Thread Rules 1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution. 2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20) 3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible. 4. Use [code] tags to format code blocks. | ||

I was wondering if anyone knew any good 2D engines that support isometric view and mouse interaction. Thanks in advance. | ||

I have only use the C++ editions of VS so I am not sure how much visibility the C# version provides as far as C++ code and disassembly goes. Sorry if this was unclear. I'm writing both the DLL and the c# code. | ||

not the "does this compile" or "what does this print" type, but as theoretical as possible | ||

I’ve already created earlier versions, so I’m familiar with the programming required, but I have some specific questions about coding. The GUI is written in c#, which calls c++ DLLs to do the real thinking. Both are written by me in visual studio 2010 Express. 1) My board representations make heavy use of bitwise operators. Are these optimized and fast in a managed language? (Specifically Visual c++) 2) How does one debug a DLL? I saw something about attaching a debugger to the DLL. I’m not quite sure how this would work, and the internet says this can’t be done in Express edition anyways. Because I'm not a computer scientist/engineer and just program for fun, I've always used the easiest programming tools, so I sometimes end up learning things backwards. Thanks for the help. You need the .pdb file to be in the same directory as the dll if you want to step in to the library. You can check to make sure visual studio debugger has the symbols loaded if you: - start debug session - In the visual studio toolbar go to debug -> windows -> modules That will give you a list of all the debug symbols it could and could not find. If your library symbols were found, you should be able to set a breakpoint in there and hit it. I am using visual studio ultimate, not sure if you can do it in express Edit: just checked visual studio express 2012 edition, doesn't seem to have a modules option in the debug -> windows menu but that doesn't necessarily mean throwing the .pdb files in the main bin folder won't work. quick google of it gave this link, not sure if it's useful - don't really have time to check it thoroughly http://through-the-interface.typepad.com/through_the_interface/2006/07/debugging | ||

We finally have a good idea, and I want to start off on the best foot possible. I just graduated with a BS in Computer Science, so I'm pretty good at programming. I'm most confident in Java, but I also know a good deal of C#. My friends have no programming experience, and have just started learning Java. I was wondering if anyone knew any good 2D engines that support isometric view and mouse interaction. Thanks in advance. The biggest problem you will find is assets, and there are basically no assets for isometric games, you will have to do them yourself, in fact you are better off doing a full 3d game if you are doing isometric. Regular tiled 2d you should have no problems with however. I haven't seen any good 2d isometric engines, let alone in Java. Probably the best one out there is the one done in Actionscript, but ewww actionscript. I will look for my isometric renderer that I did in Jogl/Java about 4 years ago it should help you. I actually had a basic autotiling engine at some point but lost it when my hd died, this was before I hosted everything in the cloud. An earlier version exists somewhere though I will look for it later. | ||

As for books, I recommend Introduction to Theory of Computation by Sipser. Whether its low level or high level programming isn't important, computing theory is equally deep in both aspects. Look at functional programming and aspects like lambda calculus, which is as far from "coding to the metal" as you can be, while being as deep if not deeper than low level programming. Hell you will spend far more time trying to learn Haskell than C. The term you are looking for is computer science. If you want to go down that path that's a good thing, but you won't learn anything by going through books based on languages. If you want to learn "Java based" computer science, you should study heavily in books on Object Oriented Programming and Responsibility Driven Design. There are also Java specific design patterns (which imo are terrible ideas conjured up in by an academic who only sees things in a vacuum), such as coding and designing with interfaces rather than concrete classes. | ||

I'm currently doing XNA tutorials, specifically because I had so much trouble finding an engine in Java. I think all I really need is tiling, collision detection, and a way to do menus. | ||

Knowledge was never a problem, discipline was, it would be 1 year down the track and I'd find a new way to do things, a new renderer, new language, and repeat the cycle again. Netgore is a 2d engine that was done in XNA I think, it took 2 years and the renderer was converted to SFML. Also layering in iso will cause you a lot of trouble if you are going to do anything slightly complex, and that is just the tip of the iceberg  http://projectzomboid.com/blog/2011/04/isometric-development/ | ||

Create a simple diagram with the classes you think you need, with their operations. Don't code until you've made fairly complete diagram. Extra: you always use the first element of 'index', and you overwrite the first element of 'Portfolio'. | ||
