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. | ||

- Intelligent building placement - Supporting a concept of build order (alternatively, have the build order be complete deduced but that's rather hard) - Intelligent army composition and placement - Scouting Most of the logic needed has a spatial aspect to it. Building placement logic depends on race played. The penalty for expanding building space for zerg is the greatest so there the focus will be on a tight defense/simcity. Terran on the other hand has a higher priority in placing buildings for a smart greater range of vision around the base, although of course balanced with a good simcity to protect key buildings and workers. Intelligent army composition. Here some statistics of the game must be taken in to account, like which unit does what damage to what unit and some soft factors for mobility and build time perhaps. Based on the information that you got, and how much one can afford to keep on going with a certain plan or deviate, build units. Those units must be placed on the map somewhere, which is a separate problem. If you have a logic that gives you the best army composition, then that logic will overlap somewhat in functional appearance as to how to place those units then. Ideally you'd want some soft squishy logic figure everything out, like distance from ramps to make, and if making a concave is smart and such. In terms of an AI class, you can go for that. In terms of making a successful AI, better hardcode this stuff because you ain't gonna peg this one (okay okay, I am making premature assumptions here). Scouting involves spatial discovery with a risk/reward evaluation. Since reward evaluation will be insanely hard (depending also on how the build order is executed as well as decision making for army composition later on) it makes sense to link the amount of risk you're willing to take inversely with the time that the game is playing. BWAPI should, perhaps with a support library, give you a map with the general map structure and starting locations. Luxuries that regular players have as well, which are free for your exploitation. Now if you want to make a very dynamic and soft coded AI bot that does anything good, 11 to 12 weeks isn't going to scratch the surface of that. My approach would be to get the most rudimentary thing running in every department, like what would be needed for the zergling rush and then capitalize on one or perhaps two segments as far as you think you can make it. If you have to write a plan beforehand on what you plan to finish, then that's a bit tough to determine beforehand so I guess better be safe than sorry on your promises. One thing to note, if you start out with the zergling rush, an obvious expansion would be the execution of more complex build orders. Preferably with soft logic in the sense that you can evaluate the benefits of saving up minerals for building a structure sooner rather than later in a point system comparable to the otherwise good sides of having a stronger economy from building more workers, and things like that. I have not played around with BWAPI, I have seen some nice projects coming along for it though. Most of them initially dealt with unit micro, which is another area that can be interesting but most of the benefits came from abusing the insane APM a computer can wrench from the cpu. I'd suggest you contact those who've played with BWAPI before for more info, obviously. | ||

Again, thank you. Awesome post : ) I'll have to post my results on TL (as long as it's not [too much of] a failure :p) | ||

I've got a set amount of data in an excel sheet that I would like to create possibly either a VBA program or C++ program that would as you questions, and then fill out that information accordingly in the spreadsheet in the correct rows. Is this possible? I know that it is possible to create surveys and whatnot with excel, but how can I.."tell the survey to record the results in a spreadsheet?" There will be some other issues as well, say in the program I ask "Is your major math?", select yes, but in that I have to put in the names of the classes I am taking, which means for one row, I would have to have split cells along the way to accomodate them being organized under "math major". I have a feeling if I can get some help in knowing how to create this kind of survey or program to fill information in a spreadsheet. Say my survey goes as this(it's not really going to be used as a survey, but it will act like one, the purpose is the same.). 1. What is your class number? [user enters class number] 2. Are you a Math Major? [User selects yes or no] 3. How many classes are you taking? [number that tells you how many cells to create to fill in each one for each class, this is where the splitting cells in a row and whatnot comes in] 4. What classes are you taking? [User enters data that will fill in the data accordingly] Can anyone show me a demo of this to expand on? | ||

