The QB programming language.
----------------------------------------------------
NeverScript is a programming language that targets Neversoft's custom scripting engine (QB).
This project contains:
- A
NeverScript -> QB
compiler. - ~A
QB -> NeverScript
decompiler~. - A
PRE
/PRX
generator (QB files are usually bundled into PRE/PRX files).
These tools are intended to work with games such as:
- Tony Hawk's Pro Skater 3 (THPS3)
- Tony Hawk's Pro Skater 4 (THPS4)
- Tony Hawk's Underground (THUG1)
- Tony Hawk's Underground 2 (THUG2)
All of these games use variations of Neversoft's scripting engine. Personally I've only tested against THUG2 and THPS4, but I'm sure compatibility with other games can be improved with time.
Getting started
- Download: latest release
-
Syntax guide:
- Best way to learn is by reading neverscript.ns which gets compiled by the tests.
- Or by reading this outdated document.
Other useful resources:
- Blub scripting guide by Morten: http://www.thps-mods.com/forum/viewtopic.php?t=806
Usage
Compiling a NeverScript file:
$ ns -c path/to/code.ns
This will create a new QB file: path/to/code.qb
- Use
-o path/to/output_file.qb
to change the name of the generated file. - Use
-showHexDump
to see the bytecode generated by the compiler. - Use
-showDecompiledRoq
to see output from the roq decompiler (blub syntax). - Use
-removeChecksums
to remove checksum information from the generated file. - Use
-targetGame
followed bythps3
/thps4
/thug1
/thug2
to target a specific game.
Decompiling a QB file:
Not implemented yet.
Generating a PRE/PRX file:
You can generate a pre/prx file by providing a pre spec.
$ ns -p myPreSpec.ps -o bundle.pre
This will read the pre spec from myPreSpec.ps
and create a new PRE file: bundle.pre
- Use
-showHexDump
to see the bytes of the pre file.
What's a pre spec?
This is a text document containing many "items".
Each "item" consists of:
- The source path (the file to bundle).
- The destination path (inside the pre file).
Here's an example of a pre spec containing 4 items:
C:\mod\build\qb\_mods\byxor_debug.qb
qb\_mods\byxor_debug.qb
C:\mod\build\qb\_mods\byxor_menu.qb
qb\_mods\byxor_menu.qb
C:\mod\build\qb\_mods\byxor_math.qb
qb\_mods\byxor_math.qb
C:\mod\qdir.txt
code\qb\qdir.txt
Note
- Only pre version 3 is supported at the moment.
- None of the items inside the pre file will be compressed.
- You can use relative paths too.
