I am using the Scumm VM codebase as part of a personal code project.
I am trying to make multiple instances of Scumm VM so that multiple games can be managed at once by a website.
Here is a condensed version of how I have gone about it. I have cut a lot of stuff out . . .
CLIScumm::Wrapper::Wrapper(System::String^ gameFolderLocation, CopyRectToScreen^ screenUpdated)
{
g_system = . . .
PluginManager::instance().init(); //TO DO FIX this hack, so that the plugin manager is not inited twice
PluginManager::instance().loadAllPlugins(); // load plugins for cached plugin manager
DetectedGames detectionResults = EngineMan.detectGames(files).listDetectedGames();
Common::String domain = EngineMan.createTargetForGame(detectionResults.front());
//Common::String domain = "kq3";
ConfMan.addGameDomain(domain);
ConfMan.setActiveDomain(domain);
}
void CLIScumm::Wrapper::init()
{
scummvm_main(0, {});
}
There is a new instance of this 'Wrapper' for every instance, and init is called once per instance as well.
This system works for a single instance, but as 'g_system' is a global variable (forgive me if I haven't used the right terminology), it is shared between instances of the wrapper, rendering multiple instances impossible
.Has anyone else had any previous experience in trying to make multiple instances and could they guide me in the right direction?
