GZDoom 2.3.2 released

Posted by Graf Zahl on 10 January 2017 at 16:42.
This is a bugfix release addressing a few critical issues in 2.3.1:

Critical issues fixed:

- turbo stairs in Doom 2 were broken
- potential crash with stair building in Hexen
- The Heresiarch in Hexen did not call its death script.
- several Heretic weapons behaved incorrectly.
- The last two were caused by an incorrect script compiler check that failed to detect a bad function definition. This may induce a breaking change to some ZScript based user mods, too, which made the same mistake!

Other fixes:
- fixed a problem with drawing decals with the software renderer.
- 'stat music' could crash on OpenAL
- fixed a rare crash condition with killing monsters from the console.
- the spiral for railgun shots wasn't drawn.
- switching from windowed to fullscreen could set bad screen sizes not covering the entire screen.
- fixed sight checks through portals.

New features:
- mods can define items globally for precaching in addition to per-map definitions

WadExt v1.0 released

Posted by Graf Zahl on 10 November 2016 at 11:55.
I finally got tired of the problems with the existing extraction tools so I decided to write my own.


This is a simple command line tool that will extract an entire WAD into a mostly PK3-compatible folder structure, it will also decompile all TEXTUREx, ANIMATED and SWITCHES lumps into readable and reusable text lumps (ANIMDEFS and TEXTURES, respectively.) Most of the file formats used with ZDoom will be detected and get a proper extension applied.

Doom format graphics and sounds will be converted to common formats PNG and WAV, this can be disabled via command line.

Comments and suggestions are welcome. Please add any bug reports and feature suggestions to the Github tracker if you have an account over there.
Currently only working on Windows, if someone wants to make it work on Linux or maxOS, please drop me a line so that I can add you to the repo.
