RPG Paper Maker

Overview

RPG Paper Maker is a game making engine, free for non commercial use, allowing you to create a 3D universe with many 2D sprites and even 3D objects using a simple interface for all available platforms: Windows, Linux, and MacOS.

📂 Project organization

The organization contains some independent repositories. If you want to fork several repositories, you should put them all in the same parent root. Example:

--- RPM                    <- A parent folder containing all your repos
    |--- RPG-Paper-Maker   <- The engine repo that will use infos from your local Game-Scripts repo
    |--- Game-Scripts      <- The repo editing game scripts
    |--- ... (other repos)

RPG-Paper-Maker is the game editor software (RPG Paper Maker). It is entirely written in C++ and is managing all the json files linked to a project such as maps, statistics...
Game-Scripts is all the stuff needed for building a game (mainly Javascript scripts). We are using the executable and scripts in order to create a fresh new project in the software. This program is using QML and Javascript. It is also interpreting all the json files that are generated by the RPG Paper Maker engine.
Game-documentation contains all the stuff for generating javascript game documentation for users.
Basic-Ressources contains all the basic ressources that the users can use for there projects (pictures, musics...).
Updater is the updater that installs and check for RPG Paper Maker updates.

How to build the project

Install Qt on your OS with the Open Source installation. During the installation, you should select the most recent Qt version (/!\ Linux users should use Qt5.8 for having musics working). We recommend you to use the QtCreator IDE too. You should also install gcc compiler if it is not already done.
Clone and go to this repo
Update the modules with the command:

Linux:

./update-mods

Windows:

./update-mods.bat

NOTE: You should run this script when you want to update the recent dev changes for Basic Ressources and Game Scripts. This will first search your local changes, and then module github repo if you didn't clone it.

Open QtCreator
Open the RPG-Paper-Maker.pro file.
Run qmake (right click on project root).
Select the project to run (EditorApp or Test) in the bottom-left configuration pop-up
Build and run the project

If you are having any error that means that you are missing a package. Check the error and try to find out what's missing. Please report any kind of error at Wanok.rpm@gmail.com to help other contributors.

RPM Singleton

RPM singleton is used for storing constants such as fix paths, integer values, etc. It also stores pointers to the current opened project and engine settings in order to have an access to it at any time in the program. Common functions are also available. For example, a function to write a Serializable class in a .json file is available.

✨ UI design

We are using the Qt creator designer for generating XML files for all the widgets. These files have a .ui extension.

SuperListItem

The SuperListItem class is used for being displayed with PanelSuperList or WidgetSuperTree, and stored easily in .json files. It has at least an ID and a name. For example, a monster in a game is a SuperListItem (SystemMonster class).

A list of SuperListItem will be stored in a QStandardItemModel model class. Here is a common way to add a SuperListItem to a model list:

    QStandardItem * item = new QStandardItem();
    SuperListItem* super = new SuperListItem(i, "My item"); // COuld be SystemItem class for example
    item->setData(QVariant::fromValue(reinterpret_cast<quintptr>(super)));
    item->setFlags(item->flags() ^ (Qt::ItemIsDropEnabled));
    item->setText(super->toString());
    model->invisibleRootItem()->appendRow(item);
