I thought I'd share what I've got so far in case anyone else is interested. It's quite fascinating reading through them... or at least I think so.
I've been able to extract every script I've found so far, the only thing lacking in the output is proper display of all the different variable types. Halo has around 50 different types, so far I've only coded in support for the basic few (boolean, short, long, real, etc), the rest are shown as hexvalue:type, e.g. ffff0051:vehicle. The hexvalue is either a tag id, or, as in this example, an index to one of the various reflexives in the scenario. Therefore ffff0051:vehicle means the vehicle referenced in the 0x51st chunk of the vehicles reflexive.
I might get around to supporting most of the types if there is enough interest.
Here is a sample from b40 (AotCR):
Code: Select all
(global boolean global_dialog_on false)
(global boolean global_music_on false)
(global long global_delay_music (* 30:real 300:real))

(global boolean debug true)
(global long default_turret_delay (* 30:real 10:real))
(global long control_turret_delay (* 30:real 10:real))
(global short exterior_player_location 0:short)
(global boolean mission_start false)
(global boolean a1_spawn true)
(global short a1_spawn_counter 0:short)
(global short a1_squad_index 1:short)

The functions you see such as sleep, or switch_bsp are defined in the xbe, rather than the map. I've attached a list of these along with descriptions of what they do.
As for compiling (recompiling), I don't think it's going to happen any time soon. Arsenic is supposed to have a script compiler in the works and I'm far too lazy to waste time on duplicating the enormous amount of work it'll take to get compiling to work.
I'm open to requests for features, maps to decompile, or whatever. I don't feel like releasing the program or code at the moment though.
Thanks to:
Soldier of Light & the other members of Brok3n Halo who worked on the original Halo 2 scripting tutorial.
Mike (aka xbox7887) for the xbe script list.
Note: The xbe scripts and their descriptions were lifted straight out of the xbe, all the colourful language belongs to Bungie.
