Welcome to EDGEROTT!

Fork of rottexpr to further integrate and enhance ROTT backend support into EDGE.

Port of rottexpr to EDGE

EDGE is an advanced OpenGL source port spawned from the DOOM engine, with focus on easy development and expansion for modders and end-users.

Support

Visit the EDGE forums and get involved with the community and the various projects for the engine.
The EDGEWiki is also a great resource for editing documentation and other information related to the engine.

Currently In-Progress

Remove Makefile support, use CMake instead
Total refactor of code, to follow EDGE conventions (file renames to better organize code, merge/removal of unused files, swap places/names of many functions)
Convert codebase to C++ (98/2011 at least), and completely get rid of the wonky "private" headers (prefixed with _)
Remove/strip/convert many local functions to use EPI backend instead

Goals

RENDERER: Convert rendering/SDL2 code to OpenGL-only
MODS: Update WAD code to EDGE, and using physfs, enable archive support for EPK/PK3 for mods and main EDGE.epk data (following EDGE EPK standards)

rottexpr Readme

Based off of the icculus Rise of the Triad source port (can be found here: https://icculus.org/rott/)

This source port of Rise of the Triad features the following:

Now runs off of SDL2!
Support for resolutions from 320x200 all the way to 3840x2160
Adaptive HUD positioning (no more status bar being off to the side)
HUD scaling (HUD scaling for bottomless HUD coming later)
Support for bordered and borderless windowed modes

New gameplay options:

Blitzguards being outfitted with any weapon from the missile/magic weapon arsenal! Yes, that means Blitzguards can use excalibats too!
You can now pick up ammo from dropped missile weapons!
A special respawning enemy game mode called ZomROTT, where you have to gib your enemies to keep them from coming back!
Toggleable Auto Aim
Auto Aim for Missile Weapons
...and more

And all of the improvements made in the icculus source port...

To run the game you'll need the following things:

SDL2.dll (https://www.libsdl.org/download-2.0.php)

SDL2_mixer.dll (https://www.libsdl.org/projects/SDL_mixer/)

And the files:

DEMO1_3.DMO
DEMO2_3.DMO
DEMO3_3.DMO
DEMO4_3.DMO
REMOTE1.RTS

And

DARKWAR.RTC
DARKWAR.RTL
DARKWAR.WAD

HUNTBGIN.RTC
HUNTBGIN.RTL
HUNTBGIN.WAD

Place all those files in the same directory as rott.exe.

BUILDING:

To build the project, you'll need the SDL2.0 development libraries (https://www.libsdl.org/download-2.0.php) as well as the SDL_mixer developement libaries (https://www.libsdl.org/projects/SDL_mixer/, under Binary).

For linux users, just install the following two packages using apt-get

libsdl2-dev
libsdl2-mixer-dev

Before running make on the project, double check the first few lines of the Makefile and make sure you build the right version.

I used MinGW with gcc to build the project.

Custom resolutions

If your preferred screen resolution doesn't show up in the screen resolution menu, launch the game with argument "resolution x", and enter your screen resolution dimensions in the fields marked by *.

Issues with higher resolutions

rottexpr is capable of running at higher resolutions than the original release of RotT, however this comes with a few issues.

Being able to see through walls when up against them/shrooms stretched screen effect. For this issue, visit "ADJUST FOCAL WIDTH" under "VISUAL OPTIONS", and raise the value until the issue disappears.
The game refuses to run at anything higher than 4k. 4k resolution is currently the limit set in code.
