QLL : Level loaders

February 17, 2020 · View on GitHub

What is it?

QLL is a collection of libs aimed to game developers / enthusiasts who want to use existing game files

Game developers who don't want the hassle of creating a new file format for their game levels
People who want to bring existing game levels to new purposes (by creating viewers for example)

We are mainly targeting game levels which formats are well documented and open-source (to prevent us / library users of legal issues with file format)

A word about Licence

Those loaders are published under the WTFPLv2

If you don't understand, think its kind alike public domain / CC0 (basically that means that you can do anything you want)

Loaders

QLL_Q3: Quake3 bsp loader

This loader let you open Quake3 maps (or any game that uses IBSP version 0x02 format) All lumps can be retrived

Example usage:

#define QLL_Q3_IMPLEMENTATION // Do this define only in one CPP file
#include "qll_q3.h"

int main(int argc, char** argv)
{
    // In this example, we consider that a map called "my_map.bsp" is in the application folder
    qll::q3::Q3Level level = new qll::q3::Q3Level("my_map.bsp");
    
    const qll::q3::LevelData level_data = level.getData();
    
    // Example: we fetch entities key/values
    // Each map contained in the vector represents one entity with its key/values (all as string)
    std::vector<std::map<std::string, std::string>> entities = qll::q3::parse_entities(level_data.entities);
    
    // Example game code to load entities
    MyGame::EntityList::loadFromQ3(entities, level_data.models);
    
    // Another example: Extract all level textures names
    for (unsigned int i = 0; i < level_data.textures.size(); ++i)
	{
	    const qll::q3::Texture& texture_raw = level_data.textures[i];
	    MyGame::SomeTextureLoader::loadTexture(texture_raw.name);
    }
    
    // You can fetch many other data (like Models, Brushes, Faces and so on), just take a look at qll::q3::LevelData definition
    // But the data types are very similar to the ones used in http://www.mralligator.com/q3/

    return 0;
}

You can also extend the file to use your own containers / file classes, just take a look at the first #defines
