If you're looking for more inspiration for ideas, beware of our [[TODO]] (and the other TODO lists linked from there) and our [[OpenTasks]] pages. Many of the tasks listed there might be incomplete or outdated, or too difficult for a new developer. The best thing to do is to come and talk to us!

== GUI Tasks ==
Our current GUI could use refreshing and updating, in particular to improve how
it works with newer platforms such as iOS or Android. We have a few suggested
tasks:
=== Improve touchscreen GUI <span style="color:red">(To be confirmed)</span>===
Technical contacts: [[User:Sev|sev]].
Difficulty level: Easy (code) / medium (architecture). You'll need a touchscreen device which can run ScummVM, to test on.
Our launcher/options GUI has been designed for keyboard/mouse input, and does
not work well in practice on modern touchscreen devices.
Since it is theme based, part of the problem can be resolved by using a custom
theme. However, our GUI code will need extensions to allow it to behave like a
proper touchscreen application. See [[OpenTasks/Generic/Touch GUI]] for more details.
=== Improve Main GUI <span style="color:red">(To be confirmed)</span>===
Technical contacts: [[User:Sev|sev]].
Difficulty level: Easy.
We have a wishlist for improved GUI widgets; we'd like better sliders, multiline text widgets, an improved list widget, and better widgets for PopUps.
Also, several years ago, we switched to a new XML-based and vector-based GUI, but unfortunately during this transition number of nice touches were lost. In particular, the current GUI lacks soft shadows and antialiasing in number of places. We'd like them back! At the same time, it would be nice to add support for transparent PNG files.
Finally, it would be nice to have support for a scalable GUI which looks good at modern resolutions, which would require changes to our theme format, among other improvements.
See [[OpenTasks/Generic/Improve GUI Look]] for more details.

Many 90s-era adventure games were developed using the Macromedia (now Adobe) Director tool. It would be nice to be able to play these games in ScummVM! We have a WIP engine in ScummVM tree, but it requires much more work in order to implement all hundreds of Lingo commands.

Maupiti Island is the sequel of Mortevielle Manor, both released by Lankhor. Both games were best sellers at the time and were games of the year in France. Nevertheless, best sellers of the time were still selling low volumes and Maupiti Island is nowadays pretty rare ans unknown.

The original DOS sources of Maupiti Island have been secured recently. They are written using a mix of Pascal and assembly. The blitting part of the game shares a lot with Mortevielle Manor and the speech synthesis is not in the scope of the task, so it may not be required to reimplement this assembly code.
Partial Pascal sources of Maupiti Island (Atari ST) have been secured recently. Some utility functions are missing, which were written using a mix of Pascal and assembly. So, the whole harcoded logic is available with most of the utility functions. Some reverse engineering may be required if the equivalent functions in Mortevielle are not working out of the box for the DOS version.


The purpose of this task is to reimplement a Maupiti Island engine for the DOS variants of the game in at least two languages, using Mortevielle Manor and the original sources as documentation.

We got hold of the original source code written in C with some x86 assembler and Mission Supernova was ported to ScummVM and translated to English as part of GSoC 2017. We now need to rewrite the second game as well in a portable C++ and polish its English translation.

=== The Immortal ===
Technical contacts [[User:dreammaster|dreammaster]] or [[User:Strangerke|Strangerke]]
Difficulty level: Hard. Good knowledge of C++ and assembly (x86 or 68K or 6502) is required.
The immortal was released in 1990 by Electronic Arts. It's a mix of genres involving RPG elements with action and puzzles.
The gameplay is different one variant to the other, and all variants are written in assembly, making it more difficult to support all the variants.
In 2018, a GSoC student picked this task but, due to personal issues, didn't manage to complete the task. The purpose of the task is therefore to implement an engine for a variant of the game, using the original sources and the work of JoeFish as a documentation.

Our current Android port is in need of improvement, especially combined with modern versions of Android. We'd like to improve the GUI and the input code in particular, but hopefully you also have your own ideas if you've tried the port (if you haven't: do so!). There are some patches already available, and it should be possible to merge code from other projects (such as SDL 2). A native configuration GUI could also be an option.

ScummVM offers 8 freeware games for download, but they need to be downloaded and installed manually. It would be great to develop a universal system which would let us descibe a game, e.g. provide screenshots, game descriptions, metadata, and package it for different platforms, so we could put them to different applicaiton distribution systems.

=== Text to speech <span style="color:red">(To be confirmed)</span>===

We have two suggested tasks in the direction of text-to-speech:
'''Adding text-to-speech support in Mortville Manor'''
Difficulty: Easy (depending on how you want to approach the task); just knowledge of C++ and some experience programming should suffice.
The original [[Mortville Manor]] game used a speech synthesis system based on PC Speaker.
Our hope for this task would be to replace this obsolete speech synthesis with an external dependency which would allow the implementation of modern text-to-speech generation, in (at least) French, German and English. We have some ideas for which libraries would be suitable, but we're also open to suggestions (and offering the option of platform-specific APIs is also a possibility).
'''Adding speech synthesis of on-screen text for people with reduced sight or for learning to read'''
Difficulty: Medium. You'll need to be comfortable enough with C++ to be able to (quickly) understand enough of the existing engine code in order to add this functionality.
Using the same library used in the previous task, it would be nice to have similar text-to-speech generation for other games. The challenge here would (hopefully) be to add the necessary interfaces for providing the text, and any needed other information (such as timing), to individual game engines. Part of your preparatory work would be working out (with our help) which engines to target.
This task would allow people suffering from sight issues to play more games in ScummVM, and it could also be very useful to help people who are learning to read.
Alternatively (or additionally), you could consider adding other accessibility features.
