I’ve decided to add file IO to my railroad game program. As always, every thing I do requires some new way to look at things. MFC provides serialization and I’m using MFC at the moment. The program only uses it for the user interface until now. Serialization is…
Continue readingThe Microsoft Foundation Classes are fairly useful. I don’t have experience with any other framework for comparison but MFC it better than writing all of the message handling code by hand. The problem with MFC is that they give you plenty of rope to hang yourself. I’m adding…
Continue readingI am at the point where I am programming the code to handle train-waypoint activities. The trains now look ahead for waypoints and brake at the appropriate time to reach the desired waypoint speed at the right place related to the waypoint. This is all cool because you…
Continue readingI was working last night on train routing and came across a serious dilemma; if a train splits in two, there is a new train that didn’t exist when the player first set routing information for the original train. What about a train that is created that has…
Continue readingThe code is still far from optimal but the track network traversal and linear distance computations are working correctly. I haven’t tested a train with cars facing in both forward and reverse directions but the code is all written to handle it. It’s a lot of code for…
Continue readingI have a working sample of the code I mentioned in an older blog post. I have a self-propelled train car that moves along any unending track layout. When the front wheels of the train car passes over a turnout, a random choice is made by this train…
Continue readingThis quick article describes a mechanism of data hiding that I have been using with some success. Data hiding is a mechanism where information in an object is not accessible to users of the object and, more importantly, not visible to users of the object. Some data hiding…
Continue readingI wrote some code and then had an epiphany. A minor one but one that made me realize I had approached something in the wrong way. It was not much code and can be reused with the new idea. First, the requirement is that the train move in…
Continue readingI just figured out why the concept of realistic train management was giving me trouble. I really hadn’t tried to figure it out in any detail before and as soon as I did, the problems became obvious. First A real railroad can do things that would be considered…
Continue readingI am providing this code in C# for a Visual Studio 2010 add-in to set the caption of the Visual Studio window based on information in the solution. All of the other code samples I found, all two of them, are only partially usable. My VS Solution always…