See here for why: http://stackoverflow.com/questions/1039667/why-does-stdfstream-set-the-eof-bit-the-way-it-does http://stackoverflow.com/questions/730910/ifstream-object-eof-not-working Secondly you should probably use: std::vector<BankAccount*> bankAccounts; This will save you a lot of trouble. It uses a dynamic array internally, meaning you can insert any number of elements into the vector (using the push_back member function) and it will resize itself automatically at runtime to fit. In your case, if there is not exactly 10 bank accounts stored inside your file then there will be a problem here. For example, if there are 11 bank accounts in the file then your code will insert the last one into the 11th element of the array, which is undefined behaviour. If there are less than 10 bank accounts stored inside your file, during clean-up you will be deleting a bank account that was never created. You will be calling delete on an uninitialised pointer, which again is undefined behaviour. You could initialise all bankAccount elements to NULL before you read the file, in which case your code would be fine so long as there are always <= 10 bank accounts in your file. Calling the delete operator on a NULL pointer is safe. But again a normal C++ programmer wouldn't do it this way. Infact, a normal C++ wouldn't even use std::vector if they were able. They would rather use something like Boost's ptr_vector for this task, which is a class that owns the pointers internally and handles clean-up for you in its destructor (a popular C++ idiom called RAII, if you're interested). It also provides a nicer interface to your elements than an std::vector of pointers. This is probably not something you should focus on though until you are comfortable with what is actually going on. But just know that it's not always this difficult in C++ once you start using the proper tools for the job at hand  EDIT: How a C++ programmer would write this: http://codepad.org/Qs7nNq3R Also, if you don't want to use stringstream I would recommend sscanf instead of atoi. At least that way you can check for formatting errors properly. atoi simply returns 0 on error, so if 0 is a valid value you won't know if it's a true error or not. However, when you gain more knowledge, you should be aware of the security problems with scanf (namely buffer overflows). Hope this helps Thanks! I'll try to digest some of that... in Java I at least got to use ArrayLists... I guess Vectors are an analog to ArrayLists | ||

Google Docs will display what I want in a spreadsheet, but the format is not of what I need it to be in. What I basically want is a form like google docs that will fill in cells of a preexisting worksheet. | ||

If you use anything that is synchronized, you need to do so with the utmost care or it will come back and bite you at some inopportune time later. Vector, as an example, is prone to deadlock in some rather trivial two-thread use cases in which an unsynchronized ArrayList would perform perfectly. If you do not desperately _need_ a synchronized list, you should always go for an unsynchronized ArrayList. If you do need one that is synchronized, you may want to used a Collections.synchronizedList() although on 1.4.2 that synchronization seems slightly buggy (not sure if it's fixed in 5.0). Vector might be more functional. | ||

It's equivalent to if(1==true) {2} else {3} Correct me if I'm wrong. Its being a while. | ||

Not in C# it isn't! (I think, because 1 doesn't == true in C# if that's what you're refering to). Anyways the numbers were just examples. Now, onwards, to another question! Using C# btw. So I've got a LAMP set up on VMware, which I want my .net app to communicate to, so far so good. Now, my choices are OleDB, ODBC or NET connector, fair enough. I went ahead and picked OleDB because frankly it was the first result in google, and this tutorial I found seems reasonable. So I guess my question is wtf is a connector? Actually that's not really my question it obviously connects MySQL and .NET but is it installed on the server with MySQL or the server with the .NET app? Because I'm only able to find a windows executable for it, surely there must be a linux version if it's supposed to be installed on the MySQL side. Scratch all of that, got it working. Downloaded this https://cherrycitysoftware.com/CCS/Providers/ProvMySQL.aspx on .net application server. | ||

This time, how do I sockets? Relax, I'll go more in depth, here's my current set up: VM Linux with MySQL <- Server application (C#) <- Client application(C#). All well and good, in fact I can register and "log in" based on data from the database. However I'm stuck when it comes to handling multiple user connections. Now, I obviously want threads, but how do I "manage" the connections? I'm thinking I should keep an array of users that connect, then make a separate thread for each user of course, and then dispose of the threads that aren't in use because users disconnected. Makes sense right? But how do I go about doing that? I.E. Do I make one "master socket" that everyone connects to, then make a new thread every time someone connects to it, and somehow automagically transfer that client over to the new socket? All in all I am confuse. | ||
