• Game Technologies: DirectX, XNA, XACT, etc. My 2D game layer Editor and XNA to PictureBox question

  I started to build my "2D game layer editor", if you want you can see the interface of the application at this link: http://www.tonigreco.it/_XNA_/Editor.jpg The question is: can I draw to PictureBox area using XNA framework And if yes, how Feel free also to post here your general ideas about how to making this kind of editor.

• Visual C# How to Save/open data to/from a file

  Hi, I have a Rich Text Box and I want to save the text in that Text Box to a file. What I want is when the user finish entering data in the Text Box, then they press the "Save" button, then the SaveFileDialog would popups and let the user save the data to a text file anywhere they want to. The user can also re-open that file and then the data would populate the Text Box. How do I go about that, please help!! Thanks Jason You can retrieve the text data using either the Text or Rtf properties. The former returns raw text while the latter returns RTF text. In both cases you need only send it to a file. You can load the box with data by setting these properties as well. To display the Open/Save dialogs create an in ...Show All

• Visual C++ std::vector::resize bug

  This is the declaration for the second form of std::vector::resize (in VC 2005): void resize( size_type _Newsize , Type _Val ); Note it passes by value, not by const reference. This is different to every other function in std::vector, and means you cannot construct a vector of items marked with __declspec( align( n ) ). I modified the vector header to use a const reference instead and it seems to work fine now. The Intel C Compiler does not seem to have this problem, and I've just checked the GCC header and it passes by const reference. I can't really see any reason why you'd want to pass by value, so I'm presuming this really is a bug. Does anyone in MS read these forums cfp c_f_p w ...Show All

• Visual C# program running problem

  hi, i have a problem with running my program. when i trace my codes, the program is able to run according to what i planned. but when i run without tracing, the program will skip 2 lines of codes. can anyone advise on what i can do thanx. hi, i've solved the problem by replacing the problematic line(method) by adding the contents of the methods into the codes. i believe the problem is due to another class declared in the method that clashes with the class declared in my codes. i have another problem which i need advise on, how can i trigger an event manually from a method. i have to trigger a button click event which consist of my "save file" codes. i understand that i can't simply call the ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Generate random numbers for every class instance

  I'm trying out some AI techniques but I'm having a problem generating a TRULY random number. I create 20 instances of an ant class that should move and change directions on a random basis. They are doing that, but all in unison instead of each changing directions at different times. Its like synchronized ants. Anyone know how to create a truly random number each time the ants use this method Random r = new Random (); if (r.Next(100) < 5) ant.Speed = new Microsoft.Xna.Framework. Vector3 (-ant.Speed.X, ant.Speed.Y, ant.Speed.Z); if (r.Next(500) < 2) ant.Speed = new Microsoft.Xna.Framework.

• Visual J# Importing external jars to use in J#

  hi, sorry if this is explained somewhere and i just can't find it... i can see the min. requirements to *develop* the games, but what are the min. requirements to *play* the games we develop i can't get my game to run on any machine but my own. either .net isn't there (and *won't* install either), or they're not running WinXP. it seems like getting our games out there isn't very easy. the funny thing is, my PC doesn't support XNA completely -- i can only draw sprites, no 3D stuff -- so i made a simple game that's only using sprites. that means even something this simple isn't running on any machine but mine ! it's going to be hard to generate interest in our games if noone else can play them... finally, shouldn't the "r ...Show All
