  • Do you test your SQL/HQL/Criteria ?

    - by 0101
    Do you test your SQL or SQL generated by your database framework? There are frameworks like DbUnit that allow you to create real in-memory database and execute real SQL. But its very hard to use(not developer-friendly so to speak), because you need to first prepare test data(and it should not be shared between tests). P.S. I don't mean mocking database or framework's database methods, but tests that make you 99% sure that your SQL is working even after some hardcore refactoring.

  • In an Entity-Component-System Engine, How do I deal with groups of dependent entities?

    - by John Daniels
    After going over a few game design patterns, I have settle with Entity-Component-System (ES System) for my game engine. I've reading articles (mainly T=Machine) and review some source code and I think I got enough to get started. There is just one basic idea I am struggling with. How do I deal with groups of entities that are dependent on each other? Let me use an example: Assume I am making a standard overhead shooter (think Jamestown) and I want to construct a "boss entity" with multiple distinct but connected parts. The break down might look like something like this: Ship body: Movement, Rendering Cannon: Position (locked relative to the Ship body), Tracking\Fire at hero, Taking Damage until disabled Core: Position (locked relative to the Ship body), Tracking\Fire at hero, Taking Damage until disabled, Disabling (er...destroying) all other entities in the ship group My goal would be something that would be identified (and manipulated) as a distinct game element without having to rewrite subsystem form the ground up every time I want to build a new aggregate Element. How do I implement this kind of design in ES System? Do I implement some kind of parent-child entity relationship (entities can have children)? This seems to contradict the methodology that Entities are just empty container and makes it feel more OOP. Do I implement them as separate entities, with some kind of connecting Component (BossComponent) and related system (BossSubSystem)? I can't help but think that this will be hard to implement since how components communicate seem to be a big bear trap. Do I implement them as one Entity, with a collection of components (ShipComponent, CannonComponents, CoreComponent)? This one seems to veer way of the ES System intent (components here seem too much like heavy weight entities), but I'm know to this so I figured I would put that out there. Do I implement them as something else I have mentioned? I know that this can be implemented very easily in OOP, but my choosing ES over OOP is one that I will stick with. If I need to break with pure ES theory to implement this design I will (not like I haven't had to compromise pure design before), but I would prefer to do that for performance reason rather than start with bad design. For extra credit, think of the same design but, each of the "boss entities" were actually connected to a larger "BigBoss entity" made of a main body, main core and 3 "Boss Entities". This would let me see a solution for at least 3 dimensions (grandparent-parent-child)...which should be more than enough for me. Links to articles or example code would be appreciated. Thanks for your time.

  • Are any Zotac Zboxs suitable as HTPC / media centres?

    - by Jakub
    Are any Zotac Zboxes suitable as HTPC / media centres? I'm after a fanless HTPC client in the living room to work with my MythTV server in my home office. I like the small compact form factor of the Zbox but what little I could find by Googling didn't clearly recommend any particular models for Ubuntu / MythTV / XBMC. Can anyone recommend any models that work with little hassle? Or, if there aren't any, are there other more Linux-friendly small format fanless PCs I should be looking at instead?

  • Are shorter URLS better for SEO?

    - by articlestack
    Many people shorten their URLs. But as per my understanding it creates overhead of extra redirection, other can not guess about the target article with their url, and it should be less friendly for "inurl:..." type search. Should I shorten the URLs of my sites? Is there any advantage with short URLs besides the fact that they take fewer characters in anchor tags on the page (good for site loading)?

  • Should a programmer be indispensable?

    - by Tim
    As a programmer or system administrator, you could either strive to have your fingers in every system or to isolate yourself as much as possible to become an easily-substituted cog. Advantages of the latter include being able to take vacations and not being on call, while the former means that you'd always have something to do and be very difficult to fire. Aiming for either extreme would require a conscious effort. Except for the obvious ethical considerations, what should one strive for?

  • Is there a simple way to stop enemies standing in the same spot?

    - by Iain
    So: top-down game, my enemies chase the player, when they get within a certain distance they stand still and fire. If they're all coming from the same direction they all end up standing in the same spot (i.e. standing "within" each other), as I'm not currently doing collision detection between enemies - they are free to pass over each other. What's a simple way around this? Either some form of collision detection or some ai?
