c++ - A method of creating simple game GUI -


I am able to get a lot of information on the real logic development for the game. I would really like to create a card game, but how can I not just understand the position of the mouse, an object can be selected (or at least in the right way) before I thought of Boxing Boxing , But all my bitmaps are not rectangular. I then thought that f hides a hidden buffer with a different color of each object, but it seems that it has to do this way. I am wondering how this is actually done. For example, how do Adobe Flash know the object under the mouse?

Thank you

Your question is how to tell that the mouse is non- Above the rectangular bitmap. I'm assuming that all your bitmaps are really rectangular, but they have transparent areas. Depending on the scheme you use, you should first be able to tell the transparent part of your (rectangular) bitmap in any way (for example if you consider color to be transparent or if you use a little mask ) You will also know the bitmap's z-order (layering) on ​​your canvas. Then when you find a click on position (X, Y), you need to find a list of rectangular bitmaps on that pixel. Sort them by z-order and check for each if the pixel is transparent or not. If so, go to the next bitmap if not, then this is the selected bitmap

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
