, record slot 0008 * `3257`, `3258` iceman, record slot 0009 * `3270`, `3271` girl, record slot 0010 * `3274`, `3275` boy, record slot 0011 * `3278`, `3279` dog, record slot 0012 * `3286`, `3287` clown, record slot 0013 * `3290`, `3291` knight, record slot 0014 * `3294`, `3295` horse and pig, record slot 0015 * `3301`, `3302` dragon, record slot 0016

The last two are mostly addtional gametables as referenced at 0xc8 and 0xcc. Looks like tttool does not know about them. We do not know why we have several gametables but as the structure is known I'd say at least tttool explain and tttool holes should respect them!

@Joachim: I'll open an issue for that

A did some check with random OIDs on that gme file. For every OID I checked (3290,3291,3292,3295,3495,308,3904) $2 is always set to the OID. So I guess $2 is something like "last selected OID". And $4 is always set to 0.
