EDIT: ISSUE FIXED
We were instanciating things in static wich were called before the resources could be loaded
Hello, me and a friend are trying to recreate a game we made in C sometime ago. However we are stuck at the resource loading.
We have tried many different things and it always crashes. The issue seems that the resources are lost when the end of the scope is reached but we can't figure out why. We are new to c++ so we are really getting a hard time with that.
We are both compiling on linux (me on Fedora and him on ubuntu).
We have a main Game class in wich everything is stored like the renderer class, the scenes etc and the resource manager is a currently a singleton but we had tried earlier with a static manager with no success.
The thing is that we are getting inconsistent results, depending on wich machine the resources do load fine, and sometimes it crashes with this error:
RPG_MASTERCLASS: src/class/AssetManager.cpp:91: sf::Font& AssetManager::getFont(FontID): Assertion `found != m_fonts.end()' failed.

Usage exemple:
Level::Level()
{
m_index = 0;
m_hasFocus = false;
m_buttons.push_back(Button(Vector2f(250, 100), Vector2f(SCREEN_SIZE.x * 0.1,
SCREEN_SIZE.y * 0.95), AssetManager::getInstance().getTexture(B_EXT_TEX), &buttonBackMainMenuFunc));
m_levelTitle.setFont(AssetManager::getInstance().getFont(INGAME_FONT));
m_levelTitle.setCharacterSize(100);
m_levelTitle.setString("Level " + to_string(m_index));
m_levelTitle.setOrigin(getCenter(m_levelTitle));
m_levelTitle.setPosition(Vector2f(SCREEN_SIZE.x / 2, SCREEN_SIZE.y / 2));
for (int i = 0; i < 100; i++)
addEntity(Vector2f(randomNumber(-1920, 1920 * 2), randomNumber(-1080, 1080 * 2)));
}
We have already watched a few tutorials and exemples of how to implement a resource manager but we always end up with the same problems.
Any help would be much appreciated.
