Progress

• Game rooms are nearly all added #10
• Data import is 90% finished #5
• The airport is implemented
• The player character is implemented
• All of the gameplay is still missing

Todo

How to compile the Godot branch

• Download Godot 3.2 Mono or later
• Install Airline Tycoon Deluxe and download this repository
• Build the project in godot ("Build" in the top right corner in godot)
• Go to the new Build Manager tab on the upper left corner of godot
• Enter the Airline Tycoon Deluxe path and hit "Extract Images" in the Images tab of the builder interface. Godot will now load all files. This will take a little while. You have to restart godot to see the new files, as godot does not update the explorer

(The game images can't be posted on github due to copyright reasons. Thats why there are files missing inside the project. Opening scenes let's godot know that there are files missing and it will delete all references to those files. If we run the project before godot checks for files, all missing files will be added!)

How to build the project

• Go to the Build Manager tab on the upper left corner of godot
• Go to the Build Management tab.
• Click on Prepare Build. This will empty all of your image files in the Images folder.
• You can now Export the project using the export feature of godot. (Don't forget to re extract all the image files)

All images are work in progress!

openatdeluxe's Issues

Is the project abandoned

Hi,

I see that the latest change dated by 6 months ago. So, my question is reasonable: is the project abandoned?
I would help you, but not sure how. I've never participated in gamedev projects

Increase loading performance

Currently loading a room means blocking the main thread and stopping everything.
That is not really desired behavior.

We should test the performance of multithreaded loading and the InteractiveLoader of Godot.
Or maybe we can just load every room into the game to prevent any mid session loading

Missing Cursor

Moved from #4
The cursor sometimes doesn't show, even though the files are there.

Could be a Z-fighting issue with the CanvasLayer being on Layer 1 - the default layer

Game Export needs special files

The game export, when exporting with godot, needs some more libraries for the text handling/saving. The original files are saved in the 1252 Windows encoding. This encoding needs the I18N.dll and I18N.West.dll. Sadly godot doesn't add them to the exported files, meaning we need to add them manually.

This step should be added to the export procedure where the image file stripping is handled.

License needed

We should decide on a licence for the code.

I would go for the MIT Licence as its already common among open source ports (Like CorsixTH)

Network play

Compiling the GOG source code

@WizzardMaker I'm working on reverse engineering the missing headers for the libraries in the GOG source code. I've already got everything compiling, though to get the static libraries to link I actually have to use Visual Studio C++ 6.0 (yes, the one from the 90s).

Of course just getting everything to compile is the easy part, there are a few crucial bits of header-only code not present in the static libraries that has to be reverse engineered (including the memory layout for each class). I'm making some good progress on that, my latest build can actually get in-game, though it quickly crashes on sprite corruption:

I'll upload the source code to GitHub as soon as I've finished fully reverse engineering and debugging the header-only code. If you have any questions I'd be happy to answer them.

Add some screenshots in the README

I think people will be more interested in testing this re-implementation and maybe collaborate with some code if you show the current state of this port. Even early screenshots are fine!

Crash when starting a free game

Describe the bug
When starting a new game (FREE GAME from the main menu), the game crashes with this error:

Unhandled Exception:
System.NullReferenceException: Object reference not set to an instance of an object.
  at (wrapper managed-to-native) Godot.NativeCalls.godot_icall_2_378(intptr,intptr,intptr,bool)

  at CharacterItem._GuiInput (Godot.InputEvent e) [0x00035] in /home/xerxes/Documents/coding/OpenATDeluxe/src/CharacterItem.cs:32 

To Reproduce

• Select NEW GAME from the main menu

Expected behavior

• The airport scene should load fine

Further reverse engineering

Figure out how

• *.pol
• *.dat
• *.mcf
• *.csv
• *.raw
• *.smk

are structured

Initial File Loading Bugged

The current check, whether we should update all files is bugged. It will try to get a new path and re-import all files on game start, when starting from the standalone export.

There are problems with the saving a version number with the game data as it will ultimately end up in the editor and thus in the exported game.

This is rather low priority, but still needs to be addressed.

Center camera at airport exit elevator on first boot

Transparency issue with the status bar

The status bar has some black pixel, the image extractor makes them transparent.

We should maybe add a black texture behind the status bar to hide possible background overlap

Project death?

Dear WizzardMaker,

it seems that there is no work in progress here. Is your project death or will there be a release soon?

Kind Regards,

Krawei

Sometimes RoomManager can't find the room scenes

Was already mentioned in #4 by @Serphentas

It looks like a Godot bug. Directory.Open(PathName) returns an error 31 (InvalidParameter).
The script works when the base scene is started and not loaded from the load.

Fix would be to change the system from searching for rooms to add them in the editor manually.

Loading and displaying characters in the airport.

Recreate rooms

Get all rooms in a list and set the full background according to the current room

Only includes visual content, no game logic

Image Management System

Initially started by @WizzardMaker

We need a system to easily access all needed files and their textures. A central place where all GFXLibs are loaded and we have a template system with objects/scenes for all files, or maybe use an editor for a level with a saved level file for loading

programming language decision

We have to decide a language for the project when using Godot.
I don't want a mumbo jumbo of 4 different languages having to work together.

We have to decide between:
C# - not yet 100% production ready in Godot, but feature complete and has all the benefits of C# like strong typing, LINQ, easy understanding

C++ - fully supported by godot, Godot enforced overhead for editor variables, standard functions etc. Not as easy to get into learning curve wise for other contributors

GDScript - 100% supported by godot. Unknown language for me and maybe others

Preserve camera position when leaving room

When entering a room from RoomAirport and then leaving it, the camera should return to its former position.

Le projet est il abandonné en 2024 ?

Bonjour, je viens vers vous pour savoir si le projet Airlines Tycoon était abandonné en 2024 ?
Car je vois que depuis quelques années il n'y a plus de contribution malheureusement et j'ai de plus en plus de mal à faire tourner le jeu original sur Steam.
Merci d'avance

File pathing wrong for non windows game versions

Is your feature request related to a problem? Please describe.
Linux and Mac store their files in a different folder structure and also handle the file name capitalization differently.

Describe the solution/addition you'd like
Custom helper class for File handling would be needed. It will search for the needed file in the game folder. This will prevent errors about missing files (except when they are not in the game folder to begin with) and wrong file name capitalization.
This could fix #16 and #21
