    Leadwerks Community GameLib

    in Programming

    Posted

    The missing classname key is a bit problematic in 2.3, since you have to take some random other key to identify the class. You could also set some custom entity key with Notepad++ in the sbx file, for example class_name="light_directional", but of course it would be nicer to have that functionality in Editor.

     

    It could be also fixed with a complete new LUA script set for all default entities of LE, so that each LUA script provides a classname field where the user can enter the class name. Maybe I will do that for gamelib, and include modified versions of all lights and other default entities with gamelib.

    Framework ? not Framewerk?

    The benefit is not exactly nothing, since BlitzMax users also need sometimes to use other languages. Most commercial games are using several 3rd party libraries, and you don't find them for BlitzMax. For example Far Cry 2 had a huge list of 3rd party libraries. If any of such 3rd party libraries then need to access LE, Lua or framework, you will need to use engine.dll. Also the upcoming DLL version of GameLib will have the same need.

    Because it's part of the engine now, not a seperate product. You don't put the company "logo" more than once into a product, so Leadwerks Engine covers already that :) It's also less visible now, since all framework commands appear like plain commands and not using any visible reference to framework (except for a few, and in Lua).

    Putting additional game core related entities to a Editor scene is also not the optimal solution. Then all those additional entities would be needed to be present in all scenes. That's redundant and allows unique information to be corrupted (as the same information should be present in all scenes).

    Of course this problem is raised by Editor itself, since it doesn't utilize a "common scene" and the "actual scene" concept. The "common scene" would contain all entities which are common in all scenes (for a specific project).

    However, there is a indirect solution for this problem: You could have a "common scene reference" entity, which would then load the common scene, and all its contained entities.

     

    Another solution would be to rewrite Editor to use sqlite databases instead of sbx files :(

    Let's start improving this with the options like screen resolution and which map to load.

    The first thing which comes to my mind would be reading a fpscontroller2.ini file from disk with LUA.

    Then there could be a fpscontroller2config.lua which would launch an UI where the user can select the options.

    It could be also part of fpscontroller2.lua, but then there would need to be a title screen where you can choose to play the game or to configure the settings.

     

    I'm not sure how your GAME_MODE idea works, because then it should support all kind of game types. I think it's easier to make a seperate lua file for each game type (at least in the beginning).

    Yeah, I though also of making fpscontroller using some classes, but this is just the first working version with Engine.exe.

    I noticed that emitters don't work, and that the skybox is loaded although it should not. Must be a bug in Engine.exe :lol:

    You can use this fpscontroller2.lua from Editor or by dragging it over Engine.exe.

    I think it's good to learn C++, because then you can do anything, and you can use it at the office too. Just don't make the mistake and learn old C++ (with pointers and new/delete operators), but learn the new C++ with references (instead of pointers) and STL (to replace pointers and new/delete needs) and Boost libraries.
