Expected:
Lines on the arrow indicating your position appear like lines - ie consecutive rows of pixels of same colour that create an illusion of looking at lines.

Actual:
It looks as if parts of the line were "erased".

Tested on Archlinux. Built at b5f1b50

There's far too much C string handling going on. Upgrading to a more robust OOP usage will improve stability and reduce the code.

Eureka is hard coded to highlight the sector tag in Doom Format, but in ZDoom in Hexen format, the action structure was shuffled to use 5 parameters. The Teleport Destination tag can be any one of the 5 parameters. It can also be a ThingID or lineID, depending on the action that triggered it. Eureka should know how to display the Destination for each particular action.

https://zdoom.org/wiki/Category:Teleport_specials

77:TeleportGroup (tid, source, destination, movesource, fog)
215:Teleport_Line (thisid, destid, flip)
71:Teleport_NoFog (tid, useangle, tag, keepheight)
154:Teleport_NoStop (tid, sectortag, nofog)
76:TeleportOther (tid, destination_tid, fog)
78:TeleportInSector (tag, source_tid, dest_tid, fog, group_tid)
39:Teleport_ZombieChanger (tid, tag)

Users need to know what kinds of files they may load.

Here is the error when I try to build this on Linux:

It seems no logo is visible now in About. Instead it's just text.

Stuff needed to do:

• Prepare CMake for macOS with guaranteed FLTK download
• Make sure it can produce signed releases
• Make sure the deployment target is as before
• Make sure the same warnings are shown as on the manual Xcode project, or more.
• Remove Xcode project
• Make sure it still works on Linux

First to change: fopen.

The name may not fit each button.

Would like to see sector tags labelled in 2D view. Bonus if sector hover displays lines to associated linedefs.

In order to make development safe and also to catch any still-ongoing bugs or wrong behaviour, let's write tests for as much of Eureka as possible before continuing feature development.

Expected:
When you press the t key and then click a thing, then try to place it - it places that thing you chose.

Actual:
The first thing placed is always a health bonus. It has to be then changed to the actual thing you meant to place in first place.

Not a big deal and one can get used to it but it's somewhat counter-intuitive. Tested on Archlinux, built from b5f1b50

Things to do:

1. Multiple window interface, one per wad (with option to duplicate windows for wad)
2. Strict wad set per window
3. Optional view of IWAD level (also in another window) with read-only mode by default
4. Intuitive, conventional warnings when exiting "dirty" documents

I started a project in Doom format, made many maps in a single wad. Switched to Hexen format (hit a voodoo doll snag, solved with scripting). It only changed the format for that individual map. All other maps were still in Doom format. Manually iterated through each map, changed format, saved map. Would like a blanket option or rename "Manage project" to "Manage map".

It seems to always require Hexen format and says that "adding SCRIPTS lump" is only available for it, which is nonsense if user opts for another lump.

Alternatively delete it if it's the job of SLADE.

I need a programmatic build system like CMake or others if I want to effectively create multiple unit test programs which don't link to the entire Eureka. This task is to see whether Meson makes a better option than CMake.

Need continuous integration for rarely used platforms.

I cloned the git repo and after checking to make sure I had all the required packages I ran make and got this error:

Anyone know what's going on? I'm running void linux btw.

If not even integrate the nodebuilder into the same executable, to simplify stuff and reduce interprocess point of failure.

May be needed for linedefs as well as sectors.

Steps to reproduce the crash:

1. Load or create a new map
2. press l for linedef (or e w)
3. hover with the mouse over a wall (don't click)
4. hold down the r key and move the mouse, keep moving your mouse cursor outside the boundaries of the wall rectangle (no crash)
5. click once on the wall so that the lines turn from yellow to orange around the rectangle
6. press and hold r and move around the mouse cursor again - as soon as you move the mouse cursor outside of the rectangle - Eureka will crash

Specifically, the enter/exit and hit ceiling/floor sector actors for Zdoom.

https://zdoom.org/wiki/Classes:SectorAction

The following thing actor flags map to these events:

AMBUSH → monsters can trigger the special.
DORMANT → projectiles can trigger the special.
FRIENDLY → players cannot trigger the special.
STANDSTILL → the special will be triggered only once.

Only the first 2 are listed in the UI.

Expected:
Going to File -> Fresh map should bring up a dialog box which should allow creating another map in the wad.

Actual:
A dialog does open but it only has one input box. Changing the text string in it and pressing enter doesn't do anything.
There's no "OK" button anywhere on the interface.

