• Game Technologies: DirectX, XNA, XACT, etc. Render target save'n'restore

  I've a func that do some work including rendering into rt. So, i need to save old rt at the beginning of my rendering, and then restore it at the end ( when smb call my func, he may have rendering to texture enabled, or just rendering to the backbuffer, and he don't wont to worry about restoring his rt after call of my func ). Is there any way to implement such a behaviour using XNA On the Xbox, there is only a single render target. "Render to texture" is done by rendering to this target, then using an ultra-fast memory copy into the texture area. Thus, if you really need to save the screen render target, you have to do something like: 1) copy current screen to texture 2) render your stuff 3) ren ...Show All

• .NET Development Resolution of DateTime.AddSeconds()

  The documentation says that the value parameter, which is a number of whole and fractional seconds, is rounded to the nearest tick (100 ns, or 0.0000001 s). However, my experience shows that it is rounded to the nearest millisecond. If you run the following code (C++ 2005, .Net 2.0): DateTime MyDT , NewDT ; __int64 diff ; MyDT = DateTime ( 2006 , 1 , 1 , 1 , 1 , 1 ); NewDT = MyDT . AddSeconds ( 0.1234567 ); diff = NewDT . Ticks - MyDT . Ticks ; Console :: WriteLine ( L "Difference #1: {0}" , diff ); you would see that effect. Is this a bug, a case of incorrect documentation,  or am I missing something Kamen If only this were the only instance of wasted time for this exact same reas ...Show All

• Visual Basic BackgroundWorker unhandled error

  Hi, I'm having trouble with BackgroundWorker. I have some code in the BackgroundWorker_DoWork() event that can raise an error. According to the BackgroundWorker documentation, errors raised in BackgroundWorker_DoWork() should be captured by BackgroundWorker_RunWorkerCompleted() event and appear in the events args as e.Error . But when I try this, every time my code raises an error, the debugger says its an unhandled exception. I've tried the MSDN example and again the debugger arcs up. I've even tried the solution from a C# post which was to make sure that checking of e.Error was the first line in the BackgroundWorker_RunWorkerCompleted() event - still no joy... Any suggestions Hi, no bugs here. Decora ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Strange effect when using translation

  I have a strange problem when I'm trying to move one model around. When the model is in the center of the camera it look okay ( http://www.marmalad.com/milan/sample1.jpg ) but when I place it away from the center (let's say to the right) the model seems to be rotating as well ( http://www.marmalad.com/milan/sample2.jpg ). I would like to ask why is this happening Why is the model rotating when I'm just using translation Thx in advance. I'm absolutely sure that it was because of the culling machanism and XNA actually uses right-handed coordinate system by default. Proof (MSDN XNA FAQ page): What coordinate system does the XNA Framework use The XNA Framework uses a right-handed coordinate system ...Show All
