  • What are the pro/cons of Unity3D as a choice to make games?

    - by jokoon
    We are doing our school project with Unity3d, since they were using Shiva the previous year (which seems horrible to me), and I wanted to know your point of view for this tool. Pros: multi platform, I even heard Google is going to implement it in Chrome everything you need is here scripting languages makes it a good choice for people who are not programming gurus Cons: multiplayer ? proprietary, you are totally dependent of unity and its limit and can't extend it it's less "making a game from scratch" C++ would have been a cool thing I really think this kind of tool is interesting, but is it worth it to use at school for a project that involves more than 3 programming persons ? What do we really learn in term of programming from using this kind of tool (I'm ok with python and js, but I hate C#) ? We could have use Ogre instead, even if we were learning direct x starting january...

  • SQL Server 2008 Dead lock issue

    - by user173552
    I got into a deadlock issue where I am struggling find the root-cause...The Deadlock graph suggests that an UPDATE statement became the victim over a SELECT statement... What puzzles me is that the UPDATE statement is trying to acquire an index on some other table that is never referred in update statement... This is how my UPDATE statement looks like... UPDATE Table set col1 = @P1 where col2 = @P2 This statement acquired a X lock on the col2 index, but also tries to acquire an index on a column defined in some other table that is no way related to the UPDATE statement... And the SELECT statement that won the deadlock situation had nothing to do with the table or index in the update statement but tried to acquire an index on the table in UPDATE statement. eventually causing the DEADLOCK.

  • MySQL/SQL: Update with correlated subquery from the updated table itself

    - by Roee Adler
    I have a generic question that I will try to explain using an example. Say I have a table with the fields: "id", "name", "category", "appearances" and "ratio" The idea is that I have several items, each related to a single category and "appears" several times. The ratio field should include the percentage of each item's appearances out of the total number of appearances of items in the category. In pseudo-code what I need is the following: For each category find the total sum of appearances for items related to it. For example it can be done with (select sum("appearances") from table group by category) For each item set the ratio value as the item's appearances divided by the sum found for the category above Now I'm trying to achieve this with a single update query, but can't seem to do it. What I thought I should do is: update Table T set T.ratio = T.appearances / ( select sum(S.appearances) from Table S where S.id = T.id ) But MySQL does not accept the alias T in the update column, and I did not find other ways of achieving this. Any ideas?

  • Which SQL query is faster? Filter on Join criteria or Where clause?

    - by Jon Erickson
    Compare these 2 queries. Is it faster to put the filter on the join criteria or in the were clause. I have always felt that it is faster on the join criteria because it reduces the result set at the soonest possible moment, but I don't know for sure. I'm going to build some tests to see, but I also wanted to get opinions on which would is clearer to read as well. Query 1 SELECT * FROM TableA a INNER JOIN TableXRef x ON a.ID = x.TableAID INNER JOIN TableB b ON x.TableBID = b.ID WHERE a.ID = 1 /* <-- Filter here? */ Query 2 SELECT * FROM TableA a INNER JOIN TableXRef x ON a.ID = x.TableAID AND a.ID = 1 /* <-- Or filter here? */ INNER JOIN TableB b ON x.TableBID = b.ID

  • LINQ query needs either ascending or descending in the same query

    - by Sir Psycho
    Is there anyway this code can be refactored? The only difference is the order by part. Idealy I'd like to use a delegate/lamda expression so the code is reusable but I don't know how to conditionally add and remove the query operators OrderBy and OrderByDescending var linq = new NorthwindDataContext(); var query1 = linq.Customers .Where(c => c.ContactName.StartsWith("a")) .SelectMany(cus=>cus.Orders) .OrderBy(ord => ord.OrderDate) .Select(ord => ord.CustomerID); var query2 = linq.Customers .Where(c => c.ContactName.StartsWith("a")) .SelectMany(cus => cus.Orders) .OrderByDescending(ord => ord.OrderDate) .Select(ord => ord.CustomerID);

  • MySQL INSERT data does not get stored in proper db, only temporary?

    - by greye
    I'm having trouble with MySQL or Python and can't seem to isolate the problem. INSERTs only seem to last the run of the script and are not stored in the database. I have this script: import MySQLdb db = MySQLdb.connect(host="localhost", user="user", passwd="password", db="example") dbcursor = db.cursor() dbcursor.execute("select * from tablename") temp = dbcursor.fetchall() print 'before: '+str(temp) dbcursor.execute('INSERT INTO tablename (data1, data2, data3) VALUES ("1", "a", "b")') dbcursor.execute("select * from tablename") temp = dbcursor.fetchall() print 'after: '+str(temp) The first time I run it I get the expected output: >>> before: () after: ((1L, 'a', 'b'),) The problem is that if I run it again, the before comes out empty when it should already have the entry in it and the after doesn't break (data 1 is primary key). >>> before: () after: ((1L, 'a', 'b'),) >>> before: () after: ((1L, 'a', 'b'),) >>> before: () after: ((1L, 'a', 'b'),) If I try running the insert command twice in the same script it will break ("Duplicate entry for PRIMARY KEY") Any idea what might be happening here?