New-map-related options behave very similarly (dialog only has a text input box) so perhaps the other options are affected the same way:

• Fresh Map (already mentioned)
• Copy Map
• Rename Map

Everything else in the editor seems to be working fine.

Using Eureka 1.27b
Tested it on Archlinux with the rapoison window manager.

A workaround I'm using is creating new map lumps in another program and then editing the new maps in the wad in Eureka (it works) but that's not very convenient.

It doesn't seem to output any errors to STDOUT or STDERR when this happens.

Possible solutions:

• I could maybe try an older version and try to pinpoint which commit introduced this problem
• the editor works fine other than this and so does every dialog box in it but there's an off chance that the ratpoison window manager is somehow doing this so I could try it on a different WM

May be related to #28

Expected:
You make a modification. You press Ctrl+T. It asks you if you want to save changes before previewing the map in the game. You click "Save" .....and then the editor either just saves and that's it, or it saves and the game runs the saved wad/map with the modifications you just made.

Actual:
You make a modification. You press Ctrl+T. It asks you if you want to save changes before previewing the map in the game. You click "Save" ....nothing happens

You have to press Ctrl+S and press Ctrl+T and then it previews it as expected.

Tested on Archlinux b5f1b50

Also, just for macOS, give it the standard shortcut (cmd-,)

We need CMake if we want to easily integrate Google Test and make multiple small programs. Start with Linux.

Why not use them?
To do:

• Integrate Google Test into CMake
• Possibly get rid of the submodule
• Update the GitHub Actions to run the tests

Would like to see separate modes for invisible, mapped, and secret tagged linedefs. Useful for optimizing in-game map display.

Built from b5f1b50, tested on Archlinux.

Expected:
Flats and textures shown in the editor sidebar as they would appear in the game/3d view/2d view (without lighting).

Actual:

At least two cases identified so far:

1. Invalid resource files (other than ugh)
2. Ugh files with syntax errors

Instead of suddenly terminating Eureka, they should calmly inform the user and (depending on user experience) either request correction or skip them and close the dialog anyway.

Blocked by

• #23 because we need a more robust wad system.
• #97 because we need to easily handle lifetimes of failed objects
• Scenario: create new project, prepare to overwrite another file. Give it a junk resource file. The operation will fail, but the old file will still be forever lost.

Example:
arg1 (lo-tag): 0
arg2 (type): 1
arg3 (flag): 0
arg4 (opacity): 255
arg5 (hi-tag): 3

sector tag: 768 (3 (hi-tag)*256 + 0(lo-tag))

3D floor will not render.

If lo-tag = 1 and sector tag= 769, 3D floor renders.

Apparently, under Linux, if global::install_dir isn't set from the command-line, it will look in the following list of potential prefixes:

			"/usr/local",
			"/usr",
			"/opt",
			NULL

This suggests it may fail if Eureka was formally installed to another location. We need to test how it behaves and fix it if needed.

Right now it's just a hidden user command

Expected:
When I do git pull and then make -C build only the parts that changed get compiled (usually very quick with other projects I do this with)

Actual:
Everything seems to be rebuilt as a whole from scratch every time - even when the change is minor. It takes a good few minutes to compile everything.

Tested on Archlinux 95fae49

I may be doing something wrong. Do I need to pass some argument to only build parts that changed?

Expected:
Going to File->Delete Map and pressing Cancel on the question should just bring me back to the map I was editing.

Actual:
Pressing File->Delete Map->Cancel deletes the map anyway. (deleted map no longer accessible from "Open Map", next one is opened)

Accidentally lost a whole map I was working because of this. (not a big deal as I can make it anew but not super convenient)

Tested it on Archlinux, Eureka built from b5f1b50

When compiling Eureka, I get an error, as shown in the attached photo. Can this compilation error be fixed, if possible? I am compiling on Arch Linux.

Eureka should be able to read both DEHACKED lumps and .deh files loaded as project resources to get any new things for the level.

It looks unprofessional.

One last (and big) step.

• Make sure it downloads all dependencies
• Make sure it still works on macOS
• Make sure it still works on Linux
• Remove the Visual Studio project

Expected:
Placing a new vertex should make the texture in 2d view adjust to the new shape of the sector.

Actual:
The texture seems to look as if nothing was changed.

Steps:
Create a new wad archive.
Press v for vertices.
Place a point inside the rectangle.

There's no need to keep file handles open and connection to the hard drive, because wads can generally fit in RAM