  • How to check value of stored procedure output parameter

    - by Anna T
    I have a stored procedure that: A. inserts some rows into a "table variable" based on some joins B. selects all values from column x from that table into a string with comma separated values C. selects all from the "table variable" If I execute the procedure like this: EXEC CatalogGetFilmDetails2 2,111111; a table is returned as instructed per step C above. How can I execute it so that also the output parameter value is displayed? (see point B above). I need to check if it's calculated properly. And since the second parameter is of output type, meaning it's calculated inside the procedure, why is it mandatory to specify a value for it when executing the procedure? I normally use a random value for it, it anyway doesn't matter/impact the result. On the other hand if I try to execute it without the output parameter, it returns an error) Thank you very much! This is how the procedure starts: CREATE PROCEDURE CatalogGetFilmDetails2 (@FilmID int, @CommaSepString VARCHAR(50) OUTPUT) AS And this is how @CommaSepString is calculated: SELECT @CommaSepString = STUFF((SELECT ', ' + Categ FROM @Filme1 FOR XML PATH('')), 1,1,'')

  • Implementation of a Rules Engine in Your Business Applicaitons

    - by enonu
    I'm for an experience driven answer from a few software engineers who have implemented a rules engine in their internal business applications. How has it affected your business in the following ways: Ability to launch and iterate over business driven logic Ability to have "business users" perform the actual modification of those rules rather than developers. Ability to comprehend the business rules in general. Quality of the software releases. More or less bugs from the end-user's POV? Speed of the applications. If you had to do it all over again, what would you do differently? Lastly, I'm looking for a qualification of your answer w/ respect to the architecture. Would you do the same thing if you were deploying to a 1-machine setup vs. your architecture vs. a multi-tier cloud-based distributed architecture using 1000s of machines? How would it be different? Thanks!

  • JavaScript function pass-through?

    - by Lance May
    I'm not sure if this is doable, but I would like to be able to set a jQuery UI event as a function (directly), as opposed to continuing to wrap in additional function(event, ui) { ... } wrappers. Hopefully you can see what I'm going for from the example below. Here is what I would like: $("#auto").autocomplete({ source: "somepage.php", select: dropdownSelect, minLength: 0 }); Now I would think that the above would work, since I'm simply trying to say "continue firing this event, just over to that function". Unfortunately, that will not work, and I'm ending up with this: (and for some reason, a disconnect from all data) $("#auto").autocomplete({ source: "somepage.php", select: function(event, ui) { dropdownSelect(event, ui) }, minLength: 0 }); Thanks much in advance.

  • Why am I am unable to open exe files?

    - by Aaron
    It doesn't matter what disk I use, it can not open the program. I keep getting the following error: Archive: /media/xxxxxxxx/INSTALL/_Setupa.exe [/media/xxxxxxxxxx/INSTALL/_Setupa.exe] End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. zipinfo: cannot find zipfile directory in one of /media/xxxxxx/INSTALL/_Setupa.exe or /media/xxxxxxxxx/INSTALL/_Setupa.exe.zip, and cannot find /media/xxxxxxxxx/INSTALL/_Setupa.exe.ZIP, period. Any ideas?

  • Advanced MySQL Search Help

    - by Brandon
    I've been trying to come up with something for a while now to no avail. My MySQL knowledge is rudimentary at best so I could use some guidance on what I should use for the following: I have 2 tables ('bible' and 'books') that I need to search from. Right now I am just searching 'bible' with the following query: SELECT * FROM bible WHERE text LIKE '%" . $query . "%' ORDER BY likes DESC LIMIT $start, 10 Now, I need to add another part that searches for some pretty advanced stuff. Here is what I want to do in pseudocode which I am aware doesn't work: SELECT * FROM bible WHERE books.book+' '+bible.chapter+':'+bible.verse = '$query' $query would equal something like Genesis 1:2, Genesis coming from books.book, 1 coming from bible.chapter and 2 coming from bible.verse Any help/guidance on this is much appreciated =)

  • When does a query/subquery return a NULL and when no value at all?

    - by AspOnMyNet
    a) If a query/subquery doesn’t find any matching rows, then it either returns NULL or no value at all, thus not even a NULL value. Based on what criteria does a query/subquery return a NULL and when doesn’t it return any results, not even a NULL value? b) I assume a scalar subquery will always return NULL, when no matching rows are found? I assume most-outer scalar query also returns NULL if no rows are found? c) SELECT FirstName, LastName, YEAR(BirthDate) FROM Persons WHERE YEAR(BirthDate) IN (SELECT YearReleased FROM Albums); If subquery finds no results, is then a WHERE clause of an outer query translated into WHERE YEAR(BirthDate) IN (null); ? If instead WHERE clause is translated into WHERE YEAR(BirthDate) IN(); then shouldn’t that be an error condition, since how can YEAR(BirthDate) value be compared to nothing? thanx

  • SQL Server indexed view matching of views with joins not working

    - by usr
    Does anyone have experience of when SQL Servr 2008 R2 is able to automatically match indexed view (also known as materialized views) that contain joins to a query? for example the view select dbo.Orders.Date, dbo.OrderDetails.ProductID from dbo.OrderDetails join dbo.Orders on dbo.OrderDetails.OrderID = dbo.Orders.ID cannot be automatically matched to the same exact query. When I select directly from this view ith (noexpand) I actually get a much faster query plan that does a scan on the clustered index of the indexed view. Can I get SQL Server to do this matching automatically? I have quite a few queries and views... I am on enterprise edition of SQL Server 2008 R2.

  • Programmatically selecting file in explorer

    - by flashk
    In my application I can programmatically open explorer and select a file using the following code: void BrowseToFile(LPCTSTR filename) { CString strArgs; strArgs = _T("/select,\""); strArgs += filename; strArgs += _T("\""); ShellExecute(0, _T("open"), _T("explorer.exe"), strArgs, 0, SW_NORMAL); } My problem is that if I call this function a second time with a different file, but in the same folder, the selection in explorer does not change to the new file, but remains on the previous file. For example, if I call my function with C:\path\to\file1.txt, a new explorer window will open and file1.txt will be selected. If I call my function a second time with C:\path\to\file2.txt, the existing explorer window will be activated, but the selection will still be on file1.txt. Is there a way to force explorer to update the selection or a better way to accomplish this?

  • Where to put conditionals in ANSI-syntax SQL queries

    - by RenderIn
    What's the difference between these two queries? I've been resistant to jumping on the ANSI-syntax bandwagon because I have not been able to unravel various syntactical ambiguities. Is 1) returning the product of the join and only then filtering out those joined records which have weight = 500? And is 2) filtering out those prior to the join? Is 2 bad syntax? Why might I use that? 1: SELECT SOMETHING FROM FOO INNER JOIN BAR ON FOO.NAME = BAR.NAME WHERE BAR.WEIGHT < 500 2: SELECT SOMETHING FROM FOO INNER JOIN BAR ON FOO.NAME = BAR.NAME AND BAR.WEIGHT < 500

  • Is the UIDatePicker really the best iPhone UI mechanism for selecting dates?

    - by BeachRunnerJoe
    Hello! I'm diving into iPhone/iPad development and I'm trying to find an elegant mechanism for allowing the user to select dates. It seems to me that a calendar control would be the best way to go, but I don't see one in anywhere in the SDK. All all I see is this overblown, the-price-is-right-looking DatePicker control. Is this the only control that comes with UIKit for allowing the user to select dates? What about the calendar that the Notes app uses? Also, I should note I'm really trying to avoid using 3rd party code frameworks that have little or no documentation, because I'm new to all this and sufficient documentation is a must at this point. Thanks so much in advance for all your wisdom!

  • What are the different ways to texture a terrain?

    - by ApocKalipsS
    I'm working with XNA on a 3D Game, and I'm trying to have a proper and nice environnement. I actually followed a tutorial to create a terrain from a Heightmap, and to texture it, I just apply a grass texture on it and tile it a number of times. But what I want to do is to have a really realistic texturing, but also generate it automatically (for example if I want to use a perlin noise to generate a terrain and then texture it). I already learnt about multi-texturing, loading a map file with different colors for different textures, but I don't think this is really efficient, for instance for cliffs or very steep areas it will tile a texture badly as it's a view from the top. Also I don't know how i'll draw roads or dirt paths with that. I hope you understood me despite my english! If you don't, basically, here what I want to do: How do I texture a randomly generated terrain? :) Thank you for your answers!

  • SQL Server union selects built dynamically from list of words

    - by Adam Tuttle
    I need to count occurrence of a list of words across all records in a given table. If I only had 1 word, I could do this: select count(id) as NumRecs where essay like '%word%' But my list could be hundreds or thousands of words, and I don't want to create hundreds or thousands of sql requests serially; that seems silly. I had a thought that I might be able to create a stored procedure that would accept a comma-delimited list of words, and for each word, it would run the above query, and then union them all together, and return one huge dataset. (Sounds reasonable, right? But I'm not sure where to start with that approach...) Short of some weird thing with union, I might try to do something with a temp table -- inserting a row for each word and record count, and then returning select * from that temp table. If it's possible with a union, how? And does one approach have advantages (performance or otherwise) over the other?
